From the dawn of aviation, pilots required pre-flight planning, although in the earliest flights, this planning was very basic and limited. As the years passed and air traffic steadily increased, the planning procedures grew in both quantity and complexity but were not documented beforehand.

After World War II, various organizations began to emerge to regulate civil aviation, creating different standards and procedures to enhance flight safety. One of the major advancements by these organizations was the creation of a written flight plan form, aimed at documenting all flight information and allowing it to be communicated to various airports involved in the route.

Currently, the International Civil Aviation Organization (ICAO) mandates the submission of a flight plan before commencing any activity. In this work, you will learn everything related to an international flight plan, and you will have the necessary tools to complete it in any flight situation that arises.
