Aerodrome Flight Information Service (AFIS) is a part of ATS system in Finland and the units providing this service are called AFIS units. AFIS is available at those aerodromes in Finland, where the type and density of the air traffic does not require controlled airspace and ATC.

The purpose of AFIS is to provide information necessary for the safe and efficient conduct of flight operations in the vicinity of the aerodrome and in the maneuvering area.



At some AFIS aerodromes, ATC service may at times be provided instead of the AFIS service. This arrangement can be either permanent (AIP, AD 2) or temporary (AIP SUP). The information concerning the operational hours and the status of the service are given in NOTAMs.

The AFIS unit:

-          provides traffic information and other essential information (meteorological information, aerodrome conditions, etc.),
-          relays air traffic control clearances and route information issued by ATC units (Helsinki Control),
-          suggests runway in use for take-off and landing,
-          provides aircraft parking instructions if necessary,
-          provides alerting service.

 Specific RTF for AFIS units
… when suggesting the most suitable runway for departing or arriving aircraft:
a)      [FI] (kutsumerkki) suositeltava kiitotie (tunnus)
       [EN] (call sign) preferred runway (number)

… when AFIS unit informs the runway is free of traffic:
b)      [FI] (kutsumerkki) [liikenneilmoitus] (tuuli) kiitotie (tunnus) vapaa
       [EN] (call sign) [traffic information] (wind) runway (number) free

… when AFIS unit relays air traffic control clearances:
c)       [FI] (lennonjohtoelin) selvittää (kutsumerkki)…
       [EN] (name of unit) clears (call sing) to…

The AFIS unit requests Helsinki ACC for a route clearance / route information to be forwarded to the aircraft.
When a departing IFR aircraft is ready to depart, AFIS unit has to ask departure permission from the next ACC unit:

"Approval request (aircraft call sign) estimated departure from (significant point) at (time)."
