Chapter 110 Conferred God!Locate Tianyuan! (Please subscribe!)
On the business jet apron near the head of runway 23 of Jianchuan Airport, a handsome white-painted Gulfstream business jet has finished all preparations before take-off and is waiting for the departure time to approach.
Since each flight of a business jet requires approval, the takeoff time is fixed and cannot be advanced.There is no way, the boss came too early, so I can only wait.
In the cockpit, the two pilots slumped on their seats bored.Originally, in this situation, they should be chatting all over the place, but the cockpit door is open, and it would be bad for the boss behind to hear them if they chatted too happily.
Business jet pilots are relatively idle, with an estimated workload of more than 100 hours a year.Compared with the nearly [-]-hour experience of airline pilots, it's not good for health.
Unlike airline pilots who are paid by the hour, business jet pilots are paid a fixed salary.If business jet pilots are also paid by the hour, they can fly more than 100 hours a year and still earn a hammer.Therefore, business jet pilots are basically on a buyout system, flying more and flying less, and only so much money a year.
In terms of cost performance alone, business jets are quite high, and it is a very good place for pilots who like to dawdle.
Just when the two pilots were in a panic, a voice suddenly came from the release frequency: "N254DC, turn to 121.55, frequency test."
Because every flight of a business jet needs to be specially approved, there must be no regular flight number, so the call sign is usually replaced by the aircraft number.
The pilots looked at each other, but the co-pilot on the right seat complied with the clearance control requirements, and changed the frequency to 121.55: "Let's go, N254DC!"
"N254DC, how often do you listen to my signal?" Soon the sound of control came from the earphone.
"Five!"
"Okay, now you can switch back to release frequency 121.7."
The co-pilot didn't turn back immediately, but asked a little strangely: "Excuse me, why are you suddenly doing a frequency test now?"
Generally speaking, the frequency test will only be carried out when the frequency is reopened in the morning, but what time is it, do you need to open a new frequency?
A large airport like Jianchuan has various frequencies for approach, control tower, ground, apron, clearance, and on-site command.But in the wee hours of the morning, when there are so few flights, it would be wasteful to run all these frequencies as usual.
Usually, the approach frequency is fixed.The tower frequency is sometimes combined with the clearance frequency, and the ground and apron frequencies are combined to allocate resources reasonably.
And from [-]:[-] in the morning, the number of flights has gradually increased, and the frequency of closures will be reopened one after another.When turned on, the controller will randomly select a crew for frequency testing.
It is indeed rare to conduct frequency tests in broad daylight like this.
The crew in the business jet is also in a panic. This is not something that the pilot should care about. If the airport wants to test the frequency, it will test and report to the crew?
However, the airport did not hide it, and said directly: "This is the spare frequency of the airport, and it will be activated in a while. N254DC switches back to the release line 121.7 and waits for a long time."
"121.7, N254DC!" The co-pilot didn't ask any more questions, and after switching back to the frequency, he reported: "Let's go, 121.7, I'll stay with you for a long time."
"N254DC, long-term guard frequency!" The release frequency continued: "All aircraft in the frequency are prohibited from calling the 121.55 frequency for the next hour. Repeat it again, and the 121.55 frequency is prohibited for the next hour!"
The same applies not only to clearance frequencies, but also to ramp, ground and tower frequencies.This is not aimed at a certain crew, but a broadcast call for all aircraft.
"121.55?" The co-pilot was a little puzzled: "What's wrong with this frequency, it seems that something happened."
The captain also showed a pensive expression: "Some crews will chat on 121.55, and now it seems that the airport will temporarily use 121.55 exclusively, which is a bit strange."
Sometimes when you are flying, you will hear the voices of familiar people on the radio, but it is okay to chat with the control frequency for a few words. If there are too many, it will be annoying, and you may even be sued by the control unit.Usually no one talks on the emergency frequency, but it seems that it is not good to occupy the emergency frequency.
Therefore, witty pilots will agree on the frequency of chatting.For example, airlines will have their own agreed frequencies, and airports will also have corresponding frequencies, like the backup frequency 121.55 of Jianchuan Airport.
Many acquainted pilots chatted in 121.55 when they met at Jianchuan Airport. Jianchuan Airport must know about it, but it doesn't matter.That is to say, it is quite humane to remind the crew not to call 121.55 at special times.
Just as the co-pilot was still wondering what happened, his eyes suddenly narrowed.The nose of the plane was facing runway 23, and it was very close. He could clearly see that the normal brightness of the runway lighting system began to brighten suddenly, which was very conspicuous even under the sun.
"No, what do you want to do at the airport, the brightness blinds your eyes." The co-pilot muttered.
The brightness of the light is not as high as possible. If it is too bright, it will affect the pilot's judgment of the relative position of the aircraft, which is extremely unfavorable.Like the situation outside, it is obvious that the lights have been adjusted to the highest brightness, but this kind of operation can only be done in low-visibility situations. How can this kind of operation be done in a cloudless day?
"It's so strange, it's really so strange." If the abnormality can't be found up to now, then the captain is in vain. He showed a hint of excitement and urged the co-pilot: "Use the second part to call out the frequency of the tower. , Let’s see if something really happened.”
The co-pilot was also very curious, so he hurried to check the tower frequency.However, suddenly, the two of them seemed to have sensed something, and they both turned their heads to see that Qin Xin was standing at the entrance of the cockpit, and the expressions on their faces froze.
Qin Xin asked coldly, "What happened?"
At this moment, the crew car carrying Luo Yong, Yu Fengtian and others has successfully passed the security check. The airport has greeted the security checkpoint, and the clearance is very smooth.
After passing the security check, the crew car sent Luo Yong and others all the way to the bottom of the control tower.The area near the control tower is a control area, and the crew cars cannot drive in, so they can only park nearby to let everyone get off.
The airport sent someone to come over, and when they saw Luo Yong approaching, they immediately greeted him: "Mr. Luo, come quickly, thank you for making the trip."
"Where, where, Director Liu has to worry about my own affairs." The person who came to pick them up was the director of the tower control room, whom Luo Yong knew.Sometimes, the airline company will associate with the airport group to enhance the relationship. Luo Yong still knows some people in the airport, but the personal relationship is relatively ordinary.
Director Liu glanced at Yu Fengtian, Li Rongcheng and Ye Xian who were following up, and said, "There are still a lot of people."
"This is our company's vice president of maintenance, and the next two Boeing staff. You also know that we wet-leased this plane from Muhua. We don't know much about it. To be honest, can you help me? We are busy, we have no idea." Luo Yong worried.
On this point, Director Liu expressed his understanding.Even for giant companies like the three major airlines, the number of Boeing 747s is small, far less than the large 737 fleet.
If the number is small, the accumulated experience will definitely be less.Regarding the aircraft, it is not possible to understand it by studying the manual below. It is all summed up by the operation of a large number of flights.
"It's okay, let's do our best." Director Liu and Luo Yong said as they walked, "According to the crew report just now, in addition to the captain and co-pilot on duty, three passengers were also injured in the cabin. The situation does not seem to be serious. .”
"That's good, that's good!" In any case, people are always the most important, as long as people are okay, many issues can be discussed.But once something happens to someone, even if the plane is fine, it will be a big deal.
Everyone followed Director Liu to take the ladder to the control room on the top of the tower. During the period, Director Liu was a little strange: "Just now we received the news from the Qianzhou District Control Office that the crew asked us to open a separate communication frequency, and the runway Turn all the lights to the brightest. Mr. Luo, do you know the reason for this?"
To be honest, it is understandable to open up a separate communication frequency. It may be that the crew has too much workload and does not want to waste time on communication.However, it is rather strange to adjust the runway lights to the brightest. The highest level of brightness is extremely dazzling even in the daytime, but it is not conducive to the pilot's landing.
Luo Yong thought for a moment but couldn't figure out what Xu Cang wanted to do. The way of turning the lights to the brightest was really weird.
When everyone went to the control room, through the glass, they could have a panoramic view of most of Jianchuan Airport, and the brightened runway lights were even more dazzling, even from a long distance away.
Luo Yong couldn't help frowning: "It's too bright, can you see the runway clearly when it lands?"
As he said that, Luo Yong looked at Director Liu in puzzlement: "Are you sure that the crew requires the highest level of brightness, did you hear me wrong?"
