Flight Information Service - UK

UK

In the UK this service is provided by a licensed Flight Information Service Officer (FISO), who has been validated at the particular Aerodrome, using the callsign suffix "Information". The authority of an FISO providing a service at an aerodrome resembles a fully qualified controller for aircraft taxiing, but only extends to the provision of an FIS to aircraft landing, taking-off or in flight, within the Area of Responsibility (i.e. the Aerodrome, and Air Traffic Zone (ATZ)).
