All of the improvements that I considered (and more) were already in the unit that I flew with in France! See the report dated 6 September on http://www.users.on.net/~mwilson/vinon2005/   Many thanks for the info - very interesting. I look forward to hearing how the trials go at Gawler. With the reports we have been getting from Europe, it sounds as if FLARM is a truly excellent device. There is only one issue I have with it: if the gliding world in Oz adopts FLARM, how are we going to interface to the rest of aviation (who will be using ADS-B). >From what Migel Andrews has been saying, it is relatively easy to add ADS-B reception to FLARM. This will give the gliding world information about what the rest of aviation is doing in the sky around them, but it won't give the rest of aviation information about the gliders in the sky. Adding ADS-B transmit is a problem in terms of power usage, but I can see another prolem too. If gliders start xmitting ADS-B info (in addition to FLARM), it will be necessary to suppress the ADS-B info from other gliders to prevent alarms going off all over the place in gaggles and such. Having read the article posted here a week or so ago (written by someone in GA I think - I can't find the article in the archive), I am not sure that the rest of the aviation world is quite aware of the problems that ADS-B has for glider operations. -- Robert Hart [EMAIL PROTECTED] +61 (0)438 385 533 Brisbane, Australia http://www.hart.wattle.id.au
