(10) Static Air Temperature
The T
2
CAS Static Air Temperature parameter is updated from a Digital ADC or FMS
source.
The minimum External Sensor input accuracy accepted for Static Air Temperature is
4.5 Degrees C, with 95% confidence.
(11) Roll Angle
The T
2
CAS Roll Angle parameter is updated from an Inertial Reference source
(GPIRS, ADIRS, IRS and AHRS).
For a T
2
CAS TAWS only system, the minimu m External Sensor input accuracy for
Roll Angle is 2 Degrees with 95% confidence.
For T
2
CAS equipped with Windshear, the minimum External Sensor input accuracy
Roll Angle is 0.5 Degrees with 95% confidence.
(12) Computed Airspeed
The T
2
CAS Computed Airspeed input parameter is updated from an Air Data
Computer source.
The minimum External Sensor input accuracy accepted for Computed Airspeed is as
follows (with 95% confidence):
• 5kts@60kts
• 2 kts @ 100 kts
• 2 kts @ 200 kts
• 4 kts @ 450 kts
(13) Selected Runway Heading
The T
2
CAS Selected Runway Heading input parameter is updated using either
Selected Runway Heading data OR Selected Course from one of the following LRU
data sources: ILS, MCP or FMS.
The minimum External Sensor input accuracy accepted for Selected Runway
Heading is 2 Degrees.
(14) Glideslope Deviation (Digital/Analog)
The T
2
CAS Glideslope Deviation input parameter is updated using either Glideslope
Deviation data or MLS Elevation Deviation from one of the following L RU data
sources: ILS, FMS, DFS, MLS or GPS.
