Why is there a cut-off point of 80 knots, because after 80 knots, it involves the relatively dangerous problem of high-speed interruption.

Don't confuse simulators with real situations, the two are almost completely different concepts.

The simulator seems to be easy to interrupt at high speed, but in fact, Xu Qing once heard Senior Brother Shi Jing say that when he was just transferred to captain, he once encountered a wind shear warning after 80 knots, and it was interrupted at 120 knots, and when the plane stopped, his hands were shaking.

The captain is still like this, which shows how high the risk factor of high-speed interruption is, so the regulations of various airlines for high-speed interruption are relatively strict.

Even under such strict regulations, Shi Zhonghao still chose to interrupt, which is exactly what Xu Qing was puzzled about.

He had a hunch that Shi Zhonghao seemed to be in trouble!

"Blue 9657, interrupted, now off the runway!" The first pair quickly reported that the takeoff was interrupted, and the plane detached from the runway along the approaching breakout.

"Blue 9657, F, F6 pre-etc!" Tower Command!

After leaving the runway, the first pair completed the separation procedure, and during the period, he also wanted to stop talking.

Of course, Xu Qing knew why, after 80 knots, according to the regulations, only the engine failed, the wind shear and fire alarm could be interrupted, and the low amount of engine oil was not among them.

In other words, there is a problem with Shi Zhonghao's decision to interrupt this decision, as PM, he has the responsibility of monitoring the captain, and if the company decides to punish Shi Zhonghao, he will not be able to escape.

It's just that Shi Zhonghao's expression is serious now, and the co-pilot is a little afraid to ask.

When the plane taxied to F, the plane entered the stage of taxiing in a straight line, Shi Zhonghao didn't wait for the co-pilot to ask him, he first said: "I am the captain, I will be responsible for the decision to interrupt the takeoff, you will be fine." ”

The captain has already made it clear that he is carrying it, and the co-pilot is not good at asking, but he must not be able to pick up this matter, Shi Zhonghao is willing to take more responsibility, but it is just that he can be punished a little less.

Now that the interruption of take-off has happened, it can't be changed, and the punishment can't be escaped, and at present, he actually wants to know why Shi Zhonghao chose to interrupt the take-off. In case there is something that he didn't expect, the captain must have his own reasons for interrupting, and I don't know if the company will accept this reason.

"Blue 9657, may I ask what is the reason for your interruption?" Tower asked.

Shi Zhonghao gave the co-pilot a gesture and motioned for him to answer: "We have some problems with the engine. Shi Zhonghao deliberately blurred the question.

"Remember how many verses were interrupted?"

"It's like you're in your early 100s."

The tower waited for a while: "Blue 9657, then did you decide to go back to the seat?" ”

"yes, we're going to go back and check the engine." Shi Zhonghao replied that the low amount of oil in the engine is a big problem, which can directly cause the engine to shut down, and it is absolutely impossible to take off again.

"Do you have a problem with the engine, does it affect the taxi, do you need a tow truck?" The tower was quite thoughtful, thinking that Xu Qing had a problem with their engine, which might affect the taxiing, so he asked a special question.

"Gliding for the time being has no effect, Blue 9657!" Shi Zhonghao rejected the tower's kindness.

"Okay, then blue 9657, you are waiting for the guide in front of F6, and you can take the guide report!"

"F6 front, pick up the guide newspaper, blue 9657!"

Xu Qing and they have been sliding to F6, but the guide car has not yet come, this kind of temporary carrying, the guide car generally takes some time.

While waiting, Shi Zhonghao thought about himself.

The most direct consequence of the low amount of engine oil is that the engine is turned off, which is not a change. Unlike some faults that can be dealt with and recovered, the amount of lubricating oil is less, and it will not be increased out of thin air when the pilot's operation is not done, as long as the lubricating oil amount is lower than the red line, that is, to do the "engine failure or shutdown" checklist.

This is plainly written in the QRH!

In other words, as soon as they take off, they will be ordered to be single-handed.

In the case of the two dangers of single engine and high-speed interruption, Shi Zhonghao briefly evaluated, the lesser of two evils, he chose high-speed interruption!

This is also the reason for his hesitation, and the decision to interrupt the takeoff is the result of his careful consideration.

"But! According to the company's regulations, it is clearly written...... Will the Safety Supervision Department accept it? Xu Qing is worried about this, Shi Zhonghao's reason, at first glance, there is still some truth, the problem is whether the safety supervision department accepts this reason.

The group of rigid old stubborn people in the Ministry of Safety Supervision, Xu Qing didn't believe that they would be willing to turn a corner and give Shi Zhonghao "amnesty".

People are self-interested, and dealing with Shi Zhonghao in accordance with the company's regulations is simple and does not leave a handle. If you want to determine that Shi Zhonghao has no problems, you have to list a lot of evidence, and the results of the disposal must be supervised by everyone. Once someone finds a loophole in the argument of the safety supervision department's handling results, the safety supervision department itself will cause a commotion.

Therefore, Xu Qing feels that there is a high probability that the conclusion of the Ministry of Safety Supervision will be "on the facts", and there are regulations to follow, so why make trouble for yourself?

Of course, it is not excluded that there are people in the Ministry of Safety Supervision who are really willing to think about Shi Zhonghao's problem, but in the face of the deep-rooted "old forces", I am afraid that they will not be able to set off any storms.

"Whether the safety supervision department accepts it or not is their business, and they can't change the idea that I think a single shot is more dangerous, even if I do it again, I still choose to interrupt." Shi Zhonghao said categorically, it seems that he is ready to be punished, and like Xu Qing's thoughts, Shi Zhonghao also feels that the Safety Supervision Department will not let him go.

According to the SOP, the interruption after 80 knots is engine failure, fire and windshear warnings, and other conditions that the captain believes affect flight safety. Brother Hao, can you make a fuss about the description of this other situation at the end? If the amount of oil in the engine is low, it will affect the safety of the flight? The co-pilot came up with his own thoughts, and he still wanted to find out the reason from the regulations to support Shi Zhonghao's interruption of the takeoff.

Xu Qing really remembered that there was such a sentence in the regulations, and at that time he wondered how such an ambiguous description could be added, and the other captains thought that the situation that affected flight safety was too large, and it was easy for people to take advantage of loopholes.

Unexpectedly, now they seem to be trying to survive by exploiting this loophole!

"It's useless, this passage is just that the company is unwilling to say it to death, and it can't be refuted by this passage." Shi Zhonghao immediately denied the co-pilot's idea: "This is for us to use this paragraph to exonerate ourselves, and as soon as this example is opened, the company will usher in endless trouble." The safety supervision department will not do such a thankless task! ”
