Chapter 450 ? Turn on the De-Icing System

Chapter 450 Turn on the de-icing system

Several big soldiers carried guns and got into the woods, and then a series of gunshots rang out, and then several birds that may have been slow to react flew into the sky in fear and flew away far away.

In the cockpit, Li Zhanlie smiled and said, "What a crude way to repel birds, I like it."

Liu Changxi smiled and said, "Only Chief of Staff Tang can come up with such a method."

It is obvious that the sound of gunfire is used to scare the birds rather than to kill them. Tang Guozheng acted in a measured manner. He might encounter rare birds and he was absolutely not allowed to fight them, but there was no problem at all in using the sound of gunfire to scare them away.

There are very few aircraft taking off and landing at the Central South Station, and as an alternate landing station, it is restricted by its location. Even if there are fighter planes that need to make an alternate landing, they usually try to choose Guibei or other stations, so the birds here are not sure where the aircraft is. So I am not too afraid of the sound of aircraft engines.

The field company's emergency bird drive operation actually drove out several groups of birds, which made everyone break into a cold sweat again. Maybe it was because of the bad weather in the past few days that the birds were stifled, so when they finally encountered a sunny day, they were reluctant to leave the place where they often visited.

After struggling for more than half an hour, I finally determined that there were no birds within the prescribed range that could threaten the take-off of the plane.

Tang Guozheng issued the takeoff order for the second time, and Li Zhan's crew operated fiercely for the second time. However, this time Liu Changxi was careful and no longer focused most of his attention on the instrument panel, but allocated part of it to the instrument panel. Observe the airspace ahead.

"Reached take-off speed! Pull the nose!" Liu Changxi shouted loudly.

Li Zhan repeated his command, "Pull the nose of the plane!" At the same time, he pulled up the control stick, the plane raised its head, and the nose landing gear lifted off the ground, showing a take-off elevation angle. In order to allow the plane to obtain the most lift in the shortest time, Li Zhan adjusted the elevation angle. It has reached the maximum allowed, but the runway is almost exhausted.

Everyone's hearts were in their throats again.

There are two worries. The first is that the elevation angle is too large, causing stalling, and the second is that the rolling distance is not enough. Both concerns are closely related to pilot skills. Especially for the latter, the gap of 300 meters needs to be made up by the pilot's skills.

But it is obvious that everyone has great trust in Captain Li's ability at this time.

The aircraft's main landing gear rolled at high speed on the remaining runway, the tires rolled over the last section of the runway, and the aircraft completely lifted off the ground. Just when everyone was about to breathe a sigh of relief, the plane suddenly sank and disappeared at the end of the runway.

"Two, five, two! What's going on?" Tang Guozheng asked urgently in his heart.

Before I could receive a reply, the plane suddenly appeared again. It felt like someone was taking off his pants and squatting down to relieve himself in the wild. When he suddenly noticed someone coming over, he quickly picked up his pants and stood up, pretending that nothing happened.

Everyone in the tower breathed a sigh of relief, but they had no idea what Li Zhan's crew had experienced in the past few seconds.

"Can't pull the lever! Keep your stance, keep your stance!"

"Yes! Yes! Keep your attitude! It will climb!"

Li Zhan and Liu Changxi had the above conversation when the fuselage suddenly sank. The two experienced people knew very well that pulling the lever rashly would put the plane in danger of stalling. Under normal circumstances, when most pilots encounter a sudden sinking of the aircraft, they will subconsciously choose to pull the lever to raise the nose of the aircraft in order to allow the aircraft to climb. In fact, Li Zhan and Liu Changxi knew very well that the plane actually just needed some more acceleration distance.

At this time, there are no obstacles below the aircraft, and the bottom-up south wind will cause the aircraft to climb quickly.

Making such a decision requires great courage, but for Li Zhan and Liu Changxi, who are often flying on the tip of a knife, this is nothing.

The Y-8F-400 No. B-25277 entered the climbing stage. When they saw it flying over the mountains to the north, the people on the tower truly felt relieved.

"Two, five, two, you contact Central South Air Traffic Control 188.39 and follow his command. It's over." Tang Guozheng called Li Zhan and handed over the command directly to the Central South Air Traffic Control Center instead of the regional approach.

Li Zhan was in charge of radio contact. He and Liu Changxi repeatedly checked the frequency, and then the latter entered the new frequency and called Zhongnan air traffic control, "Zhongnan, this is Postal and Airline two-five-two."

Non-flight flights therefore do not use flight codes.

Zhongnan Air Traffic Control had long been notified that a special air traffic controller was waiting for special flight guidance. He quickly checked the radar screen, confirmed the plane's position, and immediately replied, "Postal Airways is turning around in twos and fives. I saw you on the radar, heading 180, altitude 1500, transponder recognized, please climb to 2000, over."

"Climb to 2000. Understand. The Postal Service will make a two-five-two turn." Li Zhan kept the plane climbing at a constant climb rate, and soon reached an altitude of two thousand meters above sea level.

Randomly, the Central South Air Traffic Control guided the aircraft to make a 180-degree turn, from due south to due north, and the flight altitude reached 7,000 meters. This is the special navigation altitude temporarily allocated to aircraft B-25277. That is to say The plane has a dedicated route.

The Postal Service is very smart. Without the help of troops, it would be difficult for them to obtain dedicated routes. A dedicated route is particularly important for the damaged B-25277 aircraft. There is heavy traffic in the sky, and cargo flights usually need to frequently adjust their altitude to avoid passenger flights. This is not a problem for normal aircraft, but for this damaged Y-8F-400, maintaining a smooth flight can minimize the risk.

Flying north along the dedicated route through Shanyue Province, Li Zhan's crew needed to pay attention to the weather. The weather conditions get worse as you go north. The cold air coming from Siberia is affecting most parts of our country and has brought serious signs of ice and snow disasters to the south.

Li Zhan was actually ready to climb to a higher altitude to avoid the bad weather ahead.

"Turn on the de-icing system." Li Zhan said.

Liu Changxi turned on the de-icing system, "Turn on the de-icing system. I said, is there really no problem with this thing?"

"No problem." Li Zhan said, "We have no problem carrying four engines."

It seems to be a relatively risky move. The accident originally occurred because of a problem with the logical relationship between the de-icing system and the engine protection device. It obviously requires great courage to continue to use the de-icing system. However, in fact, if you understand the logical relationship here and avoid operations that may cause problems, you can completely allow the power system and the de-icing system to coexist peacefully.

The most critical thing is that the plane is empty at this time, with nothing except a few tons of fuel enough to fly to the 012 aircraft factory. This greatly reduces the load on the engine and makes the plane more flexible.

Taking a step back, even if two engines stall again, the aircraft can calmly choose a very suitable alternate airport with the remaining two engines, without following in the footsteps of its predecessors.

"Oh, it's windy and snowy ahead. It wasn't mentioned in the weather forecast." Liu Changxi looked ahead. About twenty kilometers away was a dark mass with occasional high-altitude lightning. This is the bad weather airspace that needs to be avoided. .

Li Zhan said, "Ask air traffic control about the weather conditions and apply for a detour."

"clear!"
