SNIP Not trying to be difficult but I must be missing something. If they're that close to you (i.e., within 2 km), they're visible even with Stealth.
From the Flarm documents, V6.0 page 19 (maybe this has changed?):
"Targets with enabled “Stealth Mode” are only displayed..... if they meet at least one of the following requirements:
- target is a threat
- target is within 100m horizontal and 50m vertical
- target is within 2000m horizontal and 300m vertical and within ±45° of own flight track."
So the guys going your way - the ones ND is going to pull up sharply into - you don't even know are there. They aren't a threat because they are paralleling your course. Even if they are close enough to appear, their relative altitude is intentionally wrong.
Now I am going to repeat for the 20th time or so, I don't believe Flarm is a huge increase in safety. It is a big sky and most accidents are spin/stall, not head on. I don't even call my Flarm an anti-collision device, I call it an in-flight entertainment system. But certainly beyond a doubt, it improves situational awareness always, and particularly in the scenario described. On The White Mountains and the Sierra convergence lines, I don't think there have been any head-ons than I can recall. Its a big sky. But plenty of people have had to change their underwear at the end of the day, I can assure you. It was enough of a concern that a rather elaborate procedure was devised in the area, reserving a radio frequency and involving reporting points etc., all of which seemed pretty ineffective, while non-stealth FLARM pretty much solves the problem completely and with no distraction.
i'm not sure.... but think i could miss a glider as i pull if i'm looking right at him dude... you said one glider high left, one low right, so how am i in a position to hit someone if i go high right? especially if i look up in the direction of my pull?? you can't win at hypthetics, because the antagonist can always say, "ok that's fine, but what if..." i'm gonna bow out of this stupid debate now. have the last word if you like. see you dudes!
