Chapter 172 Death's Eyes Down!Change your life against the sky! (Please subscribe!)

"Active pressure release?" Tan Heling looked at Xu Cang incredulously: "You mean to manually release the pressure after wiping the tail? What if the plane exceeds [-] feet?"

"Then follow the decompression procedure." Xu Cang answered Tan Heling's question while paying attention to the status of the plane.

Although the situation is more dangerous this time, so far, the situation is finally under control.The limited pitch control caused certain difficulties, but on Xu Cang's side, this problem is still acceptable.

The more fatal problem is the damage to the fuselage at the tail. Fortunately, there is no ductility problem now. What Xu Cang pays more attention to is whether the damage to the tail will further cause the problem of pitch control.

The most frightening thing now is the complete failure of the elevator. After all, according to the control report, some parts have been separated. If more parts are separated, the consequences will be unimaginable.

In the turning operation, some additional means can be used to complete, such as ailerons, such as rudder.However, the rudder is mainly used for yaw operation, and the rudder only plays an auxiliary role in turning.

However, if aileron problems do occur, the rudder can still complete the turn of the aircraft to some extent.It's just that the efficiency is much lower than that of the aileron.

However, it is difficult to have a backup in the pitch operation, that is, if the elevator fails, the pilot cannot assist the pitch control through the movement of other rudder surfaces, and the only feasible solution is to increase or decrease the thrust.

It's just that the method of increasing or decreasing the thrust is difficult to achieve precise pitch control, even if Xu Cang is allowed to do it.

The only good news is that although it looked very dangerous, but the danger did not happen.If this state continues, it will not be very difficult for the plane to land.

It is precisely because of such a stable state of mind that Xu Cang has the spare energy to talk to Tan Heling about the issue of actively releasing pressure.

"You're saying that even if the plane doesn't decompress, but we have to open all the outflow valves directly, then once the plane rises above [-] feet, isn't that the incident that caused the decompression of the plane?" Tan Heling still couldn't understand Xu Cang Logic, isn't this asking for trouble for yourself?
However, Xu Cang did not waver: "Two evils are the lesser of two evils. In the case of possible damage to the fuselage, the existence of the supercharging system will aggravate the damage to the fuselage, so this danger must be eliminated. Lose."

"Even if the pressure is artificially relieved, is it okay?" Tan Heling asked rhetorically.

Xu Cang's eyes drooped slightly: "Boeing 737 does not have damage detection of the fuselage structure. As long as there is any doubt, it must be regarded as having occurred. The risk generated during the prepared decompression is compared with the damage to the fuselage. It’s just a drop in the bucket.”

Tan Heling was speechless for a moment, he himself felt that what Xu Cang said seemed to make sense.However, there is also an unavoidable problem.

"However, there is no related active pressure release procedure in the tail wiping procedure. You are violating the standard procedure."

Xu Cang's eyes shone brightly, which contained incomparable firmness: "So Boeing's operating manual needs to be revised."

Both Tan Heling and Mo Shangyun were shocked. What Xu Cang said clearly pointed out that Boeing's standard operating procedures were flawed.In this era, no matter whether it is from the bureau, the airline, or the pilots at the lowest level, although they scoff at Boeing's commercial practices, they have never denied its professionalism and regarded its operating procedures as the standard. How can they be like Xu Cang? Here it is said that the Boeing manual needs to be changed.

"Xu Cang, are you telling the truth?" Tan Heling still couldn't believe that Xu Cang dared to say that, not to mention that Xu Cang is now a second-level co-pilot, even the chief pilot of the Civil Aviation Administration would not dare to say this what.

However, Xu Cang did not answer Tan Heling's words directly, but said softly: "Don't worry, you will be fine. It's a problem with the program, not you."

Tan Heling's body trembled, Xu Cang clearly saw through his little thoughts.He asked so persistently because he was afraid that he had skipped the checklist and switched the pressurization mode to the manual position just now, and then completely closed the outflow valve.