"I'm sure I didn't hear it wrong. I also found it strange, so I asked you."
At this moment, a control seat next to Director Liu said: "Director, the communication has been transferred!"
"Huh?" Director Liu was stunned: "Give me the microphone!"
Everyone realized that 9811 had connected to the airport frequency, and immediately surrounded the control group. The signal point of 9811 could already be seen on the radar screen. It was less than [-] nautical miles away from the field, and it had already entered the approach area. It will be landing soon.
"Lantian 9811, radar guidance now, blind landing on the 23rd, is it okay to fly to 030 now?" Director Liu said quickly.
9811 was silent for a long time, and when everyone was getting impatient, a woman's voice answered: "No, we apply for an approach according to the procedure, and SXS-1Y will enter the field."
Director Liu was taken aback. He remembered that the information he got was that the current operator on the plane was Xu Cang. He should be a man. Why did he answer that it was a woman?
However, he didn't pay much attention to it. Maybe Xu Cang was too busy, so he asked the flight attendant to take the seat to help with the communication, which is not so rare.It's just that he didn't quite understand why he had to follow the standard approach procedure to land, obviously because the speed of radar guidance was faster.
Since it might be a flight issue, Director Liu didn't give an answer immediately, but looked at Luo Yong.
Luo Yong grabbed the microphone: "SXS-1Y needs to go through a long five-sided approach. It takes too long. We must land quickly and fly to 030 according to the instruction just now. The radar guide intercepts the blind landing."
However, the answer was much faster this time, and it was still the woman's voice: "No, we can only fly standard instrument procedures."
Luo Yong was already on fire, and he couldn't figure out what the hell Xu Cang was doing, so he shouted: "It's fun to stay in the sky, isn't it? Don't let a flight attendant talk to me, where is Xu Cang? You should give me one." Reason, what is the purpose of flying standard approach procedures?"
After another period of silence, the person on the other side spoke again: "Mr. Luo, I am Xia Shuyue from the No. [-] Flight Attendant Squadron. My brother said that he is now invisible and cannot follow the instructions to precisely control the aircraft. He can only fly according to the standard approach procedure." .”
As soon as this remark came out, everyone was in an uproar.Luo Yong was trembling all over, and a layer of cold sweat oozed from his back.He and Director Liu looked at each other in blank dismay. He didn't say that even Xu Cang's body was in trouble!
Apparently, Director Liu heard this news for the first time, and a trace of panic appeared on his face.The pilot couldn't see it, so how could he bring the plane down?
"What the hell is going on here, where is Xu Cang? Let him talk to me!" Luo Yong became anxious, and his voice raised unconsciously.
"Mr. Luo, my brother had bleeding in his eyes when he released the pressure." Xia Shuyue continued: "Also, his ears are also bleeding, and his hearing is very bad. Sometimes I need to repeat it to him. If possible, can it be brief, or I may not remember it."
"This..." Luo Yong's hand could hardly hold the microphone steadily. He supported the table with one hand, trying to stabilize his figure, trying to keep himself calm in such a shocking message.
What kind of joke is it that a blind man and a half-deaf man land a jumbo airliner?
And Yu Fengtian, who was on the periphery, was about to collapse on the ground when he heard the news that Xu Cang could not see and could not hear.This is not basically a death sentence for the plane. If the plane crashes and it is finally found out that the source of everything is caused by the defect of the S2 switch, then he is not as simple as just submitting his resignation letter.
On the contrary, Ye Xian showed surprise on his face, while Li Rongcheng was expressionless, and he didn't know what he was thinking about.
As if catching a glimmer of life, Luo Yong hurriedly said: "Xu Cang, you command that flight attendant to switch to autopilot, is she in good health?"
This time the frequency was completely quiet, and it was so weird that it made people feel a little scary.
Suddenly, a frosty voice sounded on the frequency: "Are you asking me to hand over the entire plane to a flight attendant who doesn't understand anything? Do you trust her, or the automatic landing function of the 747?"
In fact, Xu Cang also considered letting Xia Shuyue control the plane instead of him, after all, the autopilot is still available.However, after thinking about it, Xu Cang still rejected this idea.Not to mention, can Xia Shuyue understand his command? He hasn't even made approach preparations yet. If he wants to approach with autopilot, he not only needs to adjust the MCP board, but also needs to set the course, decision altitude, and navigation frequency. Wait, he didn't have time to do all of this.
If any one of these links is wrong, the plane will undoubtedly die.Xu Cang can't see it now, and can't verify whether Xia Shuyue is doing right or not. The risk is too great, so big that Xu Cang has already regarded it as impossible.
Moreover, another reason why Xu Cang objected to letting Xia Shuyue come was the poor automatic landing function of the Boeing 747.If it was Xia Shuyue who came for the approach, it would definitely have to land by autopilot in the end, but as far as Xu Cang knew, the autolanding of the 747-400 was not yet perfect, and it would be relatively reliable after many versions were updated.How could Xu Cang pin his hopes on an unreliable automatic landing function.
Luo Yong shouted: "Then how do you land, you can't see how to land? Not to mention leveling, you can't even guide the plane over the runway!"
After waiting for a while on the frequency, Xu Cang replied again: "So, I need to fly according to the standard approach procedure, and I will use the vertical navigation to guide the plane over the runway."
"No!" The voice came from Director Liu, who took Luo Yong's microphone: "Xu Cang, do you mean RNP APCH? But the PBN operation is still in the test state, and the area navigation routes on the route are not fully completed. Let go, let alone the RNP1 part of the approach phase. Xu Cang, our airport does not have RNP procedures, if you want to fly with vertical navigation, you cannot guarantee safety."
"It's okay!" Director Liu's voice was so loud that Xu Cang could understand without Xia Shuyue's recitation: "Even if there is no RNP procedure, the FMC will calculate and simulate a descent profile during the final approach stage. Just press that to fly."
"However, that has not been verified." Director Liu obviously understands some cutting-edge PBN technology: "The descent profile calculated according to B-VNAV does not match the blind descent glide path, and it is greatly affected by temperature. Large, there are terrain risks."
"It's okay, that's safe!" Xu Cang's attitude was extremely firm.
Of course he knew it was safe, because this technology was verified by Boeing for a full ten years later, and it was promoted to the world after it was confirmed to be absolutely safe, that is, the RNP APCH commonly used in later generations and the further precision-like RNP AR technology.
However, the technology is now in the testing phase around the world.It was only two years ago that Europe tried to use basic area navigation technology for the first time, and China only tested PBN technology in a few air routes.
The P554 point given by the Qianzhou government just now is located by the PBN technology.
The traditional route is based on the navigation platform. Because of the necessity of the navigation platform, the airspace utilization of the route will be greatly restricted.The PBN technology uses the WGS84 coordinate system as a means of navigation, and defines a waypoint with latitude and longitude, so that it is not restricted by the navigation station.
In this way, the utilization rate of airspace will be greatly improved.Of course, in this era, few people can understand this technology, and it is rare for Director Liu to know a little bit.
"This..." Seeing Xu Cang's extremely firm attitude, Director Liu didn't know what to say, so he had to look at Luo Yong and ask for his opinion.
Luo Yong gritted his teeth and took the microphone: "Xu Cang, even if you can guide the plane over the runway, how do you level off? This approach method cannot be connected to an automatic landing."
Automatic landing can only be continued in the way of blind landing approach, so the final leveling action still cannot be completed.
"I didn't plan to use automatic landing either." After waiting for a while, Xu Cang's attitude became even more unshakable: "Just use vertical navigation to guide the plane to the sky above the runway, as long as I guide it there, I can land, that's all !"
"Damn it!" Luo Yong inserted his hand into his hair, he only felt a splitting headache, Xu Cang was as smelly and hard as a stone in a latrine.
On the other hand, Li Rongcheng's eyes flickered in the back. He didn't expect Xu Cang to be so familiar with PBN, an extremely cutting-edge navigation technology, which is quite rare.
At this moment, in the cockpit, Xu Cang dropped the earphones casually, took a deep breath and confirmed with Xia Shuyue again: "Remember the airspeed, altitude and heading I taught you just now, do you know where it is? ?”
