6.1
Foreword
The GTN 6XX provides precision vertical guidance as well as lateral and advi-
Getting
sory vertical guidance using its built in GPS receiver for GPS or RNAV approaches.
Started
The moving map pages can also be used as a supplemental aid to situational
Xpdr Ctrl awareness for ILS, VOR, and NDB approaches (and non-precision localizer-based
approaches), but the appropriate radio navigational aid MUST be used for primary
Com/Nav
approach course guidance for non-GPS approaches.
Approaches designed specifically for GPS are often very simple and don't require
FPL
overflying a VOR or NDB. Currently, many non-precision approaches have "GPS
overlays" to let you fly an existing procedure (VOR, VOR/DME, NDB, etc.) more
Direct-To
accurately using GPS.
Proc Many overlay approaches are more complex (in comparison to GPS-only
approaches). The GTN 6XX displays and guides you through each leg of the
Wpt Info
approach — automatically sequencing through each of these legs, up to the missed
approach point (MAP). Approaches may be flown "as published" with the full
Map
transition — using any published feeder route or initial approach fix (IAF) — or
may be flown with a vectors-to-final transition.
Traffic
Phase of flight annunciations are provided on the bottom of the display indi-
cating the current mode of flight.
Terrain
Procedures are arranged around the existing flight plan in the following order:
Weather
Departure, En Route, Arrival, and Approach. For example, Departure waypoints
are inserted before the En Route waypoints in the flight plan and Arrival waypoints
Nearest
are inserted between the En Route waypoints and the approach waypoints. Always
verify that the transition waypoints between each phase are correct.
