4.7. Autopilot Integration
1
The PFD can connect with many dierent legacy autopilot systems that are typically
found in general aviation aircraft. Autopilot integration is limited to heading and
navigation modes.
When connected to an autopilot system that includes Nav couplers, the PFD also acts as
the navigation source selector switch to the autopilot. This assures that the navigation
information selected for the PFD is the same as that being provided to the autopilot.
This arrangement also eliminates the need for external autopilot navigation source
selector switches and relays that were previously used to select which navigation radio
would be connected to the autopilot. Selection of autopilot modes and mode control is
unaected by the installation of the PFD.
The PFD does not currently provide vertical coupling to barometric references, such as
altitude hold, vertical speed, or altitude capture.
See Section4.7.3.TypicalAutopilotOperation for more details on PFD operation with
the autopilot systems during typical aircraft operations.
NOTE
Refer to the autopilot AFMS for information on the
operation of the autopilot.
