- 7. Downloading Information from the TP3PCAS Using a CF Card
- 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.
- 4. For Flight Data Recording, the aircraft does not need to be in an on-ground configuration.

Radio Altimeter Type Select Program Input No.4 (NO)
The T

CAS computer unit uses radio altitude to inhibit advisories and aural
annunciation when in close proximity to the ground. This analog input No.1, as well
as analog input No.2 can accept data as a dc voltage from several types of radio
altimeters. Program pin RMP-12B is used, along with program pins RMP-12D, -12E,
and -12F, to identify the type of analog radio altimeter installed.
For T

CAS CU ARINC 552, Collins BCA, AHV-6, NR-AS-10A, LPIA, APN-232
CARA and metric type radio altimeters can be selected. The program pin inputs use
ground/open logic levels. All unassigned program pin combinations are invalid and
should not be selected. Pin RMP-6K can be used to supply a ground.
