I agree - lots of good discussion. =20 I would again emphasize though that nobody has yet put the effort into buil= ding a true Tactical Leeching Tool. Flarm just provides data and a collisi= on warning algorithm which seems to work extremely well for the purpose for= which it was designed. I have been truly impressed at how few spurious wa= rnings I have gotten in either unrestricted or stealth mode. As a safety to= ol, I love it. =20 But, please consider what folks could do IF they put their minds to it. V= isualizing and presenting the Flarm data for tactical advantage has hardly = been tapped at all. Imagine a filtering algorithm that takes in Flarm dat= a from a bunch of gliders. It figures out if this is a "gaggle" (defined = by at least 2 gliders circling for at least 30 seconds and climbing, for ex= ample). Now, imagine that it smooths the climb data from the gliders th= at are identified as Gaggle A with an indication of average climb rate (30 = second, 60 second, duration of climb) as selected by the user. Imagine t= hat another gaggle (Gaggle B) nearby is similarly filtered and displayed. = Color coding is applied with strongest average climbs in Green and decreas= ing in size and intensity with weaker climbs. Also, the user can set aler= ts to indicate if specific targets are in Gaggle A or Gaggle B. Okay, Gag= gle A is clearly averaging a better climb, and as a bonus P7 is part of the= group. This is not 10 years out sort of stuff. I've already written spe= cs for several of these examples. =20 I suspect that the reason a lot of folks are finding Flarm of limited tacti= cal value right now is largely unfamiliarity with the tool combined with Us= er Interfaces which are not yet optimized for competition. My Flarm routin= ely provides 7.5km to 8km range, which is basically a corridor 15km wide (l= eft and right). And contrary to statements made in this thread, many the= rmals are relatively persistent and regenerative. All you have to do to = see this in action is to download competition files from a recent contest a= nd replay the flights in maggot race mode on SeeYou. If you synchronize o= n start time, you can see gliders converging on exactly the same spot often= times 10-15 minutes apart when you shift back to real-time. So, having = a choice of 2 gaggles displayed each of which is only 3 miles away and KNOW= ING which gaggle is the stronger climb is a very real tactical advantage. = Similar examples apply to the pre-start, straight glides, etc.=20 Of course, if everyone has it, then maybe the playing field is again level.= Except that instead of looking out the window and eyeballing other glider= s to figure out which group is climbing better relative to you, you'll be z= ooming in the gain on your Leeching Window. Sort of like good weather rad= ar operators today who know how to identify the really ugly cells vs. the m= ore benign cells. Maybe that's the exciting next frontier? =20 P3 Astute thinking. Flying the computers is the problem for me. |
