Final answer:
A flight plan should be filed with an entity such as a community aerodrome radio station, a flight information center, NAV CANADA, a flight service station, or an air traffic control unit, depending on local aviation regulations.
Step-by-step explanation:
A flight plan should be filed with one of several entities responsible for flight tracking, coordination, and safety. In Canada, these entities might include:
- a community aerodrome radio station,
- a flight information center,
- a flight service station, and
- an air traffic control unit.
However, for an accurate response specific to the area and the type of flight, it is always best to consult local aviation regulations and authorities.
