Under normal circumstances, the vast majority of aircraft with poor flight performance, such as bombers, ordinary civil airliners, transport aircraft, etc., are strictly forbidden to enter the stall tailspin state.

Once entered, there is only one result - the plane is destroyed and people are killed.

It's dangerous!

However, every fighter plane's high-level pilot trainee must deliberately let the aircraft enter a state of stall tailspin and learn training and change skills.

"Check the plane." Yang Xiaolong heard about it and gave an order.

Without hesitation, Zhou Hai, who was full of anticipation in his heart, turned to meet the L-15C Falcon waiting quietly on the tarmac.

Zhou Haide admits that he has completely fallen in love with this high-level education aircraft with an excellent flying experience.

Under the gaze of a group of ground staff and Yang Xiaolong, Zhou Hai carefully checked around the fuselage, confirmed that it was correct, returned to the front of the tarmac, raised his hand and reported: "Report to Comrade Instructor, the plane has been inspected, everything is normal." ”

Yang Xiaolong nodded when he heard this, carefully reviewed the fuselage, signed the plane receipt document in the hands of the ground crew leader, and issued the boarding order.

The two climbed the boarding ladder one after another and entered the cockpit, Zhou Hai carried out a series of operations with both hands, the drop-shaped glass cockpit cover slowly closed, and the ground crew quickly got busy.

"Boom!"

Tens of seconds later, the roar of the engine echoed all around.

The two turbofan engines on the left and right sides of the fuselage are running smoothly and normally, and the tail nozzle spews out high-temperature airflow, heating the small raindrops that flutter behind the evaporation shed, producing a rather spectacular white mist.

A ground crew member held two yellow and red eye-catching flags, signaling that it was ready to slide out, and the L-15C Falcon with a sci-fi atmosphere on the fuselage was fully fueled, slowly slid out of the shelter apron, turned to the right and drove into the continuous drizzle, and drove smoothly along the apron area passage.

Thanks to the sleek shape of the canopy and the transparent rainproof coating on the surface, it is easy to block the small raindrops flying all over the sky.

The wind was a little strong, and there was a chill, which was caused by the sudden cold air.

Under the watchful eye of a ground crew, the L-15C Falcon entered the taxiway safely, turned a corner, and stopped at the junction of the two lanes.

The female controller at the airport tower seems to be a cute girl, her voice is still crisp and pleasant, giving a series of ground parameters and take-off permissions.

"Boom!"

The L-15C Falcon turned to the right and entered Runway 1, the engine roar became more and more intense, and the two S-17 turbofan engines were raised from a small thrust state to a medium thrust state, providing a continuous source of energy for the body.

After taxiing at high speed for about 220 meters, the L-15C Falcon floated with a thin stream of water flowing on the fuselage, raising the nose of the aircraft, like an eagle, soaring towards the cloudy sky.

"The weather forecast shows that Cumulus clouds are at an altitude of 3,000 meters, climb to 4,500 meters, and first practice basic flight maneuvers." After waiting for the fuselage to take off normally, Yang Xiaolong opened the tactical tablet terminal, clicked on the screen to obtain the latest weather forecast data, and gave new instructions to Zhou Hai.

"Yes." Zhou Hai heard the arrangement and kept climbing along the predetermined route.

Soon, just over thirty seconds later, the L-15C Falcon broke through the blockade through the layers of cumulus clouds, climbed to an altitude of 4,500 meters, and ushered in the dazzling sunlight, and the slightly gloomy atmosphere in the cockpit disappeared.

Zhou Hai held the metal joystick, his face was confident and calm, the lever was changed, his left foot was full of rudders, and he began today's flight training.

If you want to have excellent flying skills, you need to accumulate experience and hard training, Zhou Hai can fly as he wants in the Chujiao 6, but he can't do it with the L-15C Falcon.

First of all, starting from the left turn, then the right turn, the five basic flight movements are one after another, without the slightest sense of rustiness, and the smooth completion is done.

After doing the first five basic movements, Yang Xiaolong did not shout to stop, and Zhou Hai silently repeated the flight.

Twice!

Five times!

Ten times!

Expensive aviation fuel is constantly consumed, and repetitive training has allowed Zhou Hai to accumulate more and more experience, and the operation is skillful, and the five basic movements are getting faster and faster.

Thirty minutes later, Yang Xiaolong's calm and powerful voice sounded: "Okay, horizontal figure-eight, diagonal somersault, high yoyo and roller." ”

"Yes!"

Zhou Hai, who had continuously repeated dozens of basic movements, responded with a sound and controlled the L-15C Falcon, which happened to be in an upside-down state, to roll to the right, and after resuming positive flight, it turned right and circled and flew.

Like a somersault on the horizontal plane, the L-15C Falcon flies forward, then turns to the left, flies in an arc, and pulls out another somersault.

At 4,670 meters in the sky, a horizontal figure-of-eight pattern is presented, and the L-15C Falcon continues to gain momentum, and at a speed of nearly 400 kilometers per hour, it enters the front section of the diagonal somersault maneuver at a tilt of 45 degrees on the right side.

After a tilted somersault flew, he followed Zhou Hai's most familiar Gao Yoyo maneuver, raised his head to climb and roll to gain a height advantage, and then exchanged altitude for a speed advantage.

At such altitudes, the aerodynamic efficiency of the monoplane, flaperon and rudder in the sweep is at its best, and the energy loss is barely noticeable during the climb, and it softly makes a dazzling high-speed maneuver.

Finally, it is a simple and practical roller, which has both offense and defense, and fights the comprehensive flight performance of the fighter and the wisdom of the pilot.

In less than a minute, a set of four basic tactical actions was flew, Yang Xiaolong still did not shout to stop, Zhou Hai knew what it meant, and carried out repetitive training.

Five minutes.

Ten minutes.

Thirty minutes.

Flying over and over again, at the cost of fuel consumption and flight wear, Zhou Hai accumulated valuable flying experience.

Why is it precious?

Because the one-hour basic action and basic tactical flight training alone cost about 100,000 yuan.

100,000 per hour, the higher education aircraft requires graduates to fly 200 hours, and this stage will cost 20 million yuan.

Yang Xiaolong's voice sounded on time: "Okay, put on your glasses, climb to 14,000 meters, the high-altitude stall tailspin subject is very dangerous, I'll show you how to change it first, you can operate it again, understand?" ”

"Understood." Zhou Hai took a deep breath, pulled the lever up to operate, and the L-15C Falcon, which was in the midst of the drum maneuvering, quickly changed its flight attitude and faced the sky higher overhead.

The training of stall tailspin subjects for higher education students generally has to reach a height of more than 10,000 meters, and even the higher the better, because the higher the altitude, the greater the reaction time and operation space left for you.

In the state of stall tailspin, its own speed is extremely low, about 100 meters per second, if it accidentally enters the stall tailspin at low and medium altitudes, because the reaction time is too short, the probability can not be successfully changed.

If there are no villages or cities on the ground, they must eject to escape immediately.

The reaction is slow, I'm sorry, I'm reincarnated with a ticket, and if you're lucky, you may be able to cast a good baby.
