IN-FLIGHT RESTART
The KFD 840 is capable of a partial reset in-flight under emergency
conditions. If a power failure occurs or an emergency condition
occurs that warrants the need to reset the system, the pilot should
maintain straight and level flight until the alignment is completed or
as long as possible without compromising the safety of the flight.
If an internal fault is detected, the unit may automatically attempt a
reset.
The pilot must fly using the standby instruments following an in-flight
restart.

Once the unit has repowered in flight, altitude and airspeed
information may return. However the attitude indicator and HSI
information will remain inoperative and in a flagged condition until
the aircraft has landed and the AHRS has been initialized and the
failure condition is eliminated.
Initial power on display brightness is 75% for day and night ambient
lighting conditions.
