What did you say? What does it mean to not go down? Did the checklist go wrong? Xu Qing didn't quite understand what Yan Zhen meant, how could there be a situation where the checklist couldn't be done.

"The checklist should be right, the flaps are not inconsistent, isn't it obvious, or I'll fly, you look at the checklist?" Yan Zhen couldn't say it clearly, so he directly let Xu Qing experience it himself.

Xu Qing looked at Yan Zhen and then glanced at Chen Yi, Chen Yi was sitting on the console, everything was under control, Xu Qing suddenly felt that something was wrong.

"Brother, that's manipulation!" Xu Qing couldn't figure out Chen Yi's context for a while, but he still didn't believe it, such an obvious fault couldn't be done according to the checklist?

"Take the manipulation! If you look at the checklist, the problem is in step two. When handing over the manipulation, Yan Zhen also specially reminded Xu Qing.

"Step two?" Xu Qing opened the electronic manual and first looked at step 1: "Is there a trailing edge flap asymmetry?" ”

Step 1 is an option, if there is flap asymmetry, you need to do a flap asymmetry checklist first. This mainly involves the problem of spare flaps, and there is no asymmetry protection for spare flaps, and the problem of flap asymmetry must be dealt with first, otherwise the flaps cannot be inconsistent.

Whether there is a flap asymmetry problem can be determined by the flap position shown on the flap finger table, or disconnect the autopilot to see if the aircraft has spontaneous deflection. If there is flap asymmetry, the aircraft should have spontaneous deflection.

Xu Qing pretended to disconnect the autopilot and spread his hands, it stands to reason that the plane should be in a stable state, but the moment he disconnected the autopilot, as soon as his hand was released, the plane immediately began to deviate.

It's embarrassing! What's the matter?

This broken simulator is already unstable, and now it is in a dilemma.

Is that a flap asymmetry? Xu Qing is like a mirror in his heart, there is no flap asymmetry at all now, it's just that the simulator itself is unstable.

But it's a bit hard to ride a tiger right now......

Yan Zhen showed the captain's courage at this time: "This simulator is unstable, and the state of the aircraft after disconnecting the automatic driving is not used as the basis for judging the flap asymmetry, let's use the flap finger table as the judgment standard, and the current conclusion is that there is no flap asymmetry!" ”

Xu Qing subconsciously looked at Chen Yi's face, whether this conclusion could be accepted by Chen Yi was the key to the problem. Fortunately, Chen Yi's face remained unchanged, and he didn't seem to hear Yan Zhen's words at all.

Xu Qing saw that Chen Yi didn't say anything, so he also admitted Yan Zhen's statement, and chose not to have the asymmetry of the trailing edge flap in step 1.

If there is no flap asymmetry, then enter the second step, which is the problematic step that Yan Zhen just said, Xu Qing is also extremely curious about this.

"Step two, choose one of them......" Xu Qing slowly read out the checklist, this step is still a choice.

"If the indicated flap position is greater than or equal to thirty and less than forty!" Xu Qing read out an option.

Note that the statement in the checklist is not the position of the flap handle, but the position of the flap indicated by the flap finger meter, and the two should not be confused. Judging from the flap finger chart, the position of the flap forty is indicated, which obviously does not meet this option.

Xu Qing quickly came to a negative conclusion, Yan Zhen nodded on the side, agreeing, then it was the second option.

"If the indicated flap position is greater than or equal to fifteen and less than thirty!"

With the experience just now, Xu Qing still rejected this option. There is no difficulty in the selection of options, but Xu Qing's heart is shrouded in a layer of haze, and the faint sense of unhappiness is becoming more and more obvious, and he kind of understands what Yan Zhen means when he says that he can't do the checklist.

The third and final option!

"If the indicated flap position is less than fifteen!"

Thinking of this, Xu Qingqing completely understood what Yan Zhen meant, and the helplessness on Yan Zhen's face just now turned to Xu Qing's face in just a few minutes.

Is the third option hard to choose? It's not hard! The answer is obviously no, but such determination is also what makes Xu Qing and Yan Zhen difficult.

This is the last option, and now none of the three options are correct, how can this checklist continue?

The most important thing is that there is no hesitation in the choice of these three options, at least for Xu Qing's first thought. This is the most terrifying, which means that Xu Qing can't find any suspicious points, so the checklist will be stuck at this point!

Xu Qing compared the three options one by one again, for fear that he had missed something just now.

It took a few more minutes, just three lines of words, Xu Qing couldn't wait to break it open word by word, but the result was still that he couldn't find any problems with understanding. What he understands is what he sees, there is no deviation, and the sentences on the checklist are not very complicated, and basic elementary school students can understand them.

So the question is, I know every word, and the connected sentences are also understandable, so why can't I find an option that meets the current situation?

"I just glanced at this problem and this checklist ...... Can't do it! Yan Zhen sighed. Now Xu Qing also stopped here, indicating that his doubts just now were justified. Similarly, he looked back on it later, but he still couldn't find the starting point of the checklist, and the two of them had no clue together.

Xu Qing scratched his head, he was about to scratch the top of his head, and he couldn't figure out a way to break the game.

"It's not! Is there a problem with this checklist? Why is there no option for flap forty? Xu Qing scratched his ears and cheeks and was bored, he couldn't help it, and his mouth began to be unforgiving again.

You said that the first option added something "and less than forty", how good it would be to remove these words, and it would not make the two of them sit here and stare at each other.

Xu Qing was very irritable, but Chen Yi was refreshed, and coughed lightly: "Yes!" Why don't you have the option of flap forty, doesn't this stump our Brother Xu? What are you saying Boeing is doing, such a big hole can be exposed, isn't it! ”

Chen Yi said, patted Wang Liang's shoulder, and pulled Wang Liang to start the taunt mode together.

Facing the ridicule on Chen Yi's face, Xu Qing pouted, what's wrong with Chen Yi today? Did you go out without brushing your teeth? Mouth so stinky? If one person is not enough to mock, you have to pull another person.

Chen Yi's mutation just made Xu Qing puzzled for a while, what he really needed to deal with was the problem of flaps, but now they really had no clue.

"Let me remind you, it's not just the flap inconsistency now, look ahead!" Chen Yi's lazy voice sounded.

After Chen Yi's reminder, Xu Qing suddenly found that the leading edge flap transition light was ...... It's lit up!
