The leading edge flap transition light didn't turn on just now, right? "Yan Zhen's head is big, and the gourd scoop here hasn't been pressed, and the other one is up again.

Xu Qing buttoned the stubble, glanced upward, and sighed lightly, the leading edge flap indicator on the rear top plate did not show a green light, and the leading edge device was really not released.

"I was thinking about the inconsistency of the flaps just now, and I didn't pay attention to the leading edge flap transition light." Xu Qing replied honestly: "Brother, look! The leading edge device was not released. ”

Xu Qing motioned for Yan Zhen to turn his gaze to the leading edge flap indicator device on the rear roof plate.

Yan Zhen followed Xu Qing's instructions, looked at the indicator light that was not lit on the rear top plate, and sighed, Chen Yi's hand was a little ruthless!

Now the forked road between Xu Qing and Yan Zhen is not easy to walk!

"Brother, what do you say?" It was the first time that Xu Qing encountered a situation where he knew what the fault was, but he couldn't do the checklist.

Yan Zhen pondered for a moment, and couldn't come up with a plan for a while. But Wang Liang behind him began to arch the fire: "What are you doing?" Idle? Let's do something about it, don't waste time here. ”

Wang Liang was angry, and when he saw that Xu Qing and Yan Zhen were helpless, he felt sorry for himself if he didn't fall into the well and vent his anger.

The corner of Chen Yi's eyes swept Wang Liang, and Wang Liang at this time had an expression of watching a play, he just wanted to see Xu Qing and Yan Zhen make a fool of themselves. The corners of Chen Yi's mouth lifted slightly, showing a hint of mockery, and a four-word evaluation couldn't help but appear in his mind: "Jumping beam clown!" ”

Wang Liang still really thinks that he can sit firmly in the position of chief teacher? A person who pulls out a step when the power is handed over, if he is still so ignorant, it is likely that the position of the chief teacher will not be hot.

Wang Liang's arch fire was just an episode, Chen Yi didn't say anything to stop it, he was very curious about how Xu Qing and Yan Zhen would deal with it. To be honest, the difficulty of this fault is a little too much for the transfer teacher to check, and even when he first encountered this failure, he found a relatively reasonable solution by chance. And that solution is not unassailable, and it involves the captain going beyond the checklist.

As mentioned earlier, the captain is not unable to go beyond the checklist, but he must be cautious and not throw the checklist aside with his own understanding as soon as he encounters a problem that cannot be solved. What is the rationale? Just because you're a captain, isn't it a bit arbitrary to say that this checklist can't cover all the fault phenomena? Therefore, it is the safest to go beyond the checklist or not to touch it, and to find the basis in the checklist.

Yan Zhen now has a huge burden on his shoulders, plus there is a Wang Liang behind him who is sneering, and after thinking to no avail, he simply decided to change the starting point and said directly to Xu Qing: "You do the checklist of "Leading-edge Flap Transition" first! ”

In the end, Yan Zhen still wanted to put the difficult points aside and find a simpler direction to try.

"Oh, okay, okay!" Xu Qing couldn't make up his mind at this time, so he could only listen to Captain Yan Zhen's advice. Just now, starting from the inconsistency of the flaps, I couldn't even find a thread, so I had to settle for the next best thing and change the checklist to do it first.

"Fault condition: The leading edge device is not in the command position, this is yes!" Xu Qing said.

According to the normal operation characteristics of the flaps, the leading edge device should be fully extended at this time, but the indicator light of the leading edge device is not lit, which is obviously inconsistent with the command position, so the description of the first fault condition is consistent.

To mention here, the Boeing 737 does not have a component that directly controls the leading edge device, which is fundamentally different from the flap handle that can directly control the trailing edge flap.

So what commands does the leading edge device rely on? The linkage of the trailing edge flap!

The leading edge device and the trailing edge flap have a certain correlation, that is, when the trailing edge flap is extended, the leading edge device will extend proportionally. Generally speaking, when the trailing edge flap is placed in the position of flap five, the leading edge device should be in a fully extended state.

Now whether it is the flap handle or the actual position indicated by the flap, it shows that the leading edge device should be fully extended, but the reality is that it is not extended, so the leading edge device at this time is not in the command position.

"The leading edge device is asymmetrical!"

This is a description of the second fault condition, which is actually very similar to the third, and the third is "leading edge device skew"!

Now the leading edge device is not released, and it is not good to see if there is any asymmetry or skew, but as long as there is a situation, you can continue to check the list.

"Step 1, choose one!" The same is a multiple-choice question for fault phenomena!

"If there is a trailing edge flap released and the trailing edge flap position indication is inconsistent with the flap handle position, complete the trailing edge flap inconsistency checklist."

Xu Qing: "......"

It's back to a dead end!

Is there a situation where the trailing edge flap is released and the position of the trailing edge flap is inconsistent with the position of the flap handle? Apparently there is, huh?

Did the trailing edge flap come out? It's out, it's forty!

Is the trailing edge flap position inconsistent with the flap handle position? Inconsistent! The position of the flap handle is five, and the actual position of the flap is forty.

If it comes first, the problem comes back to the problem of flap inconsistency. And just now, Xu Qing and they couldn't find an entry point in the inconsistency of the flaps, so they turned to the problem of the transition of the leading edge flaps.

Now I have turned around, and the result of the checklist still has to turn back to the problem of inconsistent flaps, isn't this a closed loop, a closed loop that doesn't even have a wire.

Xu Qing has never been so helpless, he has gone all the way, from being cautious at the beginning to now he can be regarded as having seen the wind and waves and has some vision. Instructor Chang asked Xu Qing to lower his mentality, Xu Qing also accepted it humbly, he was willing to use the perspective of a second officer to observe the problems encountered in the flight, but there is one thing that cannot be erased, that is, Xu Qing's level is beyond the level.

Whether it is the regular instructor who allows Xu Qing to control the technical level beyond the level with humility, or Xu Qing himself, he clearly understands this. But today, Xu Qing's pride is ruthlessly crushed!

is so unmistakable, there are no vague failures, but Xu Qing is playing around, two checklists, two entry points, one stuck in step one, one stuck in step two, none of them have been done.

At this moment, he realized what it means to have mountains outside the mountains and people outside the people!

There is no need for any complicated failures, but a simple failure of the flight control system will make them at a loss.

Xu Qing's mind appeared with Chen Yi's grinning face, and he sighed in his heart: "Is this the height of the chief teacher?" ”
