The designed control section operation performance comprehensive detection system can be applied to the air traffic control unit and has high application engineering operability.

Description

technical field [0001] The invention relates to the field of aviation, in particular to a method and system for comprehensively detecting the operating performance of an air traffic control sector. Background technique [0002] With the development of the air transport industry, in order to ensure the safety and order of various flight activities, the air traffic control service came into being and was continuously developed and improved until it became mature in the 1980s. The main content of modern air traffic control services is: Air traffic controllers (referred to as "controllers", the same below) rely on modern communication, navigation, and surveillance technologies to manage and control aircraft under their jurisdiction, coordinate and guide their movement paths and Mode to prevent collisions between aircraft in the air and collisions between aircraft and obstacles in the maneuvering area of ​​the airport, and maintain and speed up the orderly flow of air traffic. T...
