Chapter 078 Climbing, the speed pushes me to the back of the chair
Before taking off, Li Zhan ate. It was early three in the afternoon. After peeing, he didn't feel hungry, but he still bit into a piece of chocolate given by the aircraft maintenance staff.
At 3:15 in the afternoon, Li Zhan drove the J-8fr numbered 101 from Longcheng Airport directly into the dark and dark sky in the west. He was no longer greedy for the sound of the approaching girl, and stepped across the approach platform.
, contact Nanzhi directly.
He flies a fighter jet, so there is no need to follow the procedures of civil aviation. Moreover, in terms of airspace priority and route priority, civil aviation is on the sidelines, so it is troublesome.
At this time, there are still many civil aircraft flying over Yunnan and Guizhou provinces, and several routes have to pass through rainfall clouds and southward cold air. The civil aviation control department has been paying close attention to the meteorological conditions of the airspace they fly over, and
The air traffic control department of the army has also been providing assistance and helping to clear the relevant airspace so that civilian aircraft can use the shortest route to stay away from complex weather airspace.
Judging from the flight path map, all the planes were flying outward, and only the number "jh101" representing Li Zhan was dragging a long dotted line towards the center of the huge cloud.
Flying under complex weather conditions has always been a high threshold. Pilots with this ability are generally experienced pilots who have flown for two thousand hours, and it is not uncommon to have three or four thousand hours of flight time. How to evaluate complex weather conditions
How difficult is it to fly? In a nutshell, it is one of the criteria for measuring an ace pilot.
Li Zhan is very unfamiliar with many practical subjects, and has even never been exposed to some subjects at all. However, his flying skills, including day and night flying in complex weather conditions, flying across day and night, and handling of emergencies, make him almost the best in the Second Division.
Among those people.
Otherwise, he would not be qualified to sit in the cockpit of the J-8fr, and he would also be given a number like 101.
Despite this, after entering the southward cold air mass from an altitude of 3,000 meters, Li Zhan also clearly felt the power of complex weather. Affected by the Siberian cold air cloud, heavy rains have fallen in the western part of Guangxi Province, stretching for hundreds of kilometers.
Within the scope, because the southwest region is constantly being supplemented by vigorous water vapor rising, it has formed continuous heavy rainfall. The measured precipitation in the upper reaches exceeds 100 milliliters and continues to rise. It is only a matter of time before a heavy rainstorm occurs.
Therefore, there is no suspense. Li Zhan first encountered the problem of sharp decline in visibility. After diving into the rainfall area, everything he looked around was clouds and fog.
Li Zhan turned on the search radar and reported to Nanzhi at the same time, "Nanzhi, this is Yaodongyao. My visibility is not good. Please lower the altitude."
He is not very worried about crashing into mountains or mid-air collisions. The J-8FR is modified based on the F type. The nose of the aircraft has the same fire control radar as the early J-10, and its performance is even more advanced than that used by the early Su-27.
Don't underestimate the F-type just because you are an old man. If it weren't for the flaw in the aerodynamic layout, it is estimated that it can continue to be modified and used for decades like the H-6.
The commander of the South Point paused for a moment and said, "Yao Dong Yao, you go up to Eight Thousands first and try to see if you can fly on cumulonimbus clouds. Here we need aerial photos of cumulonimbus clouds."
"Understood, I'm climbing now, up to 8,000." Li Zhan didn't hesitate at all. He put on the oxygen mask first, then pushed the accelerator lever. When the speed came up, he decisively pulled the lever to climb.
The excellent acceleration performance of the J-8fr, which was born out of Ba Ye, came into play. With an average climb rate of more than 270 meters per second, it took less than half a minute to reach an altitude of 8,000 meters.
However, after reaching eight thousand meters, all Li Zhan could see was still clouds, the airflow was very strong, and the fighter plane was severely turbulent. He continued to climb while reporting to Nan Zhi, "Nan Zhi, I am Yaodong Yao, eight thousand
If it’s not enough, please continue to climb higher.”
"Agreed, there are no aircraft in your airspace, be ready to report." After confirming that the airspace was clear, the commander of the South Point decisively agreed to Li Zhan's request.
Li Zhan continues to climb.
I sang "Thirty Thousand Feet" silently in my heart: climbing, the speed pushed me to the back of the chair...
Since he started flying, he has never tried to climb from an altitude of 2,000 to 3,000 meters to an altitude of 10,000 meters. In fact, for fighter jets, the opportunities to fly at an altitude of 10,000 meters are becoming less and less. Unless it is in a vast area
Flying over the ocean.
As the local economy continues to develop, more and more routes and airspace are handed over to local civil aviation, making a great contribution to economic development. As these increases and decreases occur, the air force's training airspace must continue to be compressed, and even in order to free up
Not only have many airports been transferred to local areas, some important airports have also been relocated.
Just like the trap Chen Fei almost fell into, the local government only focused on economic development and neglected homeland air defense security, insisting on building high-rise buildings where the take-off route passes. This matter has not been resolved until now. As Li Zhan said, once completed
, the fighter planes at the West County Station have to climb or turn at a large angle as soon as they leave the runway. Ironically, this forces the pilots to improve their skills...
