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.
This installation prompts the pilot 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 autopilot does not support any vertical capture or tracking in this
installation.
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.
