6.1 Foreword Basic Approach Operations The GTN 7XX 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 Audio & awareness for ILS, VOR, and NDB approaches (and non-precision localizer-based Xpdr Ctrl 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 7XX displays and guides you through each leg of the Charts approach - automatically sequencing through each of these legs, up to the missed approach point (MAP). Approaches may be flown "as published" with the full Wpt Info transition - using any published feeder route or initial approach fix (IAF) - or may be flown with a vectors-to-final transition. Map Phase of flight annunciations are provided on the bottom of the display indi- cating the current mode of flight. Traffic Procedures are arranged around the existing flight plan in the following order: Terrain Departure, En Route, Arrival, and Approach. For example, Departure waypoints are inserted before the En Route waypoints in the flight plan and Arrival waypoints Weather are inserted between the En Route waypoints and the approach waypoints. Always verify that the transition waypoints between each phase are correct. Nearest Music Utilities System Messages Symbols Appendix Index 6-2 Garmin GTN 725/750 Pilot's Guide 190-01007-03 Rev. B
