Chapter 45: The Landing of the "Lame".
"Is it fun?" Teacher Chang looks like a "villain" who has succeeded in his conspiracy.
It was in vain that he searched for a long time in the fault list, and there were relatively few failures in this landing gear, and they were all in English, so he still used the translation software on his mobile phone to find it.
Xu Qing was speechless, isn't this just going back more and more, as for being so happy?
"There's also a leading edge flap transition, a malfunction of the maneuvering system that goes to the landing where the trailing edge flaps are retracted to all the flaps that are retracted and landed, do you want to try it?" Instructor Chang was interested: "This part or all of the landing gear is still a little difficult for you to modify at the beginning, and the direction is not easy to control after landing, so there are few inspectors who come out like this when inspecting." However, the difficulty of landing with all the flaps is more suitable for you. ”
At that time, I didn't expect the failure of the control system in a hurry, and now I think about the difficulty of retracting and landing some or all of the landing gear to Xu Qing, which is relatively suitable for the captain.
"Wait for the second half, I'll drop this first." Xu Qing thought about it and felt that it was necessary to experience it again, and the instructors said that the failure of the control system was more likely to occur during the inspection, and Xu Qing naturally couldn't let it go.
"Huh? Do you still want to fall on this? "Instructor Chang looked at the time, there were less than ten minutes left, and it was definitely not enough to complete all three checklists.
However, the first landing gear inconsistent checklist is mainly to let the pilot check the backup indication system of the rear roof, Xu Qing checked it as soon as possible, which is often seen by instructors.
The second artificial landing gear is even simpler, and the instructor directly asked the two of them where the artificial landing gear was.
Both Xu and Qing knew that behind the center console, the cover plate needed to be opened, and there were three manually placed landing gear handles, corresponding to the front landing gear and the two main landing gears.
One thing to note is that the procedure for manually releasing the landing gear only involves the affected landing gear, which in this case is the left landing gear, and the rest of the landing gear does not need to be manually released.
At the same time, after the procedure of manually placing the landing gear is completed, the cover plate must be closed, otherwise the landing gear will not be able to be retracted.
Among the three checklists, some or all of the landing gear landing checklists were the most complicated, and the time was insufficient, so Instructor Chang asked Xu Qing and the others to jump directly to this checklist and let them do it completely.
The first step of this checklist is to choose whether to manually put the landing gear in operation, and if not, return to the manual landing gear checklist, so each checklist is linked.
Xu Qing and the others have already finished manually placing the landing gear by default, so go directly to the second step.
Evacuate!
That's right, the second step is to notify of the imminent emergency landing and evacuation.
It is extremely dangerous for a landing gear to not be lowered, and the friction between the fuselage and the ground can cause a fire or even an explosion, so once it is stopped, evacuation is carried out.
On real flights, evacuation procedures are explained during each coordination between the crew and the crew. If you really encounter a situation where the landing gear cannot be put down and you have to land urgently, the crew must communicate with the cabin crew about the situation before landing.
The third step is to reduce the grounding speed by considering the consumption.
The reference speed of the aircraft on the approach page is related to the full weight of the aircraft. The smaller the full weight of the aircraft, the smaller the reference speed. By consuming fuel, the weight of the aircraft can be reduced, and the approach speed of the aircraft can be reduced.
Because of the tight schedule this time, and the simulator training, it is definitely impossible to really hover and consume fuel.
The fourth step is to plan the flap 40 to land, which is the same as the third step, the approach speed of the flap 40 is smaller than the flap 30, and the flap should also be set up with the flap 40 when evacuating, so that it can also save time.
After that, the jump switch on the P6 board is pulled to prevent the landing gear from sounding a warning.
The jump switch of the automatic speed brake should also be pulled out to prevent the ground spoiler from accidentally sticking out after grounding.
At the same time, this time, the grounding does not pre-position automatic driving, and artificial braking is used.
Don't pre-position the airbrake, keep the lower clamp position!
"Don't pull the speed brake at the beginning of this landing, wait for the fuselage to start touching the ground before pulling, and the same is true for the reverse spray." Instructor Chang explained, and then patted Diao Jie: "After a while, you turn off all the fuel pumps before he flattens out." Pay attention to the direction with the handwheel, the rudder should not be controllable. ”
Diao Jie nodded again and again, and then made the checklist.
Ground Landing Gear Suppression Door, Suppression!
Ground proximity warning jump switch (P18 board), unplug it!
At the same time, the engine bleed air valve can be closed in the final approach phase, allowing the aircraft to release pressure in advance.
In the evacuation checklist, the pressurization selector is selected to the manual position, and the exhaust valve is fully opened to relieve the pressure of the aircraft, otherwise the cabin door may not be opened.
After doing everything, the rest depends on Xu Qing's manipulation ability.
The left landing gear was not released, and it had no effect on the maneuvering in the air, and the key to determining the success of this landing was whether it could maintain its direction after grounding.
500 feet, good data!
200 feet, decisive high, continue!
50 feet!
When Xu Qing began to flatten, Diao Jie quickly closed all the fuel pump electric doors.
Earthing!
The right landing gear of the plane was the first to be grounded, and Xu Qing kept carrying the right disc while pulling the rod to try to make the fuselage contact with the ground later, and then let the plane slow down at this time.
Not long after, the nose landing gear was also grounded, and then Xu Qing found that the plane had begun to move away.
"The handwheel keeps up!"
As soon as Xu Qing's voice fell, the fuselage met the ground, and the direction of the slide was thrown to the left.
Xu Qing's right rudder followed closely, the right disc was also full, and Diao Jie's handwheel was also used in time. Rao is so, the plane is still further to the left.
Xu Qing's heart was cold, this posture was not to rush out of the runway.
Miraculously, as the plane slowed down, the plane shifted to the left less and less, and stopped when it reached the runway sideline.
Xu Qing let out a long breath, and the nose of the plane crossed the runway side line a little bit, which was acceptable for the first time, at least the plane did not explode.
This was followed by a couple of evacuations, and nothing new.
"It's still slow!"
When Xu Qing and the others finished the evacuation procedures and began to restore the panel, Instructor Chang said: "You guys are still prepared, what if the landing gear breaks after landing, can the reaction keep up?" I think with the speed you guys just now, nine times out of ten, you're going to rush out. ”
"The landing gear is broken...... Xu Qing chewed in his mouth, if after grounding, the landing gear suddenly breaks, as far as the first time is concerned, then he will definitely not be able to control it.
There is a way, what is afraid of something, in the future, he will usher in the first failure of the career simulator because of the broken landing gear.
