How is Aircraft Heading defined?

Aircraft heading is defined as the angle between the longitudinal axis of the aircraft and magnetic north. This heading represents the direction in which the aircraft is pointed at any given time. It is crucial for navigation, as pilots use heading information to determine their course over the ground. The heading is typically measured in degrees, with magnetic north serving as the reference point, allowing for adjustments when course corrections are needed due to wind and other factors.

Understanding the distinction between heading and other flight parameters, such as course or track, is important. While the aircraft’s heading indicates the direction the nose of the aircraft is aimed, other factors like wind can cause the actual ground track of the aircraft to differ from its heading. Thus, using magnetic north as a reference is essential for navigation and maintaining the desired flight path. This clarity in definition supports pilots in ensuring accurate navigation and effective communication regarding aircraft direction.
