Coquettish Rebirth

Jia Hongjian and the others wanted to refit their planes. Of course, it didn't mean that the four planes had to be sent together for refitting, but they would come one by one.In this way, if Jia Hongjian was going on a business trip here, it wouldn't mean that he didn't have a plane to use.After the general discussion here, Lao Song and the others will need about a month to carry out design and check calculations to see how much modification the aircraft will undergo.

Here, after Jia Hongjian waited for Ye Jing and Celine Dion's special plane to pick him up, the group flew up to Shanghai again.But for this flight, Jia Hongjian did not sit in the cabin obediently. Instead, he ran into the cockpit to "harass" the pilot "rebelliously".Of course, this kind of "rebellious" and other evaluations are used on other civil aviation airliners, and the evaluation standards after 2001 are still used.

Why is it the evaluation standard after 2001?It was because of a 2001 incident in 911!Before the 911/[-] incident, not to mention China, even American civil aviation airliners, passengers could still enter the cockpit—of course, only when the captain nodded.At this time, the cockpit door on the plane is still a two-way door, that is to say, it can be opened in both directions. People outside can open the cockpit, and of course people inside the cockpit can also open the door.

But after 01, in order to prevent someone from hijacking the plane, the door of the cockpit was designed as a one-way switch. manage?Is there nothing I can do about flight attendants?All the people on the plane can only watch the pilot drive the plane into the building?So it is one-way, but it is actually two-way.It's just that if you open it from the outside, it is locked with an electronic combination lock.If you want to open the door outside and enter the cockpit, you need to enter the password.As for this password, most flight attendants will know it.

How did Jia Hongjian know about this?Because he happened to be in the first class once, and he sat very far in front, so he could see the door of the driver's cab through the kitchen aisle of the first class.He has also seen a flight attendant press the mentally retarded four-digit code "1234" and then open the cockpit door.Of course, Jia Hongjian would not casually tell others about such a simple password.

Now, Jia Hongjian came to the cockpit.It did not say that the pilot was delayed from flying the plane.the reason is simple.After the plane took off, it climbed to the cruising altitude, and then the plane began to fly automatically.At this time, the pilots did not have their hands on the "steering wheel". They were just chatting and paying attention to the instruments.It is just monitoring the automatic flight of the aircraft.Bosses like Jia Hongjian came in to chat with the pilots.The pilot was a little nervous though.But they can't do anything about it - from a certain extreme point of view, it's like a passenger talking to the driver, which is a little bit dangerous.And even more so with airplanes.Because the warning information on the plane is really inconspicuous. Maybe when the sun is shining in broad daylight, there will be a small green light the size of a fingernail in the middle of the vast number of instruments and indicators. This thing may be to warn that something is wrong with the plane.Of course, this must be a small problem, because if it is a big problem, the main warning system of the plane will be ringing loudly.

As for Jia Hongjian, he didn't come to chat with the pilot just because he had nothing to do. He was curious about the working principle of the aircraft's automatic navigation.I heard from Lao Song before that the automatic navigation of the plane does not use GPS at all, so he was curious!He used to think that the automatic flight of the plane was based on GPS!

"Civil aviation airliners basically don't rely on GPS, because how to say GPS, it's too unsafe to rely on them alone, and there have been related investments in navigation before. It seems that this GPS was launched in 94? And in 94 In the past, civil aviation navigation equipment has been deployed around the world, and it is also very useful, so there is no need to add GPS..." After speaking, the captain began to introduce the aircraft's automatic navigation system to Jia Hongjian, "Like It is our plane, which uses FMS, the flight management system of the United States. This automated flight system relies on several sets of navigation equipment to integrate automatic flight. For example, when we boarded the plane, we set and calibrated the inertial navigation system. Laser gyroscope, and then the flight state computer of the aircraft can measure the current position of our aircraft through the changes of our acceleration, pitch angle, time and flight attitude. Then there are VHF omnidirectional lines on our civil aviation routes The beacon station continuously transmits route information to us, so after the computer corrects the information transmitted by the beacon station, it can automatically calculate which altitude to fly and which attitude to fly is the most fuel-efficient, and then it can automatically fly..."

