What is the ascent altitude of the plane 20 km after takeoff

Under normal circumstances, the plane flies over the urban area at about 3,000 meters, of course, you also need to consider the height of the cloud base and the status of the pilot. If the distance is 20 kilometers, the aircraft should also be kept at an altitude of 1800-2500, and the engine noise on the ground should not be loud, the maximum will not exceed 50 decibels, if it is in the house, it should not be heard.

Generally do not buy a house on the runway extension! 20 km, the height should be above 1000 meters, noise should not be too much of a problem. The point is that aircraft exhaust contains a lot of "lead", which pollutes the air! I am afraid that long-term residence is not suitable.

When the plane takes off and lands, it is the most noisy time, you are 20 kilometers away from the airport, you can't hear it, and you can't hear the sound of the plane on the entry and departure route.

Kunming Wukongba International Airport is more than 6 kilometers away from the center of Kunming, now more than 30 flights take off and land in peak hours, and there are also entry and departure routes through the sky over Kunming, at least 3000 meters above the ground height from the ground, minus the altitude of nearly 1900 meters in Kunming, at least 1100 meters above the ground, but the sound of the aircraft can not be heard in Kunming City.

If you're 20 kilometers away from the airport and you're still worried about noise, that's a bit too much. The people of Kunming can't live anymore.

In general, the noise level of the aircraft will certainly not have any effect during the day. The key is whether the aircraft takes off and lands frequently, and the noise level of the aircraft itself.

I used to stay a few nights near the airport, once on the route, 6 kilometers away, and landed ...... 2 times an hourLarge planes are fine, but smaller regional airliners are not, and they will definitely not be able to bear it for the elderly. Another time was also on the route, 30 kilometers away from the capital airport, and the planes of almost no matter how big or small they were, there was almost no movement at all. Generally speaking, 20 km should be enough.

If you can, you can measure it in decibels. If you want to know the noise impact or the decibel meter is the most reliable.

The maximum altitude at which a 20,000-meter aircraft can fly is 20,000 meters. Flight altitude: refers to the vertical distance from the aircraft in the air to a certain reference horizontal plane.

The "Basic Rules of Flight of the People's Republic of China" revised by the Military Commission in October 2007 stipulates that "the safe altitude of flight is the minimum flight altitude to avoid collision between aircraft and ground obstacles.

1300+ (rotten width - 500).

Answer: The flight altitude is 800m

Medium-sized and above civil aircraft are flying at high altitude, which refers to the space at an altitude of 7,000-12,000 meters. In this space, there are 1 height layer with 1 km, which is divided into 6 altitude layers: 7,000, 8 km, 9 km, 10,000 m, 11,000 km, and 12,000 km.

High-altitude aircraft are only allowed to fly at a given altitude. In addition, when the civil aircraft is flying, the zero degree limit is due south and north, and all aircraft heading to the right (east) fly an even number of altitude 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.

The highest fighter is the Soviet MiG-25, with a practical ceiling of 30,000 meters and a maximum speed of Mach 3 (that is, three times the speed of sound).

The airliner should fly not low, but it will not fly too high, the flight altitude of the airliner is related to the latitude of its flight, the airliner is flying in the stratosphere, the general stratospheric altitude is 10,000 meters, the airliner is about this height, (may fly at an altitude of only 10,000 meters).

It won't fly high, maybe 5,000 meters at most.

The highest-flying aircraft was the American X 15 A research test aircraft. On March 30, 1961, NASA test pilot Joseph Volcker flew the aircraft to an altitude of 10,000 meters, on April 30, 1962 to an altitude of 10,000 meters, and on July 17, he flew to an altitude of 10,000 meters, which was officially approved by the World Aviation Organization as an absolute world record. In doing so, he became the world's first "astronaut to fly an airplane".

Traditionally, airplanes can fly 50,000 meters, and aerospace planes can go even higher into space.

The flight from Chongqing to Guangzhou is at the highest altitude.

1200 + 400-300-500 = 800 (meters).

So, at this time the altitude of the aircraft is 800 meters.

I hope you can adopt it, and if you don't understand, you can ask questions. Thank you.
