What is the minimum distance a pilot must remain from a forest fire?

The minimum distance a pilot must maintain from a forest fire is 5 nautical miles. This regulation is established primarily for safety reasons. Forest fires can create unpredictable smoke and turbulence, which may significantly affect aircraft performance, visibility, and the overall safety of the flight. By staying at least 5 nautical miles away, pilots can reduce the risk of encountering hazardous conditions associated with the fire's heat, smoke, and potential updrafts.

Maintaining this distance also allows for the easier coordination of firefighting aircraft, which often operate in close proximity to the fire zone. This is particularly important to prevent possible collisions or interference between firefighting efforts and general aviation operations. The requirement for the 5 nautical mile distance underscores the importance of situational awareness and adherence to regulations regarding safe flight operations in the vicinity of forest fires.
