5.11.6 Map Orientation with Track
If Heading information is unavailable, Track data can be used for Map, Lightning, and Traffic overlays.
Track data comes from the GPS/FMS. Track is the actual direction the aircraft is moving relative to the
earth's surface.
Note:
Avidyne recommends using a Heading reference for the overlay feature. Only use Track if
Heading is not available. Track does not compensate for the “crab” angle of the aircraft.

Values Notes
None The synchro source does not supply a “heading valid” signal, and the EX500/
EX600 will assume the heading is valid whenever an excitation input is detected.
Low means valid The Heading Valid input is active when the signal is LOW.
High means valid The Heading Valid input is active when the signal is HIGH.
