Heading — Direction the aircraft nose is pointing, measured in degrees from north.

Heading is the direction in which the longitudinal axis (nose) of the aircraft is pointed, expressed in degrees clockwise from north (001-360). Heading differs from track (the actual path over the ground) when crosswind is present.

Magnetic heading: Referenced to magnetic north (used for flying)
True heading: Referenced to true north (used on charts in polar regions)
Compass heading: Magnetic heading corrected for compass deviation errors
