Terminology
Appendix G
Leg Fuel— The fuel required to travel from a route waypoint to the next
waypoint (in sequence) in the route.
Leg Time— The time required to travel from a route waypoint to the next
waypoint (in sequence) in the route.
Max Speed— The maximum second-by-second speed recorded since last
reset.
Odometer— A running tally of distance traveled, based upon the distance
between second-by-second position readings. Both the ‘Odometer’ and ‘Trip
Odometer’ are resettable, however the ‘Odometer’ is typically used to keep
track of total distance covered, where the ‘Trip Odometer’ is used to keep track
of shorter point-to-point distances.
Off Course— The distance you are off a desired course in either direction,
left or right. Also referred to as ‘cross-track error’ or ‘course error’.
Ref— Reference Waypoint. Used to create a new waypoint, by specifying
a bearing and distance from an existing (reference) waypoint.
Speed— The current velocity at which you are travelling, relative to a
ground position. Also referred to as ‘ground speed’.
Time To— The estimated time required to reach a GOTO destination or
the next waypoint in a route. Also referred to as ‘estimated time enroute’.
Time to Dest— The estimated time enroute required to reach a GOTO
destination or the final waypoint in a route.
Time to Next— The estimated time enroute required to reach a GOTO
destination or the next waypoint in a route.
Time to VNv— Prior to reaching the initial descent point, ‘Time to VNv’
indicates the time it will take to reach the initial Vertical Nav descent point.
After passing the initial descent point, ‘Time to VNv’ indicates the time to reach
the target altitude at the point specified in the Vertical Nav settings.
To Course— The recommended direction to steer in order to reduce
course error or stay on course. Provides the most efficient heading to get back
to the desired course and proceed along your route.
Track— The direction of movement relative to a ground position. Also
referred to as ‘ground track’.
