NAVIGATION PAGE
Overview
Whenever a GOTO, MOB, TracBack or route has been activated, the
GPSMAP 175 will provide digital and graphic steering guidance to the
destination with the navigation page. The top half of the nav page features
four user-selectable data fields that display the bearing (BRG) and distance
(DIS) to waypoint, along with your current course (COG) and speed over
ground (SOG). In addition, there’s a moving compass tape to indicate your
cardinal heading. Two additional data fields at the bottom of the page show
the estimated time enroute (ETE) and velocity made good (VMG) to your
destination.
The middle section of the screen provides visual guidance to the waypoint
on a graphic highway display. The line down the center of the highway
represents your desired track, while a graphic indication of the distance and
direction you are off course is shown on a scale at the bottom right of the page.
(The selected scale represents the distance from side to side.) The arrow
pointer below the highway always points to the destination waypoint relative
to the direction you are moving.
