>Well, if a flarm-equiped glider 200m away cannot be detected, then I'd assume someone's installation must be really really bad.....
Unfortunately, with a single antenna as all FLARMs except the new "Core" unit have, there is no really good installation in any glider with a carbon fuselage. The best compromise seems to be an antenna position on the panel, but this means that there is almost no transmission in the aft-down direction. Two such gliders in a thermal with some wind drift typically have intermittent FLARM radio contact during circles. >I dont think the issue is with close targets, and I dont think we are talking about long periods of "filtering" in which the glider can drastically change position. We are talking about few seconds, maybe 10 seconds the most, not sure Let´s assume a speed of 40m/s (145km/h or 78kts) for a glider leaving a thermal through the core and 25m/s (90km/h or 50kts) for the glider still thermalling. Relative speed could be up to 65m/s, so in 10s this makes a difference of 650m between filtered / predicted and real position in an example based on typical and by no way extreme speeds.
