Which publication would indicate whether an airport has UNICOM?

• A. Aeronautical Information Manual
• B. VNC
• C. Canada Air Pilot
• D. Canada Flight Supplement

Answer: (D)

Knowing whether an airport has UNICOM comes down to where pilots find official airport data. UNICOM is a common-use radio frequency used at non-towered airports to provide advisory information. To check if a specific airport has UNICOM, you look in the official airport directory for the country. In Canada, the Canada Flight Supplement is the definitive source for aerodrome information. It lists each airport’s communications services, including whether UNICOM is available and the associated frequency, along with other essential details like runway data and lighting. This makes it the best publication to confirm UNICOM presence. General guidance publications like the Aeronautical Information Manual cover UNICOM concepts and procedures, but they don’t provide per-airport listings. Visual Navigation Charts show geographic information and airspace but not airport service details. The Canada Air Pilot offers procedures and approach information, not as comprehensive an airport directory as the Supplement.
