Relying on the positioning system as the only navigation guide, the modified 737 began to slide out in strict accordance with the predetermined route at the moment of starting the engine, and the positioning point of the navigation module was in front of the middle of the aircraft, so the center line of the aircraft has been consistent with the center line of the connection line, when the plane began to slide, all the lights in the airport were extinguished in an instant, and even the lights on the nose were turned off by Zhang Wenhao, the cockpit was brightly lit, and it was dark outside, so everyone looked out inside the plane and could only see themselvesOther than that, everything outside was shrouded in darkness and unrecognizable.

If it is in this visibility, it is not said that it is a civil aircraft, and even military aircraft cannot take off at all, because now the pilot's visual distance is equal to zero, and there is no way to know everything outside, and even they can't find where the runway is, however, with the assistance of the Dongchen positioning system, the aircraft is extremely clear about the set route, even if there is no visibility outside, but, through the image simulated by the large screen of the positioning system, the position and speed of the aircraft at this moment are extremely clear!

On the screen, the airport runway is displayed in the form of a floor plan, and the aircraft itself is not a simple positioning highlight, but represented by a year-on-year reduction of the 737 simulation map, simulating the aircraft's every move at this time, and because it is a year-on-year reduction, it is equivalent to a real-time thumbnail.

A group of people crowded to watch the display screen of the positioning system, and Director Liu said: "The next corner will enter the runway?" ”

Zhang Wenhao nodded and said, "Enter the runway, and the plane will start to accelerate at the center line." When it comes to lifting the speed of the front wheels. The flaps are automatically adjusted for take-off. ”

An expert next to him said with some concern: "Once the plane doesn't really find the runway." Or a few degrees off, without the runway to start accelerating, once out of the runway, we are finished, in addition, once the decisive speed is reached, if the plane has a slight deviation in the direction or the plane does not take off automatically, then we people are more than lucky. ”

Zhang Wenhao said indifferently: "Since Dongchen is ready to launch this technology. It must be a mature technology, and as you know, Dongchen has now begun to acquire Airbus, do you think that if Dongchen does not have a few high-end technologies like killer features, it will go to great lengths to acquire Airbus? ”

As soon as Zhang Wenhao's words came out, everyone woke up one after another, yes, Dongchen has long been planning to acquire Airbus. And without leading core technology, they will not set their sights on this industry at all.

Meanwhile. The people on the plane also clearly felt that the plane was also starting to turn.

Zhang Wenhao said: "Everyone go back to their seats and sit down, there is a real-time video in the cabin, and you can see everything in the cockpit." ”

When everyone heard this, they hurried back to the cabin, and after the plane had completed the turn, it waited at the end of the runway for a full five minutes, and when the time of five minutes was up, the sound of the plane's engine suddenly increased, and the engine began to fully exert its strength and prepare to speed up and taxi.

Everyone doesn't know where the plane is now, can't see the runway, can't see anything, can only pray in their hearts that everything is okay, and once the take-off of the plane reaches the decisive speed, at this time, the plane has no way back, can only take off, even the runway can not meet the distance that the plane stops from the decisive speed, so in this case, even if the plane suddenly catches fire, the plane must take off, go to the sky first, and then find a way to land.

Although they can't see the outside and can't feel the speed of the plane at this moment, they can also feel that the speed of the plane is getting faster and faster from the stronger and stronger sense of turbulence.

“V1！ V1！ ”

The cold computer prompt sounded throughout the cabin, the plane had reached the V1 decision speed, and an expert who knew something about civil aviation said: "Okay, if it doesn't stop at V1, we can only take off, and leave it to fate." ”

As soon as the words fell, everyone clearly felt that the nose of the plane began to rise, and the plane took off!

A completely unmanned aircraft, it stands to reason that an unmanned aircraft is naturally not qualified to carry people, after all, this thing leaves people, and no one thinks it will be really reliable.

The plane has begun to climb, everything is the same as the normal feeling of taking a plane, if it is not for the fact that there is not even a ghost in the cockpit, everyone will not have any special different feelings, and the plane began to follow the established route in the sky, around the airport value of a five-side, and then the last side flew by, the plane turned, began to prepare for landing.

Everyone saw the distance of the plane from the runway at this moment, the altitude of the plane at this moment and the descent rate, everything seemed to be very normal, and the altitude of the plane was constantly decreasing, and the distance from the runway was also being shortened.

A series of preparations for landing are automatically completed by the aircraft, the flaps are opened, the engine thrust is reduced, the altitude of the aircraft is steadily reduced, and after a few minutes, the rear wheels of the aircraft have a clear feeling of touching the ground, and then, the front wheels touch the ground, and the speed of the aircraft quickly decreases, which makes everyone breathe a sigh of relief.

However, after the plane landed, taxiing out of the runway and returning to the parking stand is still autopilot, and the position of the aircraft returning to the parking position is exactly the same as the position before the plane took off.

For the staff outside the airport, this unmanned test flight is extremely successful, before the aircraft takes off, the position of the front and rear landing gear has been marked by the staff on the ground with white edges, and the plane comes back, it is still parked in the drawn sideline, the staff outside are the backbone of Dongchen Aviation Engineering, they have already known that Zhang Wenhao will start to produce Dongchen's own passenger aircraft after completing the acquisition of Airbus, and now, such a powerful positioning system, It has become the most accurate guidance system in human history, and if Dongchen's future aircraft will have this unmanned capability, it will be enough to change the development and process of the entire civil aviation industry.