Hearing this, Jia Hongjian roughly nodded.Although the pilot didn’t say anything else, he still understood the meaning—to put it bluntly, before the launch of GPS, almost all the automated navigation equipment in the world had already been built. Wouldn’t it cost more to add another GPS? ?And with the existing equipment, the effect is not worse than GPS.Besides, the altitude and speed measured by GPS are not necessarily accurate, and they are definitely not as accurate as those measured by the aircraft's own wire altimeter and airspeed meter.Even if the speed they measured was accurate, it was ground speed, that is, speed relative to the ground, and the plane flies at airspeed—that is, speed relative to the air in front of it.Otherwise, even if the ground speed of the plane is very fast, the wind around the plane in the air is the same speed as the plane. If the wind is moving forward at high speed with the plane, the air is still relative to the plane, so how can the plane have lift? ah?Isn't it about to fall if there is no lift?And if the latitude and longitude provided by GPS, what is the use of this thing?If there is a beacon station and you fly according to the internationally set route, then it is impossible to say that you are too far away from the beacon station, so you can definitely know the longitude and latitude. Why do you need GPS to tell the aircraft its own longitude and latitude? [

But to be honest, Jia Hongjian still thinks this plane is awesome—before GPS came out, this kind of automatic navigation could think of so much.While feeling emotional, he noticed the dashboard in front of the two pilots.In front of the pilot, there is a dense variety of instrument panels, such as airspeed gauge, altimeter, aircraft attitude, and various buttons and small lights, and even the position between the two pilots. There's also a small screen and a row of keypads that look a bit like a calculator or something.

The co-pilot saw that Jia Hongjian paid attention to this thing, and introduced it with a smile: "This is our automatic navigation device. Our keyboard has letters on it just like a computer keyboard. Then we need to go to the location of the beacon and input the signal. Mark the 4-letter code, and the computer will automatically find the route and be navigated there..." Jia Hongjian leaned over to take a look, and sure enough there were a sequence of four-letter English letters written on the small screen.Probably this four-character English code is a navigation mark?Then just fly along the navigation mark, and then accept the navigation of the tower, just in case it gets lost?

But Jia Hongjian looked at the automatic navigation computer, and then looked up at the various mechanical instruments, large and small, on the dashboard. To be honest, a comparison feels like things from two eras.Jia Hongjian has seen photos of the interior of the f22f35 aircraft of later generations. In the cockpit of his f35, there is a large LCD "color TV" in front of the pilot. What kind of information is this color TV really? can be displayed.It can display the altitude here and the airspeed on the other side, and it can take out various aircraft attitudes, weapon selections, and even terrain matching. It looks so high-tech!And the aircraft dashboard in front of me looks too primitive, it still needs to be changed to be more advanced!

When the time comes to change it, the cockpit of this special plane will look similar to F22F35, how fashionable it is!correct!When he thought of this, Jia Hongjian suddenly remembered a design he had thought about before, that is to design the car like the cockpit of a fighter jet—that is to say, remove all the instruments and place them directly on the driver’s seat. Put a display screen in front of you to display various information, and then use the technology of the HU head-up diffraction display of the fighter jet to project the navigation information and the information of the car itself onto the windshield, so that the driving When the driver is driving, the eyes don't have to take off the windshield at all!

After thinking about this, Jia Hongjian suddenly remembered that these things should be developed now? GPS itself already exists, and if we don’t start doing things like digital maps in advance, do we have to wait for others to do them?As for the instrument panel, it is true that Huaxia Auto's low-end cars are not used, but it is impossible for Huaxia Auto to develop low-end cars for a lifetime!After Chery developed QQ for a few years, didn't they also start developing other models?

Originally, when Jia Hongjian was about to withdraw from Bujing 660, didn’t he just think that in the domestic auto market at that time, a few manufacturers had sold old models for more than ten years, and they didn’t know the aggressive market at all?In the auto market of later generations, there is one model a year, which is improved every year. As for China, Poussin has not changed it for many years, and Xiali has changed a sedan in the past ten years, what other models have been changed?Even the Bujing 660 itself has been out for several years now, and there is no new model design.

Huaxia Motor itself has a project that absorbs the 85 national car plan designed by the Soviet Union in 2000, but this project is also aimed at the civilian market for the time being, and it also uses diesel, and the price is relatively low.Why can't Huaxia Auto develop terminal civilian vehicles now?Chery's development is slow because they rely on QQ to make money, and they don't have other businesses to make a lot of money, but Huaxia Hi-Tech is different!
