tested prior to each flight in accordance with the procedures
published herein in order to assure their integrity and continued safe
operation during flight.
A flashing mode annunciation on the face of the autopilot is
normally an indication of mode loss.

An exception to this is HOG annunciation which wi ll flash for
5 seconds along with steady NAVARM , APRARM, or
REVARM annunciation to remind the pilot to set the HOG
bug for course datum use.
1. Flashing HOG -- Indicates a failed heading. PRESS HOG

may be made if the offending navigation flag has cleared.
