[Flightgear-devel] DME range

2005-10-13 Thread John Wojnaroski
Does anyone know if the DME calculation to a VORTAC is based on slant range? Noticed when flying over a fix say at FL350, the range goes down to zero at station passage. It should be the AGLvalue of the aircraft over the station. OTH a waypoint based on radial intersections or GPS would go to z
