BENDIXKing AeroNav 910 Pilot's Manual page 29

If there is no fuel flow system connected, then the unit
progresses directly to the FMS page and FPL tab, ready
for a flight plan to be entered.
The agreement page, database expiration and fuel management
entries are all skipped if the unit is powered on in-flight.
NOTE
Some Data May Be Delayed At Startup
Some data such as fuel flow and fuel totalizer may
experience a 5-10 second delay during post start
initialization. For those aircraft configured with fuel
totalizers, this may result in some fuel display
changes on the Fuel Mgmt tab during that period
including prompting the pilot to enter in initial fuel.
That should resolve itself within a few seconds.
Another example concerns the FMS nav database
initialization, where the message "Loading nav
database..." may be displayed on any of the FMS
tabs for 10-30 seconds. Additionally, if an AeroNav
910 or AeroNav 905 unit has been exposed to
extreme cold prior to start, it may take a warm up
period to achieve standard performance.
TIPS AND TECHNIQUES
"GPS No Position" Message Possible at Startup
If the GPS alignment takes an unusually long time
(e.g. more than 2 minutes) to acquire an initial
position fix, the "GPS No Position" advisory
message will be displayed. This message will
automatically clear itself when a position fix is
acquired. If the message does not remove itself by
the time you are ready to taxi, it is a clear indication
that your system has not determined its initial
position and action may be required on your part.
