progress. When the self test is successfully completed, the
Navigator asks for NavData database confirmation, acquires
position, and then displays the acquired position on the
Navigator's display.
The Navigator is not coupled to an air and fuel data computer.
Manual fuel-on-board and fuel flow entries must be made in
order to use the fuel planning function of the AUX pages.
The GPS Navigator utilizes altitude information from the
altitude encoder's altitude digitizer to enhance altitude
information.
