Questions tagged [heading]

A heading is a compass direction, given in degrees (0-359°). It refers to the direction the nose of the aircraft is pointing, which may be different from the direction the aircraft is traveling (called a track). Use this tag for questions relating to the usage of the term heading, but should not be used for general navigation or ATC related questions.
