WebSep 30, 2024 · DME dislayed ground speed (GS) is impacted by slant range. When you're close to the dme station (going directly to/from the station) the displayed GS is less than actual GS. When you are a few miles from the station going directly to/from it the displayed GS and actual GS difference is not functionally significant. WebSep 5, 1998 · Slant range error also affects groundspeed and time-to-station displays when you’reclose to the station. Displayed DME groundspeed drops below actual groundspeed as youapproach the station and then climbs back to normal after you pass it. Displayed DMEtime-to-station may not count all the way down to zero as you fly over the station.
