A famous actor once said: Even a piece of toilet paper has its use.

From the theory of objective idealism, the existence of anything has its necessity and logic for its existence, but it does not mean that there is a rationality for existence, such as criminals. To see the existence of something, it is usually necessary to consider the context in which reality is located, and it is generally believed that things that appear in the trajectory of historical development are inevitable, such as war, but it does not mean that war is reasonable.

With regard to the upgrading of weapons and equipment, we can generally believe that the existence or significance of the existence of second-generation aircraft cannot be denied just because they are inferior to third-generation aircraft. More specifically, the fact that the J-11 can't beat the J-10 does not mean that the former has lost its meaning of existence and its logic.

From the perspective of national defense strategy, both J-11 and J-10 are important components of national defense forces in the context of the current era, and they have their own tactical tasks.

However, it cannot be simply assumed that the two are not comparable.

As Li Zhan believes, from the perspective of subjective idealism, there will inevitably be a situation where the J-11 meets the F-16 in the future, and the J-11 must defeat the F-16. Just as there must be a war between China and the United States, when the contradictions are irreconcilable, it is not known whether the war will be 50 or 100 years from now.

As soldiers, what Li Zhan should do and can do is to constantly enhance his own combat effectiveness and be ready to fight the enemy and annihilate all invading enemies in order to defend the sovereignty, unity, and integrity of the motherland's territory.

Based on these considerations, Li Zhan valued the tactical methods derived from the confrontation and related thinking. From this point of view, the upcoming confrontation drills with friendly forces are of great significance.

After three days of confrontation and joint training, the exchange pilot group composed of Li Zhan, Chen Fei, Han Hongjun, and Li Zixin achieved the goal of enhancing the tacit understanding between them.

On the last day of January 2012, the ninth day of the Lunar New Year, the order required the military exchange group to take off at 10:30 a.m. At 8 o'clock Beijing time, it was already dark in the eastern region, but the area where the Duda station is located was still in the darkness before dawn.

Li Zhan and the other four pilots got up as required and immediately began to sort out their personal belongings and the items they needed to carry. It is a standard handbag, and it is soft and large. The relevant items and items that need to be used by the superior in accordance with the regulations, but even personal items are also required, and the superior has a detailed list to distribute, and items outside the list are not allowed to be carried, such as gadgets such as ear pickers.

Guo Beimu accompanied the department chiefs of the relevant departments of the military region who made a special trip to inspect the bags of the four pilots and check their clothing. As detailed as whether the edges of the armband fit are perfectly aligned, the degree of detail is that I can't even count the hair.

This kind of inspection is accustomed to those who serve as soldiers.

When it came time to inspect the guns he carried, the department chief was particularly serious, and after repeatedly checking one by one to confirm that there were no live ammunition and no faults, he watched Li Zhan and the others put them into the fast gun holster on their waists and buckle them. From the moment the button is fastened, the gun can no longer be used.

This military exchange has a coordinated exercise mission, so the pilots are required to set off in combat attire, and since it is a combat attire, it must be strictly carried out in accordance with the requirements of combat attire. You can't say that because you want to leave the country, you don't wear a gun, there is no such provision in the disciplinary regulations.

Of course, live ammunition is not allowed.

After the completion of these tasks, all members of the military exchange group gathered in the flight briefing room, and a working group jointly formed by the military and civilian inspection and quarantine departments was already waiting to begin the inspection and quarantine of all the members of the military exchange group. After completing this link, the members of the military exchange group cannot move around at will, and must follow the process to go to the next level.

When they return to China a few days later, they also have to go through such a process, especially inspection and quarantine, in case they accidentally bring back viruses from abroad.

For people who have gone abroad for exchanges, this process is very familiar, and it is similar every time, in fact, it is no different from ordinary people traveling abroad for business.

Except for Li Zhan and the other four pilots, the rest of them all flew to Start Air Base by Y-8, and this kind of maneuvering method has also been commonly used in all previous exercises with friendly forces, and there is a very mature liaison mechanism to ensure smooth operation.

According to the arrangement, Li Zhan led three J-11B escort Y-8s to the city. In view of this, all J-11Bs took off with full fuel, and the Y-8 was also fully fueled in addition to carrying the necessary equipment and equipment. They can fly 4,000 kilometers in one breath and reach the maximum transition radius.

After the Y-8 skied for more than 2,000 meters, it pulled up and left the land, and until it climbed to 6,000 meters, Li Zhancai led three J-11Bs to take off in a two-plane formation and rushed to join the Y-8 and form a formation.

