The Treasure Hunt of an Antique Dealer

"...This step seems cumbersome, but in fact it is normal and not bothersome, because the ground refueling staff at each airport are skilled in the conversion and can't make mistakes.

There is a problem!

The new Boeing 767 aircraft was used for commercial flight for the first time in December 1982. It uses \'kg\' to calculate the amount of fuel needed for the flight!

For example, a voyage needs to be filled with 10,000 kg of fuel. As a result, the buddy who is responsible for ground refueling at the stop airport is not familiar with this latest American-made large passenger plane. The number of fuel that needs to be refilled on the form is \'10000\' , Habits are converted into \'pounds\' used for many years of work habits.

The captain didn't check it carefully. After getting the refueling receipt given by the airport staff, he looked at it, and it was clear that there was a \'10000\ on it, and he thought it was OK. What's even more coincidental is that there was a small problem with the fuel gauge before, because the parts were sick to perform flight missions before they were delivered to the home port airport. As a result, the aircraft ran out of fuel halfway through the flight, but it was not visible on the fuel gauge."

Charlize Theron looked incredible: "This is also OK?!"

One pound is almost equal to 0.454 kilograms, which is less than a point. The ground fueler only added fuel to the aircraft less than half the actual value, which caused the aircraft to fly away!

What is this called!

When a lot of small problems got together by coincidence, it was fatal!

The imperial system and the metric system, who made the UK once the sun never sets, the whole world has been affected by it. For example, in China, the hammers are counted in "pounds".

Some things are okay in the imperial system, and in some places it is a lot of trouble: the FAL rifles that mercenaries like in the 70s and 80s also have different models used in the imperial and metric systems. They look exactly the same, but a bunch of parts cannot be interchanged , Fuck-egg!

There are also car speed dials. Some cars have two circles on the instrument panel inside and outside, one for miles and one for kilometers. People feel dizzy when you see them!

If you misread the speed limit sign on the ground, you will be fined, but it will be miserable in the sky! Zhang Nan still remembers one thing about the plane running out of fuel halfway, but it seems that the plane crash hasn't happened yet.

It should be more than ten years later that a twin-turboprop passenger jet jointly produced by France and Italy fell into the Mediterranean because of a new fuel gauge!

The fuel gauge that was originally installed on that aircraft had a problem. The pilot asked the company's ground maintenance staff to replace it with a new one. But the problem was that there were two small models of this aircraft. The aircraft was of type B, but it was replaced with an A. Type of fuel gauge.

The two pilots who were on the flight mission the next day arrived in the cockpit to make preparations before takeoff. They looked at the fuel gauge...

"Strange, why did you fuel up so early?"

Those people on the ground have become so diligent?

The fuel gauge showed that there were more than three tons of fuel in the fuel tank in the aircraft, but the cockpit could not find a refueling receipt left by the refueling staff.

Ask the tower: "Man, the gas is on. Where's the gas slip from the gas truck?"

The tower's buddies replied: "Can't find it?

It's okay, wait until you come back to make up your one. "

That note must be handed over to the company for accounting and filing.

The tower has said so, then fly.

The pilot of the Tunisian Airlines plane flew to Italy on the opposite side of the Mediterranean and was returning that day.

After arriving in Italy, the pilot looked at the fuel gauge and found that there were 1950 kilograms of fuel. The return airport was different and the distance was farther. To be on the safe side, the Italian airport was asked to add another 400 kilograms of fuel, enough to go home.

Go back home happily, less than halfway...

I fell into the sea, but at that time the fuel gauge showed that there were still 1,800 kg of fuel in the plane!

In the last investigation, the airport in Tunisia did not refuel the plane at all that morning, and the tower pitted the pilots!

The pilots themselves made a little mistake and did not follow the rules strictly: Ask the ground service refueling department for the refueling receipt!

The most terrible thing is that brand new fuel gauge!

The A-type fuel gauges of the same size can be installed on the B-type aircraft, and there is only a small set of numbers on the shell: for example, one labeled "2500" and the other labeled "2250".

The consequence is: even if there is not a little bit of fuel in that plane, because the sensor in the fuel tank is not matched, the fuel gauge will show that there is still 1800 kg of fuel!

So when the hapless plane left Italy for the return trip, the pilots thought that there was 2,350 kilograms of fuel in the plane, but in fact there was only a poor 550 kilograms!

The problems on this plane are all sorts of strange, anyway, Zhang Nan is a bit panicked, so whether it is his private fleet or private airport, this management method not only uses the civil aviation system, but also applies some appropriate air force regulations.

Nothing can go wrong in any link!

I suspiciously give you the highest salary in the industry, and you have to show the most dedicated attitude!

...

There was news in the morning news in the morning of the next day: the host broadcast the judgement of several American private jet pilots, and some people did experiments with the Airbus A320 flight simulator.

The speed is very fast, because Mike and others answered the phone call yesterday at the pilot’s apartment restaurant in Bordeaux Airport, and Zhang Nan said that they should contact them.

Other pilots from all over the world who were also in the apartment did not know that Zhang Nan discovered this situation, but the news spread extremely fast, and by dawn, many large international media and airlines knew it!

In particular, companies using autopilots of the same model as the A320 are even more concerned. During the night, more than one company did a test.

The result is that "3.3 degrees" has become "11 degrees"!

There are also post-mortems: the unnamed pilots of two airlines revealed that they had also encountered such a problem. When the plane was landing, a cloud layer appeared, and it turned out that the altitude was much lower than expected!

Fortunately, they still have a high degree. After switching to manual driving, they avoided the danger, but even if they did not understand the reason, the company did not pay attention.

The pilots themselves were unable to concentrate at the time and were embarrassed to speak too clearly.

The Air France A320 was not so lucky, it lost its height and hit the mountain!

Okay, Mike and the others stepped on Airbus so hard that they also gave Boeing a wake-up call, but generally speaking, Airbus and Air France in Europe will have a headache~www.readwn.com~Boeing still laughs haha: In the morning when Zhang Nan led someone to dig the second burial site, Boeing's sales department even called a thank you call.

Simply, Zhang Nan is their high-quality customer. Not only does he use private jets made by Boeing, but he is also a major shareholder of American Airlines. His pilot discovered this safety hazard. Of course, it is a good opportunity to get in touch with each other.

Instead of paying attention to the troubled Frenchman, he focused on digging: the pit was not big, and it was a wooden box that was basically rotten.

The box was originally very thick and there were a lot of wooden boards left. The contents inside did not disappoint Zhang Nan: a pile of crowns, and an item wrapped in a thick and unidentified substance.

Zhang Nan ignored the crown first, and after taking out the object about 50 by 40 by 16 cm in length, width and height, he said with emotion: "Unexpectedly, Europe in the Middle Ages also understood this method."

"what is this?"

Ajani asked when she looked at this big, brown, impervious mortar on the outside.

"This is the book!"