From Xu Cang's point of view, the explosion of the plane was directly related to his manual closing of the outflow valve, and this was what Tan Heling was most disturbed about.But now Xu Cang said that Tan Heling was fine.

Even though Tan Heling knew that the final result was decided by the bureau, he was relieved when he heard Xu Cang say that, and said, "Thank you."

"Okay, let's get ready for the approach." Xu Cang adjusted his mood and continued: "The difficulty of landing this time is not too big, and the problem of limited pitch operation is still concentrated on the nose of the aircraft, so when approaching During the operation, try to be careful not to create a situation where the aircraft is too full of energy. Others are not a big problem."

Today the steering wheel is restricted to only being pushed forward or pulled back a short amount of travel, but that doesn't mean the plane is as difficult to nose down as it is to go up.

Since the stabilizer trim has been pushed forward to the bottom, the most direct way to lower the plane's head is to hold the steering wheel, but this method is limited.

On the contrary, if you want the aircraft to look up, although pulling the steering wheel back is also limited, you can assist in completing the aircraft's nose-up by turning the stabilizer back to trim, and this method is not limited so far.

Therefore, in view of the inconsistency in the difficulty of nose-down and nose-up of the plane, Xu Cang needs to try his best to avoid the possible situation that requires a large nose-down, which is what Xu Cang said is too much energy for the plane.

When the energy is too full and full, the pilot has to rely on uninterrupted ejection to keep the trajectory of the aircraft on the correct glide path, which is obviously inconsistent with the plight of today's aircraft.

"I will enter the field with a relatively small energy state. There may be three red lights and one white light or four red lights when I enter the runway at a low altitude. As long as the deviation of the aircraft status data is not particularly large, don't call for a go-around. We are now Pitch operation is limited, if possible, try not to go around."

It can be seen that Xu Cang is still prepared for the upcoming approach process.Generally speaking, under the reference of PAPI lights, two reds and two whites are naturally the most standard downward trajectory.

However, in actual flight, at low altitudes, such as when you are about to enter the sky above the runway, if you still follow the standard of two reds and two whites, then it is very likely that you will not fall on the "big white block", which is the standard touchdown area.

This is because the standard glide trajectory is indeed in the docking area, but the glide trajectory of the aircraft cannot be a straight line objectively, mainly because the aircraft has a flattened curve at the end.

If the aircraft is always facing the touchdown zone, it will almost certainly cross the touchdown zone once the final leveling is performed.Therefore, in the actual flight, the pilot will perform some additional operations, such as artificially lowering the plane when it is about to land, in order to lower the trajectory of the plane below the standard trajectory, so that the plane can be just right when it is leveled. Landed on the touchdown zone.

Another thing is to move the timing of this action forward, that is, abandon the standard glide track when entering the sky above the runway, and enter the field at a low altitude with three reds and one white. After that, the aircraft can be lowered without normal operation, so Grounding points will also be standard.

Xu Cang undoubtedly wanted to choose the latter method, because due to the limited state of pitch control, he might not be able to complete the action of lowering the plane at the last moment.So, what he has to do is to change the entry height and enter at a lower height.

Anyway, he can accept low energy and low altitude, but he cannot accept high energy and high altitude landing.

With Xu Cang's technology, it is reasonable to complete the PAPI lights three red and one white approach, but to avoid some unexpected situations, such as the approach height is too low and four red lights, Xu Cang still needs to communicate with Tan Heling and Mo Shang Yun explained to save those two people from calling a go-around due to the height of their approach.

It's not that the plane can't go around now, it's just that it's more troublesome, Xu Cang doesn't want to go around unless he has to.Moreover, the state of high thrust and high elevation angle for the go-around is relatively large for the aircraft, which may worsen the damaged state of the aircraft, which is the most fatal.

"Don't you care about the four red lights?" Tan Heling asked.

Xu Cang shook his head: "Don't worry! It's easy to correct when flying low, but difficult to correct when flying high. If it flies into four white lights, it's better to go around."

