Pre-Flight
  • Deliver the flight plan, NOTAM and aeronautical meteorological information to aviation professionals through AMHS.
  • Receive flight briefing from AISS, including NOTAM and weather briefing for the taking off/landing airports as well as the whole planned flight route.
  • ATMS receives flight plan, NOTAM, aeronautical meteorological information, and presents them to the controller after adequate processing.
  • When the pilot applies for clearance,tower controller issues the clearance verbally through the radio by using the Digital Voice Communication Switching System (DVCSS), or via data communication by using ATMS’s DCL function.
Takeoff
  • Tower controller ensures the separation between aircraft on the ground and vehicles through visual observation or with the aid of ASDE, and issues clearance to the aircraft which is ready to push back and taxi to the runway.
  • Tower controller provides real-time meteorological information by using the control tower’s meteorological equipment and issues takeoff clearance to the aircraft.
  • Under poor weather conditions or at night, switch on the navigation aid lighting equipment along the taxiway and runway to facilitate aircraft operations.
  • After the aircraft has taken off, it is handed over to the approach controller by the tower controller.
Departure / En Route / Cruise / Arrival
  • Approach control and area control are both radar control unit. Approach control is responsible for the taking off and climbing, as well as the arrival and descending of aircraft below 20,000 feet. Area control is in charge of aircraft above 20,000 feet, including most of the level flying and cruising stage.
  • ATMS receive information from the civil/military radar and ADS-B broadcast from the aircraft, compare them with the flight plan data in the system to identify the aircraft and its position in real-time so that the controller can control the aircraft and apply adequate separation.
  • Approach and area controllers maintain contact with the aircraft by radio communication via Digital Voice Communication Switching System (DVCSS), providing flight instructions, weather avoidance and emergency assistance to ensure a safe and smooth traffic flow.
  • ATMS automatically hands over air traffic control information to nearby air traffic control center via AIDC, or the controller will do so verbally via DVCSS.
  • During the flight process, the aircraft will follow the airway constructed by ground NAVAID (VOR, NDB etc.), or rely on RNAV Route navigated by satellite.
Final
  • Approach controller hands over aircraft over to tower controller at 3,000 feet.
  • Tower controller provides real-time meteorological information and issues landing clearance to the aircraft.
  • The aircraft receives a signal from the Instrument Landing System (ILS) and aligns with the runway to land. Under poor weather conditions or at night, tower controller will switch on the approach lights and other navigational aid lighting equipment along the runway and taxiway in order to assist the pilot to land the aircraft.
Landing
  • Tower controller ensures the separation between the aircraft on the ground and vehicles through visual observation or with the aid of ASDE, then instruct the aircraft to the apron.
