- 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.
- B. Flight Data
- 1. Obtain a New or Blank CF Card.
- 2. Copy to the New or Blank CF Card the Appropriate Header File.

SYSTEM DESCRIPTION AND INSTALLATION MANUAL
T
3
CAS/Part No.9005000
● If the T
3
CAS is operational, the T
3
CAS P/F Status green annunciator comes
on for a 10-second display period and then goes off.
● If the T
3
CAS is not operational, one or more of the amber fault annunciators
comes on for a 10-second display period.
● An LED test will occur where all LEDs on the T
3
CAS unit will be lit for a
minimum of 1 second in the following colors:
- T
3
CAS P/F STATUS: Red
- Data Status: Amber
- APM Status: Amber
- Top Ant: Amber
- Bot Ant: Amber
- External IO Status: Amber
● During the LED test, the last 10 flight legs will be reviewed for faults. After the
LEDs are illuminated, as described above, if a fault has occurred during the
last 10 flight legs then the LED associated with that fault will be lit for 11
seconds ±1 second.
● During the LED test, all discrete outputs implemented within a specific
aircraft installation will be tested for over current and output voltage levels by
activating the output for 1.5 seconds (±100 milliseconds), then deactivating
the output for 1.5 seconds (±100 milliseconds), and then reactivating the
output for 1.5 seconds (±100 milliseconds). Any faults found will be recorded
in the T
3
CAS unit’s nonvolatile memory.
During the LED test, each time the push-to-test button (on the T
3
CAS unit) is
reactivated, the following will occur in the order presented:
(a) All front LEDs will be lit for 1 second (±0.5 seconds) in the following
colors:
● T
3
CAS P/F STATUS: Green
● Data Status: Green
● APM Status: Green
● Top Ant: Green
● Bot Ant: Green
● External IO Status: Green
(b) The Front Panel LEDs will be set for the fault information of the current
and previous flight legs for a period of 11 seconds (±1 second). The first time the
push-to-test button on the T
3
CAS unit is depressed the active fault information is
displayed. Subsequent activations of the push-to-test button on the T
3
CAS unit
will display faults starting from the current flight leg and then in order from the
most recent (newest) flight leg to the least recent (oldest) flight leg.
(c) If the push-to-test button on the T
3
CAS unit is reactivated during the
display of the tenth previous flight leg fault information (or during the display of
the oldest flight leg stored in the BITE log), then the LEDs on the T
3
CAS unit, will
flash at 2 Hz for 3 seconds and then extinguish, terminating the display mode.
