Fly the aircraft manually and crosscheck the GDU 620 attitude indication
with the standby attitude indicator and other sources of attitude information
(airspeed, heading, altitude, etc.).
5.4.2 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, and 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.

5.4.3 Altitude Capture (Optional Upgrade)
The GDU 620 altitude bug may be used to automatically capture a selected
altitude with certain autopilots. Refer to the Airplane Flight Manual and
autopilot system documentation for instructions on how to use the altitude
preselect feature, if available.
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.
