There will always be attacks from airspace users who are intolerant of
other users, it's seems to be an ego thing similar to mines bigger, faster

in the area
is in ADSB and I don't believe we should be investing in what will become a
legacy technology, transponders have served aviation well but it's
time to move
forward.
I believe products like Power Flarm will emerge to meet our needs
and the needs
of those we share airspace with and most of will be happy; there
will always be those
who complain.

PowerFlarm is a Flarm with an additional RECEIVER to pick up 1090 MHz
signals from Mode A, C , S and ADSB transponders. Other airspace
users won't be able to see you unless they have a Flarm receiver and
realistically for the heavy metal that simply isn't going to happen.
Glider pilots may be able to fit an uncertified Flarm with velcro to
the top of the instrument panel but Rex or other airlines sure can't.
Even if they were allowed to fit the uncertified equipment the
installation would cost heaps for little benefit at the likely
closing speeds due to the short range, low power Flarm signals. Even
if they got through the heated windscreen with embedded metal film.
Avoiding that problem means external antennas. What was that about
cost? The airlines quite reasonably can say they have bought and
fitted certified equipment for collision avoidance, Transponders ,
ADSB and TCAS and so should everyone else. Gliding simply isn't going
to win this. I doubt any airspace restrictions have ever been avoided
by any actions of official gliding bodies anywhere. There may have
been some small temporary victories but overall a losing battle.
However, in Australia we have actually had a reduction in he inverted
wedding cakes over the main centers. Fitting ADSB OUT to let other
traffic see us is a powerful argument for further reductions in these.
ADSB is best thought of as a super Flarm with range to the horizon.
Yes it requires a transponder that is ADSB capable. The Trig and
others are already Mode A/C/S transponders that can be upgraded to
ADSB OUT with the addition of a suitable GPS datastream. If you fit
such a transponder and convince the authorities about the GPS you are
using (not all GPS units are equal) everyone with a ADSB IN facility
will see you. So will PowerFlarm but if you are transmitting the ADSB
signals at 175 watts vs the peanut whistle 100mW of Flarm you really
don't need the Flarm. I see there are USB stick ADSB receivers to
plug in to a PC for a few hundred dollars. Combination of these with
ADSB out makes a super Flarm that the rest of aviation is already
using or planning on.
