The Canada Flight Supplement (CFS) (French: Supplément de vol Canada) is a joint civil/military publication and is a supplement of the Aeronautical Information Publication (AIP Canada). It is the nation's official airport directory. It contains information on all registered Canadian and certain Atlantic aerodromes and certified airports.[1][2]
The CFS is published, separately in English and French, as a paper book by Nav Canada and is issued once every 56 days on the ICAO AIRAC schedule.[1][2]
The CFS was published by Natural Resources Canada on behalf of Transport Canada and the Department of National Defence until 15 March 2007 edition, at which time Nav Canada took over production.
