Fighter pilots, especially inexperienced pilots, often experience problems such as discomfort, black vision and illusions due to altitude, air pressure, overload and phenomena natural when flying at high altitude. their handling can lead to disasters and must be taken seriously.
Altitude affects temperature. The temperature decreases as the flight altitude increases. For every 1,000 meters, the temperature decreases by approximately 6.5. When the altitude reaches 10,000 meters, the temperature can reach tens of degrees. below zero. Some This is why the mountains are covered in snow all year round. But there is air conditioning in the fighter plane. The reason why pilots wear leather flight suits in winter is because it is cold on the ground and when they first get on the plane, if you encounter any circumstancesspecial needs, you will parachute. get too cold if you don't wear too much.
The influence of atmospheric pressure. Air pressure also decreases with increasing flight altitude, plus air pressure decreases with altitude. This occurs in the aircraft's temperature regulation and augmentation system. When a malfunction occurs, human organs can expand and "explode", endangering the pilot's life and the safety of the flight. When pilots fly at high altitudes, oxygen levels decrease and pilots are sometimes prone. to a lack of oxygen at high altitude, difficult to detect, leading to accidents.
Aerial wonders As the flight altitude increases, especially when it reaches more than 15,000 meters, the color of the sky is no longer the "blue sky" we see but the "sky blue”, but it is very deep. , silent, the plane flies very welln, without any disturbances or bumps, new riders may be a little scared. The earth begins to “arc” and when you fly west in the evening, you can see the fiery red sun still hanging on the edge of the earth. Effect of overload: When the aircraft is pulled up with a large load, the blood in the human body will flow in the opposite direction of flight, causing temporary ischemia of the human head. At that time, the human's eyes will be dark. and nothing can be seen, but the human body will. Thoughts are still very clear, this state is called “black vision” in flight. When the plane is used to change the state of the plane with a large load push rod, the pilot's head is filled with blood, his eyes are full of red, and he can't see anything clearly. This situation is called “red vision.” flight. In order to overcome these two situations in flight, pilots must strengthen their training.nt physics and wear anti-gravity flight suits when they fly.
The main factors that cause the illusion of flight
Flying at night The visible distance of flight at night is much greater than that of the day if the visible distance of flight during the day East. 10 kilometers, it may be invisible at night. When it reaches about 20 kilometers, it is easy for the pilot to think that the distance is long. When flying at night, in addition to instrument flying to maintain the status of the aircraft, it is also necessary to look at the lights on the ground. When flying in relatively remote areas, because there are fewer lights on the ground, it is easy to confuse the stars in the sky with lights on the ground, causing "sky and earth reversal" , creating an illusion. There are few reference objects during a flight at sea. Maintaining the route and the pilot's judgment must rely on the instruments of the avion. It's endless and it seems long. It is difficult to survive if the plane has problems. and pilots are prone to fatigue. Moreover, the color of the sea is blue in the air, and the sky is also blue. The clouds and islands on the sea can easily confuse the sky and the ocean, creating an illusion.
Flying in the clouds When flying in the clouds, people's mood will be different depending on the nature of the clouds. If you fly in stratus or light cumulus clouds, you will feel more relaxed and even relaxed. unromantic. When flying in Cumulus Congestus or Cumulonimbus clouds, the aircraft is very turbulent. The pilot feels that the plane's condition in the clouds often has a significant error with the instrument. The pilot feels like he is flying forward, but he may be flying upward. down or to the side. At that point, if the pilot fails to make a correct decisionect calmly, an accident may occur. When flying into the clouds at night, pilots can see the electrical sparks produced by friction between the clouds and the aircraft, as well as the aircraft's navigation lights producing a huge light display in the clouds. clouds.
Very low-flying planes fly at very low altitudes on land. There are reference objects for flying, and you can feel the speed of the plane. When the pilot looks closer, he sees a "white light", and when he looks far away, he sees mountains and mountains. . For birds and treetops, the situation is more complicated. When flying at very low altitude over the sea, the water in front of the plane appears to be much higher than the plane. It's like a blue wall blocking the front, and white waves occasionally rise into the sky. nervous, under great pressure and easily tired.
Fly after thesnow. After the snow falls, the ground is covered with snow. The first thing the pilot feels is that he is dazzling. The sunlight in the sky and the reflective light from the ground converge. the pilot’s sunglasses, creating a “glow”; The pilot made a significant error in assessing the flight altitude. He estimated that the plane was very low to the ground, but in fact it appeared to be flying at an ultra-low altitude. as if she was about to hit the ground. Third, the appearance of the earth was completely different. The rivers and lakes were no longer blue, and the heights of the mountain peaks were different. on the south side of the mountain had melted, but the snow on the north side of the mountain had not melted. At that time, when the pilot looked south, he saw a black spot, and to the north, a large area. white spot. Many factors affect flight. To overcome the impact of problemsabove on the flight and prevent the occurrence of flight accidents, we often need to strengthen aviation studies, repeatedly study the topography of the airspace, understand the characteristics of the natural landscape, and strengthen targeted adaptive training, such as ground flight illusion simulation experience and aerial simulation experience, flight illusion simulator training, instrument spatial orientation ability training, psychological training, etc. , continually enriches experience and the ability to deal with particular situations.
