FMC Interface
The TAWS/RWS function uses Ground Speed, True Track Angle, Flight Path
Angle, Aircraft Weight, Latitude, Longitude and True Heading from an FMC
system.
TAWS/RWS can accept up to two Digital ARINC 429 inputs from an ARINC
702 Flight Management Computer system or other non--ARINC standard
interfaces.
10
GPS/GNSS
The TAWS/RWS function uses Vertical Speed, Ground Speed, True Track
Angle, Latitude, Longitude, Altitude MSL, WGS 84 altitude and True
Heading from a GPS System.
NOTE: World Geodetic System (WGS) 84 altitude is another type of MSL
altitude.
TAWS/RWS accepts up to two Digital ARINC 429 inputs from an ARINC 743
or ARINC 743A GPS System, or other non--standard ARINC interfaces that
meet the minimum input signal requirements for TAWS/RWS
11
ILS/MLS
The TAWS/RWS function uses Selected Runway Heading, Glide Slope
Deviation, Localizer Deviation, and ILS Select from an Instrument Landing
System (ILS) o r Microwave Landing System (MLS).
TAWS/RWS can accept up to three Digital ARINC 429 inputs from an ARINC
710 ILS receiver, ARINC 727 MLS receiver, or other non-- ARINC standard
interfaces.
TAWS/RWS can accept up to two Analog Glide Slope and two Analog
Localizer inputs from an ARINC 547 or ARINC 578 ILS receiver as a 2--Wire
DC absolute input.
12
Angle Of Attack
On installations where T
2
CAS is performing the RWS function, the
TAWS/RWS function uses the aircraft angle of attack for the Windshear
computation.
TAWS/RWS can accept up to two ARINC 429 inputs from a source such as
a Digital Stall Warning Computer (DSWC) or other data concentrator
devices.
TAWS/RWS can accept analog angle of attack information in the form of
3--Wire AC Synchros, 2--Wire DC absolute and 2--Wire DC ratio--metric
inputs.
