If PowerFLARM was a full blown ADS-B IN/OUT system, you would be able to
see all transponder equipped aircraft using the TIS-B data transmitted
from your local ADS-B ground station. But......

The question was about airliners and you will not need ADS-B data out
to see the 1090ES data out from airliners or many of the other
aircraft who (fly above FL180 and so) are all required to equip with
1090ES by 2020. PowerFLARM will do that just fine out of the box.

For one I am glad that Flarm and Butterfly are not stupid enough to go
down that rathole. If you want 1090ES data-out you add a Mode S
transponder. There are many reasons to separate the functions in two
boxes, starting with there is a large market worldwide already for
stand alone Mode S transponders and by decoupling the highly regulated
data-out functions from the data-in functions allows innovative
companies to develop innovative products--just like PowerFLARM. And in
most countries you do not need ADS-B data out to see other ADS-B data
out equipped aircraft - only in the USA. Vendors are going to optimize
products for a worldwide market? I seems Mike Schumann thinks the
answer to everything is more complexity... and this is yet another
awful suggestion. And if PowerFLARM had 1090ES data-out it would cost
thousands of dollars more plus likely require a certified GPS (the FAA
may have closed off any chance of not requiring this by forcing STC
approval-experimental gliders might still get away eith this?) that
currently costs thousands plus for the forseablefuture require an STC
approval for each glider type it is installed in

I think the answer to everything is more complexity????? Adding a 3rd
collision avoidance technology is more complexity. If I was running the
the FAA, we'd have a single ADS-B technology period. That's simplicity.

It seems that Darryl has consumed so much Koolaid that he's starting to
hallucinate.

Mike I focus here on trying to point out what technologies will do and
what they won't and trying to help pilots navigate the reality of a
complex mess of technology. You seem to spend a lot of time dreaming
about what might be if only... Regardless of how impractical or
unlikely for practical market reasons they might be.

The collision concern for most glider pilots is I believe glider-
glider risk. The clear, well proven and logical choice for helping
reduce that risk is for pilots to deploy FLARM asap and stop dreaming
about ADS-B UAT vaporware for glider-glider collision avoidance. I
think folks here can look at the mess around ADS-B right now and
realize that the minimal complexity path to solve that problem is
PowerFLARM (which also provides PCAS and a future path to ADS-B). If
airliners are a concern then add a transponder (right now-it also is
simple, straightforward and just works).

Darryl



Amongst the glider pilots I fly with, glider / GA and glider / Airliner
collision risks are at least as big a concern, if not bigger than glider
/ glider. Only 10% of US pilots fly in contests, where glider / glider
collisions is obviously a very big problem.

The FAA has obviously made a HUGE mess of ADS-B. However, the ground
stations are rolling out. The Navworx ADS-B transceiver is shipping,
and could easily be interfaced to Clear Nav, See You Mobile, etc... if
we could get the soaring community to help get the parties to cooperate.
Obviously the cost of the Navworx unit is higher than we would like,
so the commercial viability of this unit in the glider world remains to
be seen.

Your dismissive attitude towards ADS-B is not helping to get vendors
interested in providing solutions for the glider community. If this is
your intent, then you are doing a great job. I hope you are getting a
nice fat commission check from the FLARM boys.

But you're not running the FAA, the FAA is running the FAA. And the
way they are running it, if Flarm or similar devices were to add ADS-B
out or operate through the ADS-B protocol rather than low-power direct
radio, it would cost them thousands of more dollars, many more amps,
plus interminable certification delays.

It's not happening; Powerflarm is here and now -- you can see the
jets, you get superb collision avoidance with other gliders and
towplanes that install it, and if you add a mode-S transponder the
jets can see you. It makes perfect sense to separate the "in" and
glider-glider box (not certified) from the much more expensive and
certified "out" and "jet sees you" box. I just can't understand the
fuss. Who is drinking the koolaid here?

