CAS/Part No.9005000
When the extended TAWS self test mode becomes active the T
3
CAS will
aurally annunciate:
“TERRAIN AWARENESS EXTENDED TEST START
NOTE:
During extended test, the above aural annunciation will be performed
in place of the standard self-test annunciations.
Upon completion of the Standard Self-Test, the active faults will be annunciated
as follows:
If one or more active external faults exist in the BITE Log, the Extended Test
will aurally annunciate:
“ACTIVE EXTERNAL FAULTS”
Once “ACTIVE EXTERNAL FAULTS” has been aurally annunciated, the
Extended Test aurally annunciates each active external fault in the BITE
Log’s current flight leg with the following information:
Identifies the LRU source (for example FMS 1, ADC 2, etc.)
Identifies the connector (for example RTP, LMP, etc.)
Identifies the pin designation (for example 9B, 10C, etc.)
Identifies the status (for example Bus invalid/unavailable, Discrete
Invalid, etc.).
If there are no active faults present, the Extended Self Test will aurally
annunciate:
“NO ACTIVE EXTERNAL FAULTS”
If the flight deck self-test pushbutton/switch is activated for greater than 3
seconds during the extended self-test, the T
3
CAS will exit the extended
self-test, restore the captain’s and first officer’s TAWS displays back to
normal operation, and aurally annunciate:
“SELF TEST ABORTED”
Upon completion of the aural annunciation of the current external bite faults, the
T
3
CAS will exit extended self-test by aurally annunciating:
“TERRAIN AWARENESS EXTENDED TEST COMPLETE”
Upon exiting the TAWS extended self-test, T
3
CAS will restore the captain’s and
first officer’s TAWS displays back to normal operation.
(3) Maintenance Report
The TAWS Maintenance Report Test Mode provides a flight deck initiated aural
annunciation of all faults for the past five flight legs. The maintenance report
provides the same information as the extended test mode plus the aural fault
annunciation of the past five flight legs and automatic entry into the maintenance
pages. It is recommended that the maintenance report test mode only be
activated while on the ground.
