- 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.
- 3. Header files are files copied to the New or Blank CF card that will instruct the computer unit what is desired to be downloaded.

SYSTEM DESCRIPTION AND INSTALLATION MANUAL
T
3
CAS/Part No.9005000
NOTE:
The maximum radio altitude input currently used in TCAS is
+37.5 V dc for a metric system. The common mode ranges
allow for a ±2.5 V dc ground voltage differential
The minimum input impedance on each pin is 95k ohms relative to
ground. The minimum input impedance for inputs which are connected to
both TCAS and TAWS/RWS will be one half the minimum number listed.
(5) Flight Path Angle
The T
3
CAS Digital Flight Path Angle input parameter is updated from an Inertial,
Flight Management or GPS source.
Inertial systems supported: ARINC 704 IRS, ARINC 705 AHRS, ARINC 738
ADIRS, and other non-ARINC standard interfaces.
FMC system supported: ARINC 702 Flight Management System and other non-
ARINC standard interfaces.
GPS system supported: ARINC 743/743A.
The minimum External Sensor input accuracy accepted for Flight Path Angle is
0.3 degrees.
(6) Current Aircraft Weight
The T
3
CAS updates the Current Aircraft Weight from either an FMS or a Weight
and Balance System source.
FMC system supported: ARINC 702 Flight Management System and other non-
ARINC standard interfaces.
The minimum External Sensor input accuracy accepted for Current Aircraft
Weight is 220 pounds (99.79 kilograms) with 95% confidence.
(7) Aircraft Position Latitude/Longitude
The T
3
CAS Aircraft Position input parameter is updated from a GPS or FMS
source. The GPS source can be any one of the following: GPIRS or GPS. In
addition, an IRS source can be used, but only for short periods of time during
GPS or FMS drop-outs
GPS system supported: ARINC 743/743A.
Primary Horizontal Position Sources interfacing with T
3
CAS TAWS must come
from a GNSS source meeting TSO-C129a or any revision of TSO-C145, TSO-
C146, or TSO-C196. As an exception, TAWS equipment intended for installation
in aircraft operating under 14 CFR § 121 may be configurable to operate solely
on a non-GNSS position source.
FMC system supported: ARINC 702 Flight Management System and other non-
ARINC standard interfaces.
