How high can an airplane fly??? How high does an airplane generally fly

What type of aircraft to look at! If you ask us about the planes that we generally do to go to China, they can only fly at an altitude of 1w to 2w! If you're going on a plane abroad, fly at a height of 2W!

Different aircraft fly at different altitudes because of their different power plants and their own aerodynamic structures. For example, the practical ceiling of the SR-71 Blackbird is about 30,000m.

The plane is made of oil, it has no auxiliary fuel, so it can only fly within the atmosphere, as it was said upstairs, it can only approach the atmosphere, but it cannot fly out of the atmosphere, otherwise it will lose power! The higher the flight altitude, the closer to the atmosphere, the thinner the oxygen, the worse the power, the smaller the air pressure, and it is also a test for the pilot, if you fly out of the atmosphere, it is the space shuttle, ordinary planes can't reach it!!

It depends on what kind of plane it is, if it's a paper plane, it's only a dozen meters at most.

Now the highest is the American space shuttle "Discovery", which can take satellites into low-earth orbit and can be reused, very NB

No one knows this, you have to look at the aircraft's device and its own aerodynamics.

It depends on what kind of plane it is. Passenger planes generally fly in the stratosphere, and reconnaissance planes and military planes are very engaged.

Airplanes can fly high, high.

Generally, passenger aircraft fly at an altitude between 6,000 meters and 12,600 meters.

When a civil aircraft is flying, it takes the direction of due south and north as the zero degree boundary, and all aircraft heading to the right (east) fly an even number of high-level layers, that is, 8 kilometers, 10,000 meters, and 12,000 kilometers of altitude layers. All aircraft heading to the left (west) fly in the singular altitude layer, i.e. 7 km, 9 km, 11,000 km altitude layer. Aircraft on short-haul routes generally fly at altitudes of 6,000 to 9,600 metres, while aircraft on long-haul intercontinental routes generally fly at altitudes of 8,000 metres to 12,600 metres.

The stratosphere, which runs from 10,000 meters to 50,000 meters above sea level, is called the stratosphere, and the air flow in the stratosphere is mainly horizontal, and the convective phenomenon is weakened. There is basically no water vapor here, and there are few weather changes, so it is especially suitable for airplane flights. And further up are the middle layer, warm layer, and dissipation layer, which are all heights that cannot be reached by aircraft.

Aircraft usually fly at the top of the troposphere and do not enter the stratosphere. Aircraft on short-sail routes generally fly at altitudes of 6,000 to 9,600 metres, while long-haul intercontinental routes typically fly at altitudes of 8,000 metres to 12,600 metres. At present, the maximum flight altitude of ordinary civil airliners will not exceed 12,600 meters, but some business jets can fly at an altitude of 15,000 meters.

The flight altitude layer is divided according to the following criteria:

The true course angle is in the range of 0 degrees to 179 degrees, and the height is from 900 meters to 8100 meters, and every 600 meters is an altitude layer; The height is from 8,900 meters to 12,500 meters, with a height layer every 600 meters; The height is above 12,500 meters, and the state guesses that every 1,200 meters is a height layer.

The true course angle is in the range of 180 degrees to 359 degrees, and the height is from 600 meters to 8400 meters, and every 600 meters is a height layer; The height is from 9,200 meters to 12,200 meters, with a height layer every 600 meters; The height is above 13,100 meters, and every 1,200 meters is a height layer.

The flight altitude layer should be calculated based on the assumption of sea level under standard atmospheric pressure conditions. The true route angle should be measured from the starting point and turning point of the route. The flight altitude layer shall be equipped according to the nature of the mission, the performance of the aircraft, the flight area and the terrain, weather and flight conditions of the route.

Before taking off, the value of the air pressure on the scene shall be adjusted to the fixed index of the barometric altimeter on the aircraft, so that the pointer of the barometric altimeter shall be pointed to the zero position.

Records show that the world's highest-flying aircraft is the X-15A research test aircraft of the United States, which flies at a maximum altitude of 10,000 meters. Generally, the flight altitude of the aircraft is limited to 12,600 meters, which is the top of the stratosphere, and the stratospheric air is gentle, which is more suitable for aircraft flight.

Passengers are not allowed to carry flammable and explosive materials, controlled knives, live animals, and illegal items with odor or defacement on board.

The length, width and height of carry-on items carried on the plane shall not exceed 20cm, 30cm, 40cm, and checked items shall not exceed 40cm, 60cm, and 100cm.

Carry-on items must not weigh more than 5 kg when traveling, and each passenger is entitled to a free checked baggage allowance of 20 kg.
