"Okay."

Hearing Yang Xiaolong's instructions, Zhou Hai nodded, turned off the engine afterburner, adjusted the fuel supply, and waited for the L-15C Falcon to leave the supersonic speed and return to the subsonic flight area, then pull the rod back and turn back to the left with full rudder.

The fuselage slowly pulls out a graceful arc and returns to normal working condition, and the tail end sprays a steady stream of high-temperature air, which mixes with the air in the cold and extreme environment, and the water vapor condenses into two white wake clouds like ribbons.

These two trail clouds cannot be dispersed for a long time, like a painter's pen in his hand, at an altitude of 12,000 meters, outlining a wonderful scene like a picture scroll.

Make a U-turn and fly smoothly along the return course.

"Zhou Hai, you should know about the Academy's notice about the Skyhawk Military Exercise yesterday, right?" Yang Xiaolong, who was staying at the back of the cockpit, said softly.

When Zhou Hai heard this, he responded: "I know." ”

"According to this progress, you can basically participate in the exercise in August, and the Sky Eagle military exercise will perform well, and I only have one request for you, to break through to the Quzhou base for 300 kilometers." Yang Xiaolong exhaled and said, revealing his thoughts: "If you enter, there will be surprises waiting for you." ”

Looking at the blue sky in front of him, Zhou Hai was silent, his mind fell into thought, and he was a little puzzled: "Instructor Yang, is there no way to complete the combat mission of the military exercise?" Assuming that we penetrate the defense at ultra-low altitude, we may be able to avoid the Air Police 2000 and J-10 fleets. ”

300 km!

Yang Xiaolong's request was only to break into the position of 300 kilometers of the Quzhou base, which made Zhou Hai a little puzzled.

Why is this not seeking to complete the task and not seeking victory in the military exercise?

And surprise, what is it?

"You'll understand later, it's too early to talk about this, train hard." A smile appeared on Yang Xiaolong's face, and he did not reveal the details about the Sky Eagle military exercise, and responded.

Hearing this, Zhou Hai shook his head slightly, stopped talking, and flew with peace of mind.

He has to admit that whether it is his own master or the flight instructor Yang Xiaolong, including himself, they are used to saying this sentence when they don't want to answer questions - you will understand later.

The two S-17 turbofan engines maintained a small thrust state, and the L-15C Falcon, which flew at an altitude of 12,000 kilometers, also encountered a Boeing civil airliner about 20 kilometers away on the way back.

More than ten minutes later, the L-15C Falcon returned to the airspace around Shicheng along the route, gradually reduced its flight altitude, and swept towards the academy airfield, ready to approach and land.

"Call the tower, 109 is ready to enter the arena and request landing." Zhou Hai switched to the military encrypted communication channel and sent a landing application to the academy airport tower.

"The tower received, the ground wind is due south and southwest, the wind speed is level 3, the gust is level 4, there is no crosswind, the landing is permitted, please land on runway 1." The crisp and ethereal voice of the female tower controller sounded, quickly giving a series of ground parameters.

"Received on the 109th, ready to land."

Zhou Hai held the flexible and lightweight metal joystick, pressed forward slightly, stepped on the rudder with both feet, controlled the aircraft to change its attitude, and entered the outer range of the airport, so that the nose of the aircraft was aimed at the No. 1 runway.

On the ground, a ground crew member looked up at the sound, and his eyes were focused on the L-15C Falcon that was about to land, the king of the higher education aircraft with an extraordinary status in the entire academy.

The speed is reduced, the flight altitude is reduced, and the attitude is correct and smooth.

With the screeching of engines resounding around the runway, the silver-gray L-15C Falcon showed an elegant attitude, the three-point landing gear on the lower side of the belly slowly poked out, the Bayi logo in the middle of the single vertical tail was in full view, and the nose of the aircraft was slightly raised several degrees.

The landing speed of the L-15C Falcon is very friendly for the high school instructors, only 200 kilometers per hour.

If the flight performance is poor and the design is outdated, the landing speed is as high as 330 kilometers per hour.

This figure is a nightmare for every pilot of the higher education aircraft, and there is a gap of 130 kilometers per hour between the L15C Falcon and the higher education.

Don't underestimate this gap of only 130 kilometers, in the rigorous and demanding atmosphere of aviation, the landing speed and stall critical reduction of 10 kilometers per hour, a step forward, requires a strong aviation industry and a series of cutting-edge aviation technology as support.

Even the Mountain Eagle Gaojiao, which was born from Jianjiao VII, still has a landing speed of up to 260 kilometers per hour, which is far inferior to the L-15C Falcon.

"Squeak!"

The high-performance tires of the landing gear come into contact with the surface of the concrete runway, causing friction, rolling at high speed, slightly deforming, and emitting a faint and sharp sound, hidden in the engine sound.

The slightest and unavoidable bump spreads throughout the fuselage, and the wing-body design and fly-by-wire flaperon system greatly reduce the impact of undisturbed wind speed and dense airflow during landing.

"Bang!"

Immediately afterward, a dull sound was heard, and the closure device at the end of the single vertical tail opened, and a white umbrella flower immediately bloomed, fully propped up, providing a resistance area, and decelerating with the flaperon and spoiler.

The L-200C Falcon, which has a speed of up to 15 kilometers per hour, rapidly reduces its gliding speed.

"It's so handsome, there are only four new falcons in our academy, if only I could have made it to the crash course, maybe I could get one to try." A senior instructor sitting in the cockpit of the Mountain Eagle B, his eyes watched the L-15C Falcon with a science fiction atmosphere gliding smoothly in the No. 1 runway, revealing a strong color of envy.

The flight instructor's faint words came from behind him: "Boy, wake up, don't daydream, fly your own well, and prepare for takeoff." ”

"......" Hearing the teacher's words, the body of the Higher Education College stiffened, and he sighed in his heart, and his eyes showed resentment.

After landing safely, Zhou Hai held the joystick and controlled the war eagle under him to drive to the taxiway.

The L-15C Falcon, which gathered the attention of many people, left the No. 1 runway and entered the taxiway, and the two Mountain Eagle A higher education planes that were waiting at the starting point of the standby runway drove into the runway one after another to accelerate take-off and carry out flight training.

The entire airport once again fell into a state of high-intensity training.

Flight!

This is the most important task of the higher education stage, the theme of life of every cadet.

"Buzz!"

Soon, the L-15C Falcon, which was traveling on the ground at a speed of tens of kilometers per hour, entered the apron area, and under the arrangement of a ground crew with a flag sound, turned into the No. 20 shed apron and came to a steady stop.

Zhou Hai's hands beat flexibly, turned off the two S-17 turbofan engines in order, returned the fuel supply switch, checked the flight parameters displayed by the onboard avionics system, everything was normal, there was no problem, and then turned off the avionics and cut off the power supply.

The roar of the engine gradually subsided, the hot air flow disappeared, and the white umbrella flower hanging from the tail of the plane fell weakly.

The ground staff who stayed around the shed apron quickly surrounded it.
