"Tower, I'll report the situation, don't be afraid."

Li Zhan's voice was very clear, and he was cruising at a distance of 120 kilometers and 6,000 meters, so the reception of the shortwave radio station was very good.

But when Lao Chen Tou and the others heard these strange words, the first thing they thought of was: What do you mean we don't have to be afraid, you are a pilot, then you should be afraid, right? Then he was stunned: Hey, what do you mean, is there something wrong again?

"What's the situation in the three corners of the hole!" Old Chen Tou was not used to Li Zhan's problem, so he asked sternly.

Li Zhan replied, "My cockpit is powered off. ”

It's all stupid.

Even Old Chen Tou was a little stunned.

Li Zhan reported the situation to himself, "The display system should be turned off, the lighting system should be turned off, and the backup instrument is invisible, but the horizon is normal, but there is no backlight." ”

Old Chen Tou suddenly reacted, "The hole is three turns, has the cloth fallen off?" ”

"No, but I have a flashlight ......," Mr. Li said.

I actually carry a flashlight with me!

The pilots in this training did not carry standard equipment, otherwise there would be flashlights in the emergency biological products in the equipment, but Li Zhan actually brought a flashlight himself, what kind of predictive ability is this beyond human imagination?

"Troubleshooting, keep the course high, and don't move the throttle stick!" Lao Chen Tou quickly issued an order, and the three requirements were very correct, and the top priority was to let the No. 037 J-7EGGH maintain the current level flight status.

Li Zhan quickly replied, "Dong Sangui understands!" ”

Lao Chen Tou immediately ordered the emergency plan to be activated, and said to the staff officers around him, "Report to the command post and ask for the immediate emptying of all aircraft in the airspace in front of the three turns, especially the civil ones, and let their planes get out of the way!" ”

"Yes!"

The air traffic over the Bohai Sea is very busy, the routes are intertwined and look like a mess, and because there are several international airports along the coast, the flight altitude of civil airliners is usually in a continuous decline when entering the airspace of the Bohai Sea, and most of them are international flights.

According to the plan, the next instruction of the tower will be to require No. 037 J-7EGGH to descend to the flight altitude to avoid the busy route of civil aviation, but now Lao Chen Tou does not dare to do this at all!

The power outage in the cockpit meant that the pilot could not obtain flight data through the instrument panel and lost the grasp of the status of the fighter. Most of the data of the No. 037 J-7EGGH is presented through a one-flat and three-down display system, which means that the pilot has no other way to communicate with the fighter than two rods and two rudders.

The fortunate thing in the misfortune is that the horizon in the backup meter is still normal, but there is no backlight. However, Li Zhan can use a flashlight to assist lighting. It is very important for the pilot to grasp the pitch and roll status of the aircraft at all times, and at this time, Li Zhan can at least guarantee that he will not drive into the sea.

Lao Chen's side used the fastest speed to implement the emergency plan, and Li Zhan's side actually started to investigate according to the procedure a long time ago, and he found that the power supply was normal, so he concluded that the problem should be on the line.

Many people don't know that he had encountered the same danger in the air when he was working in the Second Division, that time it was a night flight, but at that time, after descending altitude, he could at least see the lights on the ground, and now he couldn't see anything outside the cockpit at all, which was even more dangerous than the last time.

After the investigation procedure was completed, Li Zhan reported, "Tower, the investigation procedure has been executed, and there is no result. I judged that there should be a problem with the line. ”

"Are the other systems working?" Old Chen asked.

Li Zhan couldn't move the throttle stick and the control stick and the two rudders, he replied, "I feel that the attitude of the fighter should be normal, and the thrust is very stable." ”

If it is the original old flight control system, Li Zhan's hand must always hold the joystick, and keep the fighter in level flight by constantly pushing the rudder, after changing the new flight control system, No. 037 J-7EGGH has an automatic trim function, which is an obvious feature of the third-generation aircraft.

In other words, as long as there is no problem, Li Zhan does not move the two rods and two rudders, and the fighter will continue to fly at a high speed according to the previously set course until the fuel runs out.

This is also the reason why Lao Chen Tou ordered him to leave the pole and rudder with both hands and feet for the first time.

Li Zhan suddenly frowned, and reported, "Tower, apply for the lower altitude, there seems to be a problem with the oxygen supply, and the amount of oxygen is decreasing." ”

Another glitch.

Flying at an altitude of 6,000 meters without oxygen supply, the pilots could not last long.

Before each flight, the plane needs to be refueled and recharged, what is the oxygen level? Take the J-7 as an example, it will not end up flying continuously for a whole day with one oxygen, so there will never be a shortage of oxygen. Eighty percent of the reasons for the decrease in oxygen volume are leaks or pump failures.

The plane didn't fly much, and it was kept from the manufacturer, and Peng Chubin's maintenance team was also very careful, and the reason should not be on the maintenance side. The most critical thing is that the cockpit power outage and oxygen supply failure seem to be two completely independent types of faults, and Li Zhan can think of only one that may connect the two - like the airspeed tube failure, it is a line failure caused by a high-salt environment.

Airplanes can also be unadaptable.

But Li Zhan had a strange feeling - the old man might not be very good.

Li Zhan can't count how many times he has made major changes and minor repairs, and he can't see the original appearance until now, in fact, the main structure is still the original old skeleton. It is undoubtedly a very test of skill for manufacturers to make such a big improvement on such a basis, but how the actual combat performance is has yet to be discovered.

Anyway, fly back first.

As long as the engine can still provide power, as long as the wing is not broken, Li Zhan is sure to drive the plane back.

