The temperature of the EGT is still fluctuating, but it has been in the position of exceeding the limit, and it has not fallen.

At the same time, Xu Qing may clearly hear that the sound of the engine is abnormal, and it has changed from a continuous whistling sound to an intermittent subwoofer-like rumble, which is very scary, which is almost certain that the engine is surging!

But why did the engine suddenly surge, it doesn't make sense!

Before Xu Qing could figure out the reason for the engine surge, another sudden downdraft hit the fuselage, and the plane, which had already deviated from the altitude by more than two hundred feet, fell another hundred feet almost instantly.

This large bow made the upper body of the instructor, who was already unconscious, crash into the visor again. Xu Qing's eyes were quick, and his left hand grabbing the accelerator grabbed the instructor's right shoulder like lightning, so that he could stop the instructor's secondary injury!

But in order to fix the instructor, Xu Qing's range of movements was too large, and his right hand unconsciously pressed the steering wheel, causing the plane that was already in a state of bowing his head to rush down a few points.

For a while, Xu Qing was embarrassed, and the situation was extremely critical!

"Wang Jiya! Are you TM dead? But come and help? Xu Qing, who was in a dilemma, suddenly let out a loud shout, almost suppressing all the noise in the cockpit, and shaking Wang Wanya's brain buzzing.

It was with this sound that Wang Wanya broke free from his great fear.

Wang Jianya waited for the plane to stabilize a little, quickly unbuckled his seat belt, and immediately got up and grabbed the seat in the left seat with one hand, and helped Xu Qing fix the instructor with the other.

With Wang Jianya's help, Xu Qing instantly freed up his hand to control the plane.

Fortunately, after encountering a downdraft, the plane ushered in a brief period of calm. It was at this time that Wang Jianya quickly fastened the shoulder strap for the instructor, then retracted his position and re-fastened his seat belt.

Wave after wave of turbulence hit the plane, making the plane in an almost out of control state, and Xu Qing could only maintain the state of the plane with all his strength.

No matter what causes the aircraft engine to surge, there is no time to delve into it, and the top priority is to do the memory project of engine surge, otherwise the engine will be seriously damaged!

"Autothrottle, disconnect!"

"Thrust handle, one shot retracted!"

At this time, the left seat was no longer able to cooperate with him, and Xu Qing still recited and made movements by himself.

In the case of slowly retracting the thrust handle of a shot, the EGT has no downward trend at all, Xu Qing's heart is cold, this engine is wasted!

"Blue 9441, keep altitude 8100, you're 300 feet off altitude now!" At this time, the control noticed the strangeness of Xu Qing's plane and began to warn them.

Xu Qing was just about to answer, when a different upward impulse hit the plane violently, and Xu Qing couldn't suppress the upward force.

This sudden rise made Xu Qing's body press the back of the chair, and the hand that was still slowly closing the accelerator was pulled back, directly to the slow parking space.

The huge difference in thrust between the two sides caused the aircraft to slip significantly, and the nose of the aircraft immediately veered to the left.

Due to the tremendous increase in attitude and the rapid loss of engine power, the speed of the plane dropped like a racing car without brakes, from 280 knots to 210 knots in the blink of an eye.

And the momentum is unabated, breaking through the UP speed all the way, alerting the yellow zone and going straight to the red zone.

Xu Qing focused almost all of his energy on controlling the attitude of the plane, not taking into account the change in speed. When Wang Jianya reminded him behind him, he was greeted by a rapid sound of shaking rods.

At the same time, the aftermath of the uprush has disappeared. Xu Qing seized the opportunity, pressed the steering wheel, reduced the attitude of the aircraft, and at the same time increased the second throttle, kicked the right rudder, and eliminated the sideslip of the aircraft. He didn't dare to add another shot of the throttle now, but the red EGT indication still showed the seriousness of the matter.

"Blue 9441, what is your current situation, can't you maintain your height?" The control side found that Xu Qing's height went straight up and down in a short period of time, which was extremely weird, and guessed if there was something urgent.

At this time, the plane was slightly stable, and Xu Qing hurriedly replied to the control: "Blue 9441, now the captain is in a coma, and he is in a hurry, and there is serious icing and intermittent violent turbulence at this altitude. ”

When there was severe freezing, Xu Qing's eyes lit up in a flash, and they froze! It's a surge caused by icing!

The high vibration value of the engine just now is also caused by icing, and he remembers that this principle was mentioned in the previous notice issued by the company. However, it was only the high vibration value of the engine, which was not as serious as Xu Qing and them, and it turned into engine surge.

The control guessed that there might be something wrong with 9441, but he didn't expect the problem to be so serious, and hurriedly asked: "Blue 9441, are you declaring a state of emergency now?" ”

Xu Qing didn't hesitate: "That's right, I immediately asked to change the altitude, we highly suspect that the engine failure is related to icing, and we need to get out of the icing area quickly." ”

"9441, can you accept altitude 9500 now?" The regulator asked.

Xu Qing almost scolded, how could the plane be able to climb so high now that it was in a single-engine state.

"We're single-shot now, we can't climb that high, can't we descend?"

"No, you can't go down the shelling area!" The controller immediately rejected Xu Qing's idea.

Xu Qing was anxious, if he continued to fly like this now, what if the second shot also suffered a problem with the first shot. Some time ago, the simulator inspection gave him a double-engine failure, is it possible that the plane really has a double-engine failure, and the gliding landing fails?

Xu Qing glanced at the weather radar, and he found that if he deviated to the right, he could breathe out as soon as possible, and there might be no ice at that time.

"Then can you look right?" Xu Qing applied again.

"On the right, there's military activity on the right...... Wait a minute, I'll coordinate it! ”

Xu Qing controlled the plane to slowly rise to 8100, and at this time, the airflow stabilized a little, and he took on autopilot.

At this time, Xu Qing found that his body was soaked in cold sweat, as if he had just been fished out of the water.

With a sigh of relief, Xu Qing handed the quick checklist to Wang Qianya and asked him to continue to do it.

Now the airflow is not completely stable, and it is not easy to move the instructor out, and when the control side is restored, you can turn right to vent the air, everything is stable, and then move the instructor out of the cockpit.

It was very turbulent just now, and I don't know if anyone was injured in the cabin, so I will make a checklist in a while and ask about it.

Wang Jianya took the quick checklist, and just turned to the engine chapter, suddenly his nose sniffed, and he was extremely puzzled: "Xu Qing, do you smell anything?" ”

Xu Qing didn't know why, but also sniffed carefully, there was some strange smell.

Suddenly, the faces of the two changed wildly.

This is...... Burnt taste!
