AeroNav 900/880 Series Pilot's Guide
NOTE
Autopilot Integration
Autopilot integration and capability can vary widely.
BendixKing strongly recommends flying practice
approaches in VMC conditions to understand the
level of integration between the AeroNav and the
autopilot before any flight in IMC conditions. For
example, many roll-steering capable autopilots will
terminate the roll steering capability when approach
mode is selected on the autopilot. As another
example, some autopilots such as the KAP-140 and
the KFC 225 do not support automatic switching to
VLOC; switching the nav mode and entering the in-
bound course must be manual operations with those
autopilots.
In the case of KFC-225 and KAP-140 autopilots,
depending on how the AeroNav was configured, a
prompt is provided when GPS is the nav source to
enable the approach ("Enable A/P Approach" CAS
message displayed which directs a pilot selection
along the left side of the FPL tab). At that point,
APPR mode can then be selected on the autopilot.
This setting will also ignore the GPSVLOC
Capture option on the User Options part of the
Setup tab on the AUX page.
