The Treasure Hunt of an Antique Dealer

There was a TV in the canteen, which was on, which happened to be a news program, but Zhang Nan couldn't understand the French spoken in it.

Because the content of the news seemed to be an air crash, I was a little interested in seeing it, so he motioned to the butler Tom to increase the volume, and by the way, I asked Ajani what the news was talking about.

I often take a plane to fly around the earth, and this kind of flying 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 and crashed when it landed. Several people miraculously Survived, a total of 87 people were killed, very miserable!

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

Ajani listened and translated, "...The black box of the call recorder in the cabin showed that the captain and the co-pilot said that he set the descent angle on the autopilot to 3.3 degrees, but the radar showed that the plane was actually Up is going down at an 11-degree dive angle, which puzzles investigators very much."

At this moment, Ajani said that Zhang Nan was planning to drink a glass of Lusalus noble rot wine as a drink. After listening to this simultaneous translation, the wine glass was left in his mouth for a long time, neither drinking nor putting it down.

Paul, who was dining nearby at the same time, saw this state, his hands slightly gestured on both sides, and the other voices in the restaurant and the clash of tableware during the meal were immediately gone, only Mrs. Adjani hanging on the wall with him. The sound from the TV.

Andre, sitting next to Paul, felt a little bit interesting about the situation-obviously not because the boss wanted to watch TV.

Sure enough, Paul on one side lowered his voice to him and said to him: "The boss is thinking, and something special will happen in all likelihood."

The Red Devil's deputy captain glanced at Paul, who made a "that's it" expression on his face.

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

After finishing the news, I put down the wine glass and took out the soft-shelled Zhonghua Point from my pocket.

Adjani by her side didn't stop Zhang Nan's bad habit, she was all used to it: her man's habit seems to be incapable of changing, but she is in control, and she has drunk less every day for the past two years.

He smoked half of it, put it out, and said, "Call Mike."

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

Mike, the first captain of his own 767 (his private jet has three sets of crew), there will be two groups of pilots in the aircraft for long-range flight.

Equipped with three groups of personnel, it is to prevent the boss from going far away when the pilots are on vacation, and it will be fun if the crew is not available.

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

The crew members were staying in an affiliated hotel of Bordeaux Airport, and the phone was connected soon.

Zhang Nan took the phone from Mark and said, "Mike, I’ll ask you a professional question... Yes, it’s about flying and airplanes.

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

The captain on the other end of the phone was also having a meal with three other pilots. Although he was wondering why the boss asked this question, he still answered all the questions raised by the boss in great detail.

The question is very professional. Some captain Mike needs to communicate with his colleagues to answer the boss accurately. There is a question that even made the four pilots a little bit afraid: they usually noticed the problem, but they can only say that they noticed. Because they are the best passenger airplane pilots.

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

After talking for a while, Zhang Nan finally said to the phone: "You know about the crash of the Air France flight number 20 in Strasbourg, right?

It's the 3.3 degree and 11 degree questions... You can ask the accident investigation committee's phone number at the airport, tell them where the problem is, and tell them that this is a brain-dead design and a horrible life!

...No, I don't want to be an expert, just say that you and your colleagues thought of it together.

That's it, hung up. "

As soon as the boss said this, it was the final decision and there was no discussion.

When I hung up the phone, I saw that everyone else in the restaurant was basically looking at me. Adjani and Charlize Theron next to me were already staring in their eyes, and they were surprised and admired!

It's worship, the phone call just broke!

"What are you looking at?

What's weird.

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

The autopilot should be used on both sides, it is very advanced, there are two modes when the plane descends before landing.

One is to input the angle, such as 3.3 degrees, and the small display screen will display ‘—3.3’;

The second mode is to input "How many feet per minute fall", because the display is narrow and narrow, and it is very short. In this mode, if the input is "Descent 3300 feet per minute", you only need to enter '33', because the aircraft If you can't fall 100 feet in one 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 little ant's head. The design is professional and deceptive!

Unfortunately, the captain who had gone to see God probably forgot to switch the autopilot mode when it was descent. He wanted to enter an angle of 3.3. Because of the mode, he actually entered ‘drop 3300 feet per minute’.

The difference between the two is a very inconspicuous little pause, and neither the captain nor the co-pilot noticed that the data entered was wrong!

If those accident investigators went to calculate and simulate, 3300 feet per minute, plus the speed at that time, the hapless plane should be descending at a dive angle of 11 degrees~www.readwn.com~ That’s it, I understand. Yet? "

After speaking, Charlize Theron and the three Red Devils clapped together!

This caused other people to stand up and applaud. Zhang Nan had to stand up and clasp his fists to greet everyone, and everyone settled down.

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

With such analytical skills, you can become a judge after training.

However, some people smiled in their hearts: Those who have followed Zhang Nan the longest know that there must be other problems here, because the boss's math score is absolutely bad!

Zhang Nan absolutely can't figure out the relationship between "descent 3300 feet per minute, speed and angle", that is meaningless to him, and it is like a book of knowledge!

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