"Yes, I know. The airspeed indicator is on the left, the altimeter is on the right, and the heading indicator is on the bottom. It's like a compass. I remember." Xia Shuyue nodded.
Xu Cang breathed a sigh of relief, this was the limit that Xia Shuyue could understand.It took Xu Cang a while just now to let Xia Shuyue understand where is the airspeed indicator, where is the altimeter, and where is the heading indicator.Just reading these basic data has consumed almost all of Xu Cang's energy.Luo Yong tried in vain to let him reappear to teach Xia Shuyue how to approach, it was ridiculous.
If it were so easy to learn, pilots wouldn't be so valuable!
The reason why Xia Shuyue had to read the airspeed, altitude and heading data was because even though the horizontal navigation and vertical navigation can guide the plane over the runway, and even automatically adjust the speed, the establishment of the landing configuration needs to be done manually. of.This is Xu Cang who can do it by himself.
Although it can't be seen, it is enough to put the landing gear handle down, and there is a slot on the side of the flap handle, so you can probably know how many flaps it is by touching it.
Xu Cang needs to confirm the airspeed to establish the landing configuration, and at the same time verify the altitude and heading to verify that the aircraft is indeed flying according to the standard instrument approach procedure.
Suddenly a strange feeling flashed in Xu Cang's heart. After switching to the frequency of Jianchuan Airport, the plane should be very close to this field, probably only twenty or thirty nautical miles away.
I talked to the controller just now. According to the speed of the plane, it should turn to the third right side at this time.
According to Xu Cang's memory, the plane should have approached the field from the direction of the west mountain, and its heading was just facing the field, and then turned right about 1 nautical miles away from the field, joined a right three-way, and flew towards the starting point of SXS-[-]Y. The near fix point is added to the approach procedure.
It feels like it should be turning right now.
"Shuyue, where are we flying now?" Xu Cang asked.
Xia Shuyue looked at the navigation page and studied it for a long time, and said with some uncertainty: "It seems to be facing a small green circle."
Xu Cang's heart skipped a beat, the small green circle was the positioning point of Jianchuan Airport, and he typed it in himself.He asked urgently, "Is the plane still following the red line now?"
The red line is the effective route and approach procedure. As long as the aircraft is still on the red line, it means that there is no problem with the aircraft for the time being.
However, Xia Shuyue said: "Brother, there is no more! It just flew towards that small green circle."
Xu Cang's face changed wildly, and he held the steering wheel tightly with his left hand, without saying a word.
Xia Shuyue thought that her voice was too low, and Xu Cang's hearing was damaged, so she couldn't hear it, so she said loudly, "Brother, I didn't fly along the red line."
"I heard it." Xu Cang took a deep breath, but Xia Shuyue next to him could hear Xu Cang's breathing trembling slightly.He patted Xia Shuyue: "Hurry up and contact the control, let them locate our location."
Xu Cang didn't understand why the plane didn't follow the procedure according to the horizontal navigation, he only knew that now the plane deviated from the procedure, then the RNP APCH was all empty talk, and he didn't even know where the plane was now.
Xu Cang can't expect Xia Shuyue to understand the content on the navigation page.
Although she didn't understand what happened, but looking at Xu Cang's dignified face, Xia Shuyue probably knew that the situation was not very good, so she was busy calling the control.However, after calling several times in a row, the other party did not answer.
"Brother, they didn't reply!?" Xia Shuyue became a little nervous.
Xu Cang was also a little panicked at this time, if there was another communication failure, without the help from the ground, they would undoubtedly make things worse.Xu Cang stretched out his right hand, groped for a while on the communication panel, and switched the transmitter by feeling: "Try again."
Xia Shuyue nodded, and called a few more times, but there was still no answer.
Now Xia Shuyue really panicked: "Brother, there is no sound, what should I do?"
At this moment, even Xu Cang felt a trace of despair in his heart.Recalling, maybe when I inputted the CDU just now, because I was worried about temporary blindness, I didn’t connect the last point of the route with the initial approach fix point of the approach procedure due to the fear of temporary blindness, which led to the disconnection of the aircraft. Just out of the program.
Of course, what is the reason is not important anymore, what is important is what to do now?
Once the plane deviated from the program, Xu Cang didn't even dare to go down the altitude, because flying according to the program has terrain protection, as long as the altitude limit in the program is followed one by one, there will be no problem.
But now it's not in the program, and Xu Cang doesn't know what's below, what should I do if I hit the mountain at a high altitude indiscriminately?If you want to deviate from the altitude under the procedure, you need the permission of the controller, because the controller can see the terrain effect, and he will help the crew to evaluate it.However, now they can't even get in touch with the control, and they really have nowhere to go.
Not to mention flying over the runway, he doesn't even know where he is now!
"Could it be that I really have to explain here this time?" Xu Cang's mind unexpectedly had this idea unstoppable.
Even though she didn't understand the current situation, Xia Shuyue could feel the change in Xu Cang's face, and she couldn't help asking: "Brother, what should we do?"
Xia Shuyue's voice was getting weaker and weaker. Xu Cang knew that his hearing was still weakening, and he probably wouldn't be able to hear anything soon.At that point, it's really a dead end.
Time to make a decision!
"If there is no program, then I will just come up with a program!" Xu Cang gritted his teeth, he had too much load on his back, he couldn't just die here so simply!
Relying on the airspeed, altitude and heading that Xia Shuyue can provide, as well as the approach procedure map memorized in his mind, Xu Cang is trying to figure out an approach procedure in the center of this desperate situation!
Well, first he needs to know where he is!
"Keep flying forward!" Xu Cang said coldly.
Xia Shuyue was startled: "Where did you fly to?"
Xu Cang took a deep breath: "That small circle, let's start from there!"
At this moment, in the tower control room of Jianchuan Airport, everyone is watching the signal point 9811 fly along the SXS-1Y procedure on the radar screen.However, at the turning point on the third right side, the aircraft did not turn right to the initial approach fix, but kept flying forward.
"What's the matter, why didn't the plane fly according to the procedure?" Director Liu was taken aback, and patted the controller on the shoulder: "The crew just said to follow the SXS-1Y procedure, didn't I hear it wrong?"
"Director, what the crew said just now is to approach the airport according to SXS-1Y." The controller confirmed.
"Then why doesn't he turn?" Director Liu pointed to the controller's microphone: "Call the crew and ask about the situation."
However, before the controller could speak, Xia Shuyue's voice sounded instead: "Control tower, Lantian 9811!"
Director Liu quickly patted the controller on the shoulder: "Hurry up and ask them if they have changed their intention to enter the venue?"
The controller nodded, and immediately asked into the microphone: "Lantian 9811, you have deviated from SXS-1Y now, do you want to change the approach procedure?"
At this moment, the people around were all listening, but after waiting for a while, the crew did not answer at all, but continued to ask: "Tower, Lantian 9811, can you hear me?"
"Lantian 9811, I listen to your signal five." The controller immediately replied.
However, it was the slightly nervous Xia Shuyue's voice that replied to the controller: "Control tower, please call back, we want to confirm the position of the plane."
There were only three incidents, and everyone, including Li Rongcheng and Ye Xian behind, all changed their expressions wildly, while Luo Yong was in a daze for a long time, and after a long pause, he said in disbelief: "Is there something wrong with their receiving antenna?"
The voice of the crew can be heard from the control side, but the crew can't hear the controller's reply. It can basically be concluded that the aircraft's receiving equipment is out of order.
In fact, it is also possible that there is a problem with the transmitter on the control side, but the probability is too small.
When the crew could not see and their ears could barely hear, the aircraft's receiving antenna failed, which meant that the crew could not get help from the controller at all.
What's more terrible is that now that the aircraft has deviated from the standard procedure, the autopilot cannot guide the aircraft to the predetermined position above the runway.
"They just said they want us to report the position of their plane, that is to say." Director Liu looked at Luo Yong with horror on his face: "The crew doesn't know where they are now!? How could this happen? The plane should have navigation instruments!"
Yu Fengtian's teeth were almost bleeding: "But people who can understand the navigation instruments can't see it now!"
