G.4 Autopilots
Autopilots that will be coupled to GPS vertical guidance for GPS approaches must be specifically listed
in the table below.
Autopilots not listed in
482HAppendix G can still be approved under 400W/500W Series AML STC
SA01933LA if all of the following conditions are met:
• The installation of the autopilot was previously FAA-approved;
• All interfaces between the 400W Series unit and the autopilot are analog;
• The installation must use existing navigation signals which interface the autopilot to a standard
VHF navigation receiver (i.e. CDI/HSI L/R and Up/Dn)
• A successful in-air flight check must be completed prior to returning the aircraft to service.
• The AFMS is properly competed, limiting the GPS to lateral coupling only (LNAV)
If these conditions are met the interface can be approved under AML STC SA01933LA. These autopilots
are limited to those operations for which they were previously FAA-approved when interfaced with the
other TC’d or STC’d navigation units (e.g. if the previous unit was installed and approved for coupled
VOR, ILS, LOC, BC and GPS LNAV approaches, this upgraded installation will also be approved for
these operations; however, GPS and RNAV approaches with GPS/WAAS-based vertical guidance
(LNAV+V, L/VNAV and LPV modes on the 400W series unit) are not authorized when coupled to the
autopilot).
NOTE
Contact Garmin to remove VNAV limitations.

If an EFIS is installed, the 400W is
connected to the EFIS using ARINC 429
and the EFIS interfaces to the autopilot.
The 400W is not connected directly to the
autopilot.
