In every landing and departure, around 100 systems are involved. This project monitors and controls five of them — the Navigation Aids Sites Control System — alongside standard AC and building control.
- VOR — direction indication
- DME — distance indication
- ILS — landing angle and runway centre point
- NDB — general direction
- DF — direction finding for transmitting aircraft
The control system displays equipment and machine status and alarms, and lets operators enable or disable equipment from the HMI in the main control room.
