Return to 2000: Captain of the Great Powers

Chapter 23 The tip of the knife dances and turns while stalling!

The captain was in a state of extreme mental tension since the take-off and run of the engine. It is understandable to react to some problems, such as overreacting to execute the memory items of the engine fire serious damage or separation checklist.

Xu Cang's actions undoubtedly awakened the captain, the captain was simply tired, not because of his own strength.Almost instantly, the captain realized his mistake, and immediately withdrew his right hand placed on the thrust handle of the No. [-] engine.

He lightly pulled the starter switch of the APU, and at the same time looked back through the side window on his left, but he didn't see the runway of Jianchuan Airport.Because the runway was right behind the plane at this time, and it was already at the dead end of the field of vision, but what really puzzled the captain was the turning direction that Xu Cang said he chose.

"Why don't you turn right?" The captain's mind became clearer at the moment.

"The sideslip and the wind will make us farther and farther away, and we will not be able to turn back." Xu Cang's answer was quite short.

At this moment, the steady crosswind is blowing the aircraft from left to right, and even though the thrust of the No. 180 engine is constantly decreasing, it means that the sideslip of the aircraft is constantly decreasing, but it does not mean that there is no sideslip.As long as the sideslip exists, the aircraft will have a tendency to drift to the right.At this moment, if the plane chooses to turn right under the influence of two positive feedback factors, when the crew turns [-] degrees, they will find that the plane has deviated to the left side of the runway by a considerable distance.

When there is motivation, this may not be a headache enough, but when there is no motivation, this is an extremely troublesome trouble.

The No. [-] engine has its last stubbornness, and it is still running with difficulty in the flames, but Xu Cang's mind is very clear, this is just the engine's reflection.

"But to the left, can we turn around?" The captain expressed concern about this.

Xu Cang's face remained unchanged: "If you can't turn around, then increase the slope!"

"But on a big slope, the height will drop very quickly, and you won't be able to support the field."

"Then you should pray that engine number one will burn a little longer."

The communication between Xu Cang and the captain was extremely brief, but it was like an ordinary chat between ordinary people.It's just that at the end, the captain obviously couldn't hold back, and he felt like gnashing his teeth every time he said a word.

It could be heard that the captain couldn't help getting nervous, especially after finding that the plane couldn't turn around at all.

Both the wind and the residual thrust of the number one engine were preventing the aircraft from turning left, which was what the captain had feared.Xu Cang was relatively conservative at the beginning, only using a slope of about [-] degrees.This is not an overly conservative slope for a single-engine aircraft with flaps lowered, but it obviously cannot cope with the current situation.

Although the turning slope is formed, the change of heading is extremely slow.If this situation continues, the plane may not be able to turn around until it flies over the runway.

The captain said anxiously: "The wind is too strong, and the turning slope is restricted in the single-engine state, so it is impossible to turn around."

"If you can't turn around, it can only mean that the slope is not big enough. What kind of slope limit? I can't take care of these at this time!" After finishing speaking, Xu Cang directly ignored the limit of the turning slope due to lack of power, and directly increased the slope to 35%. Between thirty and thirty-five degrees.

"Notify the cabin to make an emergency landing immediately, and prepare for collision prevention." The sweat on Xu Cang's forehead dripped down from the brows, slid across his cheeks, and moistened his lips.Xu Cang pursed his lips, he could feel his heart beating wildly, and a huge amount of fresh blood was sent to his limbs and bones, which he urgently needed now.

"If possible, announce MAYDAY, apply to control to evacuate in place, and request ground support."

Previously, Feiyu 6321 declared the PANPAN state, which is a secondary state of emergency compared to MAYDAY.But now it is obviously beyond the definition of PANPAN, and the state of emergency needs to be declared again, that is, MAYDAY.

The situation was urgent just now, Xu Cang only reported his intentions, but did not update the emergency status, now he needs the captain to help him finish all this, and the request to evacuate in place after landing must also be reported.

The captain didn't hesitate, Xu Cang was ready to notify the cabin crew as soon as he opened his mouth.But as soon as this eye saw the PFD display, a cold sweat broke out.

At this moment, the airspeed of the plane is just above the top of the red and black speed band with the minimum speed, and the pitch limit indicator shaped like a small eyebrow is tightly attached to the attitude indicator of the plane.

Although the number one engine had some residual power, it was not at all sufficient to provide the additional downward tendency the aircraft produced when turning.Why is it impossible to return to the voyage when the twin engines lose thrust after takeoff? The problem lies in the turning?
Once the aircraft turns, the lift generated will be broken down, which means that the aircraft will lose altitude faster.The altitude of [-] feet is already too much for straight twin-engine gliding, let alone the plane is still turning?

The power of the No. [-] engine is unable to support the aircraft to turn while maintaining sufficient maneuvering speed.This has nothing to do with the control ability of the crew, it is determined by the purest laws of physics, and no one can change it.

Therefore, Xu Cang had to choose between high speed and speed.Obviously, Xu Cang felt that altitude was more important, so he decided to release some kinetic energy, that is, to hold the steering wheel a little bit to stop the falling momentum of the plane.

But without enough motivation, this action is a standard deceleration behavior.Thus, shortly after the bank of more than [-] degrees was established, the speed of the aircraft dropped from flap one maneuvering speed to near stick shaker speed.

Since the plane formed a bank of more than 05 degrees, the direction change of the plane began to become obvious.And Xu Cang calculated based on the heading of runway [-] that they still need to maintain this slope for a while.

However, the plane has begun to fail!The altitude of the plane is still in danger, Xu Cang can't let go of the steering wheel yet, he must keep it on, which means that the speed is still faster than the one that was sacrificed.

"It's about to stall, it's about to stall!" The captain saw that Xu Cang hadn't released the stick yet, but was still holding the stick, so his voice was sharp: "Release quickly!"

The captain's body hairs stood on end. At this time, the plane was not only turning, but also slipping slightly.

What is a stall with sideslip?That's a tail spin!As long as a gust of wind blows, the plane will roll over without control, without any life.

However, the captain's reminder did not stop Xu Cang's operation at all.He was actually still wearing the steering wheel, the speed of the plane immediately broke through the red and black speed bands, and the attitude indicator also passed the pitch limit indicator. At the same time, the signal from the stall management computer ordered the two steering wheels to start shaking.

The plane is shaking!
