21. KAP140/KFC225 Autopilot Operation-Compatible
Autopilot outputs for the King KAP140/KFC225
autopilots are activated manually by the pilot after
being prompted during the approach procedure. Since
these autopilots revert to roll mode-wings level when
transitioning to approach mode, it is important for
the pilot to be part of the decision process of when to
make this control change. After enabling outputs, the
400W/500W-series unit will provide guidance informa-
tion to the autopilot.
The 400W/500W-series unit must be configured
during installation to interface with these autopilots.
Guidance to the FAF is active as indicated by Approach
mode annunciation (LPV, L/VNAV, LNAV+V, or LNAV).
See the section on Enabling Autopilot Outputs in the
Procedures chapter of the Pilot's Guide for more details.

25. Installation
The 400W/500W series products are certified with
an AML (Approved Model List) STC. There are more
than 900 aircraft on the approved list. This allows the
aircraft on the AML to be installed via the STC, that may
result in cost and time savings in the installation process
for the aircraft owner. See your dealer for details about
your aircraft installation.
26. How Can I Tell If I Have A WAAS Unit
At the beginning of the start-up screens, the model
number of the unit will have a "W" at the end of the
number.
There are a couple of screens you can check quickly.
The Satellite Status page has changed. Under Status,
the WAAS units will show values for HFOM, VFOM,
and EPU. The SBAS Selection page is only available for
WAAS units; see item 4.
