There is a TV in the cafeteria, which is on, and it happens to be a news program, but Zhang Nan can't understand the French spoken inside.

Because the content of the news seemed to be an air crash, I was a little interested in watching it, so I motioned to Tom, the housekeeper, to increase the volume, and asked Adjani what the news was talking about.

I often fly all over the world by plane, and this kind of flight accident is the most taboo, but every time I see it in the news, I will unconsciously understand it.

"Ten days ago, on the night of the 20th, near the airport in Strasbourg, the capital of the northeastern Alsace region, an Air France Airbus 320 accidentally crashed into a mountain while landing, and several people miraculously survived, a total of 87 people were killed, very tragic!

The news said that the cause of the accident is still under further investigation, but it appears that during the descent before landing, the angle of descent of the plane was more than three times the normal descent value set by the pilot at the time..."

Adjani translated as she listened, "... The black box on the in-cabin call recorder showed that the captain and co-pilot had said that he had set the descent angle on the autopilot to 3.3 degrees, but the radar showed that the plane was actually going down at an 11-degree dive angle, much to the confusion of investigators. ”

Adjani said that at this time, Zhang Nan was about to drink a glass of Lysalus noble rot wine as a drink, listening to this simultaneous translation, but the wine glass was put to his mouth for a while, neither drank nor put it down.

Paul, who was dining nearby at the same time, saw this state and gestured his hands slightly on both sides, and the other sounds of talking in the dining room and the clashing of the tableware during the meal disappeared immediately, leaving only the sound of the TV set hung on the wall by Mrs. Adjani.

André sat next to Paul, feeling a little funny about the situation — obviously not because the boss wanted to watch TV.

Sure enough, Paul on the side lowered his voice to him and said to him: "The boss is thinking, there is a chance that something special will happen in the future." ”

The Red Devils vice-captain glanced at Paul, who made a "That's it" look on his face.

Every time the boss appears in this state, something strange must happen!

After the news was over, he put down his wine glass and took out the soft-shelled Chinese point from his pocket.

Adjani beside her didn't stop Zhang Nan's bad habit, and she got used to it: it seems that this habit of her own man can't be changed, but it's under control, and she has smoked less every day in the past two years.

Smoked half of it, extinguished it, and said, "Call Mike." ”

Naturally, someone would follow the boss's instructions, and Mark, who was sitting behind him, immediately took out his mobile phone and started making calls.

Mike, the first captain of his own 767 (his own private jet has three crews), has two groups of pilots rotating in the aircraft when flying long-haul.

Equipped with three groups of personnel, that is to prevent the boss from going out when a pilot is on vacation, and the result is not a complete crew, it is fun.

When flying across the Atlantic Ocean and the Pacific Ocean, there are two groups of pilots, and this Mike is there.

The crew was staying in an annexed hotel at Bordeaux airport and the phone was soon connected.

Zhang Nan took the phone from Mark's hand and said, "Mike, ask you a professional question... Yes, in terms of flying and airplanes.

Yes, when the aircraft descends in autopilot control, are there two modes to choose from on the autopilot?..."

The captain on the other end of the phone was also having dinner with the other three pilots, and although he wondered why the boss asked this question, he still answered all the questions raised by the boss in detail.

The questions were very professional, and some of them needed to communicate with their colleagues before they could answer the boss accurately, and there was one question that even made the four pilots a little afraid: they usually noticed the problem, but they could only say that they noticed, because they were the best passenger aircraft pilots.

But the four of them never thought that the small problem they would pay attention to would kill them at a critical moment!

After talking for a while, Zhang Nan finally said into the phone: "Do you know about the crash of the Air France plane in Strasbourg on the 20th?"

That's the 3.3 and 11 degree problem... You can ask the accident investigation committee at the airport what the phone number is, tell them what the problem is, and tell them that it's called brain-dead design!

... No, I don't want to be an expert, just say that you and your colleagues came up with it.

That's it, hanging. ”

As soon as the boss said this, it was the final decision, and it was not negotiable.

Hanging up the phone, I saw that everyone else in the restaurant was basically looking at me, and Adjani and Charlize Theron around me were already little stars in their eyes, and they were even surprised and worshipped!

It's worship, that phone call just now exploded!

"What do you see?

What's so strange.

In fact, our Boeing aircraft and Airbus aircraft have many parts in common, and the two aircraft manufacturing companies are two final assembly plants.

That autopilot should be used on both sides, it's advanced, and there are two modes when descending before the plane lands.

One is the input angle, such as 3.3 degrees, and the very small monitor screen will display '-3.3';

The second mode is to enter "how many feet per minute", because the display is narrow, and it is very short, if you enter "3300 feet per minute", you only need to enter "33", because if the plane can't descend 100 feet in a minute, it is not called a descent.

At this time, the number displayed on the display is '-33'.

The numbers are very small, -33 and -3.3, that point is probably not much bigger than the head of the little ant, professional pit people, brain-dead design!

Unfortunately, the captain who had gone to God probably forgot to change the mode when the autopilot descended, he wanted to enter an angle of 3.3, because of the mode, it was actually '3300 feet per minute'.

The difference between the two is an extremely inconspicuous Xiaoton, and neither the captain nor the co-pilot noticed that the data entered was wrong!

If the accident investigators had calculated that 3,300 feet per minute, combined with the speed at the time, the hapless plane would have been descending at an angle of 11 degrees.

That's it, got it?"

As soon as he finished speaking, Charlize Theron and the three Red Devils actually applauded together!

This caused other people to also get up and applaud, Zhang Nan had to get up and clasp his fists and salute each other, and everyone settled down.

The Red Devils really admire this boss, and after watching a piece of news, they found a big problem in the air crash: this kind of cross-industry analysis, which is the result of the combination of attention to the details of ordinary life and rigorous and divergent thinking!

With such analytical ability, you can become a researcher after training.

However, some people smiled in their hearts: those who have followed Zhang Nan for the longest time know that there must be other problems here, because the boss's math scores are absolutely rotten!

Zhang Nan would never be able to calculate the relationship between "3,300 feet per minute, speed and angle", it was meaningless to him, and it was like a book of knowledge!

No way, I didn't learn math well in middle school.
