The destination field, located at the top of the data window, shows your
bearing (BRG) and distance (DIS) to a destination waypoint or to the cursor. It
also displays your crosstrack error (XTK) and turn (TRN) heading to an active
destination. The XTK value is the distance you are off a desired course (left or
right), while TRN represents the direction (left or right) in degrees between
your course over ground (COG) and the bearing to your destination.
The speed and course field, located
below the destination field, displays your
present speed and course over ground
(SOG and COG).
Below the speed and course field are the
arrival and status fields. The arrival field
displays your velocity made good (VMG)
and estimated time enroute (ETE). Your
velocity made good is the speed you are
closing in on a destination along your
desired track, while the ETE represents the
total time left to reach your destination
based on your current VMG.
The status field indicates the operating
mode and map scale currently in use.
The map scale represents the approximate
distance from the top of the map display
to the bottom.
The softkey menu provides you with direct access to the GPSMAP’s route,
waypoint, auxiliary and range/bearing calculation functions.