Now that Xu Cang said so, Tan Heling and Mo Shangyun have no objections, and they can understand Xu Cang's thoughts, so the three of them agree.

"Make preparations for the approach." Xu Cang ordered.

"Okay!" Tan Heling immediately made approach preparations. The preparations were not complicated. The course path and ILS frequency were adjusted before takeoff, and the decision altitude was the same.Tan Heling only needs to choose automatic braking.However, when the automatic brake is selected to three, the automatic brake disarm light is always on.

"Huh?" Tan Heling turned the automatic brake knob back to the off position, waited for three or four seconds, and then selected the automatic brake three gear again.After waiting for a few more seconds, the disarming light of the automatic brake came on again.

Tan Heling tried again, but the result was still the same.

Xu Cang was still paying attention to the control of the plane. After Tan Heling tried to set the automatic brake several times to no avail, he finally noticed it and asked casually, "Is there a problem with the automatic brake?"

"It seems that it can't be set." Tan Heling set the automatic brake again in front of Xu Cang, but the disarming light still stubbornly turned on.

Xu Cang tried it himself, but the result was still the same, so he simply ignored it: "Forget it, it's the same when I use the manual brake."

"Oh, it's ready." Tan Heling quickly scanned the panel from top to bottom to confirm that the settings have been completed: "Then I should make a quick briefing?"

Just as Xu Cang wanted to agree, Mo Shangyun who was sitting behind said, "Xu Cang, how do you feel about the pole strength?"

"Rod strength? No." Xu Cang raised his eyebrows, and quickly realized the meaning of Mo Shangyun's words. He quickly freed his right hand, pressed the SYS button, and immediately displayed the engine data on the lower DU. Display hydraulic information.

When the hydraulic page appeared, Xu Cang's eyelids twitched.

"The hydraulic pressure is decreasing?" Tan Heling who was beside him approached: "It's dropping so fast! Instructor, is it because the hydraulic pressure is decreasing that the automatic brake cannot be armed?"

"The pressure of system B is directly related to automatic braking. However, this is not the biggest problem." Mo Shangyun's tone was normal: "It's not that the hydraulic pressure is decreasing, it's that the hydraulic oil is leaking out."

Xu Cang cursed secretly, and Tan Heling also reacted: "Is the tail damaged and connected to the hydraulic pipe?"

"Otherwise?" Mo Shangyun sighed: "A damaged fuselage will cause so many problems."

Whether it is hydraulic pipelines, fuel pipelines or electrical pipelines, they are all distributed on the fuselage structure. As long as physical damage occurs, the damage will inevitably extend to other systems, not just the problem of pressurization. .

There was an explosion not long ago, but any normal person can understand that the damage to the fuselage structure will be extremely serious, and it is not unimaginable that the damage will spread.

Tan Heling watched the pressure of the AB system drop rapidly, and couldn't help but worry: "Xu Cang, do you still have difficulty in controlling it?"

The rudder surface control of the Boeing 737 uses hydraulic pressure to eliminate excess stick force. Once the hydraulic system fails, the pilot must directly control the rudder surface through the mechanical structure, and the force required is very large.

Xu Cang moved the steering wheel a little bit, feeling that the situation is okay now: "It's okay, let's land as soon as possible, who knows what other problems will happen?"

In Xu Cang's mind, the failure of the hydraulic system is not difficult to deal with. Even if all the AB systems fail, it will be a big deal to restore the flight manually.

The difficulty of manual flight recovery has never been technical, but the pilot's strength is not enough.That's right, once it enters the artificial recovery state, the pilot basically directly controls the flight control surface with the help of the lack of hydraulic pressure. Under the action of the aerodynamic load, the force of the control stick will be very large. At that time, the aircraft is really "airborne". Gym".

However, now that the plane is about to land, if you want to keep fit, it won't last very long, even with Xu Cang's body, he can still stand it.

What Xu Cang was worried about was those unknown malfunctions, such as the deterioration of the pitch control, so landing as soon as possible was the most important thing.

