Flight Service Stations
A flight service station provides services pertinent to the arrival and departure phases of flight at uncontrolled aerodromes and for transit through a mandatory frequency (MF) area. Services include:
- Flight Information Service Enroute: The exchange of information pertinent to the en-route phase of flight. Air traffic information is not provided.
- Aeronautical Broadcast Service: The broadcast on the Flight Information Service Enroute (FISE) frequency, and on 126.7 MHz, of SIGMET, urgent PIREP and information concerning fuel dumping operations.
- VFR Flight Plan Alerting Service: The notification of Rescue Coordination Centres (RCCs) and provision of communications searches when an aircraft on a VFR flight plan or flight itinerary becomes overdue and needs Search and Rescue (SAR) aid.
- Aerodrome Advisory Service (AAS): The provision of information pertinent to the arrival and departure phases of flight at uncontrolled aerodromes and for transit through an MF area. AAS is provided on the MF and is normally in conjunction with VCS.
- Vehicle Control Service (VCS): The provision, at locations where AAS is provided, of instructions to control the movements of vehicles, equipment and pedestrians on manoeuvring areas of uncontrolled aerodromes. Flight service specialists will normally instruct vehicle traffic to leave the intended runway at least 5 minutes prior to the estimated time of landing or before a departing aircraft enters the manoeuvring area. The specialist will coordinate with the pilot prior to authorizing traffic to operate on the intended runway within less than 5 minutes of the estimated time of landing or the time an aircraft is ready for takeoff.
