Be careful what you agree to Mal, ADSB is in no way similar or compatible with flarm.
Flarm uses extremely low power (in the order of 10mW I believe) to work over
distances of a few KM at most.
ADSB mode S is far more power hungry since it is transmitting data almost
continually at ranges limited only by line of site.
You can now monitor airline traffic on your PC from all over the world in real
time using ADSB data picked up by networks of local receivers sharing their
info on the internet.
The bottom line is that ADSB is suitable for power aircraft with on board power
generation not for sailplanes with a couple of 7 A/H batteries.

Subject: [Aus-soaring] ADSB in gliders and sport aviation
Could flarm and ADSB run on a single unit I recall having discussion with Nigel
about this how about your expert opinion?
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”!

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 relating to
<http://GFA.informz.net/z/cjUucD9taT0yOTU5MTQmcD0xJnU9NTAxNzk0NzQ5JmxpPTEzNTEzMjA/index.html>
Discussion Paper 1006AS 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".
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.