At this moment, Director Liu's voice came again from the tower control frequency: "Xu Cang, is the plane in good condition?"

"There are some minor problems with the hydraulic pressure, but the whole is still controllable."

"Okay!" Director Liu breathed a sigh of relief when he heard that everything was normal, "Then you continue to descend to an altitude of 500 meters."

500 meters is the height of the final approach fix for runway 05. According to the procedure, the glideslope should be intercepted at this height.

"Okay." Xu Cang didn't even complete the recitation, his eyes scanned the dashboard for a moment, and finally located on the supercharger panel.

At this moment, the cabin of the aircraft is already connected to the outside world, so whatever the altitude outside is, the altitude of the cockpit is also the same.However, the altitude of the aircraft was below [-] feet at this moment, but the cockpit altitude warning light was still on.

Tan Heling noticed that Xu Cang was looking at the cockpit altitude warning light, and asked: "The altitude should be less than [-], should I take off the oxygen mask? The warning light is delayed."

"Wait a while." Of course Xu Cang knew that there would be a delay in extinguishing the cockpit altitude warning light. The main reason why he hadn't taken off the oxygen mask was that he had already begun to feel the sluggish stick force.

"Damn it!" Just now, Xu Cang pulled the steering wheel slightly backwards, but it felt smooth two or three minutes ago, but now it feels like driving in the mud, only showing extremely subtle Reaction.

Xu Cang knew that it was not stuck again, but that the hydraulic pressure had dropped to a limit value, so he began to directly control the rudder surface through the mechanical structure of the cable.

If there was no such problem, Xu Cang estimated that the oxygen mask would be removed as soon as the plane descended below [-] feet, but let's wait now.

At this altitude, the air is still thin, and he still hopes to ensure a relatively good state.

"Xu Cang, the hydraulic pressure is gone. Be careful when you do manual braking later, don't tap the brakes." Mo Shangyun reminded from behind.

Although there is no hydraulic pressure, the brakes are theoretically useless.But in fact, due to the existence of the pressure storage bottle, it can still provide a limited number of manual braking pressure.

It was precisely because of the limit on the number of brakes that Mo Shangyun reminded Xu Cang not to tap the brakes, because this would quickly consume the pressure of the aircraft's storage tank.Continuous braking is the correct way to deal with it.

"I know." Xu Cang nodded.

He looked at the altimeter and it was already below [-] feet, and at this time the cockpit altitude light under the delay also went out.Xu Cang saw that it was almost done, and pointed to Tan Heling: "I'll take off the oxygen mask first, and hand over to the operator."

Tan Heling immediately took the plate with both hands: "Take control!"

Seeing that Tan Heling was ready, Xu Cang took off the oxygen mask with both hands, tidied his messy hair a little, put on the earphones again, switched back to the mask switch, and then said to Tan Heling: "Take control! Take it off!"

Xu Cang held the steering wheel with his left hand. When Tan Heling took off his oxygen mask, he made a passenger announcement: "The plane is about to return to Jianchuan and land in 5 minutes. You can take off your oxygen mask. Please fasten your seat belt."

After Xu Cang finished the passenger broadcast, Tan Heling just took off his oxygen mask, and his first sentence was: "Why did I feel that the pole was a bit heavy just now?"

At the same time that Tan Heling's voice fell, the main warning light of the aircraft came on, Xu Cang raised his head, and locked on the hydraulic panel all at once.Sure enough, the low-pressure lights of the engine-driven hydraulic pump and electric pump of the AB system all came on.

Tan Heling also noticed the fault lights on the hydraulic panel. He was not surprised. He had already found that the hydraulic pressure on the lower DU was dropping rapidly. It was expected that all four hydraulic low pressure lights would be on.

"Do you want to do the checklist of "Manual Recovery or Loss of Pressure in System A and System B"?" Tan Heling asked.

Xu Cang's expression froze: "Do it!"

