1 INTRODUCTION

This document provides clarification for the operation of Garmin GNS 400(W)/500(W) and
GTN 6XX/7XX navigators while flying procedures that include heading and altitude-based legs.

The following are best practices for Garmin GNS and GTN systems used for primary navigation guidance
during instrument procedures:

• Before using the GTN or GNS navigation system for primary navigation guidance for any part of
an instrument procedure, always compare each leg of the applicable and current published charted
procedure to the flight plan displayed on the navigator. The navigation system may not support
some specific navigation leg types, it is important to understand how each leg will be navigated
prior to conducting the procedure.

• When a procedure includes navigation legs defined by a specific heading, or that end at a specific
altitude, it is important to understand how the navigation system will behave and how that system
behavior can affect autopilot operations, if coupled.

• Before manually sequencing a leg in a procedure, verify what specific navigation guidance will be
provided by the GNS/GTN for that leg, and activate the leg only upon arrival at the appropriate
point in the procedure.

• Use available documentation, including Flight Manual Supplements, to understand the operation
of the specific GNS or GTN system installed in the aircraft.

• Learn and gain a thorough understanding of instrument navigation operations and general system
behavior on the ground using the GNS or GTN PC Trainer provided free of charge at
