People always have nostalgia complex. If you drive more planes, you will miss the earliest model you drove. Li Zhan is almost like this now. When he came to the transition, he had some experiences. Now there are different things in the dark cabin flying.
Feel.
Most night flights have starlight as reference objects. Pilots are sure of "up and down", while dark cabin flights can't see anything at all. However, during night flights, pilots may confuse starlight with the lights on the ground, and the consequences are
It is catastrophic. If the cover is not tight during the dark cabin, the pilot will easily regard the translucent side as the sky due to the inertia of thinking, which will also have fatal consequences.
As a means of instrument training, dark cabin flight requires pilots to focus all their attention on instrument information and ground instructions, rather than trying to find gaps and look outward. Follow ground instructions and rely entirely on instruments to fly. This is the pilot.
Basic skills to possess.
Regarding the landing, Li Zhan has made many improvements and changes, including simulating the maritime environment and arranged three sudden commands that require short flight time and two low-altitude passes.
What Li Zhan needs to do is to simulate the ship hook blocking cable for two hours without interruption under the conditions of flight of the dark cabin, which is an average of ten minutes each. He needs to do ten times, and finally discuss and analyze according to the final results.
To find training standards.
What standards should the pilot meet in the subject of dark cabin flight simulation landing before he can enter the next stage of training? Everyone doesn't know now, so Li Zhanfei needs to come out.
With him here, the leader will not consider others, and others will not compete for them, anyway, they can't grab them.
Of course, Li Zhan was extremely happy. Last year's flight hours decreased significantly month-on-month. Since the beginning of spring this year, he has been fishing for three days and drying the net for two days. If he doesn't work hard, he will have to go home to inherit tens of millions of property.
Flying hours are the most intuitive and obvious manifestation of pilot qualifications.
Old Chen issued instructions to Li Zhan step by step. Li Zhan strictly operated the aircraft according to the instructions. The ground radar system continued to measure the real-time position of the No. 037 J-7eggh. Once a deviation was found, the pilot would be notified immediately and organized dark cabin flight training with ordinary troops.
It's no different.
The difference is that Li Zhan drove the plane very fast, and the WS-XX turbofan aircraft engine with a sharp whistle steadily provided power to push the fighter with an eight-ton weight at this moment about three diagonally above the west side of the tower.
Flying over at a height of 100 meters at a high speed, which made the tower commanders who were used to the stable style in training feel a little excited.
Li Zhan's movements in the sky are very bold. When adjusting his posture according to ground instructions, he usually chooses very vigorous but most efficient maneuvers to complete. For example, if he lowers the height, he will just turn 360 degrees and be quick and neat.
The fighter reaches the specified height instead of using the angle changes of the horizontal tail to slowly lower the height.
As for fighter jets, they must have the style of fighter jets, otherwise what is the difference between them and transport aircraft?
During the second round, Li Zhan put down the landing gear. After the signalman not far from the commander confirmed that the front and rear landing gears fell normally through manual observation, he immediately reported to Lao Chen.
Then came the "landing ship to return to flight".
After two rounds, the landing must be completed within ten minutes, and there is plenty of time. Li Zhan accelerated his flight speed again. At this rhythm, he could "lander" at least fifteen times in two hours. Old Chen head
Satisfied with Li Zhan's initiative.
The 037 J-7eggh joins the standard downward line for the third time. The standard downward line given by the landing radar is presented to the radar crew through the display screen. It was a radar oscilloscope tube a few years ago, and there are still a small number of troops in use.
Adjustment instructions are issued to the pilots according to the specific situation of the aircraft, and the pilots passively execute the entire process. This passive guided landing method is the technology of the old Russians. Our army has used it for many years, but the troops have gradually adopted the civil aviation landing guidance technology.
, proactive, technology from the Ugly Country, has been used in civil aviation.
"Dong Sanguai, you are getting grounded quickly, pay attention to the speed." Old Chen saw that the entry speed of the No. 037 J-7eggh exceeded 30 kilometers, reminding Li Zhan.
The grounding speed of the No. 037 J-7eggh is thirty kilometers faster than the regulations, which is not a good sign.
Li Zhan quickly adjusted, looked at the speed of the meter, frowned slightly, and replied, "Tower, there should be something wrong with my airspeed meter, the reading is normal."
Old Chen felt a stern and said quickly, "Listen to my guidance and stay in shape."