"No, no, no! This won't work. I can't see the sight, and I can't see the instruments. How did the plane land? Did you fly blind? Rayong, Rayong! You fucking think of a way!" Director Liu almost collapsed, and he was in the control room of the control tower. He has been working for a full ten years, and he is about to be promoted to the Air Traffic Management Bureau. In any case, there must be no flight accidents during his tenure.Otherwise, his official career is over!
Luo Yong's face was livid, how could he think of a way, what can he do?
Seeing Luo Yong's helplessness, Director Liu burst into anger, grabbed Luo Yong by the collar, and roared in a low voice: "There is one month left, and I will be transferred to the Air Traffic Management Bureau in one month. If all this happens, if I ruin it, don't think about it!"
Luo Yong's expression changed suddenly. Seeing Director Liu's eagerness to eat him alive, he knew that Director Liu was really joking.If flight 9811 really crashed today, as the director of the tower control room, not to mention being responsible, it must be a big stain on his career, and it would be wishful thinking to want to re-enter the Air Traffic Management Bureau.
But Luo Yong knew that Director Liu had been waiting for ten years to be transferred to the Air Traffic Management Bureau, and when his dream was shattered, all Blue Sky aircraft departing from Jianchuan Airport in the future might suffer a catastrophe!
"Director Liu, you can't do this, and we don't want this to happen." Luo Yong quickly explained.
"What about me?" Director Liu roared, "I can't control that much, you have to take responsibility for what happened to your company! If this plane crashes, if there are any delays and traffic control in the future, you Blue Sky Airlines will be the last one." one!"
Director Liu's roar almost filled the entire control tower control room, and what he said was obviously a public revenge, which was very inappropriate.But the controllers in the dispatch room all lowered their heads, pretending not to hear.
After waiting for a full ten years, everyone will go crazy if they become disillusioned!
Luo Yong's face turned pale in an instant.There is no airline that is unwilling to establish a good relationship with the director of the control room of the airport control tower. Even a company like the three major airlines will send various gifts to the control room every holiday, and treat guests to dinner from time to time, just to maintain Relationship with dispatch room.
As a result, Blue Sky Airlines didn't have a good relationship, and directly offended the person in charge of the control room to death.Then in the foreseeable future, Blue Sky Airlines will be unable to move at Jianchuan Airport.
"Turn to 121.5 and continue to call!" Director Liu had already put down his harsh words, and he didn't bother to argue anymore, and asked the controller to try to call the 9811 unit on the emergency frequency.
However, before the controller could make a sound, Xu Cang’s deep and stern voice came to mind on the emergency frequency 121.5: “Lantian 9811 communication failure is now sending a message blindly! This plane is expected to land at Jianchuan Airport in 10 minutes. Vision and hearing problems, and the navigation equipment cannot be used at the same time, please all aircraft on taxiway A, all exit lanes, and runways of Jianchuan Airport to leave as soon as possible! I repeat, because the operators on board have vision and hearing problems, and at the same time The navigation equipment cannot be used, and the landing accuracy will not be guaranteed, please all aircraft on taxiway A, exit lane and runway of Jianchuan Airport to disengage as soon as possible, and stay away from the corresponding area.”
As soon as this remark came out, the audience in the control room was in an uproar.During the communication failure, if it is only a one-way failure, it is possible to try to send a blind message to inform the controller of the intention.The 121.5 emergency frequency is monitored by all aircraft and control units, and the blind transmission range is the widest in this frequency.
Xu Cang didn't have time to verify whether it was a two-way communication failure or a one-way failure, he just did everything he could.
Blind posting itself is not uncommon, what is scary is the content of blind posting.Director Liu muttered in a daze: "What do you mean, is he planning to crash?"
To clear the runway and the taxiways adjacent to the runway, it is clear that the crew has no confidence to land on the runway.It is to evacuate all people and aircraft in the nearby area, so as not to harm innocent people.
This is very bad news, and it seems that the crew is also in a desperate situation.
Luo Yong and Yu Fengtian looked at each other, and they both saw endless fear in each other's eyes.As long as this plane crashes, Blue Sky Airlines will also be finished.
Regardless of personal grievances now, Yu Fengtian now hopes that Xu Cang can land the plane more than anyone else.
Director Liu let out a sigh of relief. He really wanted to curse and vent his inner anger, but he knew there were more important things to do.
He turned his head and pointed to his assistant: "Notify the clearance and the apron to suspend the rollout of the plane, and ask the ground to recall all the taxiing planes. In addition, the airport firefighting and emergency medical services, hurry up!"
After finishing speaking, Director Liu gave Luo Yong a hard look, which was self-evident.
At the same time, on the Gulfstream business jet, Xu Cang's blind message was also received, and Qin Xin, who was standing at the door of the cockpit, listened to everything verbatim.
The two pilots present didn't notice Qin Xin's complexion darkened rapidly, and they were still talking about the blind hair.
"Why did the crew have hearing and vision problems?" The captain was a little surprised: "Could it be that the airport uses the spare frequency exclusively for him?"
The co-pilot clicked his tongue: "Brother, this person said that the navigation equipment is useless, how did this plane land? You can't see it, you can't hear it, and the navigation equipment is still useless. How can this be done?"
"What else are you doing?" The captain sneered, "They're dead, I don't know how it happened!"
However, the moment the captain's voice fell, there was some movement from behind.The captain and co-pilot who were chatting vigorously were surprised to realize that Qin Xin was at the door.
When the captain smiled dryly and turned his head to look at Qin Xin, he saw Qin Xin's pretty face was pale, exuding a chill all over his body.
"Old boss?" The captain instinctively felt that something was wrong with Qin Xin's state.
"Can you find out the flight crew information of Blue Sky Airlines?" Qin Xin asked in a low voice.
"This." The captain was a little apprehensive: "Checking the airline's flight plan requires employee authority, and I can't check it. However, someone I know in Blue Sky Airlines can help check it. Boss, what do you want to check?"
Qin Xin's voice became colder and colder: "Lantian 9811!"
Xu Cang's blind message spread to almost all aircraft and control units in the country through the emergency frequency, and the information revealed in it surprised the listeners. Some people actually landed without being seen, heard, and without instruments. , This is simply impossible beyond the limits of human beings.
However, there are still countless crews who have begun to inquire about Blue Sky 9811.All, all eyes on this epic show!
The dispatch room of Jianchuan Airport was filled with a dignified atmosphere, and the landline on the duty desk had been ringing since Xu Cang sent a blind message, but Director Liu insisted on not letting anyone pick it up.
He didn't need to answer the calls to know who was calling and what they were asking for.
Even if he answered the phone one by one, if the plane crashed, he would still have the same result.The only thing that can save him now is that 9811 can land safely.
But looking at Luo Yong and Yu Fengtian who were sweating profusely, Director Liu's last illusion was shattered.
No sight, no smell, no gauges!
Director Liu let out a long sigh. Without instrument navigation and visual reference, how would the plane fly to the fifth side?Without program protection, the plane can't go down the altitude at all, because it may hit the mountain at any time!Even if you fly to the final side, fly over the runway, you can't see the runway, and you can't hear the report of the radio altimeter, how will the plane level off?
One by one, the fundamentally unsolvable problems were placed in front of Director Liu, telling the doomed ending time and time again like the whispers of the devil.
Li Rongcheng, who had not spoken all this time, looked serious, and he let out a sigh of relief: "Xu Cang, what will you do?"
"How and where are they going to fly?" Director Liu asked feebly.He didn't know who to ask, and now the crew didn't even know where he was, so it was a dead end.
"They're going to the airport!" Suddenly, a voice tinged with excitement rang in everyone's ears, and it came from Ye Xian, who hadn't spoken for a long time.
I saw him licking his dry lips and staring at the radar screen: "They don't know their location, so they need to locate first, and the airport is his positioning point!"
"But even if they fly to the airport, how can they fly afterwards without instrument support and visual reference!" Director Liu asked back.
However, Ye Xian was trembling all over: "He doesn't have instruments and vision, but he has airspeed and heading, so he can figure out a way!"
Ye Xian's eyes burst out with an incomparably bright light, and the blood in his body seemed to be boiling. He could hardly help screaming: "Xu Cang, can you do it? Can you achieve this miracle that surpasses human beings?" ?”
Brothers, it's Riwan again!
When will everyone be able to push me to become the best seller on the channel, even for a day!The number one best-selling reality channel is not high, everyone give a little help.
