Hang gliding information for GPSMAP 76S

Glide Ratio(GR) and Glide Ratio to Target(GRT):

To use these properly the values must be compared side by side on two data fields. The GPS must be navigating to a waypoint or route and be above the location to show the GRT. When using a route, it will give the GRT to the last waypoint in the route. The GR field will zero out when climbing. By comparing these two fields you can determine whether the destination will be reached. Notice that the value for GR does fluctuate more in the smaller soaring aircraft like hang gliders and paragliders.

Vertical Speed to Target:

This assists pilots flying to a goal so they arrive without excess altitude. This displays the vertical speed the pilot should fly to reach the goal in the least amount of time.

Manual Route Transition:

One issue for many competition pilots using current GPS systems is the unit will point to the next waypoint in a route before reaching the current waypoint because of automatic route transition. The new manual route transition allows the user to determine when to begin navigating to the next turnpoint. Choose this option under the "Routes" submenu of the "Main Menu". The regular autoroute transition works great in a car if navigating city streets so turns are not missed, but can cause a problem in competition for light aircraft trying to leave a tracklog point within a turnpoint sector (circle around a waypoint). To manually transition on the GPSMAP® 76S you just press the Nav Key and then enter.