Tan Heling looked at the DU page of the navigation, and the plane was almost on the fifth side at this time.According to the estimated landing time on the progress page of the CDU, the plane will land within 4 minutes, and the time is estimated to be too late.

"Not enough time!"

"Then do it according to memory!" Xu Cang put the throttle back to the slow car while speaking, and at the same time took the control wheel of the plane to maintain the plane's attitude, and said: "Check the altitude, the speed is good, and the flaps are one !"

Xu Cang still felt uncomfortable due to the excessive rod force under artificial recovery, and he felt more and more whether he should exercise more.

Tan Heling, who was standing next to him, saw that Xu Cang had started to release his flaps, and knew that Xu Cang really didn't intend to do any circling.However, Xu Cang is the backbone in the cockpit now, he doesn't want to hover around and wait, so let him do it.

Thinking of this, Tan Heling put the flap handle directly to the position of flap one.

At the same time, while controlling the plane, Xu Cang said, "System B is under no pressure, and the flaps will need to be manually lowered later. Let's do some preparatory work first."

Under normal circumstances, the hydraulic B system is used to release the flaps of the aircraft. At this moment, the hydraulic pressure of the B system has returned to zero. Even if Tan Heling puts the flap handle to the one position, the flaps will not change in fact. Yes, it is necessary to use an electric motor to release the flaps using the backup flap release method.

However, Xu Cang had to do some preparatory work before performing the standby flap deployment, that is, to manually restore some of the contents in the checklist.

As he spoke, Xu Cang raised his right hand, and said to the switches on the two black covers of the flight control panel above his head: "The AB system flight control switch spare rudder position!"

Tan Heling knew that Xu Cang was completing the manual recovery checklist based on memory, so he did not refer to the manual, and directly followed Xu Cang's instructions, stood up slightly, opened the AB system flight control switch cover, and dialed it to the spare rudder position.

Xu Cang didn't even raise his head to check Tan Heling's movements. The control of the plane really consumes too much energy for him now. In a literal sense, he has no time to take care of Tan Heling's movements.Moreover, considering Tan Heling's level, there should be no such low-level mistakes.

After hearing the sound of Tan Heling flipping the switch, Xu Cang didn't stop for a moment: "The switch of the yaw damper is switched on."

"The yaw damper switch is switched on." Tan Heling followed Xu Cang's instructions in this way, sitting one after another.

Normally, the yaw damper is on.However, after the hydraulic pressure of the AB system is too low, the switch may automatically trip and need to be re-connected manually.

"The hydraulic pump switches of system A and system B are all closed."

Under Xu Cang's instructions, Tan Heling turned off all the hydraulic pumps and electric pumps driven by the engine of the AB system, and then Xu Cang signaled Tan Heling: "Set the flap speed to [-]."

Under the condition of manual recovery, the landing configuration of the aircraft is not the conventional [-] flaps, but landing with [-] flaps. Tan Heling needs to reset the reference speed on the approach page of the CDU, because when he was preparing just now, he What is set is the reference speed of flap [-].

The new speed has just been set on Tan Heling's side, Xu Cang pointed to the panel at the bottom of Tan Heling's front: "Ground flap suppression switch, flap suppression."

When landing in a configuration other than flap [-], if the switch is not suppressed, the configuration warning will be recalled.It doesn't have any effect, but it will considerably affect the pilot's control. After all, a voice warning pops up suddenly, and the stress reaction is a little bit bigger, so it might be a go-around.

As soon as Tan Heling restrained himself, Xu Cang continued: "Our landing gear has been put down, so we don't need to manually put down the landing gear. We only need to put the flaps in reserve."

The retraction and retraction of the landing gear relies on the A hydraulic system. If the landing gear is to be released in this situation, some special means must be used, that is, manual extension of the landing gear.

However, in order to obtain a greater descent rate just now, Xu Cang had lowered the landing gear in advance, saving some steps.