If it is the best seller tomorrow, no matter how many words, I will write this climax for you tomorrow, so there is no need to stop.
Everyone, give me some strength and let me be the first.
(End of this chapter)
On the business jet apron near the head of runway 23 of Jianchuan Airport, a handsome white-painted Gulfstream business jet has finished all preparations before take-off and is waiting for the departure time to approach.
Since each flight of a business jet requires approval, the takeoff time is fixed and cannot be advanced.There is no way, the boss came too early, so I can only wait.
In the cockpit, the two pilots slumped on their seats bored.Originally, in this situation, they should be chatting all over the place, but the cockpit door is open, and it would be bad for the boss behind to hear them if they chatted too happily.
Business jet pilots are relatively idle, with an estimated workload of more than 100 hours a year.Compared with the nearly [-]-hour experience of airline pilots, it's not good for health.
Unlike airline pilots who are paid by the hour, business jet pilots are paid a fixed salary.If business jet pilots are also paid by the hour, they can fly more than 100 hours a year and still earn a hammer.Therefore, business jet pilots are basically on a buyout system, flying more and flying less, and only so much money a year.
In terms of cost performance alone, business jets are quite high, and it is a very good place for pilots who like to dawdle.
Just when the two pilots were in a panic, a voice suddenly came from the release frequency: "N254DC, turn to 121.55, frequency test."
Because every flight of a business jet needs to be specially approved, there must be no regular flight number, so the call sign is usually replaced by the aircraft number.
The pilots looked at each other, but the co-pilot on the right seat complied with the clearance control requirements, and changed the frequency to 121.55: "Let's go, N254DC!"
"N254DC, how often do you listen to my signal?" Soon the sound of control came from the earphone.
"Five!"
"Okay, now you can switch back to release frequency 121.7."
The co-pilot didn't turn back immediately, but asked a little strangely: "Excuse me, why are you suddenly doing a frequency test now?"
Generally speaking, the frequency test will only be carried out when the frequency is reopened in the morning, but what time is it, do you need to open a new frequency?
A large airport like Jianchuan has various frequencies for approach, control tower, ground, apron, clearance, and on-site command.But in the wee hours of the morning, when there are so few flights, it would be wasteful to run all these frequencies as usual.
Usually, the approach frequency is fixed.The tower frequency is sometimes combined with the clearance frequency, and the ground and apron frequencies are combined to allocate resources reasonably.
And from [-]:[-] in the morning, the number of flights has gradually increased, and the frequency of closures will be reopened one after another.When turned on, the controller will randomly select a crew for frequency testing.
It is indeed rare to conduct frequency tests in broad daylight like this.
The crew in the business jet is also in a panic. This is not something that the pilot should care about. If the airport wants to test the frequency, it will test and report to the crew?
However, the airport did not hide it, and said directly: "This is the spare frequency of the airport, and it will be activated in a while. N254DC switches back to the release line 121.7 and waits for a long time."
"121.7, N254DC!" The co-pilot didn't ask any more questions, and after switching back to the frequency, he reported: "Let's go, 121.7, I'll stay with you for a long time."
"N254DC, long-term guard frequency!" The release frequency continued: "All aircraft in the frequency are prohibited from calling the 121.55 frequency for the next hour. Repeat it again, and the 121.55 frequency is prohibited for the next hour!"
The same applies not only to clearance frequencies, but also to ramp, ground and tower frequencies.This is not aimed at a certain crew, but a broadcast call for all aircraft.
"121.55?" The co-pilot was a little puzzled: "What's wrong with this frequency, it seems that something happened."
The captain also showed a pensive expression: "Some crews will chat on 121.55, and now it seems that the airport will temporarily use 121.55 exclusively, which is a bit strange."
Sometimes when you are flying, you will hear the voices of familiar people on the radio, but it is okay to chat with the control frequency for a few words. If there are too many, it will be annoying, and you may even be sued by the control unit.Usually no one talks on the emergency frequency, but it seems that it is not good to occupy the emergency frequency.
Therefore, witty pilots will agree on the frequency of chatting.For example, airlines will have their own agreed frequencies, and airports will also have corresponding frequencies, like the backup frequency 121.55 of Jianchuan Airport.
Many acquainted pilots chatted in 121.55 when they met at Jianchuan Airport. Jianchuan Airport must know about it, but it doesn't matter.That is to say, it is quite humane to remind the crew not to call 121.55 at special times.
Just as the co-pilot was still wondering what happened, his eyes suddenly narrowed.The nose of the plane was facing runway 23, and it was very close. He could clearly see that the normal brightness of the runway lighting system began to brighten suddenly, which was very conspicuous even under the sun.
"No, what do you want to do at the airport, the brightness blinds your eyes." The co-pilot muttered.
The brightness of the light is not as high as possible. If it is too bright, it will affect the pilot's judgment of the relative position of the aircraft, which is extremely unfavorable.Like the situation outside, it is obvious that the lights have been adjusted to the highest brightness, but this kind of operation can only be done in low-visibility situations. How can this kind of operation be done in a cloudless day?
"It's so strange, it's really so strange." If the abnormality can't be found up to now, then the captain is in vain. He showed a hint of excitement and urged the co-pilot: "Use the second part to call out the frequency of the tower. , Let’s see if something really happened.”
The co-pilot was also very curious, so he hurried to check the tower frequency.However, suddenly, the two of them seemed to have sensed something, and they both turned their heads to see that Qin Xin was standing at the entrance of the cockpit, and the expressions on their faces froze.
Qin Xin asked coldly, "What happened?"
At this moment, the crew car carrying Luo Yong, Yu Fengtian and others has successfully passed the security check. The airport has greeted the security checkpoint, and the clearance is very smooth.
After passing the security check, the crew car sent Luo Yong and others all the way to the bottom of the control tower.The area near the control tower is a control area, and the crew cars cannot drive in, so they can only park nearby to let everyone get off.
The airport sent someone to come over, and when they saw Luo Yong approaching, they immediately greeted him: "Mr. Luo, come quickly, thank you for making the trip."
"Where, where, Director Liu has to worry about my own affairs." The person who came to pick them up was the director of the tower control room, whom Luo Yong knew.Sometimes, the airline company will associate with the airport group to enhance the relationship. Luo Yong still knows some people in the airport, but the personal relationship is relatively ordinary.
Director Liu glanced at Yu Fengtian, Li Rongcheng and Ye Xian who were following up, and said, "There are still a lot of people."
"This is our company's vice president of maintenance, and the next two Boeing staff. You also know that we wet-leased this plane from Muhua. We don't know much about it. To be honest, can you help me? We are busy, we have no idea." Luo Yong worried.
On this point, Director Liu expressed his understanding.Even for giant companies like the three major airlines, the number of Boeing 747s is small, far less than the large 737 fleet.
If the number is small, the accumulated experience will definitely be less.Regarding the aircraft, it is not possible to understand it by studying the manual below. It is all summed up by the operation of a large number of flights.
"It's okay, let's do our best." Director Liu and Luo Yong said as they walked, "According to the crew report just now, in addition to the captain and co-pilot on duty, three passengers were also injured in the cabin. The situation does not seem to be serious. .”
"That's good, that's good!" In any case, people are always the most important, as long as people are okay, many issues can be discussed.But once something happens to someone, even if the plane is fine, it will be a big deal.
Everyone followed Director Liu to take the ladder to the control room on the top of the tower. During the period, Director Liu was a little strange: "Just now we received the news from the Qianzhou District Control Office that the crew asked us to open a separate communication frequency, and the runway Turn all the lights to the brightest. Mr. Luo, do you know the reason for this?"
To be honest, it is understandable to open up a separate communication frequency. It may be that the crew has too much workload and does not want to waste time on communication.However, it is rather strange to adjust the runway lights to the brightest. The highest level of brightness is extremely dazzling even in the daytime, but it is not conducive to the pilot's landing.
Luo Yong thought for a moment but couldn't figure out what Xu Cang wanted to do. The way of turning the lights to the brightest was really weird.
When everyone went to the control room, through the glass, they could have a panoramic view of most of Jianchuan Airport, and the brightened runway lights were even more dazzling, even from a long distance away.
Luo Yong couldn't help frowning: "It's too bright, can you see the runway clearly when it lands?"
