Power-Up Sequence
Power-Up Sequence (continued)
If a valid datacard is not installed or the current position is nowhere
near an airport in the database, the display below appears instead for up
to 10 seconds. Again, press SEL to update the current position.
The displayed position is the location of the aircraft when the power
was last turned off; therefore, this position will not normally need to be
edited; however, in order for GPS sensors to initialize, and loran
sensors to select a GRI, the system must "know" its approximate
location.
If the NMC has been removed from the panel for use in Flight
Simulator mode, the display below appears after reinstallation in the
aircraft, and you must enter a reference position before the power-up
sequence will continue. Press SEL to update the current position.
Rotate the Large and Small knobs to edit the values shown below.
Press ENT when the desired position is entered. Resetting the Present
Position (PPos) may be done by updating the latitude and longitude
directly, as shown below, or by choosing a reference waypoint as the
current position.
