What is the most feared situation in unfamiliar airspace? Especially during the long-distance voyage without the store and the village.

Undoubtedly, a Trek.

The 2238325 H-6KZZ got lost.

This is not the first difficulty encountered, but it is a rather serious situation.

With the blessing of modern aviation technology, Trek is basically non-existent, and there are many ways to navigate alone, including visual positioning, geometric positioning and dead reckoning. In order to find the right direction, the aircraft must first determine its own position, and these three ways are to solve this problem.

The crew lost contact with the rear command post half an hour ago, and at the same time, some related instruments encountered strong interference, causing large deviations in the data, and some electronic equipment also encountered interference, the more serious one was the air data system and the automatic pilot. Liu Changxi has a wealth of flying experience, and he can see at a glance that the data is very biased.

According to the calculation of the time and speed of the flight, it was already 1,500 kilometers away from the mainland at this time, and was entering the hinterland of the western space domain in a broad sense. Nature is mysterious, and there are many places where some phenomena cannot be reasonably explained by current science and technology, such as the famous Bermuda Triangle, where many planes and ships have been recorded to crash and sink inexplicably. Airplanes and ships have all failed to function in their electronic tracks, and we know that this is a phenomenon caused by the extremely strong interference of the earth's magnetic field, but there is still no convincing analysis of so many aspects.

At this point, it was as if the plane had flown into an area similar to the Bermuda Triangle.

A notification has been sent from the technical team, and it can be confirmed that the aircraft has been strongly interfered with.

However, before the departure of the crew, it was carefully prepared for several months, and dozens of sets of plans to deal with various situations were drawn up, with more than 100 emergency handling methods and danger handling plans, and the airspace through which it passed was studied and analyzed.

The crew and technical crew were not randomly formed, and the radio communicators and navigators that Li Zhan had never seen since he got on the plane were all responsible persons of the operational departments of the independent reconnaissance regiment, and they were all backbone personnel with extremely capable abilities in a certain aspect. For example, the chief of the unit, who acted as a radio communicator, was himself a senior radio technician, and he was able to deal with most of the possible failures of the radio system on the aircraft. The chief of navigation personally served as the navigator of this operation because he was the most experienced in the living charts of the independent reconnaissance group, and had gone out to sea with the ocean-going formations of the navy.

Even the three members of the entourage were not determined casually. In the case of Yu Chenglin as the commander of the Fourth Regiment, his other identity is still an aviation mechanic, which even Li Zhan does not know. And Zhang Wei is actually an aviation armory, and he has relevant qualifications.

Among the eleven people, Li Zhan was the only one who didn't have this certificate, and that certificate didn't have any specific ability, so he served as the head of the discipline team, managing discipline and helping to make radio contact. However, he was the most important of the eleven, and he was the only one who asked to participate in the operation by name.

The fundamental reason is that Li Zhan has unparalleled experience in handling dangerous situations, and he is an encyclopedia of dangerous situations. But there is another superstitious view that this person is unlucky and unfit to participate in such an important action, and it is clear that this superstitious view has no market and must be spurned.

Liu Changxi once said that he invited Li Zhan to participate in this operation because Li Zhan's reconnaissance plane was very experienced in using it, but in fact, he was afraid that he would embarrass Li Zhan by saying it thoroughly, so he found such a reason. In fact, the difference between a strategic reconnaissance aircraft unit and a tactical reconnaissance aircraft unit is quite large.

The staffing is perfect and the technology is well prepared, so there is no panic about the current situation.

Liu Changxi reduced the airspeed to 650 kilometers per hour, the course and altitude were not adjusted, and after handing over the control of the plane to Bai Bitu, he turned sideways and studied it in a low voice with Li Zhan.

There is no reference object at night, it is an unfamiliar airspace, there are no navigation points, no landmarks, and no ground radio facilities to provide support, which means that visual positioning and geometric positioning are not feasible, and dead reckoning can only be carried out.

Li Zhan quickly took out the calculation results and pointed them to Liu Changxi, "According to the calculation of our course speed, it should be this status at present, that is, ......."

He circled the location in the chart, "Here, the interval between 180 kilometers and 200 kilometers southeast of Kaidao, the specific coordinates should be ......."

After Li Zhan wrote out a coordinate number, he changed his words and said, "But we didn't notice the electromagnetic interference until half an hour later, which means that the plane was very likely to fly under the guidance of an autopilot with a large error in the half hour before the problem was discovered." The technical team is calculating the deviation value law, and needs to wait for their specific numbers to come out in order to calculate the results as accurately as possible. ”

The aircraft is on autopilot all the way after entering the cruising state, and the autopilot and autopilot work together, and the pilot only needs to set the key parameters and the aircraft will automatically fly to the destination. By the time of the K model, this grandfather-class medium and long-range bomber already had the flight control system of a modern airliner. Generally speaking, many subsystems of modern aircraft have multiple sets, and if one set is broken, there will be a second, a third or even a fourth set, and the possibility of all failures is extremely low.

Xie Xinyu ran over and reported in a low voice, "It's full-range interference, and the power is very high, which has exceeded our anti-interference ability." We are tracking the source of interference, but our technical team does not have the means to give effective advice on the flight. ”

In other words, until the source of interference is eliminated, the technical team will not be able to guide the crew in an effective direction, and of course, there will be no way to determine the specific location of the aircraft.

Li Zhan nodded slightly, "Got it." ”

Xie Xinyu's look of rejection from thousands of miles away made Xie Xinyu very uncomfortable, but this was an extraordinary period when she had no time to think about it, and it was even very likely that she had mixed some personal emotions into her work. Li Zhan, a combat pilot who is loved by everyone, is insensitive because he has encountered too much, and he has already clearly distinguished between personal emotions and work, and will never change his attitude because the other party is a big wave of tall and beautiful women.

No one can shake his indomitable strong nerves for building a strong people's air force.

It seems to be expected to be strongly interfered with, including Liu Changxi, who is also mentally prepared. The flight plan was about 200 kilometers southeast of Kaidao, and there was a possibility of strong interference.

After all, nature is mysterious and difficult to figure out.

In this completely unfamiliar airspace for the Chinese Air Force, there are no flight parameters to refer to, they are actually opening up a new route, a route belonging to the Chinese Air Force, and in the future, more fighters will use the relevant parameter data they get to guide flight training along the route they flew out.

Li Zhan and the others were fully mentally prepared, and those who participated in this operation were mentally prepared to sacrifice their lives.

Sacrifice is the easiest thing to do, and the hardest thing is to successfully complete the task and bring back the proceeds of this trip.

It is necessary to confirm the position of the aircraft as soon as possible and return to the planned route, otherwise the aircraft will not be able to fly back to the mainland due to excessive unplanned consumption of fuel.
