What's the difference between navigation and civil aviation?

The difference between civil aviation airport and general aviation airport;

1, runway construction is different:

Runway navigation facilities in general aviation airports are often relatively simple, and generally do not have the conditions for large civil aircraft to take off and land.

2. Different runway lengths:

The runway of civil aviation airport is long, while that of general aviation airport is relatively short. At present, airports in China are divided according to flight zones. It is represented by a code consisting of "number+letter". The numbers in the first part indicate the runway performance and obstacle limits corresponding to the aircraft performance. The letters in the second part indicate the size of the aircraft, which also determines the required width of the runway and taxiway.

3. The runway looks different:

General aviation airport has no runway, except that the length and width of the runway are relatively small. There is only one apron for helicopters to take off and land. The runway of civil aviation airport is cement runway, but the navigable airport can be grassland, sand, snow and so on.

4. The location of the runway is different:

Civil aviation airports are all on land. There are also mountainous areas that need to level the hills and build airports along the coast. But the general aviation airport is much more flexible. You can take off on land, on the tarmac on the roof, or even in the water.

5, parking the plane is not the same:

Most of the aircraft performing general aviation tasks are small aircraft, light aircraft and helicopters. Civil aviation airport is a designated area for large aircraft to take off, land, taxi, park and carry out other activities.

6, the use is particularly different:

Civil aviation airports mainly undertake the transportation of passengers and goods. General aviation airport carries out pilot training, aerial inspection, aerial mapping, meteorological detection, forest protection, pesticide spraying and other business flights, as well as emergency rescue, commercial charter flights, aerial photography, scenic sightseeing, aerial performances, private flights, short-distance transportation, air movement and other livelihood functions.

Extended data:

Civil aviation airport refers to the designated area used for taking off, landing, taxiing and parking of civil aviation aircraft, including ancillary buildings, devices and facilities. Civil aviation airports are divided into general aviation airports and public transport airports; Excluding temporary airports and special airports.

General aviation airport definitely belongs to civil aviation airport. But it undertakes more other tasks, such as business trip, air travel, meteorological observation, agriculture and forestry spraying, fire patrol, air rescue and other special tasks.

General aviation refers to the use of civil aircraft to engage in civil aviation activities other than public air transport, including flights in industry, agriculture, forestry, fisheries and construction, as well as flight activities in the fields of medical and health care, emergency rescue and disaster relief, meteorological observation, marine monitoring, scientific experiments, education and training, culture and sports.

General aviation industry is a strategic emerging industrial system with general aviation flight activities as the core, covering the whole industrial chain of general aircraft R&D, manufacturing, market operation, comprehensive support and extended services.
