Autopilot Coupling

IFR installations of a Garmin 400W Series unit allow the operator to fly all
phases of flight based on the navigation information presented to the pilot;
however, not all modes may be coupled to the autopilot. All autopilots may
be coupled in Oceanic (OCN), Enroute (ENR), and Terminal (TERM)
modes; however, the FAA requires that vertical coupling of an autopilot for
approaches be demonstrated to meet their intended function and provide safe
and 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 an
ILS (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.

Terrain Display

Terrain refers to the display of terrain information. Pilots are NOT
authorized to deviate from their current ATC clearance to comply with
terrain/obstacle alerts. Terrain unit alerts are advisory only and are not
equivalent to warnings provided by TAWS. Navigation must not be
predicated upon the use of the terrain display.
The terrain display is intended to serve as a situational awareness tool only.
By itself, it may not provide either the accuracy or the fidelity on which to
base decisions and plan maneuvers to avoid terrain or obstacles.
2.9

VNAV

VNAV information may be utilized for advisory information only. Use of
VNAV information for Instrument Approach Procedures does not guarantee
Step-Down Fix altitude protection, or arrival at approach minimums in a
normal position to land.
