Which air traffic services can be expected within an FIR (flight information region)?

  • A

    AIS (aeronautical information service), SAR (search and rescue).

  • B

    ATC (air traffic control), FIS (flight information service).

  • C

    FIS (flight information service), ALR (alerting service).

  • D

    ATC (air traffic control), AIS (aeronautical information service).

Flight Information Regions (FIR) are those portions of the airspace where it is determined that flight information service (FIS) and alerting service (ALR) will be provided. Flight information regions (FIR) shall be delineated to cover the whole of the air route structure to be served by such regions.

A FIR shall include all airspace within its lateral limits, except as limited by an upper flight information region. Where a FIR is limited by an upper FIR, the lower limit specified for the upper FIR shall constitute the upper limit of the lower FIR and shall coincide with a VFR cruising level of tables in Annex 2. In cases where an upper FIR is established the procedures applicable therein need not be identical with those applicable in the underlying FIR.

A flight information service (FIS) is a form of air traffic service which is available to any aircraft within a flight information region (FIR), as agreed internationally by ICAO.

It is defined as information pertinent to the safe and efficient conduct of flight, and includes information on other potentially conflicting traffic, possibly derived from radar, but stopping short of providing positive separation from that traffic.

Flight Information also includes:

  • Meteorological information
  • Information on aerodromes
  • Information on possible hazards to flight

FIS shall be provided to all aircraft which are provided with any air traffic control (ATC) service or are otherwise known to air traffic service units. All air traffic service units will provide an FIS to any aircraft, in addition to their other tasks.

ALR: Designed and structured to notify and assist organizations associated with search and rescue, Alerting Service is provided to all aircraft receiving ATC service and, as far as practicable, to all other aircraft whose pilots have filed a flight plan or are otherwise known to air traffic services. It is also provided to aircraft known or believed to be subject to unlawful interference. The effect of the alerting service is to set in motion all appropriate rescue and emergency organizations which can provide assistance when and where required.
