Unit Power Up
The GTN 7XX System is integrated with the aircraft electrical system and
receives power directly from electrical busses. The GTN 7XX and supporting
sub-systems include both power-on and continuous built-in test features that
exercise the processor, memory, external inputs, and outputs to ensure safe
operation.
1.4.1 Start-Up Screens
During system initialization, test annunciations are displayed. All system
annunciations should disappear typically within the first 30 seconds after
power-up. Upon power-up, key annunciator lights also become momentarily
illuminated on the GTN 7XX display bezel.
The splash screen displays the following information:
• Copyright
• Database List and System version
• Instrument Panel Self-Test
Current database information includes valid operating dates, cycle number,
and database type. When this information has been reviewed for currency (to
ensure that no databases have expired), the pilot is prompted to continue.
Databases that are not current will be shown in amber.
