Loss Of Display - BENDIXKing AeroNav 910 Pilot's Manual

AeroNav 900/880 Series Pilot's Guide
Recommended Pilot Actions:
The pilot's plan of action will vary based on the pilot, aircraft
configuration, phase of flight and other factors. Taking into
account those variations, pilots should consider the following
actions:

Establish safe separation from terrain, traffic and
hazardous weather, using ATC assistance as necessary

If the affected AeroNav is in use for primary nav or com,
transition to secondary GPS or VHF Nav/Com unit(s), if
available

Consider cycling power on the affected AeroNav via the
top left power knob/button

After the flight, notify an BendixKing Service Center or
BendixKing Customer Support to coordinate for a repair
action

LOSS OF DISPLAY

Failure Indication:
The first indication that an AeroNav has experienced a loss of the
display (LCD) is the appearance of a black display but the bezel
backlighting is still present. Assuming the cockpit dimming
control/rheostat hasn't been activated to the dimmest setting and
the display has actually failed, the easiest indication that just the
display has failed is a continued backlighting of the bezel keys.
Functionality Lost:
All the basic functionality is intact (e.g. VHF com and nav radios,
FMS navigation and deviation output, etc.) but is not visible.
Recommended Pilot Actions:

Check the cockpit dimming control/rheostat to ensure it is
not in the "night" position

Use other cockpit displays (e.g. CDI, HSI, etc) for
crosschecking deviation and position

Consider cycling power on the affected AeroNav via the
top left power knob
