Chapter 24 Absolute Body Sensation
The captain only felt a tingling sensation transmitted from the back to his scalp. He stopped reminding Xu Cang and instead grabbed the steering wheel with his left hand. He had to do something!
At the same time, the captain's right hand pretended to grab the throttle lever of the No. 1 engine. He was trying to regain control of the aircraft.
However, at this moment, Xu Cang grabbed the captain's wrist with his left hand, urgently and forcefully. Xu Cang's expression did not change at all, and his voice was cold and unquestionable: "Don't move, the plane has not stalled yet."
The captain was stunned for a moment, but quickly understood what Xu Cang said.
Stick shake is not a sign of stall, but a sign of impending stall. Stall is an extremely dangerous phenomenon in any aircraft, especially in the field of civil aviation where safety is important. This situation must be avoided. Therefore, Boeing will not give an alarm until the aircraft enters a stall, but will give a warning before entering the stall, that is, stick shake.
The stick shaker of the aircraft provides 1.3 times the stall speed margin. For example, the aircraft will stall at 100 knots, but in fact, the aircraft will start to shake the stick at 130 knots. This means that even in the stick shaker range of 100 to 130 knots, the aircraft has not actually entered a stall.
"You are playing with fire!" The captain still could not accept this kind of dancing on the edge of a knife, because there was no clear indication from stick shaking to actual stall, and the crew could not judge what was already stalled and what was about to speed up!
"Five knots. I will maintain the speed at five knots less than the stick shaking speed, not a knot more." Xu Cang shook the captain's right hand off the throttle lever of the No. 1 engine.
At this moment, although the throttle lever of the No. 1 engine has not moved, the actual thrust has been reduced to more than 40 N1, which is close to the idle thrust, which also means that the aircraft is almost out of power.
It was in such an embarrassing situation that Xu Cang had to make some dangerous moves. Often there was no way to have the best of both worlds, but something had to be done.
The captain gritted his teeth and said, "In this kind of wind, you can't maintain a stable speed."
Without power, the plane is completely gliding, which is literally "drifting in the wind". Even with the power of one engine just now, it was unable to maintain the state of the plane, let alone now.
The stick shaker speed was five knots. If Xu Cang could maintain this speed accurately, the captain could barely accept it. The problem was that he felt Xu Cang could not maintain it.
As if to confirm what the captain said, a sudden turbulence briefly reduced the aircraft's descent rate to zero, but the speed was about to decrease. However, Xu Cang pressed the control wheel just before the speed changed, and the number on the aircraft's airspeed indicator only moved slightly , without even a knot change.
This was not the end. While suppressing the speed change, Xu Cang suddenly pressed the wheel back to the right. But in the captain's opinion, the plane did not receive any information about increasing the slope, so why reduce the slope?
At the moment when the captain formed this thought, the plane was suddenly affected by the airflow, and the bank increased to the left without any warning. However, Xu Cang had already made corrections before, and the moment the airflow affected the plane, a counteracting effect was formed. The plane's bank increased to 35 degrees in the blink of an eye, and it lasted so long that the plane did not issue a bank warning.
The cockpit was dead silent, the only sound that could be heard was the captain's heavy breathing as his chest rose and fell rapidly.
Too fast. Xu Cang's correction was too fast. Before the deviation appeared, he already knew how the deviation would occur, so he could react in advance and eliminate the deviation within the smallest impact range.
Even though the Boeing 737 has some weaknesses compared to the Airbus 320, a real pilot will still prefer the 737. Because on the 737, the pilot can feel the stick force, and then can perceive the operation of the control surface and the changes in the state of the aircraft.
A top pilot can become one with the aircraft through stick force!
Perhaps, this state of human-machine integration will take ten, twenty years, or even a lifetime to achieve, but now the captain seems to have seen it.
As easy as commanding an arm, doing whatever you want!
“Is this the absolute physical sensation?”
The captain almost let out a long howl at this moment. His master once said that some people are born with a gift from God, and the starting point of their birth is the end point for others.
Those people don't care about airspeed, attitude, throttle, wind direction and speed, sideslip, touchdown point, and leveling techniques.
They fly the plane based on their feelings and...instincts. They want the plane to appear in whatever state it wants.
This is the difference between people! This is the absolute physical feeling!
The captain had no doubt that even if Xu Cang's eyes were blindfolded at this moment, he would still be able to discern the deviation in the aircraft's status and correct it as quickly as possible.
In such a windy environment, many pilots could not ensure the stability of the aircraft's airspeed even when the two engines were operating normally, not to mention that Xu Cang had to control the descent, slope and sideslip of the aircraft at this moment.
"There is such a person in Blue Sky Airlines!"
The captain was speechless. This move alone crushed him to the point of being useless. He had no room for rebuttal. The pilot's circle was very dirty and pure. At this time, the title of captain was meaningless.
Xu Cang didn't care how much his control had shocked others. He just felt that the control wheel of the plane was becoming heavier, so that he had to start releasing the stick very slowly to maintain the stability of the plane's speed.
This was because engine number one was failing and the speed could not be reduced any further.
As the plane continued to turn, they could already see the terminal building of Jianchuan Airport. After turning for a while, the plane would be aligned with the runway.
It seems that victory is in sight!
"We are about to touch down outside the runway!" Xu Cang suddenly said this.
The captain was startled: "What did you say?"
The moment the captain finished speaking, a harsh friction sound like rusty gears pressing against each other came from outside the left side of the plane, followed by a dull rumble, as if something exploded in an iron barrel.
Amid the tremors of the aircraft, everything finally calmed down, the N1 speed of the No. 1 engine directly returned to zero, and even the wind speed did not exist.
At this moment, Xu Cang withdrew his left foot from the rudder pedal and sighed: "You can put out the fire!"