I work with the FAA as a contractor, trust me NOTHING is ever simple

Amen. The Navworx "simple solution" transceiver draws nearly 1 amp at
12 volts WITHOUT a display, doesn't integrate with any existing
soaring computers, doesn't do glider flight path projection that is
essential to glider-glider collision avoidance and doesn't directly
receive 1090ES data-out signals for the multitude of areas where
that's what you need because the ground station coverage isn't
designed for the places glider fly. Oh, and it costs $2500 but doesn't
include PCAS. So it solves exactly ZERO of the problems that currently
matter to glider pilots and, IMO, is likely to lose out to 1090ES in
the long run because of the aforementioned regulatory requirements.

PowerFlarm plus a Trig 21 is a great way to go because it solves
actual problems we have today and PowerFlarm alone is a pretty good
improvement overall and adequate if you don't fly near a major
commercial airport. Seems simple enough to me.

I see on average about 6-7 1090ES ADS-B aircraft with a simple rooftop
antenna in Oakland, CA, USA.
Off course, most are international carriers going in and out of SFO.

Which also brings up another source of info on this - so called
"virtual radar", Dave Nadler and I was also talking with me about
offline about this so I thought I'd share. There are relatively low
cost ADS-B 1090ES receivers available that hook up to PCs and vendors
of those products have built closed networks based on those systems
where you can see 1090ES based traffic. Those receivers can get pretty
impressive ranges (up to hundred of miles) with a good rooftop
antenna. The momentum to do all this has been from aviation/technology
hobbyist in Europe where there has been early adoption of 1090ES data-
out by airliners. There is not full 1090ES data-out carriage
requirements in Europe yet and we are many years away from full
carriage in the USA. The network of private 1090ES monitoring
receivers in Europe is pretty impressive but relatively sparse in the
USA.

In additon to these closed networks (where you have to buy one of
their receiver boxes or at least software to join) is there are also
open-network versions of these systems including FlightRadar24 which
has sparse USA coverage. But here is what you can do with it...

o On http://www.flightradar24.com go to "Jump to Area" and select
USA.
o You will see some traffic around Washington state, Los Angeles Basin
and a few other places.
o Click on an aircraft icon to get information about the aircraft and
the carrier.

If you see the flight there it is equipped with 1090ES data-out so
this gives a feel for what airlines, aircraft and flights in the USA
are 1090ES data-out equipped. The coverage is very sparse and it is
not clear what coverage each location actually has and it is not clear
what filtering if any is applied to non-airline flights. The confusing
"Radar" labels like KLAX do *not* mean this is a feed from KLAX tower
radar, SOCAL approach etc. its just what the private owner of the
1090ES receiver called his receiver station.

Here for example are the flights I see right now over the Los Angeles
Basin.

American Airlines B737-823 (B738)
American Airlines Boeing 767-323 (B763)
Delta Airlines unknown
United Airlines Boeing 777-222 (B772)
Virgin America Airbus A319-112 (A319)
Virgin America Airbus A320-214 (A320)

We are just at the start of this. Europe has been leading with heavy
aircraft adoption (look at the Flight Radar 24 maps for Europe) but
with the 2020 ADS-B data-out mandate now the USA is finally starting
to get going. By 2020 all the airliners, private jets, turboprops,
some high performance singles and twins etc. (anybody who flies over
FL180) will be mandated to have 1090ES data-out. And I expect many
other aircraft owners will choose 1090ES data-out to meet the 2020 ADS-
B carriage mandate. I expect some domestic airliners and freight
haulers who see some early ADS-B data-out benefits in the USA will
adopt within their fleet well before 2020, its just hard to find out
exactly their plans. Personally I am very happy that PowerFLARM in the
USA gives us this ADS-B compatibility/future path.

And there is a virtual radar portal at http://radarspotters.eu/ which
links to different products etc. if you are interested in this stuff.

So much for the assertion that ADS-B is far off into the future.
