replaces traditional rotating mass instruments. The GMU 11 Magnetometer uses magnetic field
measurements to create electronically stabilized heading data. The GMU 11 is required when a G5 is
installed as a DG/HSI.
GAD 29/29B
1.6.4
The GAD 29/29B is a light-weight, remote-mount unit that allows interface to IFR navigators such as the
GNS and GTN series. The GAD 29/29B has a 25 pin D-sub connector and a 9 pin D-sub connector.
These connectors provide the following functionality:
•
2 Low Speed ARINC 429 Transmitters
•
4 Low Speed ARINC 429 Receivers
•
1 CAN Network Port
•
*Analog Outputs
•
*Excitation Pass Through
*GAD29B only
For the G5 Attitude and/or G5 DG/HSI installation the GAD 29/29B will receive ARINC 429 data from
the navigators interfaced and transmit that information onto the CAN bus to be consumed by the G5.
The GAD 29/29B can run on 14VDC or 28VDC. The GAD 29/29B can also receive OAT information
over the CAN bus to be converted to ARINC 429 data and transmitted to the navigators.
The GAD 29B contains the same characteristics and function of the GAD 29 as well as providing
autopilot heading and course datum to allow a G5 DG/HSI to be interfaced with autopilots. Reference
section 5.22 and 5.23 for approved autopilot interfaces.
