Tips on Creating and Using the TracBack FeatureThe GPS 92’s TracBack feature is designed to help youquickly create and activate a route that follows your pathback to a user-defined starting point. To get the most outof the TracBack feature, remember the following tips:• Always clear your track log at the exact point whichyou will want to go back to (airport, landing field,etc.).• The ‘RECORD’ option on the track log setup pagemust be set to ‘WRAP’ or ‘FILL’.• There must be at least two track log points stored inmemory to create a TracBack route.• If there are not enough available waypoints inmemory to create a TracBack route, you will bealerted with a ‘waypoint memory full’ message. Thereceiver will use any available waypoints to create aTracBack route with an emphasis on the track logclosest to the destination (the oldest track log pointin memory).• If the ‘CRITERIA’ option on the track log setup pageis set to a time interval, the TracBack route may notfollow your exact path (keeping the criteria set to‘AUTO’ will always provide the best TracBackroute).• If the changes in direction and distance of yourtrack log are very complex, 30 waypoints may notbe enough to accurately mark your exact path. Thereceiver will then assign the 30 waypoints to themost significant points of your track and simplifysegments with fewer changes in direction.• If you want to save a TracBack route, copy route 0to an open storage route before activating anotherTracBack. Activating another TracBack or storageroute will overwrite the existing TracBack route.• Whenever a TracBack route is activated, the receiv-er will automatically erase any temporary way-points (e.g., ‘T001’) that are not contained in routes1-19. If there are temporary waypoints stored inroutes 1-19, the receiver will create any new tem-porary waypoints using the first three-digit numberavailable.To save a TracBack route,be sure to copy route 0 toanother route. To save atemporary waypoint, sim-ply rename it following theinstructions on page 27.The TracBack functionallows you to navigate yourtrack log back to the oldesttrack point in memory.TracBackNavigationReference32
