2.2.14 GAD 43/43e Adapter
The GAD 43 adapter is an optional adapter that provides attitude, heading, and yaw input information for
third-party autopilot systems. It also provides a synchro heading output that can be used to provide synchro
heading to other systems.
The GAD 43/43e can provide the following information in analog format:
•
Pitch and roll for the autopilot (synchro)
•
Pitch and roll for weather radar stabilization (50 and 200 mV/degree)
•
Heading (synchro)
•
Yaw rate (100, 200, 333 and 600 mV/degree/sec)
OR
•
The GAD 43/43e can provide an analog baro-correction output like the Honeywell KEA 130/130A
and KEA 346 (P/N 006-0362-0008 through -0011 only) encoding altimeters.
With the GDU 1060/700 in configuration mode, the GAD 43/43e also allows the installer to set the analog
attitude and heading outputs to specific values without the need for removing any gyros and using a tilt
table.
The GAD 43e provides all of the functions of the GAD 43. In addition, it allows the G500/G600 TXi to
receive data from marker beacon receivers, synchro (ARINC 407) ADF receivers, DME systems, and
analog radar altimeters. It also allows the G500/G600 TXi to provide altitude preselect and vertical speed
control to compatible autopilots.
