B-2Velocity/time terms:GS Ground speed. GS is the speed measured relative to a groundposition; also known as velocity over ground (VOG).ETA Estimated time of arrival. ETA is the estimated time you will reachthe “active to” waypoint based on current GS. This time is selectableas either UTC or local.ETE Estimated time enroute. ETE is the time it will take to reach the“active to” waypoint based on current GS.Direction terms:DTK Desired track. DTK is the course between the “from” and “to”waypoints. In the case of the GOTO function, the “from” waypointis the location at which the GOTO function was activated.BRG Bearing. BRG is the direction from your present position to the“active to” waypoint.CTS Course to steer. CTS is the recommended direction to steer in orderto reduce cross track error and stay on course. (See Section B.2 foran example using CTS.)TRK Track. TRK is the direction of movement relative to a groundposition.TRN Turn angle. TRN is the difference between BRG and TRK. “L”indicates you should turn to the left, “R” indicate you should turn tothe right. The degrees indicate the angle you are off course.Distance terms:DIS Distance. DIS is the great circle distance from your position to the“active to” waypoint.XTK Crosstrack. XTK is the cross track error, or distance that you are offcourse. If the crosstrack error exceeds the CDI scale setting, theXTK distance will also be displayed on the appropriate side of theCDI.V VNAV altitude. V is the recommended altitude at which you shouldbe in order to accomplish a VNAV maneuver. This information isonly available when the VNAV function has been activated.
