Anti collision systems for gliders
There's a company in Switzerland manufactures an anticollision system for
gliders called FLARM. A gadget in your glider continuously broadcasts your GPS position over a low power radio. Gadgets in other gliders so-equipped receive the position messages and using an appropriate algorithm to determine if there is any risk of collision. If there is such a risk, a warning sounds and a position indicator shows the sector of the risk. I think the algorithm can track multiple gliders and is smart enough to determine if you are all in the same thermal and so keeps quiet. The website is www.flarm.com. Has anyone out there got any experience of this system and does anyone know if there are alternative self contained systems available (i.e. that don't rely on transponder responses, for example)? |

Hi Simon FLARM is a low-cost collision-warning device for developed and sold by a non-profit organization FLARM Technology, based in Switzerland. Currently (i.e. within half a year) over 500 devices, sold at approx. EUR 550 / USD 600, are already in use in Switzerland and nearby regions and new orders are coming in constantly. FLARM assesses the traffic and obstacles (currently 21k 3D-objects in its database) around you and issues a warning only if danger is imminent. FLARM was designed for being used in small aircraft with a special focus on gliders. The feedback we've got from many pilots was very enthusiastic and positive. FLARM's development was supported by aviation insurers in order to reduce collisions. FLARM is based on a new open standard for cooperative warning devices which was widely discussed and presented by us to the FAI-IGC in early 2004. We are open for 3rd parties to develop compatible devices but so far we're the only product available. Please check our website http://www.flarm.com/index_en.htm for more details. There is a 3rd party experience report in French available on http://www.planeur.net/articles/0409.htm or http://perso.wanadoo.fr/flarm/ Some very convincing videos (incl. sound) are available at: http://www.afg.ethz.ch/Flugberichte/...affic_left.avi http://www.afg.ethz.ch/Flugberichte/...ffic_right.avi http://www.afg.ethz.ch/Flugberichte/...affic_left.avi (courtesy Jéremie Badaroux, Damien Thomas, St. Crépin/France) Pictures are available from: http://www.flarm.com/pics/high_resolution_picts/ http://www.flarm.com/pics/low_resolution_picts/ Further reading is available from: http://www.flarm.com/vfr_collisions_en.pdf http://www.flarm.com/transponder_haaff_en.pdf Kind regards Andrea Schlapbach info(at)flarm.com |

I am very interested in this too, I was just talking to someone from
Honeywell about their research on collision avoidance hardware. I'm giving a short presentation on my midair collision last spring and some of the things I have learned since and wish to pass on. This system sounds like great material to include. Paul "Andrea Schlapbach" wrote in message om...