"Okay, let's start to put the flaps in reserve now." Xu Cang pointed to a switch with a cover on the flight control panel: "The main switch of the spare flaps is set, and the switch of the spare flaps position is kept down." .We plan to put flaps [-] first, then set up the blind landing, and then put flaps [-]. Alright, let's go!"

Tan Heling himself was the captain, so Xu Cang understood it as soon as he said it.So, with a nod, the main switch cover of the spare flap was opened, toggled to the preset position, and then the switch of the spare flap position was continuously pressed.

Since the power for the backup flaps is only on a small electric motor, the release speed is very slow, and it takes a long time for the flaps to be put in the flap one position.

For some logical reason, the LETS will remain on until the flaps reach ten, even though no conditions exist that would cause the LETS to come on.

The theory of the three people in the cockpit is quite solid. After the flap indicator indicated that the flaps had reached the [-] position, they did not have to do the corresponding checklist because the transition light on the leading edge was on.

Xu Cang glanced at the flap indicator and continued: "Flap five!"

Tan Heling didn't say a word, and silently followed Xu Cang's instructions to release the flaps again.

At the same time, on the control tower of Jianchuan Airport, relying on binoculars, Director Liu can already visually observe the 9951N aircraft that is about to cut into the fifth side of the sky.

After watching for a while, Director Liu put down the binoculars, and his expression was relatively normal. Up to now, the crew has not reported any other problems.No report, that is the best news.

"It's okay, it's okay, it was a false alarm." Director Liu even showed a smile at the corner of his mouth.

After all, this kid Xu Cang encountered some world-class accidents at every turn, and the forced landing on the seaside of Qizhou some time ago was quite thrilling enough.In this way, it is thankful that some minor flight accidents happened to Xu Cang.

Throwing the binoculars to his assistant, Director Liu looked relaxed and scanned the situation on the apron below.In order to make enough space for Xu Cang to perform, Director Liu not only emptied the airspace, but also almost cleaned up the road surface of the airport.

There was no plane on the main taxiway adjacent to the runway, and one of the planes that was about to taxi out was stopped by the ground control, and the nose of the plane was facing the main taxiway A, and stopped in place.

According to the plan, the plane will land soon.After the plane landed, the field manager was doing a patrol to confirm that there was no problem with the road surface, and then it could take off.Therefore, the Muhua Aviation plane that stopped in front of the main taxiway A did not taxi back.

"Is the trailer ready?" Director Liu confirmed with his assistant again.

The assistant hurriedly said: "Get ready. As soon as the plane lands, we will arrange a tow truck to tow it away. The field service vehicle for the follow-up road surface inspection is also on standby. Everything is normal, and takeoff and landing can resume in 10 to 15 minutes." gone."

"Good!" Director Liu was very satisfied with his assistant's arrangement.At this time, when he turned his head, he could already see a small black dot in the sky on the final side of runway 05.It seemed that the plane was not far away from landing.

"It's such a good weather!" Maybe it was a sense of joy after the disaster. When he saw the emergency code on the 9951N before, his first thought was that it would not be another event of the level of the 747S2 switch.

However, in less than 10 minutes, the plane is about to land, so can you be unhappy?

Thinking of this, Director Liu couldn't help laughing and cursing: "Xu Cang gave me such a big gift before I left!"

At this time in the cockpit, the configuration of the aircraft has been prepared, and the aircraft has turned into the final glideslope.Xu Cang glanced at the cockpit panel at the end to confirm that there were no new problems, and then patted the thrust handle with his right hand: "Brother Tan, you can control the accelerator."

"Huh? What's the matter, is there a problem?" Tan Heling tensed up, and instinctively raised his head to scan the panel, thinking something happened.

Xu Cang shook his left hand: "Manual recovery is too strenuous, and I can't control one hand."

"Oh oh oh, this." Tan Heling suddenly realized and laughed, and hurriedly took over the thrust handle: "Okay, let me control the throttle."

After freeing his right hand, Xu Cang kept holding the plate with both hands, which was more comfortable now.Just relying on his left hand to operate, he felt his left wrist was a little sore and numb.

