SYSTEM DESCRIPTION AND INSTALLATION MANUAL
T
3
CAS/Part No.9005000
The T
3
CAS Body Longitudinal Acceleration input parameter is updated from one
of the following Inertial Reference sources: ADIRS, IRS or AHRS.
The minimum External Sensor input accuracy accepted for Body Longitudinal
Acceleration is 0.01-g with 95% confidence.
(19) Body Normal Acceleration (Digital/Analog)
The Body Normal Acceleration input parameter is only used on installations
where T
3
CAS is performing the RWS function.
The T
3
CAS Body Normal Acceleration input parameter is updated from one of
the following Inertial Reference sources: ADIRS, IRS or AHRS.
The minimum External Sensor input accuracy accepted is 0.01-g with 95%
confidence.
(20) Pitch Angle
The T
3
CAS Pitch Angle input parameter is updated from one of the following
Inertial Reference sources: GPIRS, ADIRS, IRS or AHRS.
For T
3
CAS equipped with Windshear, the minimum External Sensor input
accuracy accepted for Pitch Angle is 0.5 degrees with 95% confidence.
(21) Flap Angle
The T
3
CAS Flap Angle input parameter is updated with valid Flap Angle data
from one of the following LRUs: Flap Slat Electronic/Control Unit, Digital Stall
Warning Computer (DSWC), Analog or Discrete.
The minimum External Sensor input accuracy accepted for Flap Angle is 2.0
degrees with 95% confidence or the Discrete value setting.
NOTE:
Most aircraft types have discrete flap settings, where a range of
angles or voltages map into discrete flap settings. For example, 747-
1/2/3 has 7 flap settings with 40-50 degrees range per setting
(22) True Airspeed
The True Airspeed input parameter is only used on installations where T
3
CAS is
performing the RWS function.
The T
3
CAS True Air Speed input parameter is updated from one of the following
Air Data sources: ADIRS or ADC.
The minimum External Sensor input accuracy accepted for True Airspeed is 4.0
knots with 95% confidence.
(23) Angle-of-Attack (AOA) Left/Right
The AOA input parameter is only used on installations where T
3
CAS is
performing the RWS function.
The T
3
CAS AOA input parameter is updated from a Digital Stall Warning
Computer or an Analog Left/Right Angle of Attack Vane source.
