FLASHING AMBER MODE ANNUNCIATION
NOTE
Abnormal mode transitions (those not initiated by the pilot or by normal sequencing of the AFCS)
will be annunciated by flashing the disengaged mode in amber on the PFD. Upon loss of a
selected mode, the system will revert to the default mode for the affected axis, either ROL or PIT.
After 10 seconds, the new mode (PIT or ROL) will be annunciated in green.

YAW DAMPER AUTOMATIC DISCONNECT (Amber Flashing ‘YD’)
Flashing amber ‘YD’ in flight indicates that yaw damper has disconnected. If the disconnect was
not pilot initiated, the yaw servo has failed. The autopilot may be re-engaged after a yaw servo
failure.
NOTE
Many King Air 300 aircraft require the yaw damper to be operative above 11,000 feet MSL, and
rudder boost continuously. Refer to the Limitations section of the Aircraft Flight Manual, or
appropriate Airplane Flight Manual Supplement for further information.
