Which flight plan is required for a flight from Canada to Mexico by a standard aircraft?

• A. None, only Tequila
• B. ICAO Flight Plan
• C. ICAO Flight Plan only for commerical aircraft
• D. Transport Canada Flight Plan is sufficient

Answer: (B)

Cross-border flights require a formal international flight plan filed in ICAO format so air traffic services in both countries can coordinate and monitor the route. For a trip from Canada to Mexico, a standard aircraft would still file an ICAO Flight Plan before departure, providing details like route, altitudes, aircraft type, and estimated times. This ICAO plan is the globally accepted format and is what Canadian and Mexican ATC use to manage the flight; a Transport Canada-only filing isn’t a recognized substitute. The option suggesting no plan or a joke option isn’t correct, and the idea that filing is limited to commercial aircraft isn’t true—international flight plans apply to all flights crossing borders.
