Definition#

A flight plan is a standardized document (ICAO format) filed with air traffic services before departure. It contains aircraft identification, type, route, cruising altitude, speed, fuel endurance, and alternate airport information.

Why It Matters Operationally#

Filing a flight plan is mandatory for IFR and international flights. ATC uses it for traffic management, search and rescue activation, and airspace coordination.
