The flying height of an ordinary passenger plane is between 6800 and 8000 meters.
According to China's civil aviation regulations, all medium-sized and above civil aircraft are flying at high altitude, and the high altitude here refers to the space with an altitude of 7000 ~12000 m. The flying height is 8400 meters (including the following, every 300 meters is a flying height. The flight altitude layer is above 8400 meters (excluding, every 600 meters is a flight altitude layer. When an aircraft flies, crosses or overtakes, it must keep a vertical interval not less than the specified height to ensure flight safety and smooth traffic.
Causes of stratospheric flight
Flying in the stratosphere, the plane is relatively stable and safe. The stratosphere is cold and warm, and the cold air floats and sinks, so the atmosphere is relatively stable and there is no convection. When the plane flies, it won't bump because of up-and-down convection, but it can also move forward by the horizontal flow of the wind, which is very fuel-efficient. If it is in the troposphere, there are clouds in this place, and there are many convective movements, which are easy to bump and easily lead to plane crashes.
Secondly, the visibility in the stratosphere is relatively high. Because there are relatively few water vapor, suspended solid particles and impurities in the stratosphere, and the weather is clear and the light is good, the visibility will be higher and the flight at high altitude can be seen more clearly. Because it's safer to see clearly.
What is the flying height of civil aviation aircraft?
The flying height of civil aviation aircraft is about10000m.
Civil aircraft usually fly at the top of the troposphere or the bottom of the stratosphere, with an altitude of about 10000 meters (about 30000 feet), and aircraft with good performance will be higher than this altitude. The altitude you choose to fly is related to the length of the route. Flying in the stratosphere when the flight distance is long. Although some flights with shorter routes choose to fly in the upper troposphere, the weather conditions in the upper troposphere are actually relatively stable.
Characteristics of civil aviation aircraft:
1, economy:
The aircraft in cruising state consumes the least fuel per unit distance, and the maximum range of the aircraft is calculated according to the cruising speed, even the transition range of the fighter is calculated according to the cruising speed of the aircraft. Therefore, cruising is the most fuel-efficient part of aircraft flight, which occurs between climbing and descending.
That is, when the plane approaches the destination, enters the descending position and is ready to land, it usually takes up most of the flight time.
2. Comfort:
In flight, with the increase of flight speed, the fuselage will shake violently, which will lead to the violent vibration of the seats in the cabin. The noise of the engine will be greater than that of the ordinary customers' planes, which will make them extremely uncomfortable.
What does the type of airplane mean? What is the difference?
The specific differences are as follows:
1. Small passenger planes have no first class, business class and economy class.
Small passenger planes are generally aircraft, which use propellers or tails to lift the cabin. Single aisle, with two seats on each side, so that passengers can take 20 to 60 people. The flight time is generally less than 3 hours, so the environment is like a bus, and there is no division of first class, business class and economy class.
Medium-sized passenger planes have first class, business class and economy class.
The definition of medium-sized passenger plane is vague, but it should be a high-altitude and high-speed jet plane. Except Airbus A380 and Boeing 747, it is generally called medium-sized passenger aircraft.
Boeing 737 and Airbus A330 are dual-engine, single-channel and dual-channel. These are large and medium-sized passenger planes that usually fly in China. They fly at almost the same altitude and speed. There are first class, business class and economy class, but domestic airlines usually set up more economy class.
Large passenger planes have first class, business class and economy class.
The most typical ones are Airbus A380 and Boeing 747. Both are wide-bodied, with four strokes. There are more than 300 passengers on board. Everything is bigger and more luxurious. It can sail long distances in the ocean.
Comparison of passenger plane size and size;
1. Advantages of large passenger aircraft: large passenger flow and long flight distance.
Disadvantages of large passenger aircraft: generally used in international routes, the price is relatively high and expensive.
2. Advantages of medium-sized passenger aircraft: low requirements for airports, short turnaround and renovation time, and high economy.
Disadvantages of medium-sized passenger aircraft: small passenger capacity and short flight distance.
3. Advantages of small passenger aircraft: low requirements for airports, short transit and transformation time, and the highest economy.
Disadvantages of small passenger planes: few passengers and short flight distance.
Other considerations:
1. The difference between a large passenger plane and a small passenger plane is generally in use, length and width. Small passenger planes include regional planes, such as Xinzhou 60, ERJ 190, CRJ200, etc. Trunk passenger aircraft are divided into large passenger aircraft and medium-sized passenger aircraft.
2. Large passenger planes are generally wide-body passenger planes, such as Boeing 747, Boeing 777, Airbus A380 and Airbus A340. Medium-sized passenger planes are generally narrow-body passenger planes, such as Boeing 737, Boeing 757 and Airbus A320.
Extended data:
Precautions:
A civil airliner is a kind of civil aircraft. Civil aircraft refers to aircraft used for all non-military purposes. Civil aircraft is also called civil aircraft. According to their respective purposes, civil aircraft can be divided into commercial airline aircraft and general aviation aircraft. The largest passenger plane in the world is Airbus A380, with a standard three-cabin layout and 555 seats.
According to different classification standards, passenger aircraft can be divided into the following ways:
Use of aircraft:
Civil aircraft include civil aircraft and national aircraft. National aviation aircraft refers to aircraft used by the army, police and customs. Civil aircraft mainly refers to civil aircraft and helicopters, and civil aircraft refers to civil passenger aircraft, cargo aircraft and passenger and cargo aircraft.
Classification by aircraft engine type;
There are propellers and jets. The history of propeller aircraft includes piston propeller aircraft and turboprop aircraft, and the aircraft engine is piston propeller, which is the most primitive form of power. It uses the rotation of the propeller to push the air to the rear of the plane, and uses the reaction force of the air to push the plane forward. The higher the propeller rotates, the faster it flies.
Jet planes include turbojet engines and turbofan engines. The advantages of this model are simple structure and high speed, with an average speed of 500-600 miles per hour. Save fuel cost and have large cargo capacity. Generally, it can carry 400-500 passengers or100t cargo.
What does a civil aircraft mean?
Civil aviation aircraft refers to all non-military aircraft. Civil aircraft is also called civil aircraft. According to their respective purposes, civil aviation aircraft can be divided into two categories: airline aircraft used for commercial flights and general aviation aircraft used for general aviation.
Civil aviation aircraft refers to a large-scale collective flight transport vehicle with large passenger capacity, which is used for domestic and international commercial flights. Civil aviation aircraft are generally operated by airlines, mainly divided into trunk passenger aircraft and regional aircraft. At present, the world's largest passenger aircraft manufacturers include Boeing, Airbus, Bombardier and Embraer.
