151Appendix GNavigationTerminologyAltitude— Height above mean sea level (MSL).Avg Speed— The average of all second-by-second speed readings sincelast reset.Bearing (BRG)— The compass direction from your present position to adestination waypoint.Course— The desired course between the active ‘from’ and ‘to’ waypoints.Density Altitude— A measure of air density; standard altitude correctedfor temperature and pressure.Distance (Dist)— The ‘great circle’ distance from present position to adestination waypoint.Dist to Dest— The ‘great circle’ distance from present position to aGOTO destination, or the final waypoint in a route.Dist to Next— The ‘great circle’ distance from present position to aGOTO destination, or the next waypoint in a route.ETA— Estimated Time of Arrival. The estimated time you will reach yourdestination waypoint, based on current speed and track.ETA at Dest— The estimated time you will reach a GOTO destination, orthe final waypoint in a route.ETA at Next— The estimated time you will reach a GOTO destination, orthe next waypoint in a route.ETE— Estimated Time Enroute. The estimated time required to reach adestination or the next waypoint in a route.Fuel— The fuel required to travel from present position to the indicatedroute waypoint.Glide Ratio (GR)— The ratio of horizontal distance travelled to verticaldistance travelled.GR to Target— The glide ratio required to descend from present positionand altitude to the target altitude at the location specified in the Vertical Navsettings.Leg Dist— The distance between two route waypoints.