Old Chen Tou immediately responded to Li Zhan's request, "Dong San turned down the height, the depression angle should not be too big, listen to my command to resume level flight, do you understand?" ”

"Dong Sangui understands!" Li Zhan got back on his feet and feet, and when he held the throttle stick and the joystick, he felt that the control of the fighter plane was back in his hands.

His movements were very gentle, gently pushing the rudder and slowly putting the lever while slowly retracting the throttle. An increase in the depression angle will increase the speed, so the action of throttle retraction is essential. In the situation of "isolation", Li Zhan could not let the fighter fly too fast, and there was a high probability that a fighter plane that had two kinds of failures in a row would continue to malfunction.

The atmosphere in the tower was solemn, and the radar crew stared closely at the display screen, representing the red dot of No. 037 J-7EGGH at a steady descent altitude, 5700, 5400, 5100...... Radar crews report every 300 meters, while closely monitoring the course and speed. The ground radar measures the speed of the fighter relative to the earth, that is, the ground speed, and there are some errors in the airspeed.

At 4,000 meters, Li Zhan took off the oxygen mask and breathed a heavy sigh of relief, slowly leveling according to the instructions of the tower, and finally resumed level flight at an altitude of 3,600 meters, and the course did not change. He picked up the flashlight on his left hand side and shone it at the horizon to make sure that the pitch and roll angles were in the correct position before reassuring.

There are no big problems with maintaining an attitude to fly, the big problem is landing.

At this time, several staff officers in the tower had already begun to urgently study the plan, and they had never encountered such a situation.

One of the major staff officers said solemnly: "In November last year, a certain unit of China Southern Airlines spanned day and night, and the power in the cabin of a flying leopard was cut off shortly after takeoff, which is very similar to the current situation. And at that time, the flight control system of the flying leopard was disconnected, and the pilot controlled it manually. ”

"It's different." Immediately, a senior lieutenant colonel staff officer shook his head and said, "The flying leopard of a certain department of China Southern Airlines was only powered off in the front cabin at that time, and the display in the rear cabin was normal. The rear cabin pilot guided the front cabin pilot to make a successful blind forced landing, which was more than 6 o'clock in the afternoon, and there was some visibility, and it was not very difficult to be honest. ”

The senior lieutenant colonel looked at the radar display screen and said in a deep voice, "The situation in Dong Sangui is even more dangerous, he can't see anything." ”

The combination of these two factors makes Li Zhan's situation much worse than the power outage of a certain flying leopard cockpit of Hainan Airlines. And he only has one engine, and if there is a chain of failures that affect the engine and cause engine failure, he can only be a paratrooper.

The major staff officer said, "There is no other way but ground guidance." ”

The senior lieutenant colonel nodded slowly, "Mr. Chen, you can only guide from the ground, mainly relying on the pilot's control." ”

Lao Chen didn't know that it was one thing to have guidance, and it was another thing whether the plane could be consistent with the guidance instructions, and in the final analysis, it depended on the pilot's skills.

Without hesitation, Lao Chen immediately called Li Zhan, "Dong Sangui, it is still the ground that guides you to land, pay attention to the margin when manipulating, understand?" ”

"Dong San Gui understands."

The flight of the dark cabin originally relied entirely on ground guidance, but now Li Zhan has no way to obtain the flight data of the fighter through the display system, and must wait for the ground to report, but the ground radar can only measure a few key data, and there is a certain time delay in reporting to Li Zhan about this process, so Lao Chen Tou specially reminded him to leave some margin when manipulating.

Zhang Xueyang, Cao Fufei and Tang Leilei also knew what was going on in the flight briefing room, and all three of them were very nervous, and even Tang Leilei, who had always been very concerned and knew Li Zhan's ability to deal with dangers, was a little gray.

It's really too difficult to encounter this time.

Zhang Xueyang remembered the most serious danger that Li Zhan encountered when he was in the Second Division, and he didn't know whether it was to comfort himself or to let Cao Fufei and Tang Leilei not have to be too nervous, he recalled and said, "Lao Li originally got off the army to the Second Division to open this hole, three turns, Jianqi and seven E, once I conducted air combat training with my wingman, Lao Li was on duty for combat readiness and went out on a mission, and when I returned, the weather suddenly deteriorated, and the weather changed very quickly, and I no longer had the landing conditions after I landed. ”

"Yes, yes, yes." Tang Leilei's memories also woke up, and he said in a deep voice, "At that time, the tower ordered the first brother to land in Guibei, but it didn't take long for a lightning strike to cause a fire in the engine compartment. As a last resort, the first brother returned to the field and made a forced landing. I remember that the gusts reached level eight, heavy rain, and the visibility was only a few tens of meters. At that time, we all thought that the first brother was going to ...... this time Who would have thought that the first brother had a successful forced landing! At that time, a small half of the fuselage was burning. ”

Zhang Xueyang nodded slowly and solemnly, "Yes, it's a miracle." Li Zhan is fully capable of dealing with the danger in front of him, and I don't think there is any need to worry too much. ”

At that time, the handling of the dangerous situation had already formed a case and was distributed to the aviation units of the whole army, and it was included in the second company's dangerous situation handling plan system as an optional plan under extreme circumstances, so Cao Fufei knew about this matter. The pilots privately commented on the top 10 classic air situation handling cases, and Li Zhan dealt with five of them......

The unofficial name of a near-miss expert is not for nothing.

Cao Fufei said worriedly, "At that time, there was visibility, but now he has no visibility at all, and there is no one in the cockpit, and he is almost like a blind man now." ”
