- 1. Obtain a New or Blank Compact Flash (CF) card.
- 2. Copy to the New or Blank CF card the appropriate ‘Header File’
- a) Header files are files copied to the New or Blank CF card that will instruct the computer unit what is desired to be downloaded.
- b) Header files needed to download Maintenance Data, Event Data and CRC Part Numbers can be obtained from ACSS Customer Services at +1-623-445-7070 or crc.acss@l-3com.com.
- 3. For downloading Maintenance Data, Event Data or CRC Part Numbers the aircraft does not need to be in an on-ground configuration.
- 4. Apply power to the computer unit.
- 5. Insert the CF card.
- 6. For ACSS part numbers 9005000-10000, -10101, -10202, and -10204 the DATA STATUS LED will UblinkU green once; this indicates the unit recognized that a CF card was inserted.
- 7. For ACSS part numbers 9005000-11203, -11801 and -55801 the DATA STATUS LED will UblinkU green while reading the header file and performing the action defined in the header file.
- 8. Flight Data Recording
- 1. T3CAS part numbers 9005000-10000, -10101, -10202, and -10204 only support FAT16 CF card formatting. T3CAS part numbers 9005000-11203, -11801 and -55801 support both FAT16 and FAT32 CF card formatting.

SYSTEM DESCRIPTION AND INSTALLATION MANUAL

CAS/Part No.9005000
the OMS/CFDIU.
NOTE:
The extended self-test is not applicable for T

CAS part numbers 9005000-
10000, -10101, -10202, -10204, or -11203.
One of the three types of diagnostic testing can be utilized on the T
3
CAS to obtain status
on the system, depending on the users purpose (status report vs. troubleshooting). First,
the standard self-test results in a high-level pass/fail of the unit LRU and overall system
status. The standard self-test also allows an option to enter the maintenance pages upon
completing the standard self-test. The standard test should be used when a quick
confidence check is needed on the TAWS system. Second, the extended self-test
performs the same function as the standard self-test but also includes the aural
annunciation of the active external faults. The extended self-test however, does not have
the option to allow entry into the maintenance pages. Third, 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 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.
The ability to enter into each type of test is based on the BITE_FAULT_AURALS ACD
setting, the activation of the self-test discrete input, and the activation of the OMS self-
test 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.
(1) Standard Test Mode
The standard test mode provides a flight deck initiated functional test of the aural
annunciations, lamp tests, and display activity. The standard self-test can occur
while on the ground only.
The Standard Self-Test is initiated under the following conditions:
● Activating the OMS self-test input
● The ACD entry for BITE_FAULT_AURALS is NOT enabled and the TAWS
flight deck self-test pushbutton/switch transitions from not initiated to initiated
● The ACD entry for BITE_FAULT_AURALS is enabled and the TAWS flight
deck self-test pushbutton/switch transitions from not initiated to initiated.
NOTE:
The standard self-test will be activated regardless of the ACD setting
for BITE_FAULT_AURALS.
Upon activating the Standard Self-Test, the following will occur:
NOTE:
The standard self-test will not be initiated if a TAWS alert is present or
when either the OMS self-test or a flight deck initiated self-test has
already been activated.
NOTE:
The windshear function is not enabled for T