The airspeed meter shows the specified landing speed, but the actual landing speed of the fighter jet is thirty kilometers faster.
It was not a big problem. The fighter's posture was maintained very well. Li Zhan slowly closed the accelerator based on his experience. After knowing it, he asked the tower, "Tower, how fast is the tower now?"
"You have to slow down another five kilometers, don't be anxious." Old Chen's tone was very stable.
The No. 037 J-7eggh, five kilometers away from the runway, still has altitude and distance, so there is no need to worry at all. There is only an error in an instrument, and when a problem is discovered, there are many solutions. At this time, the pilot's experience is reflected.
"Okay, keep steady, maintain the pitch angle and maintain the decline rate." Old Chen nodded very satisfied and ordered Li Zhan.
Li Zhan is too familiar with the J-7, especially the No. 037 J-7eggh. In just two seconds, he relied on his experience to stabilize the airspeed of the fighter at the specified speed, with no more or less very accurate. In order not to change the fighter
He only adjusted the pitch angle through the accelerator, which further highlighted that he was extremely skilled in operating the accelerator rod.
Entering three kilometers, the No. 037 J-7eggh, which had already put down the landing gear, gradually changed from the original posture that looked slightly lowered, but the fighter still maintained its original descent rate and steadily headed towards the blocking cable on the runway.
The area falls.
The next key link is that the pilot will perform a series of controls after the rear landing gear touches the ground, including the throttle, flaps, brakes, rudders, and until the fighter glides to a speed below twenty kilometers per hour.
Obviously, there is a problem with the airspeed meter and the training can no longer be continued.
Old Chen told Li Zhan: "Land normally, stop flights, and repair the plane."
"Dong Sanguai understands it and lands normally."
Li Zhan felt a little regretful. The two flight hours that he had finally waited for were over in less than ten minutes. He wanted to contribute his strength to the construction of a strong People's Navy aviation force.
The heart was traumatized.
The No. 037 J-7eggh had put down his tail hook according to the training requirements. When the fighter fell steadily, the tail hook hooked on the second infrared ray, and the intermittent signal immediately appeared on the monitor on the tower.
At the same time, instantaneous photos taken by high-speed cameras also appeared. The posture of the fighter jet is very standard, and the position of the rear landing gear touching the ground is perfect. The staff officer in charge of the post raised his hand and reported loudly: "Report! Dongsanguai standard landing!"
Old Chen nodded slowly with satisfaction and said, "This kid is capable."
Although he encountered an emergency situation of the airspeed meter failure, Li Zhan still completed the landing operation perfectly.
The No. 037 J-7eggh canceled the speed reduction parachute, so he kept gliding for more than 700 meters before slowly leaving the runway, and drove directly into the maintenance hangar and the crew immediately carried out maintenance.
The speedometer of an aircraft is very complex, showing four speeds: airspeed, meter speed, ground speed and Mach number. Airspeed refers to the speed of the aircraft relative to air, which is composed of airspeed tubes (the pipe with the pointed tip of the aircraft nose.
) The ground speed is easily understood by measuring and the speed of the aircraft relative to the ground.
The commonly used meter speed for pilots is actually an uncorrected airspeed, and the error usually does not have a large error. The airspeed mentioned in the land-to-air dialogue between Li Zhan and Lao Chentou refers to the revised meter speed, rather than
The meter speed that is often used is also called vacuum speed or true speed.
This is because the weather conditions in the area where the fertile soil flying training base are complex, half of the mountain and half of the sea. When the fighter takes off, it is flying at sea for half of the time. Atmospheric pressure, air density, temperature and other factors are relatively affected. Therefore,
Pilots are required to use airspeed meters, that is, airspeed.
In fact, if the meter speed does not fail, it will not have a great impact on the normal flight of the aircraft. Just now, Li Zhan quickly calculated the error between the airspeed and the meter speed and then used the meter speed as the basis to measure the airspeed of the fighter.
Adjusting to the required value. If any speed information is completely impossible, it will be difficult for him to achieve such accuracy in such a short time. Even so, he can correct the airspeed of the plane within two seconds, which is a good reflection.
He has solid basic skills in manipulating.
Zhang Xueyang, Cao Fufei, and Tang Leilei who were waiting in the flight briefing room rushed to the news and arrived at the maintenance hangar. Zhang Xueyang smiled and said, "Old Li, your bad luck is really evil. You will be out in less than ten minutes in the morning.
question."
