The left screen shows the system affect of the tests results on the
functional areas of the system.
Note – Release 1: Functions that are not part of the installation are not
shown. Release 2.0 or greater: TAS, ATAS, and TAWS are listed with
a “disabled” indication if not installed. FIS-B is removed from the list if
it is disabled.
Note - Individual test failures are recorded in the fault log. (Accessible
to service personnel only.)
The unit returns to normal operation if no failures are detected within
5 seconds.
• If a “Fail” or External Fail” is shown for any of the system functions,
then the message “Self-Test Failure” is shown on the right side of
the display as well as the option to restart the unit or to continue
operation in a degraded mode.
• Tap the “Restart” button to reset the unit and once it is operational,
perform the System Test again. If the failures continue tap the
“Continue” button to proceed in a degraded operational mode.
• If “Degraded” is shown for any of the system functions, then the
message “Service Unit Soon” is shown on the right side of the
display.
• Tap Continue screen button to proceed.
Correct failures before going any further with the functional check.
Note: It is normal to show degraded for certain functions if some
aircraft systems are still aligning, or if the GPS has not yet acquired
a signal.
• On the Transponder Screen, tap the “MSG” button located on the
Transponder Application screen to view fail messages.
• Check signal availability when failures for ADS-B In, FIS-B, GPS,
or TAS are noted.
• Refer to the Chap. 5 (Troubleshooting) for corrective actions.
