not have the option to allow entry into the maintenance pages. The maintenance
report performs the same function as the extended self-test but also includes the
aural annunciation of external BITE faults for the past five flight legs. In addition,
the maintenance report will also automatically enter into the maintenance pages.
The extended self-test and maintenance report should be used as a means of
troubleshooting and diagnostic testing. It is not recommended that either test be
initiated while airborne.
NOTE:
TAWS/RWS extended self-test modes are not applicable to T

CAS part
numbers 9005000-10000, -10101, -10202, -10204, or -11203.
The ability to enter into each type of test is based on the BITE_FAULT_AURALS
ACD setting and the activation of the self-test discrete input. If the ACD entry for
BITE_FAULT_AURALS is enabled, it will allow the system to initiate either an
extended self-test or maintenance report. If the ACD entry for
BITE_FAULT_AURALS is disabled, it will only allow the system to initiate a
standard self-test.
(a) Extended Self-Test
Verify that the aircraft configuration indicates On-Ground.
Push TAWS/RWS flight deck self-test pushbutton/switch twice within
a 3-second period to initiate the extended self-test.
The extended self-test aurally annunciates each active external fault
in the BITE Log’s current flight leg.
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.
Set system power to OFF and correct faults by replacing indicated
LRUs or by repairing any faulty wiring harness.
Test system as required after repair.
(b) Maintenance Report
Verify that the aircraft configuration indicates On-Ground.
Push and hold the TAWS/RWS flight deck self-test
pushbutton/switch for a period greater than 3 seconds.
The Maintenance Report operations execute the following in the
order listed: standard self-test, active fault annunciation, and past
fault annunciation.
After the standard self-test and active fault annunciation (extended
self-test) have completed, the past fault annunciation will begin by
identifying the most recent flight leg.
The most recent flight leg and remaining flight legs will be
annunciated as in the following example:
Example for Flight Legs 1 and 2:
“MOST RECENT FLIGHT LEG IS FLIGHT LEG 1” + “EXTERNAL
FAULTS FOR FLIGHT LEG 1” + “FMS 1” + “RTP 9B” + “bus invalid”
