4--83
(22) Slat Angle
The Slat Angle input parameter is only used on installations where T
2
CAS is
performing the RWS function. Slat Angle data is updated from one of following LRU
sources: Flap Slat Electronic/Control Unit, Digital Stall Warning Computer (DSWC),
Analog or Discrete.
The minimum External Sensor input accuracy accepted for Slat Angle is 2.0 Degrees
with 95% confidence or the Discrete value setting.
NOTE: Most aircraft types have discrete Slat settings, where a range of angles or
voltages map into discrete Slat settings. For example, 747--1/2/3 has 7 slat
settings with 40--50 degrees range per setting.
(23) True Airspeed
The True Airspeed input parameter is only used on installations where T
2
CAS is
performing the RWS function.
The T
2
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 kts
with 95% confidence.
(24) Angle of Attack (AOA) Left/Right
The AOA input parameter is only used on installations where T
2
CAS is performing
the RWS function.
The T
2
CAS AOA input parameter is updated from a Digital Stall Warning Computer or
a Analog Left/Right Angle of Attack Vane source.
The minimum External Sensor input accuracy accepted for AOA is 0.6 degrees with
95% confidence.
(25) Magnetic Heading
The T
2
CAS Magnetic Heading input parameter is updated from one of the following
Inertial Reference sources: ADIRS or IRS.
