- 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
FAULT ISOLATION
1. General
The T
3
CAS Integrated Platform has three optional procedures for fault detection and isolation to
the LRU level. The first option uses the aircraft OMS or central fault display system (CFDS) if the
aircraft is equipped with an onboard maintenance system. The second option uses a digital
interface between the T
3
CAS Computer Unit and the display system (Weather Radar, EFIS, or
multifunction display for TAWS/RWS and VSI/TRA flat panel display or EFIS for TCAS). The third
option uses the annunciators located on the front panel of the computer unit. The annunciators
are activated by a self-test function within the T
3
CAS Computer Unit. Select the procedural option
for fault isolation from Fault Isolation paragraph 3 (Procedure), which is applicable to the type of
aircraft and the equipment installed.
2. Equipment and Materials
NOTE:
Equivalent alternatives are permitted for equipment in this list.
Digital Multimeter – Fluke Model 29, John fluke Mfg Co. Inc., Everett, WA
3. Procedure
A. OMS or CFDS
Fault information can be displayed from an onboard maintenance system when the
aircraft is so equipped. Fault data is accessible only when the aircraft is on the ground.
Faults that occur at any time, on the ground or while airborne, are stored in fault memory
and reported to the OMS or CFDS. All displayed information is in the English language
with abbreviated terms used only as necessary. Refer to the appropriate OMS or CFDS
support manual for fault retrieval procedures.
B. Flight Deck Initiates Self-Test/Fault Display Systems
(1) TCAS
The TCAS display system can be used to display system status and fail
messages in the Flight Deck, making it more convenient to use than the
computer unit front panel annunciators for a quick checkout of the TCAS system.
In contrast with the computer unit self-test, which records and stores faults from
previous flights, the display system test shows only current status and failure
data.
To access the Flight Deck display test modes, do the procedures that follow:
