I like Ian's idea. The Flarm radar can serve as a tactical tool. (For example two gliders circling in different thermals 2km ahead. Which one should I be heading for, which has the better lift?) This is what I use it for most of the times.
It can however also be used to improve situational awareness about the gliders in close proximity. Personally I prefer spending more time looking outside and if there is am alert I glance at the FLARM LED-display for a fast cue and then back outside. Nevertheless there might be situations where some additional information is helpful. So I think splitting the FLARM Radar behaviour in a proximity area and an area outside might be a good idea. My suggestion would be Proximity Area: - Instantaneous display - No Filtering or position extrapolation - Prox-Glider-Count displayed (as Ian suggested) - If reception of a target is lost don't show it, however keep it in the Prox-Glider-Count for a longer timespan Tactical Area (outside Prox-Area): - Filtered display - Show Average climbrates (eg. averaged over last 20sec) - Show the targets last position and climb rate even if reception is lost, for a longer timeout (eg. 30 sec) - Maybe extrapolate position for targets in straight flight. I think this should account for the tactical needs as well as the situational awareness.
