Coupling the Autopilot during approaches
When the CDI source is changed on the GTN, autopilot mode
may change. Confirm autopilot mode selection after CDI
source change on the GTN. Refer to the FAA approved Flight
Manual or Flight Manual Supplement for the autopilot.
Analog only autopilots should use APR mode for coupling to LNAV
approaches. Autopilots which support digital roll steering commands (GPSS)
may utilize NAV mode and take advantage of the digital tracking during LNAV
only approaches.
This installation prompts the flight crew and requires the pilot to enable the
approach outputs just prior to engaging the autopilot in APR mode.
To couple an approach:
Once established on the final approach course with the final approach
fix as the active waypoint, the GTN will issue a flashing message
indication.
Flashing Message Button ............................................................. PRESS
"Enable APR Output" Button ...................................................... PRESS
If coupled, Autopilot will revert to ROL mode at this time.
Autopilot ............................................ ENGAGE APPROACH MODE
This installation supports coupling to the autopilot in approach mode once
vertical guidance is available.
To couple an approach:
Once established on the final approach course with the final approach
fix as the active waypoint, the GTN will enable vertical guidance.
Vertical Guidance ........................................ CONFIRM AVAILABLE
Autopilot ............................................ ENGAGE APPROACH MODE
The installation does not support any vertical capture or vertical tracking.
