- 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.

CAS/Part No.9005000
● Non-standard conversion parameters. The conversion code in 5) provides a
standard set of conversion operations which can handle many types of inputs
and outputs. However for more complex types of conversions, the non-
standard conversion allows for a number of operations to be performed on
the data. Operations which may be performed include mathematical,
comparison and branching.
● A parameter which is used to determine the location in RAM where the input
data is stored after processing, or data is read prior to output. This allows I/O
data to be mapped into the correct memory locations where GCAM can
access it.
(2) APM (Not applicable for 9005000-10000, -10101, -10202, -10204, or -11203)
For part numbers 9005000-10000, -10101, -10202, -10204, and -11203, all data
typically stored in the APM, will be stored internally.
The T
3
CAS uses an Airplane Personality Module (APM) to hold aircraft specific
configuration data for TAWS and RWS functions. The APM is used in place of
program pin inputs to provide system configuration. The APM is in an ARINC 607
Type II form factor, and is mounted to the aircraft as part of the installation. It
retains configuration data if a T
3
CAS LRU is removed and replaced with a new
LRU serial number.
The APM contains two types of data:
● Aircraft Type Data
● Installation Option Data.
The aircraft type data is produced by ACSS, and contains data that is specific to
each particular aircraft type. It contains performance data for that aircraft which is
used by TAWS and Windshear functions. It also contains I/O configuration data
for the aircraft that defines and configures the interfaces to the aircraft system.
For each aircraft type, a unique Aircraft Type Data file is produced by ACSS that
has a unique part number.
The Installation Option data replaces the function of program pin (strap) inputs,
and allows the installer to customize the operation of the unit at the time of
installation. Types of functions that can be configured include display options,
discrete output options, altitude callout options, aural annunciation volume
control, and other options. For Part Numbers 9005000-10000, -10101, -10202, -
10204, and -11203, all configurations are performed via pin programming.
Operator selectable options are not applicable to these part numbers. A complete
list of Operator Selectable Options is contained in Table 4-7 and Table 4-8.
The programming of the APM includes the Aircraft Type Data and Installation
Option Data, and is accomplished through the RS-232 port on the PDL connector
through a Laptop PC, or a Compact Flash Card. The APM data file that contains
both types of data is generated on a PC with the EDDIT software tool and allows
the selection of the aircraft type and installation options for that aircraft type. The
EDDIT tool builds a file that contains a cyclical redundancy check (CRC) field
around the APM data. With a blank APM installed in the aircraft, the file can be
uploaded to the T
3
CAS unit over the RS-232 port or through a Compact Flash
card. The T
3
CAS will then program the APM.
