(10) Static Air Temperature
The T
3
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
3
CAS Roll Angle parameter is updated from an Inertial Reference source
(GPIRS, ADIRS, IRS and AHRS).
For a T
3
CAS TAWS only system, the minimum External Sensor input accuracy
for Roll Angle is 2 degrees with 95% confidence.
For T
3
CAS equipped with Windshear, the minimum External Sensor input
accuracy Roll Angle is 0.5 degrees with 95% confidence.
(12) Computed Airspeed
The T
3
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):
5 knots @ 60 knots
2 knots @ 100 knots
2 knots @ 200 knots
4 knots @ 450 knots.
(13) Selecting Runway Heading
The T
3
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.
