How are airports classified?

In China, according to the regulations of the Civil Aviation Administration of China, the general airports in China are divided into Class A and Class B according to whether they are open to the public or not, and Class A is divided into three categories according to the number of passengers that can be carried. Details are as follows:

Class A general airport: a general airport open to the public refers to a general airport that allows the public to enter by themselves to obtain flight services or carry out flight activities;

Class B general airports: general airports that are not open to the public, and general airports other than Class A general airports.

Class A general airports are divided into the following three levels:

A 1 General Airport: A general airport that uses more than 10 aircraft for commercial passenger flight activities;

A2-class general airport: A-class general airport that uses 5-9-seat aircraft to carry out commercial passenger flight activities;

A3 General Airport: General airports other than A 1 and A2.

Extended data:

In China, the flight zone can be classified as backward compatible. For example, the 4E-class flight area is the most common airport in China, and it is often used to take off and land 4C-class aircraft (such as Airbus A320 and Boeing 737), which is the most common domestic flight. Generally, when the runway length is less than half (about 1500m), an airplane can take off from the ground or leave the runway quickly by using the connecting road.

When weather and runway length permit, high-grade aircraft can occasionally take off and land in low-grade flight areas. For example, most 4E-class airports in China can reduce the take-off and landing load of 4F-class Airbus A380 aircraft, but this will reduce the runway life, and it is necessary to manually check the runway surface after take-off.

Increasing the runway length is beneficial to avoid running off the runway when landing in bad weather conditions, braking thrust failure or missing the best grounding point, and it is also beneficial to use the remaining runway length to slow down and brake in the case of emergency interruption of takeoff. Increasing the runway width is beneficial to have more room for correction when taxiing deviates from the runway center line, so as to prevent the aircraft from rushing off the runway.
