Aerodrome and area flight information services An aerodrome flight information service (AFIS) provides information to aerodrome traffic, such as the preferred runway, weather conditions, and traffic information.
Information passed to the pilot by an AFIS is not an instruction or a clearance – it is issued to enhance safety.
Milford Sound is an example of an aerodrome where such information is important.
Pilots should not confuse AFIS units with a UNICOM station (present at Ardmore aerodrome) or a base radio.
Of these three, only an AFIS can provide traffic information determined by the observations of the AFIS operators themselves.
UNICOM may not interpret aircraft information and therefore may only relay information from pilot or aircraft operator reports.
