Heading; Altitude Capture (Optional Upgrade); Autopilot Navigation - Garmin G500 Reference Manual

PRIMARY FLIGHT DISPLAY (PFD)

Heading

The GDU 620 heading bug may be used in conjunction with the "Heading"
mode of supported autopilots. When the autopilot is in "heading" mode and the
heading bug is adjusted in the normal manner, the autopilot will turn to and
maintain the selected heading. Refer to the Airplane Flight Manual and autopilot
system documentation for instructions on how to use the autopilot heading mode.

Altitude Capture (Optional Upgrade)

Adjust the altitude bug in the normal manner when using the altitude capture
interface. Some autopilot installations support arming and disarming of the
selected altitude using the ALT key on the PFD. The PFD knob window will
indicate when this function is available. The selected altitude may be alternately
armed or disarmed by pressing and holding the ALT key on the PFD bezel.

Autopilot Navigation

The GDU 620 acts as a switching source between the installed navigation
sources (e.g., GPS/VLOC 1-2). The navigation source that is displayed on the HSI
is sent to the autopilot. Refer to the Airplane Flight Manual and autopilot system
documentation for instructions on how to use the autopilot navigation functions.
1) Set your navigation source and HSI to the desired course.
2) Engage your autopilot in navigation mode.
3) Control your autopilot navigation through the navigation source and the HSI.
