Aerodrome Flight Information Service AFIS AFIS provides information useful to pilots for the safe and efficient conduct of their flights.
It differs from ATC service in that pilots being provided with AFIS are responsible for assessing a situation based on information passed to them by the FSS and advising their intentions.

AFIS is provided by a FSS at selected non-controlled aerodromes.
In appropriate cases Flight Service Officers may also provide AFIS at controlled aerodromes outside the hours of attendance of ATC.
