I'll see! Instructor Chang waited for a while, and found that the plane only lowered its head briefly, and there was no more action after that, so he breathed a sigh of relief and said with a smile: "I'm too careful." ”

Xu Qing realized that it should only be a short-term correction of the aircraft due to unstable air currents, and the aircraft has been running stably since then. Xu Qing was curious why Teacher Chang was so nervous just now.

The plane is still below 10,000 feet, and it is in the critical stage of flight, and I am afraid that I can't say a word or two clearly from the appearance of the instructor. He didn't want to talk to Instructor Chang for a long time about the strange situation just now during the climb stage, so he simply waited for the cruise to discuss it in detail.

Teacher Chang obviously had this plan too, and did not take the initiative to tell Xu Qing the reason for the overreaction just now.

After waiting for the plane to stabilize at 8,900 meters, Xu Qing couldn't hold back the doubts in his heart and asked Instructor Chang about what happened just now.

Why are instructors so sensitive to airplanes bowing their heads?

"Hahaha, it's not that this broken plane is equipped with a maneuvering feature enhancement system, MCAS system, it seems to be this ......" Instructor Chang saw that the plane had entered a stable cruise, stretched his waist, nestled in the seat, and said leisurely: "It's all some novelty." ”

"What do you mean, I didn't understand it during the training?" Xu Qing wondered.

Teacher Chang: "I just mentioned it, and then I didn't follow it, maybe it didn't matter much!" After all, there are so many aircraft systems, and we can't know everything in detail. ”

Xu Qing loosened the seat belt electric door, also found a comfortable position, and replied: "We should always let us know something new." ”

"Then you should go to work as a mechanic, hehe." Instructor Chang smiled: "If you want to know how to open it, and you need to know how all systems run, you can go to the maintenance side to work part-time and get double salary." ”

Xu Qing was also happy: "What if something goes wrong with the new system?" You can't be ignorant! ”

"Boeing must have considered it, if this system really has a huge impact, there will be special instructions in the training course, how can it be lightly brushed aside." Teacher Chang said: "When the manpower is exhausted, don't keep picking and become like Chen Datou." ”

Chen Datou is Chen Yi, and when teachers often ridicule Chen Yi, they like to talk about his big head.

"So you were so nervous?" Xu Qing laughed.

Instructor Chang said lightly, wasn't he nervous when the plane bowed his head just now?

Teacher Chang pouted: "Be careful with new things, stress reaction, stress reaction...... Don't worry too much about it. ”

MAX is a new gadget after all, unlike the 700 or 800, how many years have it been flying, it is already like an arm, and there is no panic when something goes wrong.

What kind of special reaction does MAX have, he should still be polite and panic if he is reasonable!

Looking at the stiff style of the regular instructor's dead duck, Xu Qing smiled.

He still believes that Boeing can't hide certain systems that will have a significant impact. Instructor Chang is just an old pilot, always vigilant enough.

Boeing has always been known for its rigor, and it stands to reason that it does have a clear sense of priority, and if the maneuverability enhancement system is really important, Boeing will definitely make a special statement to the pilots.

Looking back now, it seems that during the theoretical training, the theoretical instructor did not seem to talk about the maneuvering characteristic enhancement system. The two sides confirmed that the so-called maneuvering feature enhancement system should not be an important part.

However, the Boeing company, which Xu Qing has always trusted, overturned on this plane!

"How does the Maneuvering Characteristics Augmentation System get the nose down? Trim, horizontal stabilizer? Xu Qinghao studied hard, and since he heard something he didn't know, he was ready to break the casserole and ask to the end.

Xu Qing's inquisitive spirit embarrassed Teacher Chang: "Let's match it...... I remember it was! I just glanced at it casually, and I easily couldn't answer if you asked me so much. Wouldn't it be embarrassing if I asked? Take it easy......"

"The change in the aerodynamic layout of the MAX causes it to produce a head-up moment at high speeds, which increases the risk of stalling, so this system allows the aircraft to lower its head to reduce the angle of attack when it detects a larger angle of attack to avoid stalling." Teacher Chang said: "In the final analysis, it is still a lack of static stability. The old shell of 737 doesn't seem to be very suitable for MAX. ”

When Xu Qing listened to Teacher Chang's words, he had already begun to flip through the MAX e-manual.

He searched the e-manual using MCAS and Maneuvering Characteristics Augmentation System as keywords, and found only a few descriptions.

Judging by the Boeing manual, this system really seems irrelevant.

Xu Qing went through all the descriptions of the maneuvering characteristic enhancement system, and all of them added up to less than ten sentences, and he read them all in a few glances.

Xu Qing reluctantly closed the electronic manual and didn't take this matter to heart.

……

After Xu Qing flew a few classes of MAX with Instructor Chang, he basically figured out the difference in the handling of MAX, and the speed of acceptance was quite fast.

After a few flights, Xu Qing felt that the 737MAX was a good aircraft.

However, it didn't take long...... He will know how naïve he is!

……

As usual, the morning shift, the captain is still a regular instructor, Xu Qing took a seat, and a pair sat in the back as an observer.

After the sleepy-eyed Xu Qing asked the purser for a hot towel to put on his face, Instructor Chang just went around the plane to check the cockpit and came in.

After Instructor Chang sat down, Xu Qing, who was awake and dozing, said to Instructor Chang: "The plane in front seems to have reported an error in short-term jittering. ”

Teacher Chang nodded: "I read the record, the company called just now and said that it has been repaired, it's fine!" ”

Xu Qing didn't care, there will be some problems with the aircraft from time to time, and the maintenance will be maintained and debugged in accordance with the regulations, which have strict rules and regulations, and Xu Qing can still be trusted.

Telling Instructor Chang that there had been a mistake before, it was just a routine report, Xu Qing didn't take it to heart, and continued to prepare for the plane.

After that, the flight was launched, drove, and taxied out as usual, Xu Qing didn't feel any difference in this flight until the plane was allowed to take off......

The weather is good today, and Xu Qing has been maintaining manual control after the plane takes off, ready to practice more by himself. This kind of co-pilot manual manipulation practice is normal, and the instructor does not stop it.

As the speed rate retracted, Instructor Chang found that the red and black speed band below his side felt a little problematic, and it was very close to the current airspeed, and it looked like it was about to stall.

At this time, the regular instructor just put the flaps on. During this period, he paid attention to the state of the plane and everything was normal, so he wondered if there was a problem with which sensor, so he was ready to look at the speed band on Xu Qing's side.

At this moment, the flaps were closed, the transition lights went out, and an uncontrollable furious beast closed the flaps...... Wake up!
