What factors are related to the flight altitude of the fighter?

I think it should be the engine, because the engine is oxygen hungry, and the amount of oxygen consumed depends on the design of the engine, and the oxygen becomes thinner and thinner as the altitude increases, so in general it is related to the engine. Of course, there is also something to do with the aerodynamic shape of the aircraft.

One is the thrust of the engine, the other is the pressure resistance of the aircraft, and of course, the stability of the maneuvering at high altitude is also very important.

It depends on many factors, including aircraft weight, aerodynamic shape, airfoil, angle of attack during flight, air density at that altitude, flight speed, and engine thrust.

In general, commercial airliners fly at altitudes between 6,000 and 12,600 meters. Because as the altitude increases, the air will become very thin, and the oxygen will be very low, which cannot allow human beings to breathe normally, so civil airliners cannot fly too high.

I also made some inquiries on the Internet and found that under normal circumstances, civil airliners generally fly between 6 kilometers and 12,600 meters. This altitude is also relatively high, can not continue to rise, if continue to rise, the cabin of oxygen may become less and less, it is possible for passengers to need oxygen, which is very bad. Because as the altitude increases, the air will become thinner and thinner, and the oxygen will gradually decrease, and it will not be able to allow humans to breathe normally.

And the air pressure in the air is relatively low, if we stay in the low pressure for too long, it may make the human body have a negative pressure effect, make us dizzy, and may also make the blood circulation poor. Therefore, the flight altitude of civil airliners cannot be too high, and must be kept between these two values, so that passengers can be more comfortable and will not have problems with passengers.

If you've been living at a lower altitude and suddenly go to a higher altitude, there's a chance of a lack of oxygen because as you get in altitude, there's less and less oxygen in the air. Therefore, the flight altitude of civil airliners should not be too high, if it is too high, it is possible to make the oxygen in the aircraft less and less, and it will also put the aircraft under greater pressure, and there may be some safety accidents. It is very dangerous in the air, and we must ensure the safety of our passengers and not let them have problems.

And there are oxygen inhalation equipment in the plane, and if there is a lack of oxygen, you can inhale oxygen.

Under normal circumstances, civil airliners can fly at an altitude of several thousand meters and reach a maximum of 10,000 meters, otherwise there will be danger.

Between 6 kilometers and 12,000 meters, this altitude is still very high, and the higher you fly, the thinner the air will be, and this altitude is unbearable for ordinary people.

Under normal circumstances, civil airliners fly at an altitude of more than 6,000-13,000 meters, with different travel distances and flight altitudes.

In general, commercial airliners fly at altitudes between 6,000 and 12,600 meters.

The flight altitude of the fighter is relatively high.

The take-off and landing stages of civil airliners are in the troposphere, and in the stratosphere, they are both cruising stages and aircraft level flights. Because the ceiling of civil airliners is not high, and there is still a certain gap with fighter jets, civil airliners generally cruise at an altitude of about 10,000 meters.

The ultimate altitude of the third-generation fighter is generally 15,000 meters - 20,000 meters. And the second-generation fighter that pursues high altitude and high speed, represented by the Soviet MiG-25, is capable of flying up to 37,650 meters.

The approximate flight altitude range of modern fighters (i.e. fighters) is 9000-20000m.

Due to the use and material of the general fighter plane, the general ceiling is 20,000 meters, and some special-purpose aircraft can fly to more than 30,000 meters.

<>1. Passenger planes generally fly between 6800-8000 meters.

2. According to the regulations of China's civil aviation industry, civil aviation aircraft above medium-sized are flying at high altitude, and the high altitude here refers to the space at an altitude of 7,000 to 12,000 meters. If the flight altitude layer altitude is less than 8,400 meters (inclusive), every 300 meters is a flight altitude layer; The flight altitude layer altitude is more than 8400 meters (exclusive), and every 600 meters is a flight altitude layer. When the aircraft is flying relatively, crossing, and overtaking, it must maintain a vertical interval of not less than the number of meters at the specified altitude, so as to ensure the safety of hail imitation and smooth traffic.

In addition, the activity area of small aircraft is generally below 3000 meters.
