CAS/Part No.9005000
7 Flight Data Recording
The warning discretes and/or the A429 general output bus may be
connected to the Flight Data Recorder (FDR) or Digital Flight Data
Acquisition Unit (DFDAU).
The TCAS function contains an interface for an ARINC 429 flight
data recorder. The flight data recorder function is activated by
grounding a discrete input pin (RMP-11D) on the rear connector.
With the discrete input grounded, flight data is output as high-speed
ARINC 429 data on the RA Display No.1 and No.2 busses. With the
discrete grounded, the normal RA Display bus operation is not
available.
The TCAS function contains 12 discrete outputs connected to an
ARINC 573 flight data recorder. The outputs are used to record
information during a resolution advisory event.
8 Air Data Interface
The TAWS/RWS function uses Vertical Speed, Static Air
Temperature, Computed Air Speed, and Corrected/Uncorrected
Barometric Altitude from an air data system. In addition, TAWS/RWS
uses True Airspeed (TAS) on installations where T
3
CAS is
performing the RWS function.
The TAWS/RWS function accepts up to three digital ARINC 429
inputs from Digital Air Data Systems. Some of the supported system
interfaces include ARINC 706 Air Data Computer (ADC), ARINC 575
ADC, ARINC 738 Air Data Inertial Reference System (ADIRS), and
other non-ARINC standard interfaces that meet the minimum input
signal requirements.
The Air Data source also provides altitude information to the TCAS
and XPDR functions.
9 Inertial Reference Interface
TAWS/RWS function uses Ground Speed, True Track Angle, Flight
Path Angle, Latitude, Longitude, Altitude MSL, Roll Angle, Pitch
Angle, Inertial Vertical Speed, and True Heading from an inertial
system.
Additionally, TAWS/RWS uses Body Longitudinal and Normal
Acceleration on installations where TAWS/RWS is performing the
RWS function.
T
3
CAS accepts ARINC 429 inputs from an ARINC 704 Inertial
Reference System (IRS), ARINC 705 Attitude Heading and
Reference System (AHRS), ARINC 738 Air Data Inertial Reference
System (ADIRS), Global Positioning and Inertial Reference System
(GPIRS) and other non-ARINC standard interfaces that meet the
minimum input signal requirements.
