Glossary
Accuracy— Estimated position accuracy in feet or meters.
Advisories and Alerts — all alerting on the MX20 is advisory in nature only. Any alerting must be
accompanied by visual acquisition of the traffic or terrain and no aircraft maneuvering is allowed based
upon data presented by the MX20.
Altitude—Height above mean sea level (MSL).
Back Course — Localizer backcourse approach where the signal on the "back" side of the localizer is
used for alignment to the runway opposite of normal localizer alignment. Without compensation the CDI
would reverse sense.
Bearing —The direction from your current location to a destination.
Coasting — With regard to TIS, coasting indicates that a radar sweep was missed and displayed data is
not the latest.
Course —The direction from your starting location to a destination.
Decluttering— Reduction in displayed elements on the moving map at higher zoom scales.
Distance (Destination)— The "great circle" distance from current location to a Go To destination, or
the final waypoint in a route.
Distance (Next) — The "great circle" distance from current location to a Go To destination, or the next
waypoint in a route.
Elevation — The altitude (height) above or below sea level.
Geo-Referenced — a proper relationship is established between displayed information and real-world
coordinates. For instance, the ChartView charts are geo-referenced because they are correctly oriented on
the map display in relationship to actual coordinates.
Ownship — Your aircraft. A variety of symbols are available to represent your aircraft on the display.
