Remember:
Prior to engaging Navigator mode, a route must be programmed into the GPS
for the Autopilot to follow.
No GPS Data Alarm
If the autopilot is not receiving valid information while in GPS Mode, the No
GPS Data alarm will sound, and "NO GPS" will blink on the display. This
counld be caused by:
Incorrect wiring of the GPS to the KAP-866.
Incorrect data output from the GPS unit.
No route set up or selected in the GPS unit.
No location fix at the GPS unit.
The bearings generated by the GPS unit must correspond to the bearings the
KAP-866 is receiving from its magnetic compass. The greater the difference
between these Bearings, the less accurate will be the Navigator mode steering.
Ensure that the GPS unit has the correct magnetic correction factor.
Ensure that the KAP-866 compass is correctly aligned and installed.