Seeing that everything is normal and the landing is imminent, Mo Shangyun even had the mood to tease: "Xu Cang, you have to go down to exercise, and you can't hold back."

"Yes!" Xu Cang also smiled wryly.

For a moment, the cockpit was filled with a cheerful atmosphere.

It's no wonder the three of them were slack, although Xu Cang complained that he was tired enough, but Xu Cang was really unambiguous in manipulating it.If it is not already known that the aircraft has lost all hydraulic pressure, it would not even feel that this is an artificially restored aircraft in terms of somatosensory.

As the altitude of the plane got lower and lower, Xu Cang's hand movements were still very steady.After falling below the decision altitude, Xu Cang turned to the visual stage, and he artificially asked Tan Heling to reduce the accelerator slightly, and in a relatively gentle state, the plane gradually dropped slightly below the normal glide path.

Under such an operation, when the plane enters the air above the runway, the PAPI will appear as three reds and one white, which is consistent with Xu Cang's previously estimated required approach height.

"Looks like we're lucky."

Seeing this, Xu Cang was still relaxed, and even had time to joke before landing.Under these words, the other two showed a knowing smile.

Xu Cang didn’t need to give instructions below the radio altimeter’s reading of [-] feet. Tan Heling began to slowly withdraw the throttle based on his own experience, while Xu Cang gently increased the aircraft’s attitude.

With a dull sound, the main wheels of the plane came down instantly and indirectly.Because of insufficient hydraulic pressure, Xu Cang did not arm the speedbrake, and did not plan to use reverse thrust.

Just as he was about to pull up the speedbrake manually, the plane that was taxiing normally suddenly began to tilt down to the left.

At first, Xu Cang was going to use the rudder to push the plane back to the center line of the runway, but out of the corner of his eye, he suddenly noticed that the red light of the left landing gear of the landing gear indicator light came on at some point.

The hairs on Xu Cang's whole body stood on end in an instant. He almost didn't think about it, and pushed all the throttle back just now to the front, and at the same time pressed the dial to the right, in order to prevent the plane from continuing to tilt to the left.

"Xu Cang, what are you doing?" Tan Heling was startled by Xu Cang's sudden re-acceleration.

Just now, he removed his left hand from the throttle lever after turning the throttle to idle.But it all fell to the ground, why did Xu Cang go crazy, and he had to put the accelerator to full.

"The left landing gear isn't put in place?" Mo Shangyun was sitting in the back and could see clearly, and reacted faster. After Xu Cang, he also noticed that the red light of the left landing gear was on.

"What?" After being reminded by Mo Shangyun, Tan Heling noticed that the red light on the left landing gear turned on, and he didn't notice it at all.

Since it is right in front of the field of vision, the red light will not cause the main warning light to turn on.

In this way, Tan Heling immediately understood.No wonder the plane suddenly turned to the left just now. It turned out to be the reason for the landing gear. He thought it was because Xu Cang didn't control the direction well.

Caught off guard, the plane had already veered a lot. If it slid down again, the plane would not be able to get back on the runway, and it would definitely run off the runway.Therefore, Xu Cang wanted to do another lap and make a prepared partial landing with the landing gear retracted.

Although it is difficult, the risk can be controlled after all with preparation.Moreover, it may be possible to deal with this fault in the time of another lap.

Fortunately, this situation happened very quickly, and Xu Cang's reaction was also very fast. He didn't pull up the speed brake or step on the brake, so the plane didn't slow down much.

Therefore, after Xu Cang stepped up the accelerator, the speed of the plane began to climb again under the roar of the two engines again.As the speed increased, the rudder effect of the aileron began to become obvious, and the tip of the large left wing that was about to touch the ground stopped the downward trend and became horizontal again.

"Xu Cang, enough speed, let's go!" Mo Shangyun shouted from behind.

As soon as Xu Cang heard that the speed was enough, he subconsciously pulled back the steering wheel with the force of a normal go-around.Xu Cang knew that the pitch of the steering wheel was limited, no matter how hard he tried, it would not be pulled back too much, so he didn't control his strength much.