As he said that, Luo Yong looked at Director Liu in puzzlement: "Are you sure that the crew requires the highest level of brightness, did you hear me wrong?"
"I'm sure I didn't hear it wrong. I also found it strange, so I asked you."
At this moment, a control seat next to Director Liu said: "Director, the communication has been transferred!"
"Huh?" Director Liu was stunned: "Give me the microphone!"
Everyone realized that 9811 had connected to the airport frequency, and immediately surrounded the control group. The signal point of 9811 could already be seen on the radar screen. It was less than [-] nautical miles away from the field, and it had already entered the approach area. It will be landing soon.
"Lantian 9811, radar guidance now, blind landing on the 23rd, is it okay to fly to 030 now?" Director Liu said quickly.
9811 was silent for a long time, and when everyone was getting impatient, a woman's voice answered: "No, we apply for an approach according to the procedure, and SXS-1Y will enter the field."
Director Liu was taken aback. He remembered that the information he got was that the current operator on the plane was Xu Cang. He should be a man. Why did he answer that it was a woman?
However, he didn't pay much attention to it. Maybe Xu Cang was too busy, so he asked the flight attendant to take the seat to help with the communication, which is not so rare.It's just that he didn't quite understand why he had to follow the standard approach procedure to land, obviously because the speed of radar guidance was faster.
Since it might be a flight issue, Director Liu didn't give an answer immediately, but looked at Luo Yong.
Luo Yong grabbed the microphone: "SXS-1Y needs to go through a long five-sided approach. It takes too long. We must land quickly and fly to 030 according to the instruction just now. The radar guide intercepts the blind landing."
However, the answer was much faster this time, and it was still the woman's voice: "No, we can only fly standard instrument procedures."
Luo Yong was already on fire, and he couldn't figure out what the hell Xu Cang was doing, so he shouted: "It's fun to stay in the sky, isn't it? Don't let a flight attendant talk to me, where is Xu Cang? You should give me one." Reason, what is the purpose of flying standard approach procedures?"
After another period of silence, the person on the other side spoke again: "Mr. Luo, I am Xia Shuyue from the No. [-] Flight Attendant Squadron. My brother said that he is now invisible and cannot follow the instructions to precisely control the aircraft. He can only fly according to the standard approach procedure." .”
As soon as this remark came out, everyone was in an uproar.Luo Yong was trembling all over, and a layer of cold sweat oozed from his back.He and Director Liu looked at each other in blank dismay. He didn't say that even Xu Cang's body was in trouble!
Apparently, Director Liu heard this news for the first time, and a trace of panic appeared on his face.The pilot couldn't see it, so how could he bring the plane down?
"What the hell is going on here, where is Xu Cang? Let him talk to me!" Luo Yong became anxious, and his voice raised unconsciously.
"Mr. Luo, my brother had bleeding in his eyes when he released the pressure." Xia Shuyue continued: "Also, his ears are also bleeding, and his hearing is very bad. Sometimes I need to repeat it to him. If possible, can it be brief, or I may not remember it."
"This..." Luo Yong's hand could hardly hold the microphone steadily. He supported the table with one hand, trying to stabilize his figure, trying to keep himself calm in such a shocking message.
What kind of joke is it that a blind man and a half-deaf man land a jumbo airliner?
And Yu Fengtian, who was on the periphery, was about to collapse on the ground when he heard the news that Xu Cang could not see and could not hear.This is not basically a death sentence for the plane. If the plane crashes and it is finally found out that the source of everything is caused by the defect of the S2 switch, then he is not as simple as just submitting his resignation letter.
On the contrary, Ye Xian showed surprise on his face, while Li Rongcheng was expressionless, and he didn't know what he was thinking about.
As if catching a glimmer of life, Luo Yong hurriedly said: "Xu Cang, you command that flight attendant to switch to autopilot, is she in good health?"
This time the frequency was completely quiet, and it was so weird that it made people feel a little scary.
Suddenly, a frosty voice sounded on the frequency: "Are you asking me to hand over the entire plane to a flight attendant who doesn't understand anything? Do you trust her, or the automatic landing function of the 747?"
In fact, Xu Cang also considered letting Xia Shuyue control the plane instead of him, after all, the autopilot is still available.However, after thinking about it, Xu Cang still rejected this idea.Not to mention, can Xia Shuyue understand his command? He hasn't even made approach preparations yet. If he wants to approach with autopilot, he not only needs to adjust the MCP board, but also needs to set the course, decision altitude, and navigation frequency. Wait, he didn't have time to do all of this.
If any one of these links is wrong, the plane will undoubtedly die.Xu Cang can't see it now, and can't verify whether Xia Shuyue is doing right or not. The risk is too great, so big that Xu Cang has already regarded it as impossible.
Moreover, another reason why Xu Cang objected to letting Xia Shuyue come was the poor automatic landing function of the Boeing 747.If it was Xia Shuyue who came for the approach, it would definitely have to land by autopilot in the end, but as far as Xu Cang knew, the autolanding of the 747-400 was not yet perfect, and it would be relatively reliable after many versions were updated.How could Xu Cang pin his hopes on an unreliable automatic landing function.
Luo Yong shouted: "Then how do you land, you can't see how to land? Not to mention leveling, you can't even guide the plane over the runway!"
After waiting for a while on the frequency, Xu Cang replied again: "So, I need to fly according to the standard approach procedure, and I will use the vertical navigation to guide the plane over the runway."
"No!" The voice came from Director Liu, who took Luo Yong's microphone: "Xu Cang, do you mean RNP APCH? But the PBN operation is still in the test state, and the area navigation routes on the route are not fully completed. Let go, let alone the RNP1 part of the approach phase. Xu Cang, our airport does not have RNP procedures, if you want to fly with vertical navigation, you cannot guarantee safety."
"It's okay!" Director Liu's voice was so loud that Xu Cang could understand without Xia Shuyue's recitation: "Even if there is no RNP procedure, the FMC will calculate and simulate a descent profile during the final approach stage. Just press that to fly."
"However, that has not been verified." Director Liu obviously understands some cutting-edge PBN technology: "The descent profile calculated according to B-VNAV does not match the blind descent glide path, and it is greatly affected by temperature. Large, there are terrain risks."
"It's okay, that's safe!" Xu Cang's attitude was extremely firm.
Of course he knew it was safe, because this technology was verified by Boeing for a full ten years later, and it was promoted to the world after it was confirmed to be absolutely safe, that is, the RNP APCH commonly used in later generations and the further precision-like RNP AR technology.
However, the technology is now in the testing phase around the world.It was only two years ago that Europe tried to use basic area navigation technology for the first time, and China only tested PBN technology in a few air routes.
The P554 point given by the Qianzhou government just now is located by the PBN technology.
The traditional route is based on the navigation platform. Because of the necessity of the navigation platform, the airspace utilization of the route will be greatly restricted.The PBN technology uses the WGS84 coordinate system as a means of navigation, and defines a waypoint with latitude and longitude, so that it is not restricted by the navigation station.
In this way, the utilization rate of airspace will be greatly improved.Of course, in this era, few people can understand this technology, and it is rare for Director Liu to know a little bit.
"This..." Seeing Xu Cang's extremely firm attitude, Director Liu didn't know what to say, so he had to look at Luo Yong and ask for his opinion.
Luo Yong gritted his teeth and took the microphone: "Xu Cang, even if you can guide the plane over the runway, how do you level off? This approach method cannot be connected to an automatic landing."
Automatic landing can only be continued in the way of blind landing approach, so the final leveling action still cannot be completed.
"I didn't plan to use automatic landing either." After waiting for a while, Xu Cang's attitude became even more unshakable: "Just use vertical navigation to guide the plane to the sky above the runway, as long as I guide it there, I can land, that's all !"
"Damn it!" Luo Yong inserted his hand into his hair, he only felt a splitting headache, Xu Cang was as smelly and hard as a stone in a latrine.
On the other hand, Li Rongcheng's eyes flickered in the back. He didn't expect Xu Cang to be so familiar with PBN, an extremely cutting-edge navigation technology, which is quite rare.
At this moment, in the cockpit, Xu Cang dropped the earphones casually, took a deep breath and confirmed with Xia Shuyue again: "Remember the airspeed, altitude and heading I taught you just now, do you know where it is? ?”
