Hello Mal (et al), That device already exists. Its called a "PowerFLARM":
http://www.butterfly.aero/powerflarm/fly/ and/or http://www.lxavionics.co.uk/traffic-monitor.htm This looks like its just about to go into full production. Note that its quoted as being able to run for 8 hours on six AA batteries (or from a glider battery, obviously, as an alternative). i.e. presumably the current draw isn't unreasonable. That doesn't magically solve the economic question, but it does suggest that the actual technology you require here (along with a Mode-S transponder, I guess) is certainly available (or nearly so). I must say that I find the notion of a combination Flarm and ADS-B to be highly appealing as a safety tool. Its eye-opening (literally) to see the thing the ADS-B in my Cirrus picks up before I see them out of the window.

Personally I 100% support technology being used for collision avoidance the cost of the units and current battery technology is minimal and the shared cost per aircraft far out weighs the cost of one life. I am sure that negotiated properly some costs could be shared by GFA and the federal government CASA after all they want “safe sky’s for all”! Mal CASA Discussion Paper Response - Urgent Action Required To: GFA Members, Gliding Clubs and Regional Gliding Associations Urgent Action Required See the response by ASAC to CASA<http://GFA.informz.net/z/cjUucD9taT0yOTU5MTQmcD0xJnU9NTAxNzk0NzQ5JmxpPTEzNTEzMTk/index.html> relating to Discussion Paper 1006AS<http://GFA.informz.net/z/cjUucD9taT0yOTU5MTQmcD0xJnU9NTAxNzk0NzQ5JmxpPTEzNTEzMjA/index.html> In a nutshell, it proposes to mandate universal fitting of ADSB and Mode S to all aircraft for use in all classifications of airspace. This is completely unacceptable to sport aviation generally and gliding particularly. The GFA will be submitting a response which will express similar views to those of ASAC. It is important that as many responses as possible are submitted expressing concerns about the proposal and at the very least expressing strong support for the ASAC submission. Submissions can be made easily by individuals and club representatives via CASA website "Response to Regulatory Change Proposal<http://GFA.informz.net/z/cjUucD9taT0yOTU5MTQmcD0xJnU9NTAxNzk0NzQ5JmxpPTEzNTEzMjE/index.html>". Detailed individual responses would be preferred but a response which just expresses dissatisfaction with CASA's consultation and then notes for each item that changes would make it acceptable, with a final comment supporting the ASAC paper will at least get the message across. It would greatly assist our position if each organisation can ensure a response on their behalf before 30 November and encourage all individual members to do the same. Apologies for the short notice.
