Mal,
PowerFlarm which seems to be running a year or so
behind schedule will have Flarm and ADSB IN as
well as Mode C/S transponder detection. The Flarm
display will show Flarm and ADSB targets and the
transponder detector gives range (within 5nm on
current PCAS units)and relative altitude(within
+/- 2000 feet) as well as whether the target is
climbing or descending. This actually quite
useful and gives you a potential escape manoeuver in many cases.
The ADSB OUT requires a TSO'd Mode S transponder
and TSO'd GNSS system (expensive), required to be
installed,tested and signed off by a qualified
installer(expensive) and WILL require scheduled
checking by a qualified tester(expensive). This
is orders of magnitude more difficult than the
toy TCAS that is Flarm(it is a toy and will be
regarded as such by the regulator because of the
lack of the 3 aforementioned characteristics).
I think we gave away the argument about power
drain when glider pilots installed colour
displays drawing 0.5 amps or greater continuously.
I'm rolling around the floor laughing at sport
aviation organisations, one of which (GFA)
mandated a collision avoidance system in
contests, protesting mandatory fitment of another
collision avoidance system which potentially at
least, protects all air traffic.
Lots of luck with that fellers!

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 âsafe skyâs for allâ!

CASA Discussion Paper Response - Urgent Action Required
To: GFA Members, Gliding Clubs and Regional Gliding Associations
Urgent Action Required
See the response by
<http://GFA.informz.net/z/cjUucD9taT0yOTU5MTQmcD0xJnU9NTAxNzk0NzQ5JmxpPTEzNTEzMTk/index.html>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
"<http://GFA.informz.net/z/cjUucD9taT0yOTU5MTQmcD0xJnU9NTAxNzk0NzQ5JmxpPTEzNTEzMjE/index.html>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.
