What are the types of airports, and civil airports can be divided into several levels

Airport airfield class.

The performance of the runway and the corresponding facilities determine what class of aircraft can use the airport, and the airport is classified according to this capability, which is called the airfield class. The airfield level is represented by a two-part code, the first of which is a numeric number that indicates the runway performance and obstacle limits corresponding to the aircraft's performance. The second part is the letters, which indicate the width of the runway and taxiway required by the size of the aircraft, so that for the runway, the first digit of the airfield class indicates the required length of the flight field, and the second letter indicates the maximum wingspan and maximum track width of the corresponding aircraft, and their corresponding data are as follows:

First place. Digit.

Digit. Length of flight field.

1--- less than 800 meters.

2---800 m to 1200 m.

3---1200 meters to 1800 meters.

4---1800 meters or more.

2nd place. Letter.

Letters - wingspan--- wheel base.

a--- less than 5 meters --- less than meters.

b--- 5m to 24m to 6m.

c--- 24m to 36m---6m to 9m.

d--- 36m to 52m---9m to 14m.

E --- 52m to 60m --- 9m to 14m.

At present, most of China's open airport flight area level is above 4D, Xiamen Gaoqi, Fuzhou Changle, Beijing Capital, Shenyang Taoxian, Dalian Zhoushuizi, Shanghai Hongqiao, Shanghai Pudong, Nanjing Lukou, Hangzhou Xiaoshan, Guangzhou Baiyun, Shenzhen Baoan, Wuhan Tianhe, Sanya Phoenix, Chongqing Jiangbei, Chengdu Shuangliu, Kunming Wujiaba, Lhasa Gonggar, Xi'an Xianyang, Urumqi Diwopu and other airports have the highest flight area level 4E

According to the wingspan of the largest aircraft used in the airport flight area and the distance between the outer wheels of the main landing gear, it is divided into six grades: A, B, C, D, E, and F.

Class 4F airports refer to airports with a usable runway length of 3,600 meters or more, a wingspan of the largest available aircraft in the [65m, 80m) zone, and a distance between the outer wheels of the main landing gear of 14 and 16 m under standard conditions.

Class 4E airports refer to airports with an usable runway length greater than or equal to 3,000 meters but less than 3,600 meters, a wingspan of 52 65 meters for the largest available aircraft, and an outboard distance of 9 to 14 meters between the outer wheels of the main landing gear under standard conditions.

Class 4D airports refer to airports with a usable runway length greater than or equal to 2,400 meters and less than 3,000 meters, a wingspan of 36 52 meters for the largest available aircraft, and a distance of 9 to 14 meters between the outer wheels of the main landing gear under standard conditions.

Class 4C airports refer to airports with a usable runway length greater than or equal to 1,800 meters and less than 2,400 meters, a wingspan of 24 36 meters for the largest available aircraft, and an outboard spacing of 6 9 meters between the outer wheels of the main landing gear under standard conditions.

Class 3C airports refer to airports with a usable runway length greater than or equal to 1,200 meters and less than 1,800 meters under standard conditions, and the maximum available aircraft is the same as that of Class 4C airports.

Airports are generally divided into two categories: military and civilian.

Military airports are used for military aircraft to take off, land, park and organize and support flight activities.

The designated area of a civil airport for the take-off, landing, taxiing, parking and other activities of civil aircraft, including ancillary buildings, installations and facilities.

The layout of the airport should be combined with the strengthening of national defense construction, the promotion of national unity, and the development of tourism and other resources. Attention should be paid to the layout and construction of airports in border areas, ethnic minority areas, and especially emerging tourist areas, expand the scope of air transport services, and enhance the national defense function of airports. At the same time, consideration should be given to the full and effective use of aviation resources, and priority should be given to the joint use of military airports or the new layout of joint military and civilian airports when conditions permit.

Airport Use:

l) Industrial aviation: including the use of aircraft for various activities related to industrial and mining industry, specific applications include aerial photography, aerial remote sensing, aerial geophysical prospecting, aviation hoisting, petroleum aviation, aviation environmental monitoring, etc.

