direction
The place or point toward which the aircraft is moving or facing. Direction may be expressed as true, magnetic, or compass headings or paths. Various terms used to describe direction are azimuth, bearing, course, heading, and track. Azimuth and bearing as used in air navigation are measured from the north in a clock-wise direction from 001° to 360°. Course is the path to be flown by aircraft, and track is the actual path flown over the ground.
