4.6. Autopilot Integration
The EFD1000 can connect with many dierent legacy autopilot systems that are
typically found in general aviation aircraft. The EFD1000 emulates the HSI and/or
Flight Director (FD) indicator with which the autopilot was originally certied.
Autopilot integration is limited to heading and navigation modes, including vertical
approach modes.
When connected to an autopilot system that includes Nav or Approach couplers, the
EFD also acts as the navigation source selector switch to the autopilot. This assures
that the navigation information presented on the EFD1000 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 installation of the EFD1000 system.
The EFD1000 does not currently provide vertical coupling to barometric references such
as altitude hold, vertical speed, or altitude capture.
See the upcoming Section 4.6.3 Typical Autopilot Operation for additional details
on EFD1000 operation with the autopilot systems during typical aircraft operations,
such as VOR/ILS/GPS approaches.
NOTE
Refer to the autopilot AFMS for
information on the operation of the
autopilot or ight director.