"I'm still wondering. The plane has been repeatedly tested and flew on Chengfei, and it has been carefully treated before it has been transferred. The instrument should not be so fragile." Li Zhan was of course very puzzled.
The cockpit of the No. 037 J-7eggh has long been no longer the same dilapidated appearance. The cabin display layout of the one-level and three-speed shift is exactly the same as that of the JF-11, which is much more advanced than many early third-generation aircraft, and even those aircraft are not yet complete.
The fixed J-15 still uses a mixed style of instrument and display.
Despite this, people are still used to using "domain" and "domain" to express the cockpit display interface.
Therefore, there is an error in a single flight data, which is likely to be a problem with the airspeed tube. After discovering the problem, Li Zhan calculated that the display error between the meter speed and the airspeed is not an uncorrected error, so the conversion should be excluded.
Module failure.
"Don't worry, it shouldn't be a big problem." Zhang Xueyang comforted.
The deficit is actually a small blow to the quadron of the dark cabin, which is full of confidence, when Cao Fufei took a deep breath of the fishy wind that was floating from the sea, and said casually, "Can it be?
The salt problem is that the salt content of the air here is much higher than that inland."
Li Zhan subconsciously raised his eyes unjustly, and his eyes passed through the first training area and then saw Haitian and Yise.
Yes, it may be a matter of salt!
"Captain Peng! Is it because of excessive salt content that fails the airspeed tube?" Li Zhan turned his head and rushed to Peng Chubin, the first team leader of the maneuver brigade who was leading people to repair the situation.
Captain Peng Chubin was stunned and then slapped his high fives, "It's very likely! Give me ten minutes!"
He is also a straightforward person.
Cao Fufei was a little stunned at this moment, "I won't be right?"
Li Zhan had already run over to follow the maintenance service. Tang Leilei blinked and said, "Senior Brother Cao, you may be more lucky than the No. 1 brother."
Navy pilots all know the importance of anti-corrosion. Fighters have been flying in the sea and air for many years, and all the seaport stations are on the coast, all of which are high-temperature and high-salt environments. The anti-corrosion performance of carrier-based aircraft must be targeted, and even in the past ten or twenty. In 2019, my country's material technology was not as strong as it is now, and the anti-corrosion of carrier-based aircraft was a major problem for scientific researchers.
When Cheng Fei made ship improvements to the No. 037 J-7eggh, did he not consider that the fighter must have strong anti-corrosion properties to work in special environments such as high temperature and high salt?
Obviously, they have taken into account the relevant treatments. For example, all exposed components are made of materials with good corrosion resistance. The electronic components of the avionics system inside are also made of materials with good corrosion resistance.
The carrier-based aircraft was tested in accordance with the information of the troops' weapons and equipment standard instructions, and was re-delivered to the troops after confirming that the standards were met.
Therefore, the possibility of airspeed tube failure due to salt problems is not very high.
Cao Fufei looked at Li Zhan and simply took off his white labor protection gloves and put the flight helmet aside. He conducted a test of the airspeed tube with Peng Chubin. He couldn't help but ask strangely, "Has Old Li always been like this?"
Pilots and crews are not new to the aircraft. In fact, many pilots often do this to increase their understanding of fighter jets. However, it is rare to see such urgent styles as Li Zhan, and even more so, he is the case.
There is no need to waste time on exploring the construction of war institutions.
Zhang Xueyang and Tang Leilei looked at each other, and the former said, "Old Li is just anxious. This is a good start and it turns out that the door is dark. The training standard has just started to explore and the plane malfunctions. I am also anxious."
"Yes, everyone is anxious." Cao Fufei believed it and said, "Old Zhang, should you ask Mr. Chen for instructions, let's use J-11 a to fly."
Zhang Xueyang shook his head, "No, Lao Li said that he could not get on the J-11 a before the hidden cabin of Dongsanguai J-7 landing."
To figure it out means to initially find out the basic training standards, otherwise you will not know how far you have practiced. The No. 037 J-7eggh has a tail hook, and the landing gear and other things have been improved according to the standards of carrier-based aircraft.
So relatively speaking, using this plane flight standard is relatively objective.
After all, the J-11a is a land-based fighter.
Tang Leilei was a little embarrassed and forced himself to not tell the truth.
Suddenly, Li Zhan over there gasped, "It's all rusted!"