However, Zhang Wenhao also knows in his heart that if a super biochip like a super learning system is not developed. Then a computer can never be compared to a person. This kind of autonomous driving system. Although it seems that the accuracy is far beyond the limits of human beings, in the future, when Dongchen develops its own aircraft, it must not abandon the necessary factor of pilots, and it is impossible for Dongchen to really develop unmanned passenger models, and in the event of any emergency, the adaptability of the human brain is almost far superior to that of computers. What's more, humans still have the ability that computers don't have, and that's the role of experience.

However, even if it is impossible to abandon the important factor of manual participation in the short term, this system is enough to make Dongchen's future passenger aircraft stand out, if powerful and precise navigation, in any airport, in any visibility, Dongchen's passenger aircraft can easily take off and land, and one day in the future, perhaps Dongchen's passenger aircraft will be shuttled on the world's air transport lines with Boeing, Airbus and other aircraft with a huge number of aircraft. At that time, the following scenarios are likely to occur.

First of all. Once Yanjing enters the foggy state and the airport is closed, then all Airbus and Boeing planes will temporarily choose other airports in the surrounding cities for alternate landing, however, Dongchen aircraft only needs to turn on the autopilot and call up the data of a runway at Yanjing Airport, and the aircraft can easily land automatically without a field of vision.

In addition, if one day, Yanjing is affected by heavy fog, even the outbound flights are forced to stop, tens of thousands of passengers stranded at the airport, only Dongchen aircraft can obtain the airport tower take-off permit, in this way, the world's airlines will find a problem, if equipped with Dongchen aircraft, their costs can be further reduced.

At that time, the work of air traffic control will be much easier, every time a plane is allowed to land, they only need to send the runway data to each other, so that they can land quickly and safely in strict accordance with their own requirements, and then quickly and safely enter their respective parking stands.

What's more, Zhang Wenhao's killer technology that he is ready to use on Dongchen's passenger plane is far more than this.

Once the positioning system of Dongchen is completed, even if it is not modified for automatic driving, the pilot can take off without line-of-sight according to the data given by the Dongchen positioning system, which will be epoch-making for Dongchen and the world.

When they saw that the wheels of the plane were reattached to the previous sideline and seemed to have never moved, they all showed surprise on their faces.

The experts of Beidou finally know what it means to be self-conscious this time, Dongchen has done what they have done in the past 20 years in a month, and it has benefited countless times more than them, Dongchen's technology has been proud of the positioning system in the whole world.

After getting off the plane, an engineer from Beidou asked with a look of surprise and humility: "Mr. Zhang, I would like to ask, Dongchen has developed so many sets of terminal equipment for this positioning system, what are the main differences?" Is it necessary castration on a portable mobile device? ”

Zhang Wenhao shook his head and said: "We will not deliberately be strict about the functions and performance of the product, for example, the mobile phone module of the Dongchen positioning system can also achieve three-dimensional navigation, however, because of its weak processing power, his performance and function are far less than the on-board positioning module, so it does not have the function of 3D simulation, nor does it have too many computing auxiliary functions, however, in the face of the continuous improvement of the terminal, we have added a large screen and a more powerful dual processing chip on the handheld terminal. Therefore, the function and performance of professional handheld terminals are much more than those of mobile phone modules. ”

In the future, the functions of automatic driving and no-line-of-sight take-off and landing will also be directly transplanted to Dongchen's large passenger aircraft, becoming the standard function of Dongchen Technology."

"Standard features?" The man was stunned for a moment, and said: "Then I think, you should submit this system to the International Civil Aviation Administration for approval as soon as possible, if they recognize the efficacy of this system, this system can really enter practical application, if they do not recognize this system, they will use hard requirements, force Dongchen passenger aircraft to be the same as other passenger aircraft, if the visibility of a certain airport does not meet the previous landing standards, even if the Dongchen passenger plane has the ability to land, it is useless, can only obediently choose to alternate landing." ”

Zhang Wenhao smiled secretly in his heart, the International Civil Aviation Authority? Once Dongchen's new technology is applied to the new model, then the International Civil Aviation Administration will give airworthiness and applicable standards in the shortest possible time, perhaps one day in the future, all aircraft will be required to carry out such modifications, but Zhang Wenhao has already made up his mind, once he successfully acquires Airbus, then he will carry out absolute technology exclusivity, Boeing will not get Dongchen's engine at that time, let alone such a system.

At this time, he asked Zhang Wenhao: "Wenhao, you must keep an eye on foreign launch plans, if today's test results are known to Western countries, I think the vast majority of them will refuse to launch rockets for Dongchen."

Zhang Wenhao smiled slightly, and said: "Don't worry about this, all the employees present at Dongchen tonight are very reliable, and our overseas launch plan has been successfully negotiated, and the launch will be completed in just one month.

This set of Dongchen positioning system is of great significance to Zhang Wenhao, Zhang Wenhao is even planning, quickly transplant this system to Dongchen car, in the future, all the official standard models with navigation function, central control color screen, will be Dongchen's navigation system as a replacement, the front upgrade of the existing navigation module, by that time the traditional GPS navigation will enter the strange road! What's more, Zhang Wenhao has the technology of large-capacity, high-speed flash memory particles, coupled with the omnipotent Xiao Er, he can even map the most accurate and detailed world map in a short period of time, so as to facilitate Dongchen car users all over the world.
