Air traffic control service is the core part of air traffic service, which is divided into the following three parts:
1. Area control service: control airline flight;
2. Approach control service: control of take-off and approach flights;
3. Airport control service: the control of activities in the airport area.
Flight information service is usually provided by regional control units, but in some areas, considering the reality of large number of flights and complex composition of flights, special institutions can be set up and specialized personnel can do this work. The most common way to provide information is to automatically broadcast information at the terminal. Air traffic consulting service is an interval service provided as far as possible for aircraft flying in the air traffic consulting airspace according to instrument flight rules. It is regarded as a temporary transition service from flight information service to air traffic control service. During this period, the relevant units have made a lot of preparations for the future transition in terms of personnel and equipment. This service is not available in China at present.
Early warning service, when the plane is in the state of search and rescue, involves the service of giving notice to the relevant units and being assisted by flight attendants. It is not an isolated air traffic service, nor is it the business of specialized agencies, but a service directly provided by the relevant control units in emergency situations such as engine failure, radio communication system failure and cabin pressure loss. Occurred in the air or illegally hijacked.
The basic tasks of air traffic management are as follows:
1. In addition to ensuring air traffic safety, the air traffic control department also undertakes many tasks such as coordinating the use of airspace by various departments, providing air target identification information for the national air defense system, and predicting the invasion of foreign aircraft and domestic aircraft flying into the restricted area without authorization or illegally crossing the national border;
2. Ensure that the flight activities of all aircraft are managed by the ground command and dispatch at any time and carried out in strict accordance with the plan; Make effective use of space to ensure the orderly air traffic; Ensure accurate and safe navigation services and prevent aircraft from colliding with ground obstacles in the air;
3. To provide effective information and intelligence to ensure flight safety, and identify the relevant data and codes of aircraft entering the air traffic control area so as to take necessary measures; Provide information about missing and distressed aircraft when necessary.
To sum up, the purpose of air traffic management is to effectively maintain and promote air traffic safety, maintain air traffic order and ensure smooth air traffic.