When the front suddenly became clear and the bright sun was at eleven o'clock, Li Zhan breathed a sigh of relief and glanced at the altimeter. The altitude was 13,000 meters. It was obvious that the power of the fighter plane had declined greatly.
serious.
This altitude is very safe and no commercial aircraft will fly at this altitude.
He resumed level flight and maintained heading 270.
"Nan Zhi, I am Yaodong Yao, altitude is 13,000, heading is 270, cruising speed, the clouds are below me, please identify it with radar, if there is no problem I will start taking pictures." Li Zhan called Nan Zhi, because
Wearing an oxygen mask, my speech sounded a little loud, but it was still very clear.
The commander of the South Point quickly replied, "Yao Dong Yao, you are in a good position. You can start aerial photography. Maintain the heading speed for five minutes, and then perform a circling flight. To be continued later."
"Understood, hold for five minutes and circle in a circle." Li Zhan turned on the high-speed camera and began to take pictures of the huge clouds below.
There are cumulonimbus clouds and unformed cumulonimbus clouds in those clouds, as well as thunderstorms, and rising air currents carrying abundant water vapor. It can be said that there are all kinds of monsters and monsters gathered together. If he hadn't climbed decisively on the periphery, I'm afraid this would
It is just a lone boat floating in the strong wind and waves.
When he started circling, Li Zhan carefully observed the huge clouds, and the more he looked, the more frightened he became. Of course he was familiar with the weather. A pilot who is not familiar with the weather is like driving a car who is not familiar with the traffic rules. What kind of weather can't fly?
You must be aware of what kind of weather you can barely fly in, and where the weather will change, and be forward-looking.
What's more, during the grounding period, he not only followed the maintenance work, but also often went to the weather station to learn more about meteorology.
Don't think that the leader is a fool. There is a good reason why he sent you here. For example, not only are you highly skilled in flying, but your ability to interpret the weather is also outstanding.
Li Zhan couldn't wait for the technicians to interpret it after landing, and reported his opinion to Nan Zhi without any hesitation, "Yao Dong Yao called Nan Zhi, this huge cloud layer below me is not simple, combined with the thickness passed through during the climb
, once this cloud layer transforms into a cumulonimbus cloud, it will bring long-term heavy rainfall."
The commander of the Southern Point obviously knew the details of Li Zhan, and he judged him very seriously. He immediately said, "Yao Dong Yao, keep observing, the radar is confirming your position."
"To the south, I should be at the junction of Yunnan and Guizhou provinces. The Hengduan Mountains are not far away from the heading 270." Li Zhan said.
The commander of the South Point smiled subconsciously and said, "Yao Dong Yao, how do you know? Is it calculated through the bearing data?"
"No, I know the feeling of flying, how far it has flown and where it is," Li Zhan said.
He is a person who experienced a power outage in the cockpit during a night flight, a landing gear failure and a successful emergency landing. The feeling of flying can be said to have reached a new level. One of the reasons why flying is a high-risk profession is that there are almost no aircraft in the sky.
It’s a reference. You can’t fly in a variety of environments by simply relying on landmarks, let alone fight. If a person drives on land and there are no marking lines on both sides, the chance of running off the road will increase significantly, and there is no line in the sky.
What to do? In addition to technical instruments such as compasses, we can only rely on the pilot's feeling and ability to perceive body balance. This is the reason why pilots need to conduct anti-syncope training.
For another example, low-altitude sea-skimming flight has always been regarded as a high-risk combat subject by Hainan Airlines, because once the pilot has an illusion for even 0.5 seconds, the fighter plane will plunge into the sea.
After the radar identified and confirmed Li Zhan's location, the personnel on duty at the South Point were all sincerely impressed. Several of them gave a thumbs up. It didn't matter whether Li Zhan could see the location of the No. 101 J-8fr fighter confirmed by the radar and Li Zhan's.
The judgment is basically consistent.
"Yao Dong Yao, your judgment has been reported to the local government. Now you need to keep circling and continue to monitor this cloud." The commander of the South Point issued new instructions to Li Zhan.
Li Zhan did not stop observing the clouds below. He thought for a moment and asked for instructions again, "South Point, the area where Yun Gui meets Yun Gui is the place with the largest altitude difference. If there is super heavy rainfall, the water level upstream will definitely surge.
I requested to conduct detection under the clouds and conduct aerial photography of the relevant areas. If I don’t take photos now, I am worried that there will be no conditions for flying if there is heavy rainfall. In addition, I also need to collect relevant data about the clouds.”
The risk of doing this is very high, but compared to doing it after super heavy rainfall, the risk is relatively small. On the other hand, the ground weather radar observed that the cloud height was still 2,000 meters, and Li Zhan descended to 2,000 meters.
If you take aerial photography at less than 1,000 meters, there will be no problem.
However, to descend to an altitude of 1,000, Li Zhan had to swoop through a super-large cumulonimbus cloud layer several kilometers thick.
However, that's not the hardest part!
Don’t forget, the two thousand meters in the clouds is an altitude, not a relative height. The area where Yunnan and Guizhou meet belongs to the edge of the Yunnan-Guizhou Plateau, with an altitude of more than one thousand meters!
This means that Li Zhan will face the situation of flying among the mountains as soon as he emerges from the clouds.
