Flight Data Recording
There is currently no output to the Flight Data Recorder.
6
Voice Audio Outputs
The TAWS/RWS function contains two analog audio outputs that provide
TAWS/RWS aural terrain avoidance advisories and windshear advisories.
The 8--Ohm output has the capability to supply up to 8 Watts RMS into a
speaker. The 600-- Ohm output has the capability to supply up to 80
milliwatts RMS into an audio distribution system.
7
Air Data Interface
The TAWS/RWS function uses Vertical Speed, Static Air Temperature,
Computed Air Speed, Corrected/Uncorrected Barometric Altitude from an air
data system. In addition, TAWS/RWS uses True Airspeed (TAS) on
installations where T
2
CAS is performing the RWS function.
The TAWS/RWS function accepts up to two 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 for TAWS/RWS.
TAWS/RWS can accept analog air data inputs from an ARINC 565 or ARINC
575 Air Data System and other non-- ARINC standard interfaces. Analog
system inputs can be in the form of 2--wire DC absolute, 2--wire DC
ratio--metric, 2-- Wire AC ratio--metric, 3-- Wire AC Synchro, 3--Wire AC
Sine/Cosine.
8
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.
TAWS/RWS accepts up to two Digital 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 for TAWS/RWS.
TAWS/RWS can accept analog inputs for Body Longitudinal and Normal
Acceleration, Pitch and Roll, Magnetic Track, Variation and Heading. The
analog input sources can be 2-- Wire DC Absolute and 3-- Wire AC Synchro.
