- 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
The Glideslope Inhibit Discrete input is used to inhibit Mode 5 Glideslope alerting.
This discrete would typically be enabled by a Flight Deck switch during back-
course approaches (see ILS Back-Course).
(6) Glideslope Cancel
The Glideslope Cancel Discrete input is typically a Flight Deck switch that is used
to cancel Glideslope alerting when an unreliable Glideslope is expected or when
maneuvering is required during ILS final approach.
(7) Decision Height/Minimum Descent Altitude Selection (DH/MDA)
The DH/MDA Discrete input is used select either the Decision Height or Minimum
Descent Altitude input. The selected DH or MDA is used to determine Altitude
Call-Outs.
(8) Below Decision Height
The Below Decision Height Discrete input is to trigger Altitude Call-Outs.
(9) Aircraft On Ground
The Aircraft On Ground Discrete input is shared between the TCAS and TAWS
functions with separate internal wiring.
(10) ILS Back Course
The ILS Back Course Discrete input is used to indicate that a back-course
landing approach has been selected/detected.
A back-course approach is a landing approach in which the localizer signal lobes
have been reversed. Typically the back-course switch is selected on the Auto-
Pilot control panel and will compensate for the reversal of the localizer radio
beams. Additionally, when Back-Course is selected, the Glideslope radio beams
become invalid (resulting in the Glideslope Inhibit discrete being set).