2) Agricultural aviation: including aviation service activities for agriculture, forestry, animal husbandry and fishery. Among them, such as forest fire prevention, fire extinguishing, and pesticide spreading, are incomparable to other methods.

3) Aviation scientific research and exploration activities: including the verification of new technologies, the test flight of new aircraft, and the use of aircraft to conduct meteorological and astronomical observation and exploration activities.

4) Flight training: In addition to training air force pilots, the flight activities of schools and clubs that train all kinds of flight personnel.

5) Aviation sports: sports activities carried out by various types of aircraft, such as parachuting, gliders, hot air balloons and model aviation sports.

China's civil aviation airports are divided into five levels, and most people don't know, how many levels of airports are near your home?

Airport classification standards: Class A, Class B, Class C.

Class A general airport: that is, a general airport open to the public, refers to a general airport that allows the public to enter to obtain flight services or carry out flight activities on its own.

Class B general airport: that is, general airport that is not open to the public, refers to general airports other than Class A general airport.

Category C General Purpose Airport: Exclude.

General airports other than Class I and II.

The current state of aviation:

China's general aviation has just started, it is difficult to meet the needs of national economic development, and it is difficult to provide support for China's economic development and transformation. How to promote the development of general aviation is a major topic worth studying. The ineffective use of airspace, the serious shortage of general airports and the serious shortage of pilots have become the three main obstacles hindering the development of general aviation in China.

To develop general aviation, we must first emancipate our minds, change our concepts, and truly realize the important role of general aviation in national economic and social development. The second is to reform the approval system for the use of airspace and the construction of airports.

The nature, management and use of airspace should be clarified by national legislation, airport construction standards and approval procedures should be formulated according to airport categories, and the support for the construction of general airports should be increased, and the shortage of professional and technical personnel should be solved through market-oriented methods.

The airport is generally composed of the following parts: 1. The flight area, including the runway, taxiway, and liaison road; 2. a helipad; 3. Waiting hall; 4. a navigation tower; 5. The ancillary parts of the airport, including aircraft maintenance hangars, parking hangars, refueling systems, etc. In the flight area and apron part, it also includes a navigational lighting system and road markings.

At present, the runways of major airports in the domestic and international civil aviation systems are 3,600 meters long, which can provide large aircraft such as Boeing 747 for take-off and landing. In the second is 3200 meters, 2800 meters, etc., the runway width of the main runway is 45 meters plus more than two ridge edge hard shoulders per vertical boring seepage edge each meter, the total width is 60 meters, this cover is the largest width at present, the general provincial city airport is this width can meet the flight width of all kinds of aircraft, which is related to the lateral size of the aircraft taking off and landing. The taxiway is generally 23 meters wide, and the width of the connecting road is generally the same width as the main runway.

Airport classes, in different locations, are classified differently. Classification Chinese airports are generally divided into five levels: 3C, 4C, 4D, 4E, and 4F.

Category 4F flight area mainly takes off and lands Airbus A380 and other four-engine long-range wide-body super-large passenger aircraft; The 4E class flight area is mainly used for take-off and landing of Boeing 747 full weight. The 4D flight area mainly takes off and lands Boeing-class flight areas, the main take-off and landing Airbus-class flight areas, and the Boeing 733, ERJ, ARJ, CRJ and other short- and medium-range regional airliners.

Elaboration of the concept of airport classification

Airfield class is often used to refer to airport class. The airport flight area is a general term for the structures that adapt to the characteristics of the aircraft and ensure the safety of operation for the ground activities and parking of aircraft, including: runway and lifting belt, taxiway, apron, ground marking, lighting aids and drainage systems.

Airport airfield classes are often used directly to refer to airport classes. The flight area level is not directly equivalent to the length and width of the airport runway, but also related to the strength of the pavement and the friction of the pavement, which are specifically referred to by the pavement class number PCN and the aircraft class number ACN.