"Yes, I know. The airspeed indicator is on the left, the altimeter is on the right, and the heading indicator is on the bottom. It's like a compass. I remember." Xia Shuyue nodded.
Xu Cang breathed a sigh of relief, this was the limit that Xia Shuyue could understand.It took Xu Cang a while just now to let Xia Shuyue understand where is the airspeed indicator, where is the altimeter, and where is the heading indicator.Just reading these basic data has consumed almost all of Xu Cang's energy.Luo Yong tried in vain to let him reappear to teach Xia Shuyue how to approach, it was ridiculous.
If it were so easy to learn, pilots wouldn't be so valuable!
The reason why Xia Shuyue had to read the airspeed, altitude and heading data was because even though the horizontal navigation and vertical navigation can guide the plane over the runway, and even automatically adjust the speed, the establishment of the landing configuration needs to be done manually. of.This is Xu Cang who can do it by himself.
Although it can't be seen, it is enough to put the landing gear handle down, and there is a slot on the side of the flap handle, so you can probably know how many flaps it is by touching it.
Xu Cang needs to confirm the airspeed to establish the landing configuration, and at the same time verify the altitude and heading to verify that the aircraft is indeed flying according to the standard instrument approach procedure.
Suddenly a strange feeling flashed in Xu Cang's heart. After switching to the frequency of Jianchuan Airport, the plane should be very close to this field, probably only twenty or thirty nautical miles away.
I talked to the controller just now. According to the speed of the plane, it should turn to the third right side at this time.
According to Xu Cang's memory, the plane should have approached the field from the direction of the west mountain, and its heading was just facing the field, and then turned right about 1 nautical miles away from the field, joined a right three-way, and flew towards the starting point of SXS-[-]Y. The near fix point is added to the approach procedure.
It feels like it should be turning right now.
"Shuyue, where are we flying now?" Xu Cang asked.
Xia Shuyue looked at the navigation page and studied it for a long time, and said with some uncertainty: "It seems to be facing a small green circle."
Xu Cang's heart skipped a beat, the small green circle was the positioning point of Jianchuan Airport, and he typed it in himself.He asked urgently, "Is the plane still following the red line now?"
The red line is the effective route and approach procedure. As long as the aircraft is still on the red line, it means that there is no problem with the aircraft for the time being.
However, Xia Shuyue said: "Brother, there is no more! It just flew towards that small green circle."
Xu Cang's face changed wildly, and he held the steering wheel tightly with his left hand, without saying a word.
Xia Shuyue thought that her voice was too low, and Xu Cang's hearing was damaged, so she couldn't hear it, so she said loudly, "Brother, I didn't fly along the red line."
"I heard it." Xu Cang took a deep breath, but Xia Shuyue next to him could hear Xu Cang's breathing trembling slightly.He patted Xia Shuyue: "Hurry up and contact the control, let them locate our location."
Xu Cang didn't understand why the plane didn't follow the procedure according to the horizontal navigation, he only knew that now the plane deviated from the procedure, then the RNP APCH was all empty talk, and he didn't even know where the plane was now.
Xu Cang can't expect Xia Shuyue to understand the content on the navigation page.
Although she didn't understand what happened, but looking at Xu Cang's dignified face, Xia Shuyue probably knew that the situation was not very good, so she was busy calling the control.However, after calling several times in a row, the other party did not answer.
"Brother, they didn't reply!?" Xia Shuyue became a little nervous.
Xu Cang was also a little panicked at this time, if there was another communication failure, without the help from the ground, they would undoubtedly make things worse.Xu Cang stretched out his right hand, groped for a while on the communication panel, and switched the transmitter by feeling: "Try again."
Xia Shuyue nodded, and called a few more times, but there was still no answer.
Now Xia Shuyue really panicked: "Brother, there is no sound, what should I do?"
At this moment, even Xu Cang felt a trace of despair in his heart.Recalling, maybe when I inputted the CDU just now, because I was worried about temporary blindness, I didn’t connect the last point of the route with the initial approach fix point of the approach procedure due to the fear of temporary blindness, which led to the disconnection of the aircraft. Just out of the program.
Of course, what is the reason is not important anymore, what is important is what to do now?
Once the plane deviated from the program, Xu Cang didn't even dare to go down the altitude, because flying according to the program has terrain protection, as long as the altitude limit in the program is followed one by one, there will be no problem.
But now it's not in the program, and Xu Cang doesn't know what's below, what should I do if I hit the mountain at a high altitude indiscriminately?If you want to deviate from the altitude under the procedure, you need the permission of the controller, because the controller can see the terrain effect, and he will help the crew to evaluate it.However, now they can't even get in touch with the control, and they really have nowhere to go.
Not to mention flying over the runway, he doesn't even know where he is now!
"Could it be that I really have to explain here this time?" Xu Cang's mind unexpectedly had this idea unstoppable.
Even though she didn't understand the current situation, Xia Shuyue could feel the change in Xu Cang's face, and she couldn't help asking: "Brother, what should we do?"
Xia Shuyue's voice was getting weaker and weaker. Xu Cang knew that his hearing was still weakening, and he probably wouldn't be able to hear anything soon.At that point, it's really a dead end.
Time to make a decision!
"If there is no program, then I will just come up with a program!" Xu Cang gritted his teeth, he had too much load on his back, he couldn't just die here so simply!
Relying on the airspeed, altitude and heading that Xia Shuyue can provide, as well as the approach procedure map memorized in his mind, Xu Cang is trying to figure out an approach procedure in the center of this desperate situation!
Well, first he needs to know where he is!
"Keep flying forward!" Xu Cang said coldly.
Xia Shuyue was startled: "Where did you fly to?"
Xu Cang took a deep breath: "That small circle, let's start from there!"
At this moment, in the tower control room of Jianchuan Airport, everyone is watching the signal point 9811 fly along the SXS-1Y procedure on the radar screen.However, at the turning point on the third right side, the aircraft did not turn right to the initial approach fix, but kept flying forward.
"What's the matter, why didn't the plane fly according to the procedure?" Director Liu was taken aback, and patted the controller on the shoulder: "The crew just said to follow the SXS-1Y procedure, didn't I hear it wrong?"
"Director, what the crew said just now is to approach the airport according to SXS-1Y." The controller confirmed.
"Then why doesn't he turn?" Director Liu pointed to the controller's microphone: "Call the crew and ask about the situation."
However, before the controller could speak, Xia Shuyue's voice sounded instead: "Control tower, Lantian 9811!"
Director Liu quickly patted the controller on the shoulder: "Hurry up and ask them if they have changed their intention to enter the venue?"
The controller nodded, and immediately asked into the microphone: "Lantian 9811, you have deviated from SXS-1Y now, do you want to change the approach procedure?"
At this moment, the people around were all listening, but after waiting for a while, the crew did not answer at all, but continued to ask: "Tower, Lantian 9811, can you hear me?"
"Lantian 9811, I listen to your signal five." The controller immediately replied.
However, it was the slightly nervous Xia Shuyue's voice that replied to the controller: "Control tower, please call back, we want to confirm the position of the plane."
There were only three incidents, and everyone, including Li Rongcheng and Ye Xian behind, all changed their expressions wildly, while Luo Yong was in a daze for a long time, and after a long pause, he said in disbelief: "Is there something wrong with their receiving antenna?"
The voice of the crew can be heard from the control side, but the crew can't hear the controller's reply. It can basically be concluded that the aircraft's receiving equipment is out of order.
In fact, it is also possible that there is a problem with the transmitter on the control side, but the probability is too small.
When the crew could not see and their ears could barely hear, the aircraft's receiving antenna failed, which meant that the crew could not get help from the controller at all.
What's more terrible is that now that the aircraft has deviated from the standard procedure, the autopilot cannot guide the aircraft to the predetermined position above the runway.
"They just said they want us to report the position of their plane, that is to say." Director Liu looked at Luo Yong with horror on his face: "The crew doesn't know where they are now!? How could this happen? The plane should have navigation instruments!"
Yu Fengtian's teeth were almost bleeding: "But people who can understand the navigation instruments can't see it now!"