The formation flew at an altitude of 6,000 meters, and the Everest mountain range in the southwest was even higher than their flight altitude, and it looked like a wall blocking it from the air.

Ra Zhi gave the order to climb to 7,000 meters, and the formation climbed steadily to 7,000 meters and flew towards the last navigation station. As we all know, the navigation station is an important guarantee for aircraft navigation. Put simply, a ground navigation station is like a combination of route signs, road signs, and signage on the highway, and its purpose is to provide a reference for the aircraft – to let the pilot know where he is.

Generally speaking, the well-known navigation station is the airport navigation station, which is often called the long-distance navigation station and the short-range navigation station, which is an important auxiliary facility for aircraft take-off and landing, usually deployed at both ends of the runway, the long-distance navigation station is generally seven or eight kilometers away from the runway, and the short-range navigation station is usually two or three kilometers.

Li Zhan's contact with the tower when they landed often said "seven kilometers is good" and "eight kilometers is good", which means to tell the tower pilot that he has confirmed his position, and his position is near the long-range navigation station - the plane flew over the long-range navigation station, proving that there was no yaw. The navigation station near the airport is also an important part of the blind landing assist system, which is a support facility to assist the pilot in landing without visual distance.

The reason why Li Zhan's blind landing on the highway was extremely difficult was precisely because there was no auxiliary equipment on the ground that could assist him in confirming the position and altitude of the fighter, and the flight parameters generated when he landed were important reference data for subsequent pilots.

In addition to the navigation station near the airport, there is also a navigation station deployed on the ground where the route passes, which is an important support facility to ensure that the flight follows the correct course. For example, not long ago, Li Zhan and Chen Fei returned from the Forgotten Reef, and the Seventh Navigation Station that they passed before entering the Pearl River Delta region is this kind of facility, and if Li Zhan does not receive data from the Seventh Navigation Station, it means that he has deviated.

In addition, there is another type of navigation station that is very important, that is, the navigation station deployed in the border area to provide navigation information for domestic and international flights, and is also the handover point for domestic and foreign flight management.

At this time, Li Zhan and the Hongla navigation station that they were about to fly over was such a navigation station.

It should be pointed out that the military and local navigation stations are two independent systems, also known as military navigation stations and civilian navigation stations, the former belongs to the units within the establishment of the air force, and the latter belongs to the civil aviation system.

The Hongla navigation station is not a Hongla navigation station, because this point is larger than the general navigation station, the scale is much larger and the level is much higher, it is the scale of the station, almost all international flights to and from West Asia, Europe, and Africa have to fly over this navigation station, and the station provides the last navigation in the territory, and it is also a point to hand over the management rights to the overseas airspace information region.

The navigation stations near the airport are all deployed underground, to put it bluntly, they are underground buildings, and the roof is slightly exposed to the ground, which is to avoid collisions with aircraft. However, navigation stations such as the Hongla Navigation Station are generally built at high places, which helps to increase the detection range and range of the radar.

Hongla Navigation Station is the highest altitude navigation station in the territory and the highest altitude navigation station in the world.

This is the reason why the formation is ordered to climb to 7,000 meters, which is the route of civil aviation flights, which is generally not occupied by troops, and below 7,000 meters, it is usually not approved for use by inbound aircraft.

The radio data sent by the two points of the Hongla navigation station was received by Li Zhan, and his fighter plane was the intersection point of the "lines" sent by the two points, and then he could know his specific position very clearly and accurately, and also know the specific position of the formation, as well as the positional relationship between him and the Hongla navigation station.

The standards of third-generation aircraft include external perception capabilities, such as relying on airborne equipment to be able to confirm their own position, which is very critical in combat.

Since the 60s, our officers and men have built this navigation station at an altitude of 4,100 meters, and it has carried out many major support tasks, and it is a heroic station. At the Spring Festival Gala every year, the host of the Spring Festival Gala on behalf of the people of the whole country greets the commanders and fighters of the troops who are sticking to the border.

At this time, it was not Li Zhan's turn to contact the Hongla Navigation Station, but Tang Guozheng on the Y-8 was greeting the comrades of the Hongla Navigation Station on behalf of all the military exchange delegations.

After bidding farewell to the Hongla navigation station for only a few minutes, the formation entered the territory of the Basij, over a barren mountainous area, where it was even possible to overlook the buildings of the Hongla port.

The formation of the military exchange group officially began their five-day exchange trip.

PS: It's still the same old saying, don't substitute reality. Red Lala is Red La, and if you have to look at it as Red Jerab, you will be wrong.
