At dusk, over the Bohai Sea, there were orange-yellow seas and ships dragging long trails. Another cold air replenished, and the coast of the Bohai Sea in late winter was clearly felt that the temperature was dropping rapidly.
The No. 037 J-7eggh flew about 500 meters below an Airbus-330, and around it, there were seven civil aircraft flying in different directions at various altitude levels.
Civil aviation also has evening rush hour.
While each household was preparing supper, Li Zhan continued to fly towards the base while descending altitude. According to the instructions of the tower, he used the method of landing the passenger plane to pull the altitude down process for a long time.
He began to slowly lower the altitude at about fifty kilometers away from the base.
Without knowing the angle of attack, Li Zhan could only rely on his feelings to make judgments and then make fine adjustments.
(Pitch angle and angle of attack are not the same concept.)
Fortunately, the fighter jets are in the southeast direction of the base, with the landing direction and takeoff direction consistent, otherwise Li Zhan will face a small difficulty - landing with the wind.
The base is ready, and relevant military and local departments have made preparations according to the plan. All aircraft below 4,000 meters ahead of the No. 037 J-7eggh have been adjusted, and all aircraft about to enter have received orders to fly around.
Three busy international routes passed through this airspace, and three large passenger planes that had entered the landing procedure received instructions to climb and avoid.
Old Chen issued adjustment orders to Li Zhan in time, and Li Zhan's feedback was very accurate. From the ground radar display, the No. 037 J-7eggh basically flew along the special landing route quickly formulated by the staff.
.This gives everyone full confidence.
At a location ten kilometers away from the base, the flight altitude of the No. 037 J-7eggh has dropped to 200 meters. According to the special landing route, it should be a special emergency landing route. The No. 037 J-7eggh must continue to slowly descend the altitude, and then
Minimum angle grounding.
The runway has been cleared.
"Calve three times, go to the left three degrees, don't worry if you move slowly." Old Chen saw that the nose of the machine was not fully aimed at the runway.
"I understand! Three degrees to the left." Li Zhan carefully adjusted the nose to the left and stopped the movement based on his feelings.
After seeing the nose of the No. 037 J-7eggh and the central axis of the runway were combined, the radar officer gave a thumbs up excitedly.
Old Chen said, "Houn Sangui, put the landing gear!"
"clear!"
Li Zhan released the landing gear. The landing gear switch was a hard switch and hydraulic mechanical transmission. He used a flashlight to break the switch to the "fall" position. Then the fuselage shook slightly, and the sound under the front and rear landing gears could be clearly heard.
"The tower, the landing gear has been put down." Li Zhan reported.
The staff officer used a telescope to observe and could vaguely see the landing gear of the No. 037 J-7eggh. He reported, "It must have been put down, but the distance is too far, and it is impossible to confirm whether it is in place."
Letting go is one thing, and whether it has been put in place is another.
The No. 037 J-7eggh has no chance to pass the field, and it is very difficult to guide and align it again if you miss the runway.
Old Chen thought for a moment and gave Li Zhan a new order, "Dong Sanguai, your current speed is 380 kilometers. If you collect the accelerator, reduce the speed to 280 kilometers."
"I understand." Li Zhan continued to operate cautiously and immediately reported quickly, "Please confirm the speed."
The radar officer once again gave a thumbs up and was impressed. Li Zhan's execution of the instructions was in place at one time, and even made people suspect that the cockpit had no power outage at all. Without feedback information, he only used experience to execute the ground guidance instructions and was in place at one time.
, This skill is very profound.
"The descent rate is three meters, and it will be grounded in one minute." Old Chen looked at the data quickly calculated by the staff members and nodded slightly.
Li Zhan confirmed the information, "The decline rate is three meters, one point is grounded."
"Listen to my instructions to collect the accelerator."
"I understand, I'll follow your instructions to collect the accelerator."
The No. 037 J-7eggh, like a sleepy man who was lazily touching his phone with his eyes closed, slowly approached the southern end of the runway. One kilometer away from the southern end of the runway, his flight altitude was already very low, only from the ground.
Fifty meters high. Such an emergency landing route is completely incompatible with the regulations. However, special circumstances are treated with special conditions. The worst result is a crash, with a lower flight altitude at least a lighter fall.
The staff quickly observed the landing gear of the No. 037 J-7eggh and reported: "The front and rear landing gears are all in place!"
The last operation is fine, the most difficult part is here.
Now, except for Lao Chen, the rest of the people's moods have changed from being desperate to beginning to having hope to being excited to being excited now, and this process of change has never happened before. The flight of the dark cabin is blocked.
The canopy cover is now happening that Li Zhan is also blindfolded and has suffered an oxygen supply system failure. Almost no one believes that Li Zhan can drive the fighter jet back - because almost no one can do without the fighter jet posture
Under feedback, the ground guidance instructions are 100%.
However, from the time of encountering a failure to the present, every operation of Li Zhan has fully complied with the requirements of the ground guidance command, and as of now, all of them have been in place at one time.
This person has a profound attainment in flying the J-7 series fighter jets - this is the strongest feeling of the staff.
From impossible to success, most people's mental journey has changed from low to high in this process. Everyone began to really pay attention to Li Zhan, a student who "does not take the exam", from seven consecutive times
I have been catching the second blocking rope and encountered extreme dangers. Every manipulation is much higher than the standard in textbooks, which is naturally admirable.
"Dongsanguai listened to my command to touch the ground, do you understand?" Old Chen stared at the posture of No. 037 J-7eggh and said in a deep voice.
The tower is very quiet, with only the sounds made by the instruments. Most positions have completed their own work, and the commander, radar and signal officers cannot be taken lightly.
The signalman is a sergeant. He stared at the landing gear and repeatedly confirmed whether the position of the landing gear was correct. If it was not correct, he must report it as soon as possible. Usually, he would fire in front of the landing fighter as soon as possible.
Red signal flare, the pilot immediately pulled up and returned to the flight after seeing the red signal flare, and then the signal flare reported to the commander. Because the war opportunity is often grounded within two or three seconds, the pilot must be notified first and then reported to the commander.
The sergeant finally breathed a sigh of relief. The signal gun he held tightly slowly returned to the specified position on the desktop, and closed the insurance at the same time.
Old Chen started counting down, "Ten! Nine! Eight!..."
"Touch the ground!"
Li Zhan quickly carried out landing operation, and the rear landing gear tire of the No. 037 J-7eggh was grounded, and two light smoke suddenly raised. Next, it all depends on the pilot. Li Zhan made the front landing gear touch the ground with the feeling of the pressure rod.
When he felt that the fighter's posture was stable, he decisively retracted all the accelerators and stepped on the brakes.
The No. 037 J-7eggh glided forward "sizzlingly", and the emergency rescue vehicles rushed over neatly.
After seeing the fighter plane stop steadily, everyone on the tower truly breathed a sigh of relief.
However, things didn't end there.
What exactly causes the No. 037 J-7eggh to fail twice in a row? The second failure is even a type that has never been encountered before.
It is unlikely to be a problem with the machinery.
