Canada Flight Supplement

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.

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.

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.

The CFS presents runway data, arrival and departure procedures, air traffic control (ATC) and other radio frequencies and services such as fuel, hangarage that are available at each listed aerodrome. As well, the CFS contains useful reference pages, including interception instructions for civil aircraft, chart updating data and search and rescue information. Most pilots flying in Canada carry a copy of the CFS in case a weather or mechanical diversion to another airport becomes necessary.

The Canada Flight Supplement is made up of seven sections:

Carrying "current aeronautical charts and publications covering the route of the proposed flight and any probable diversionary route" is a requirement under CAR 602.60 (1) (b) for night VFR, VFR Over-The-Top and instrument flight rules (IFR) flights. This Canadian Aviation Regulation (CAR) does not specifically require carriage of a copy of the CFS, but that is one way to satisfy the regulation.
