I utilize the Flarm range analysis tool a few times each season to make sure that my antenna installation and configuration file are operating adequately. However, I would REALLY like to see a 3D view of my range. 2D is fine as far as it goes for the basic knowledge about horizontal coverage, but I think that better understanding of the vertical arena could be equally important, as thermaling in close quarters often puts other gliders in a blind spot for both parties. If Flarm can help recognize these encounters, we need to be sure that our installation can at least pick up a Flarm signal from above and behind or below and in front. Both are scenarios that can rapidly increase the chances of more than scuffed paint.
