The rain-washed sky was exceptionally clear, and six vintage planes formed a dense formation to perform difficult aerobatics back and forth at low altitudes, adding color to the quiet sky again. Those old planes also have a lot of beautiful patterns and glowing light strips on them, which looks even more dazzling and colorful.

Don't think that the old birds will be rusty if they don't have contact with the sixth year of beginner's education for a long time, in fact, it's like how well you learn in college, you will forget what you learned in high school or even junior high school, but it is basically difficult for you to forget the arithmetic you learned in elementary school.

It's like writing, if you dare to take out what you write and show it to others, you at least know the six elements of composition, and the basic skills are definitely there.

Whether it is Captain Gao, a pilot who has been transferred to civilian service, or an active ace like Li Zhan and Chen Fei, they will never forget the most basic control method of the beginner's sixth class, and the aerobatic maneuvers they want to use are the basic flight maneuvers that every pilot with combat effectiveness must learn.

Just like blind manoeuvres, any pilot must have the ability to fly under unrelated conditions.

Therefore, after flying twice, the cooperation of the temporary six-plane flight demonstration team became more and more tacit and mature, and the overall aerobatic action was completed better and better, and everyone quickly had a feeling of being handy.

The Chujiao-6 can continue to fly for three and a half hours at an altitude of 1,000 meters and at a speed of 180 kilometers per hour, and the ability of this aircraft to stay in the air is not weak. Sharpening knives and cutting wood, Li Zhan and the others all took off with full fuel, so they simply asked the district management center to extend the joint training time to two hours, and there was plenty of room to return anyway.

Using these two hours, Li Zhan and others fine-tuned the content of the performance while practicing together, in order to achieve the best effect possible. The theme of the Flying Spring Festival Gala is the air show, and they are responsible for the main event, so it is best to be perfect.

When Li Zhan was reliving his old dream in the first six years, in a separate room in the maintenance hangar, the work of Zhang Chongming's technical analysis team had reached a critical stage. They are responsible for analyzing the data obtained from the J-16 actual combat test flight, and reporting the analysis results to the air division, so as to provide a technical basis for the air division to make decisions on the J-16 aircraft.

The task is very important, so even if they knew that they were going to participate in the Spring Festival Gala in the evening, the comrades of the technical analysis team were not swaying, and they were still concentrating on the analysis of the relevant data of the actual test flight. The responsible department of the air division is manned 24 hours a day to receive their analysis results at any time, and the No. 1616 J-16 encountered many accidents this time, and the crew carried out many unplanned flight test actions, and the air division has attracted attention, so the mood of waiting for their analysis results should be more urgent.

Gan Tingting is in charge of this part is relatively important, because she is docking with the front cabin pilot Li Zhan, how important Li Zhan's right to speak in the actual combat test flight is, how important the work she is responsible for, and there can be no mistakes at all.

In short, the results of the actual combat test flight are not only related to the verification and mining of the performance of the fighter, but also related to the tactical use of the fighter, the latter being the most important.

Li Zhan found that there were some misunderstandings in the use of the Su-30MKK by the troops, and he also put forward his views to his superiors, but empty words are obviously not good, and they must be supported by practice.

So from this point of view, Gan Tingting's analysis is also very important to Li Zhan.

Conducting a test flight is by no means just a matter of driving the plane well, just as the test pilot unit often says: an excellent test pilot is also an excellent technical engineer. There are many examples of test pilots in turning over the guidance of manufacturers to improve their aircraft, and there have even been examples of maintenance support manuals sorted out by veteran mechanic non-commissioned officers replacing manufacturers' manuals.

The person who uses it has the most say in what kind of weapon it is, especially when it is against the opponent's similar weapons. For example, when it is in a confrontation with the F-16 and Mirage-2000, which are mature third-generation aircraft of the world's main force, what is the strength of this fighter.

Superiors need to quantify data when making some considerations and decisions.

This is the significance of the actual combat flight test and the task of the flight test technical analysis group.

Therefore, when Gan Tingting finished the last step of the calculation, she saw that the conclusion reached was very different from the manufacturer's prediction, she subconsciously stood up and raised her hand to report: "Director! ”

Zhang Chongming was stunned for a moment, walked over quickly, didn't ask anything, took the data directly, and suddenly his face changed slightly, and asked in a deep voice, "How many calculations have you made?" ”

"Thirteen times, I calculated five times by hand, and the rest was done by the center's supercomputing, and the results were consistent." Gan Tingting replied in a low voice.

Nodding slightly, Zhang Chongming motioned to Gan Tingting to continue working, and then walked to the room with the conclusion report, picked up the special line and went directly to the relevant departments of the air division to report.

"Yes, chief, it has been calculated repeatedly, the data has been checked repeatedly, and yes, based on the data currently available, this is the final result. Yes, understood. ”

After Zhang Chongming reported in a deep voice, he turned around and said to Gan Tingting, "Xiao Gan will come over and ask Team Leader Li to come over!" ”

"Director, he seems to have flown and practiced together for the evening party." Gan Tingting hurriedly stood up and reported.

Zhang Chongming waved his hand and said, "Let him come back quickly and inform Chief of Staff Tang." ”

"Yes!" Gan Tingting, the only one who had temporarily completed the stage task, acted as a herald and hurriedly went.

In the sky above the southern suburbs, Li Zhan was preparing to conduct the last hour of joint training with everyone, and the district management center called him: "Big Bird No. 1, there is an emergency, please return immediately, and the rest of the planes will continue to practice together, and it will be over." ”

Li Zhan was surprised and said, "Big Bird No. 1 received it, return immediately, over!" ”

There were a lot of doubts in my mind, but first I had to carry out the instructions. Without the slightest hesitation, he immediately broke away from the formation and returned home.

He thought he would circle a little and wait for the approach desk to arrange a gap for him to land, but he received the order to land immediately, and he clearly saw that there were at least five passenger planes hovering over the airport. This is not the case unless it is very urgent, as it would mean that more than a dozen normal flights would be affected.

Anyone who has ever hiked knows that the person at the front of the line suddenly walks a few steps faster, and the person at the back of the line basically has to run to keep up, and the longer the line, the more obvious this lag becomes. A five-minute delay in the scheduled flight time now is highly likely to result in a one- or two-hour delay in the evening.

Li Zhan couldn't think of what the emergency was that required him to return to the ground immediately.

Is there an emergency live-fire mission?

The 1616 J-16 can't do this job, the planes are all broken.

Landing neatly, there was already a guide car waiting, quickly guiding him directly back to the maintenance hangar, crossing several taxiways on the way, and more than a dozen flights on the ground all stopped to give way.

Li Zhan parked the plane and jumped down on the wings, Gan Tingting was already waiting, and after a few words, he took Li Zhan to the analysis room in the maintenance hangar.
