CAS/Part No.9005000
The minimum External Sensor input accuracy accepted is 68 feet per minute
(20.726 meters per minute) when GPS is the source or 30 feet per minute (9.144
meters per minute) when IRS, ADIRS, AHRS or ADC (alternate Baro Altitude
Rate variable) is the source.
(a) Digital Input
T
3
CAS accepts ARINC 429 Vertical Speed inputs from Inertial Systems,
GPS Systems and Digital Air Data Systems (DADC).
IRS systems supported: ARINC 705 Attitude Reference and Heading
System (AHRS), ARINC 738 Air Data Inertial Reference System
(ADIRS), and other non-ARINC standard interfaces.
GPS systems supported: ARINC 743 or ARINC 743A.
DADC systems supported: ARINC 706 Air Data Computer (ADC), ARINC
738 Air Data Inertial Reference System (ADIRS) and other non-ARINC
standard interfaces.
(2) Ground Speed
The T
3
CAS Digital Ground Speed input parameter is updated from a GPS, Flight
Management Systems or Inertial source. GPS/FMS would be the primary source,
an Inertial source would only be used in the short-term during GPS drop-outs.
GPS system supported: ARINC 743/743A.
FMC system supported: ARINC 702 Flight Management System and other non-
ARINC standard interfaces.
Inertial systems supported: ARINC 704 Inertial Reference System (IRS), ARINC
705 Attitude Reference and Heading System (AHRS), ARINC 738 Air Data
Inertial Reference System (ADIRS), ARINC 743A GPS and other non-ARINC
standard interfaces.
The minimum External Sensor input accuracy accepted for Ground Speed is 2
knots from a primary source (GPS/FMS) and 12 knots from a secondary (Inertial)
source.
(3) True Track Angle
The T
3
CAS Digital True Track Angle input parameter is updated from a GPS,
Flight Management Systems or Inertial source. GPS/FMS would be the primary
source, an Inertial source would only be used in the short-term during GPS drop-
outs.
Inertial systems supported: ARINC 704 IRS, ARINC 705 AHRS, ARINC 738
ADIRS, and other non-ARINC standard interfaces.
GPS system supported: ARINC 743/743A.
FMC system supported: ARINC 702 Flight Management System and other non-
ARINC standard interfaces.
