Page 3-48 Rev. 4
AFMS Section 2.11 Autopilot Coupling Limitations
This section of the AFMS contains one possible limitation:
[a] Lateral coupling only for GPS approaches. Coupling to the vertical path for GPS approaches is
not authorized.
For all autopilots covered by the GTN 6XX/7XX AML STC, no limitations apply in this section and none
should be checked on the AFMS. This section is not included in the VFR GPS Limited Airplane Flight
Manual Supplement for Garmin GTN 6XX/7XX GPS/SBAS Navigation System (P/N 190-01007-A5).
AFMS Section 4.5 Autopilot Coupling
This section of the AFMS contains three possible choices:
[1] This installation prompts the flight crew and requires the pilot to enable the approach outputs just
prior to engaging the autopilot in APR mode.
[2] This installation supports coupling to the autopilot in approach mode once vertical guidance is
available.
[3] The installation does not support any vertical capture or tracking.
For all autopilots listed in the GTN 6XX/7XX AML STC, the appropriate check box for that autopilot is
identified in Table 3-15. The corresponding limitation should be checked in the AFMS.
3.8.3 Autopilot Not Listed in GTN 6XX/7XX AML STC
If an installation has an autopilot interface that is not listed in the GTN 6XX/7XX AML STC, additional
FAA approval is required. However, the AFMS provided with the AML STC should still be used, with
the appropriate limitations specified as described below.
AFMS Section 2.11 Autopilot Coupling Limitations
This section of the AFMS contains one possible limitation:
[a] Lateral coupling only for GPS approaches. Coupling to the vertical path for GPS approaches is
not authorized.
For all autopilots that are not listed in the GTN 6XX/7XX AML STC, limitation [a] applies, unless the
autopilot is approved for interface to the Garmin G500/G600 under the G500 or G600 AML STC.
Additional FAA approval from the Aircraft Certification Office (ACO) is required for a particular
installation to remove the vertical GPS coupling limitations. This section is not included in the VFR GPS
Limited Airplane Flight Manual Supplement for Garmin GTN 6XX/7XX GPS/SBAS Navigation System
(P/N 190-01007-A5).
