with the global positioning system (GPS) date and time. The date and
time is permitted to be changed when the GPS is failed or does not have
a valid date/time.
The software identifier is displayed at 3L for verification. The software
identifier must be referenced when maintenance action is requested.
The maintenance prompt (6L) is used to verify the FMS system
operating configuration.
