4.6.9 GAD 43 Operation
The GAD 43 Adapter may provide attitude, heading, and barometric correction
information from the G500/G600 System to the autopilot. The GAD 43 can also
be configured to provide synchro heading output to other systems and its attitude
output can be used for RADAR stabilization. The GAD 43 has the ability to
disconnect the autopilot if an error in the GAD 43 output or GRS 77 is detected.
This disconnect mechanism must be tested prior to each flight in the following
manner:
1. Upon startup, an AP TEST soft key will be available on the PFD side of
the display.
2. Engage the AP while on the ground.
3. Press the AP TEST soft key and verify that the autopilot disconnects.
CAUTION
Do not use the autopilot if the AP TEST key fails to disengage
the autopilot normally.
NOTE
Pressing and holding the AP TEST key for longer than 1
second will prevent the test from running and the AP TEST
key will remain displayed.
Do not engage the autopilot if advisory “AC Reference Lost” or “Reference
Timeout Fault” is present.
4.6.10 Dual G500/G600 Autopilot Interface
If the installation has dual G500/G600 systems installed, control of navigation
course, heading, or altitude data affecting the autopilot from the co-pilot side can
only be made if the systems are synchronized with each other. Refer to the
Garmin G500/G600 Cockpit Reference Guide for additional information.
4.7 TAWS
At system startup verify that the TAWS SYSTEM TEST audio message is loud
and compelling. Adjust headset volumes as necessary.
4.8 Radar Altimeter
If the installation of the G500/G600 is interfaced to a radar altimeter the radar
altitude can be displayed on the PFD. If the installed radar altimeter includes
self-test capability the Test controls are provided on the AUX/System Setup age.
Refer to the Radar Altimeter user documentation for information about values
displayed during Test. Note, for KRA 405 Radar Altimeters the displayed Test
value will be between 25 and 50ft.
