From your experience, at about what distance does Flarm give conflict alert in a high speed head on situation? I understand that some gliders show on display at "long" range, presumably before alarms go off by some amount. I'm trying to get a practical understanding of the best case sensing and how it compares with alarming.
Anyone with real world experience, please ring in.
Thanks

UH this is pretty easy to go back and look at using the Flarm range analysis tool. Just use the IGC file for a good ridge day where everyone is doing laps back and forth on the same ridge. My Flarm range is usually around 10km directly out front. I will say it is very nice to get a short beep alert and have the time to look at the target's direction and relative altitude well before getting surprised by a radar warning and having much less time to visually acquire the glider if you don't have them yet (which also happens regularly even while attempting to maintain a good visual scan) Ridge days are where I see a possible issue with the stealth rule here in the east.