"No, no, no! This won't work. I can't see the sight, and I can't see the instruments. How did the plane land? Did you fly blind? Rayong, Rayong! You fucking think of a way!" Director Liu almost collapsed, and he was in the control room of the control tower. He has been working for a full ten years, and he is about to be promoted to the Air Traffic Management Bureau. In any case, there must be no flight accidents during his tenure.Otherwise, his official career is over!
Luo Yong's face was livid, how could he think of a way, what can he do?
Seeing Luo Yong's helplessness, Director Liu burst into anger, grabbed Luo Yong by the collar, and roared in a low voice: "There is one month left, and I will be transferred to the Air Traffic Management Bureau in one month. If all this happens, if I ruin it, don't think about it!"
Luo Yong's expression changed suddenly. Seeing Director Liu's eagerness to eat him alive, he knew that Director Liu was really joking.If flight 9811 really crashed today, as the director of the tower control room, not to mention being responsible, it must be a big stain on his career, and it would be wishful thinking to want to re-enter the Air Traffic Management Bureau.
But Luo Yong knew that Director Liu had been waiting for ten years to be transferred to the Air Traffic Management Bureau, and when his dream was shattered, all Blue Sky aircraft departing from Jianchuan Airport in the future might suffer a catastrophe!
"Director Liu, you can't do this, and we don't want this to happen." Luo Yong quickly explained.
"What about me?" Director Liu roared, "I can't control that much, you have to take responsibility for what happened to your company! If this plane crashes, if there are any delays and traffic control in the future, you Blue Sky Airlines will be the last one." one!"
Director Liu's roar almost filled the entire control tower control room, and what he said was obviously a public revenge, which was very inappropriate.But the controllers in the dispatch room all lowered their heads, pretending not to hear.
After waiting for a full ten years, everyone will go crazy if they become disillusioned!
Luo Yong's face turned pale in an instant.There is no airline that is unwilling to establish a good relationship with the director of the control room of the airport control tower. Even a company like the three major airlines will send various gifts to the control room every holiday, and treat guests to dinner from time to time, just to maintain Relationship with dispatch room.
As a result, Blue Sky Airlines didn't have a good relationship, and directly offended the person in charge of the control room to death.Then in the foreseeable future, Blue Sky Airlines will be unable to move at Jianchuan Airport.
"Turn to 121.5 and continue to call!" Director Liu had already put down his harsh words, and he didn't bother to argue anymore, and asked the controller to try to call the 9811 unit on the emergency frequency.
However, before the controller could make a sound, Xu Cang’s deep and stern voice came to mind on the emergency frequency 121.5: “Lantian 9811 communication failure is now sending a message blindly! This plane is expected to land at Jianchuan Airport in 10 minutes. Vision and hearing problems, and the navigation equipment cannot be used at the same time, please all aircraft on taxiway A, all exit lanes, and runways of Jianchuan Airport to leave as soon as possible! I repeat, because the operators on board have vision and hearing problems, and at the same time The navigation equipment cannot be used, and the landing accuracy will not be guaranteed, please all aircraft on taxiway A, exit lane and runway of Jianchuan Airport to disengage as soon as possible, and stay away from the corresponding area.”
As soon as this remark came out, the audience in the control room was in an uproar.During the communication failure, if it is only a one-way failure, it is possible to try to send a blind message to inform the controller of the intention.The 121.5 emergency frequency is monitored by all aircraft and control units, and the blind transmission range is the widest in this frequency.
Xu Cang didn't have time to verify whether it was a two-way communication failure or a one-way failure, he just did everything he could.
Blind posting itself is not uncommon, what is scary is the content of blind posting.Director Liu muttered in a daze: "What do you mean, is he planning to crash?"
To clear the runway and the taxiways adjacent to the runway, it is clear that the crew has no confidence to land on the runway.It is to evacuate all people and aircraft in the nearby area, so as not to harm innocent people.
This is very bad news, and it seems that the crew is also in a desperate situation.
Luo Yong and Yu Fengtian looked at each other, and they both saw endless fear in each other's eyes.As long as this plane crashes, Blue Sky Airlines will also be finished.
Regardless of personal grievances now, Yu Fengtian now hopes that Xu Cang can land the plane more than anyone else.
Director Liu let out a sigh of relief. He really wanted to curse and vent his inner anger, but he knew there were more important things to do.
He turned his head and pointed to his assistant: "Notify the clearance and the apron to suspend the rollout of the plane, and ask the ground to recall all the taxiing planes. In addition, the airport firefighting and emergency medical services, hurry up!"
After finishing speaking, Director Liu gave Luo Yong a hard look, which was self-evident.
At the same time, on the Gulfstream business jet, Xu Cang's blind message was also received, and Qin Xin, who was standing at the door of the cockpit, listened to everything verbatim.
The two pilots present didn't notice Qin Xin's complexion darkened rapidly, and they were still talking about the blind hair.
"Why did the crew have hearing and vision problems?" The captain was a little surprised: "Could it be that the airport uses the spare frequency exclusively for him?"
The co-pilot clicked his tongue: "Brother, this person said that the navigation equipment is useless, how did this plane land? You can't see it, you can't hear it, and the navigation equipment is still useless. How can this be done?"
"What else are you doing?" The captain sneered, "They're dead, I don't know how it happened!"
However, the moment the captain's voice fell, there was some movement from behind.The captain and co-pilot who were chatting vigorously were surprised to realize that Qin Xin was at the door.
When the captain smiled dryly and turned his head to look at Qin Xin, he saw Qin Xin's pretty face was pale, exuding a chill all over his body.
"Old boss?" The captain instinctively felt that something was wrong with Qin Xin's state.
"Can you find out the flight crew information of Blue Sky Airlines?" Qin Xin asked in a low voice.
"This." The captain was a little apprehensive: "Checking the airline's flight plan requires employee authority, and I can't check it. However, someone I know in Blue Sky Airlines can help check it. Boss, what do you want to check?"
Qin Xin's voice became colder and colder: "Lantian 9811!"
Xu Cang's blind message spread to almost all aircraft and control units in the country through the emergency frequency, and the information revealed in it surprised the listeners. Some people actually landed without being seen, heard, and without instruments. , This is simply impossible beyond the limits of human beings.
However, there are still countless crews who have begun to inquire about Blue Sky 9811.All, all eyes on this epic show!
The dispatch room of Jianchuan Airport was filled with a dignified atmosphere, and the landline on the duty desk had been ringing since Xu Cang sent a blind message, but Director Liu insisted on not letting anyone pick it up.
He didn't need to answer the calls to know who was calling and what they were asking for.
Even if he answered the phone one by one, if the plane crashed, he would still have the same result.The only thing that can save him now is that 9811 can land safely.
But looking at Luo Yong and Yu Fengtian who were sweating profusely, Director Liu's last illusion was shattered.
No sight, no smell, no gauges!
Director Liu let out a long sigh. Without instrument navigation and visual reference, how would the plane fly to the fifth side?Without program protection, the plane can't go down the altitude at all, because it may hit the mountain at any time!Even if you fly to the final side, fly over the runway, you can't see the runway, and you can't hear the report of the radio altimeter, how will the plane level off?
One by one, the fundamentally unsolvable problems were placed in front of Director Liu, telling the doomed ending time and time again like the whispers of the devil.
Li Rongcheng, who had not spoken all this time, looked serious, and he let out a sigh of relief: "Xu Cang, what will you do?"
"How and where are they going to fly?" Director Liu asked feebly.He didn't know who to ask, and now the crew didn't even know where he was, so it was a dead end.
"They're going to the airport!" Suddenly, a voice tinged with excitement rang in everyone's ears, and it came from Ye Xian, who hadn't spoken for a long time.
I saw him licking his dry lips and staring at the radar screen: "They don't know their location, so they need to locate first, and the airport is his positioning point!"
"But even if they fly to the airport, how can they fly afterwards without instrument support and visual reference!" Director Liu asked back.
However, Ye Xian was trembling all over: "He doesn't have instruments and vision, but he has airspeed and heading, so he can figure out a way!"
Ye Xian's eyes burst out with an incomparably bright light, and the blood in his body seemed to be boiling. He could hardly help screaming: "Xu Cang, can you do it? Can you achieve this miracle that surpasses human beings?" ?”
Brothers, it's Riwan again!
