BPage 9 of 162.7 Autopilot CouplingIFR installations of a Garmin 400W Series unit allow the operator to fly allphases of flight based on the navigation information presented to the pilot;however, not all modes may be coupled to the autopilot. All autopilots maybe coupled in Oceanic (OCN), Enroute (ENR), and Terminal (TERM)modes; however, the FAA requires that vertical coupling of an autopilot forapproaches be demonstrated to meet their intended function and provide safeand proper operation to published minimums. This installation is limited to:
No limitations for autopilot coupling.
Lateral GPS coupling (LNAV only). For 430W units: The GS of anILS (VLOC) may be coupled to the autopilot without any limitations.This limitation may be removed after an FAA Flight Test demonstration.Contact Garmin International, Tech Support for additional information.2.8 Terrain DisplayTerrain refers to the display of terrain information.
