- 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.

CAS/Part No.9005000
ALT TAG
RELATIVE
Indicates current selection on control panel for type of
traffic symbol altitude indication, RELATIVE or FLT
LVL. Default is RELATIVE if no switch is available on
control panel.
(d) RAD/ALT Status Page
Selection of code 0002 displays the RAD/ALT Status page, Figure 6-4.
This page displays the status of the selected radio altimeter interface to
the T
3
CAS.
Figure 6-4: Typical RAD/ALT Status Page
The first information line (line 3) of the RAD/ALT STATUS page indicates
which of the two radio altimeter ports is being used by the T
3
CAS
computer. The T
3
CAS computer attempts to use radio altimeter No.1
first. If it determines this input is invalid, it automatically switches to radio
altimeter No.2.
The current status of the two radio altimeter ports is displayed on lines 5
and 6. If a signal is valid, the radio altitude value is displayed in either
“FT” for English-type altimeters, or “M” for Metric-type altimeters.
If one of the radio altitude signals is determined to be invalid, the altitude
value is replaced by INACT. Radio altitude INACT indicates the radio
altimeter has failed, is not powered, or is not connected.
The radio altimeter input is determined to be invalid if, for an analog radio
altimeter input, 28 V dc valid is not present at T
3
CAS CU pin RMP-2K for
Radio Alt #1 or pin RMP-3C for Radio Alt #2, or for a digital radio
altimeter input, the SSM of the radio altimeter output indicates not valid
or no data is present on the digital bus.
