Safe and efficient non-controlled aerodromes

At several non-controlled aerodromes, Aerodrome Flight Information Service (AFIS) is provided to give information to ensure the safe and efficient conduct of flights. The AFIS unit issues information to aircraft moving on the manoeuvring area or apron and in the air, to assist pilots in preventing collision between aircraft and vehicles and obstructions.

The movements of vehicles or pedestrians on the manoeuvring area are subject to authorization by the AFIS unit. Giving meteorological information and information about aerodrome conditions is also included in the duties. The AFIS unit also relays Air Traffic Control (ATC) clearances issued by the ATC unit. At some AFIS aerodromes, a Traffic Information Area (TIA) or a Traffic Information Zone (TIZ) are established to increase safety.
