Return to 2000: Captain of the Great Powers

Chapter 20 Vitality after three years
The radio altitude is 6321 feet, the radio altimeter is in effect, and the tower gives the landing permission: "Flying feather 16013, surface wind 16, gust 23 meters, runway [-] can land, pay attention to the final airflow."

"Runway 23 can land, Feiyu 6321." Xu Cang replied to the control tower, then held the steering wheel, but did not use force, and at the same time stepped on the rudder pedal.He could feel that the captain was constantly adjusting the input rudder of the rudder, and the movement range was particularly large.

"The landing command is here." Xu Cang's eyes fell on the upper left corner of the navigation page, where there is real-time wind in the air.

Although the five-sided airflow of Jianchuan Airport is better than that of Erhai Airport, it is also a tricky level for domestic airports. In addition, in the case of a single engine, the aircraft's ability to resist crosswinds and anti-gusts is significantly reduced. The ups and downs of a lone boat in a raging sea are quite thrilling.

The turbulence continuously impacted the vertical tail, which in turn affected the crew's influence on the sideslip of the aircraft.In the case of normal twin engines, the yaw damper will help eliminate sideslip, so most of the pilots will not control the rudder in the air.However, the emergence of a single engine directly broke the balance ability of the yaw damper.

In fact, if the crosswind of 160 degrees at Jianchuan Airport is stable, the vertical tail will make the nose of the aircraft turn to the left.This crosswind effect somewhat counteracts the natural nose right turn caused by inconsistent thrust.

However, the five-sided airflow at Jianchuan Airport is not stable.Sometimes the sudden strong right-hand wind will not only aggravate the sideslip of the aircraft, but even stepping on the full rudder cannot stop the sideslip of the aircraft.

The most dangerous thing at this time is to fully step on the left rudder, but under the influence of airflow, the aircraft needs the left pressure plate to maintain the aircraft on the localizer.

The normal operation is left rudder and right turn, and left rudder and left turn is very easy to turn the aircraft over.

The captain tried to switch on the autopilot during the descent, but under the action of turbulence, the autopilot could not maintain the normal approach attitude at all.In the absence of any other means, the captain could only manually fly the plane.

However, the complexity of the aircraft state far exceeded his expectations.Even if there is guidance to guide the attitude of the aircraft, the autothrottle cannot be turned on.In some extreme cases, the captain even had to increase the throttle of the number one engine to create a larger thrust difference to offset the effect of the right wind.

However, once the throttle is moved, it will cause a chain reaction of airspeed.Originally, in the single-engine landing configuration, the speed zone area was restricted.The turbulence itself will also cause drastic changes in speed, and when the throttle is closed, the captain has already started to panic at an altitude of [-] feet.

"One thousand feet, the landing form is complete!" Xu Cang turned on all the external lights and sent a signal to the cabin that he was about to land.At the side, Xu Cang was terrified to see the captain's operation, so he asked, "Do you want me to come?"

However, the captain just controlled the plane with his head sullen, and didn't respond to Xu Cang for a long time.It's not that he didn't hear Xu Cang's words, but that he had spent all his energy on manipulation, and he couldn't spare any energy to communicate with Xu Cang.

This is obviously a critical point, and the captain can't stand it anymore!

To be honest, the wind at Jianchuan Airport is very strange today.Generally speaking, when coming down from a high place, the wind speed will be slightly reduced under the action of ground friction.In this way, in the low-altitude environment, the difficulty of maneuvering will be reduced.

But for some reason, as the altitude of the plane decreased, the intensity of the turbulence became stronger and stronger, so that the captain was so exhausted that he had no time to care about him.

Not long after the plane passed the altitude of [-] feet, the plane suddenly lowered its head fiercely, and the speed of the plane jumped up like a rocket.

These changes startled the captain, and instinctively followed the guidance to press down on the plate in order to keep up with the guidance.However, the pressure plate was so severe that the aircraft's descent rate suddenly increased from [-] to [-] feet.

Although the concept of a stable approach is not taken so seriously in this era, it is absolutely abnormal to have a large descent rate of [-] feet per minute at a low altitude environment below [-] feet.

Xu Cang just wanted to remind, but the co-pilot sitting behind couldn't help it, and suddenly shouted: "Descent rate!"

But the problem the captain faced was not just the excessive descent rate, but the uncooperative retraction of the throttle while he was holding the disc.During final approach, it is necessary to cooperate with the throttle reduction when pressing down on the plate. This should be a common-sense operation, but when it fell on the captain, such a low-level mistake occurred.

He has reached his limit, and the huge pressure has begun to affect the captain's basic control ability.Even the co-pilot, who was well aware of the situation at the moment, was overly nervous, and his field of vision began to become paranoid and narrow.

The co-pilot discovered the problem of the excessive descent rate at the first time, but he ignored the soaring airspeed.At this time, the speed of the aircraft is very close to the speed band of the maximum speed.

"They're all dead!" Xu Cang thought to himself.

There is only one person in this cockpit who is still calm, and that is Xu Cang.He didn't even remind the captain of the speed problem, because he knew that due to the overloaded state of the captain, the captain would not be able to respond in time to his reminder.

Although there were some violations, Xu Cang decided to intervene in the captain's manipulation at this time.Without informing the captain of his intentions, Xu Cang patted the back of the captain's right hand with his left hand, and even the thrust handle of the No. [-] engine also patted the idle thrust.At the same time, Xu Cang yelled loudly: "Get out!"

It can only be said that the captain is still the captain, even in this almost overloaded state.Without any reminder from Xu Cang, Xu Cang's intention was reflected by the action of Xu Cang forcibly closing the throttle.

As the No. [-] throttle is turned off, the thrust difference between the two wings almost disappears, and the rudder must be reduced accordingly, otherwise the aircraft will form a new sideslip.

Under Xu Cang's shout, the captain retracted his left foot like lightning.Then, he flicked up the steering wheel slightly, and the aircraft's descent rate instantly decreased. At the same time, he added the throttle of the No. [-] engine, and the matching rudder volume also followed.

Xu Cang's grip on the steering wheel was getting stronger and stronger, and he was waiting for the captain to hand over the controls at any time.In fact, according to Xu Cang's understanding, it is better to let him fly from now on, but he knows that this is impossible, and it involves the pride of a captain, so he has to try it once.

When the plane was at an altitude of [-] feet, Xu Cang could already clearly see the buildings near the airport.Suddenly, he stumbled upon an office building with a white outer wall.

This kind of building is very common in the airport office area, but it attracted Xu Cang's attention in just one click.Because there is a huge logo on the central roof of this office building. It is a huge green leaf, which is exactly the same as the logo on the packaging of the third-generation immunosuppressant developed three years later.
