In an instant, after the L-15C Falcon Higher Education fell to a height of about 700 to 800 meters, as the fuselage dive accelerated, the high-speed airflow passed through the surface of the wing, and the left and right wings resumed a certain degree of pressure difference, and the body transformed from an out-of-control state to a semi-out-of-control state, and the rotation state slowed down.

After another second, as the speed increases to 200 per hour, the airflow returns to the regularity, the aileron system and the rudder restore aerodynamic performance, the body returns to a controllable state, and the rotation state is eliminated.

"Buzz!"

The engine whistles spread throughout the sky. Yang Xiaolong gently pulled the rod, stepped on the rudder with his right foot, and flew out a graceful and elegant arc to restore his horizontal posture.

"What do you feel?" Yang Xiaolong asked, waiting for the body to return to normal, his tight strings relaxed and asked.

Even many old pilots were a little scared when the stalled tail spin, even Yang Xiaolong was no exception.

This subject is the real meaning of contact with the edge of death.

In less than ten seconds, from entering the stall tail spin to changing out, the L-15C Falcon fell from 14,000 meters to 12,980 meters.

Zhou Hai's voice was the same, without any change, and he was relaxed and calm: "Fortunately, as long as you keep calm and deal with it correctly, you can change the stall tail spin at a high probability."

"Don't forget, there is also altitude! The stall tail spin may have any height, from 10,000 to 5,000 meters, the head downward change rate is 90%, and the tail downward change rate is 40%.

Yang Xiaolong took a deep breath, spoke seriously and seriously, warning: "One thousand meters to five thousand meters, the two are 40% to 10%, and below 1,000 meters, the change rate is only 1%. If there are no people or cities on the ground, parachute jumps immediately and you must not hesitate. We are not afraid of falling planes, but we are afraid of saving my life."

high!

This is the most important basis for changing the stall tail spin. If the stall tail spin enters one thousand meters, the reaction time is only ten seconds, and the machine head faces downward has a 1% change rate. It is almost impossible to change the stall tail spin. It must be ejected immediately and escape.

"Okay." After hearing these words, Zhou Hai nodded and responded.

Yang Xiaolong took a deep breath and arranged: "The control is given to you. The stall angle of attack limit has been lifted. We will conduct head-down modification training. For safety reasons, we will climb back to 14,000 meters. Remember what I said - stay calm."

After the words, the control of the body was handed over to Zhou Hai.

Holding the joystick again, Zhou Hai breathed out a breath, clearing the slightest tension that surged out of his heart. His eyes were bright and his spirit was highly concentrated. He raised his head to the lever and maintained a normal climbing posture.

When the entire L-15C falcon returns to a height of 14,000 meters in a slow posture, the speed is reduced to 350 kilometers, and the silver-gray round nose is raised high, like an eagle looking down on the world, with its fuselage horizontally tilted to the left.

"drop!"

In less than a second, an extremely rapid prompt sound rang in the cockpit, and the left wing tip edge bar first entered the stall state, creating a domino effect, which quickly affected the ailerons and flaps.

The left wing stalled, the fuselage lost balance, and Zhou Hai pressed the pole with the momentum, causing the head to tilt down to the left, and the entire L-15C Falcon re-entered the deadly and dangerous stall tail spin flight state.

Rotate!

Rotate at a frequency of two turns per second, and the rotation speed is still increasing.

The speed is 50 kilometers per hour and the drop rate is 103 meters per second.

Standing on the seat, Zhou Hai's eyes easily captured the high-speed rotational image, and his dexterous and powerful hands carried out a series of operations. The throttle valve was reset and returned to zero. The pressure rod kept the head facing downward, and the right foot was full of the rudder.

Calm and fast.

The round and sharp nose is aimed at the vast land below, and the body in an out-of-control state shows a free fall motion manifested by physical laws.

One second, two seconds, three seconds!

The dive speed increases rapidly from slow to fast, thin air blows and sweeps the middle single wing, the flap aile system regains aerodynamic performance, the rudder follows and recovers, and the rotation is rapidly slowed down.

Seeing that the body was restored to a controllable state, Zhou Hai did not hesitate and changed the lever smoothly, pushed the throttle upward, and supplied oil to obtain power.

"boom!"

The L-15C falcon, which was experiencing the edge of life and death, flew out in a flat manner, accompanied by the roar of the engine, making a hissing sound like an eagle. The tail nozzle dragged out two slender white tail clouds, all showing an elegant and proud posture.

"Very good, Zhou Hai, you are indeed a good piece of material." After the fuselage was leveled and flew out, a bright smile appeared on Yang Xiaolong's face, and he was not stingy with his praise.

excellent!

To be honest, Yang Xiaolong never expected that Zhou Hai would successfully change the subject at a high altitude stall and the tail spin was released. The whole process was standard, without any rustration or pause, and was as calm as an old pilot.

Panic and blind operation, the performance these flight students should have never appeared in Zhou Hai at all.

"No, I was a little nervous just now." Zhou Hai smiled when he heard Yang Xiaolong's praise, and the nervousness in his heart disappeared and he returned to peace.

Calmness?

That was pretending, saying that you are not afraid is simply a fool. You know, this is a famous high-altitude stall tail spin.

Fortunately, it was successful and Zhou Hai accumulated valuable experience.

"Nervousness is nothing, just deal with it stably. Every time I do a high-altitude tail spin, I am also nervous. Today I perform very well." Yang Xiaolong smiled, and his words showed a hint of fatigue: "Okay, let's finish training today, let's go back."

"Teacher Yang, don't you practice the level and the tail of the machine?" Zhou Hai said in confusion when he heard this.

"Practice the level and tail of the machine again later. You have to eat the meal one by one. By the way, Deputy Lei, arrange a new task and learn how to drive with the ground crew leader later." Yang Xiaolong exhaled and replied.

"Learn to drive?" After hearing Yang Xiaolong's words, Zhou Hai was puzzled: "Well, aren't we prohibiting driving?"

In daily life, flight attendants and pilots are prohibited from driving, which is a separate discipline.

"It's right to prohibit driving, but you have to master the driving skills and know how to drive. You won't be fooled in emergencies." Yang Xiaolong said with a smile: "I forgot to say that you have to learn bicycles, motorcycles and cars, and you must go through an assessment, but you don't have a driver's license and you'll be back."

"Okay." Zhou Hai responded with a helplessness, subconsciously pulled the rod and stepped on the rudder, and easily controlled the fighter plane and turned around and returned.

Learn to drive?

For Zhou Hai, who has been flying, it is a new thing. Although this situation of learning how to drive but not issuing a driver's license is a bit pitfall.

Yang Xiaolong is right. Flying officers are indeed strictly prohibited from driving, but you must master this skill and not be fooled by war and other emergencies.

Considering this situation, it doesn’t seem to have any impact on whether or not you have a driver’s license.
