Readouts 4 and 5

Bearing

Bearing is the direction to a destination waypoint measured

 

in degrees from North (i.e. 321°, where 000° is North, 090°

 

East, 180° is South, 270° is West).

CMG/SMG

Course Made Good/Speed Made Good.

 

Course Made Good is the angle between the starting point

 

on a route and the current position of the boat. The goal is

 

to have CMG and Track equal to the same number. See the

 

Course Made Good illustration. Speed Made Good is the

 

distance from the starting waypoint on the route divided by

 

the time elapsed since starting navigation on the route.

Off

Suppresses the readout so that no data shows in that position.

TRK/CMG

Track/Course Made Good.

 

The Track is the desired line of travel between two

 

waypoints, and represents the most efficient path between

 

the two points because it is a straight line. The TRK is

 

measured in degrees. See above for an explanation of

 

Course Made Good.

TTG

Time To Go.

 

Time To Go is the estimated time required to reach the

 

destination waypoint. TTG is calculated using the SOG and DTG.

VMG

Velocity Made Good.

 

Velocity Made Good is the speed of travel relative to the next

 

waypoint on the route. The goal is for VMG to equal Speed.

WPTend/ETA/DTG

Waypoint End/Estimated Time of Arrival/Distance to Go.

 

Waypoint End is the last waypoint on the route. Estimated

 

Time of Arrival is the estimated time of arrival to the last

 

waypoint on the route. Distance To Go is the distance

 

between the current position of the boat and the last

 

waypoint on the route.
