T
3
CAS/Part No.9005000
(14) Glideslope Deviation (Digital/Analog)
The T
3
CAS Glideslope Deviation input parameter is updated using either
Glideslope Deviation data or MLS Elevation Deviation from one of the following
LRU data sources: ILS, FMS, DFS, MLS or GPS.
The minimum External Sensor input accuracies accepted for Glideslope
Deviation are as follows:
● 0.00455 for ddm < 0.0455
● 10% for ddm < 0.175
● Non-decreasing for ddm < 0.800.
(15) Localizer Deviation (Digital/Analog)
The T
3
CAS Localizer Deviation input parameter is updated using either Localizer
Deviation data OR MLS Azimuth Deviation from the following LRU data sources:
ILS, FMS, DFS and MLS.
The minimum External Sensor input accuracies accepted for Localizer Deviation
are as follows:
● 0.00465 for ddm < 0.0465
● 10% for ddm < 0.155
● 20% for ddm < 0.310
● Non-decreasing for ddm < 0.400.
(a) Analog ILS Input
See Glideslope Deviation Analog ILS Input.
(16) Selected Decision Height
The T
3
CAS Selected Decision Height input parameter is updated using one of
the following LRU data sources: EFIS, MCP or FMS.
If the Decision Height is not available from one of the above LRU sources, the
Decision Height will not be annunciated.
The minimum External Sensor input accuracy accepted for Selected Decision
Height is 1 foot (0.305 meters).
(17) Minimum Descent Altitude
The T
3
CAS Minimum Descent Altitude input parameter is updated using one of
the following LRU data sources: EFIS, MCP or FMS.
The minimum External Sensor input accuracy accepted for Minimum Descent
Altitude is 1 foot (0.305 meters).
(18) Body Longitudinal Acceleration (Digital/Analog)
The Body Longitudinal Acceleration input parameter is only used on installations
where T
3
CAS is performing the RWS function.
