ACTV WPT - An attempt has been made to modify the position of the “active to” or “active from” waypoint. The GPS 55 will not allow the modifications.
MEM FULL - The waypoint memory is full. You should delete unused waypoints to make room for new waypoints. NEED ALT - The GPS 55 needs altitude input in order to start or continue 2D navigation. Press NAV to enter altitude on the Position Page. NO EMP RT - There are no empty routes available into which another route may be copied. POOR CVRG - The GPS 55 cannot acquire sufficient satellites necessary to provide navigation. PROX ____ - Your craft has penetrated the alarm circle of the proximity waypoint.
APPENDIX B NAVIGATION TERMS B.1 DEFINITIONS This section provides an illustration of and definitions for the navigation terms used in this manual.
Velocity/time terms: GS Ground speed. GS is the speed measured relative to the ground; also known as velocity over ground (VOG). VMG Velocity made good. VMG is velocity in the direction of the desired course. It is the speed at which you are closing on the “active to” waypoint. ETE Estimated time enroute. ETE is the time it will take to reach the “active to” waypoint based on VMG. Direction terms: DTK Desired track. DTK is the course between the “from” and “to” waypoints. BRG Bearing.
B.2 COURSE TO STEER (CTS) Course To Steer is a GARMIN exclusive that recommends an optimal direction to steer that will guide you to the course and proceed efficiently along your route.
As an example, suppose you activate the route illustrated above. The GPS 55 chooses the closest leg with a desired track of 45 degrees but your position happens to be two nautical miles off course. The unit will automatically compute the optimal course to steer (which is 15° in this example). Press the NAV key until the CDI Page is displayed, then select “CTS” on line two and “TRN” on line three. Turn your craft according to the TRN direction until the TRN angle reaches zero.