However, after Xu Cang pulled the steering wheel that had been restricted in front, Xu Cang pulled it back a lot.

Fortunately, the speed of the plane has far exceeded the wheel rotation speed at this moment, and the plane immediately left the ground around the steering wheel.Otherwise, with Xu Cang's large amount of rods, the plane will definitely have to wipe the tail again.

"What's the matter, it's not stuck anymore?" Tan Heling's pupils shrank suddenly in such a reaction, couldn't the steering wheel only move back and forth within a small range, why was it pulled back so much by Xu Cang?
Mo Shangyun actually didn't understand why such a change occurred, but this may not be good news, at least the plane's pitch control is no longer restricted.

Moreover, even though Xu Cang's initial movement with the lever was rough and violent, from the physical point of view, it seems that the plane did not show any signs of rubbing the tail.

"It's okay, it's okay! Xu Cang, you didn't wipe the tail!" Mo Shangyun couldn't help but thankfully said.

However, Mo Shangyun quickly noticed Xu Cang's ashen complexion, his heart skipped a beat, and he immediately realized something was wrong: "Xu Cang, what's wrong?"

I saw Xu Cang struggling to push the steering wheel, and shouted at the same time: "No! It's stuck!"

Tan Heling was shocked all over, he also held the steering wheel with both hands, and exerted force suddenly.However, the steering wheel, which was still slightly moving just now, really took root again at this moment, and under the control of the two, it did not move at all.

"Stuck, really stuck!"

Tan Heling's breath was almost held at this moment, his mind was blank, and he yelled: "How could this happen?"

The timing of this pitch jam was bad, bad, deadly!At this moment, the control wheel of the plane is just stuck in the place where Xu Cang took it a lot of distance, so that the plane always maintains the pitching attitude of taking off and climbing.

This attitude is too big, too big for all phases of flight except liftoff!But at this moment, the pitch trim of the plane has been pushed forward to the maximum, and they no longer have the means to suppress the nose-up.

Sure enough, under an extremely exaggerated attitude, even under almost full thrust, the aircraft's rate of ascent is indeed like a wild horse, straight into the sky, but the price of all this is the crazy descent speed.

In less than ten seconds, the speed of the plane began to drop rapidly after experiencing the initial surge, and it entered the warning zone in an instant.

Xu Cang frantically pushed the steering wheel forward, but the steering wheel didn't move at all like an unstoppable breath of death.At this moment, even Tan Heling realized the seriousness of the problem, and his thoughts seemed to be frozen in this moment.

"There is no other way!" In his mind, Tan Heling just came to this conclusion, but out of his biological survival instinct, he was still pushing the steering wheel hard, trying to gain the last chance of life.

But the overwhelming death pressure made him almost unable to breathe.Suddenly, the steering wheel he was holding began to vibrate crazily, and it was transmitted to Tan Heling's wrist and heart, which seemed to arouse his will to give up.

"Xu Cang! Help me!"

Tan Heling has never had such a strong idea at this moment.

However, amidst his roar and the shocking sound of the stall shaker, under the action of turbulent flow, the lift force that the aircraft's wing surface can produce in a deep stall is getting smaller and smaller.

Finally at that moment, the plane stopped going up.From the perspective of others, the plane is slowly hovering in the air with a gesture of piercing the sky.This tens of tons behemoth lost its last bit of lift, and the next moment, it was about to fall straight down like a free fall.

On the tower, Director Liu witnessed this death-like scene with his own eyes. He let out a breath, but there was endless fear in the sound of his breathing. He had already seen the arrival of death.

"Ruined!"

Everyone, everyone has already smelled the breath of death, and even the eyes of the god of death have been watching this plane at this moment.However, at this moment, Xu Cang's eyes burst out with unprecedented light.

He is not afraid of death, because death should be afraid of him!
He just wants to change his fate against the sky in this mortal situation!
