PowerFlarm offers new Version, PowerFlarm Fusion Includes Many newstandard Features!

To the best of my knowledge it now works - but I don't actually know whether it does.


Take a recent Flarm flight log and upload it to the Flarm analyzer. It will show you the results for the A and the B antenna...

I normally use igc files from my LX9000 which don't work with that tool. The LX range analyser does not give me the individual antenna information. I just tried a file from my PF which did have readings from the two antennae - good news. Less good was that one seemed to have very poor range - I don't know which antenna that was. However, the CARP file analyser (Continuous Analyzer of Radio Performance - new to me, apparently accumulates range data from multiple flights) did not appear to find any data, and I had to use the 'Classic Analyser' although my firmware version was 6.82 and the website said CARP should work from 6.80 - so I was only seeing data from one flight, whereas what I got from the LX9000 appeared to be from multiple flights and just showed decent all round reception (minimum of 10k all round).

Mark, for at least the last 2-3 years my club's inspectors have verbally
checked when I'd last updated the FLARM firmware, but at my glider's most
recent annual (March 2020) I noticed it is now on the checklist.

"I think my experience would apply to almost any Schleicher glider - they all use essentially
the same fuselage, starting with the ASW24, which do not have carbon in the nose."

The fuselage mold may be the same, but the layup in newer gliders is carbon fiber.

I found a major improvement in range when I moved from a single antenna over the glareshield to dual antennas on the canopy sides of my ASW-27.

I did Range Analysis on six installations and documented the results in the 2019 Free Flight. Look for Antenna Placement:

That looks to me like you can buy a license to activate the "B"
antenna. Â*Â*Isn't that like buying a license to active the passenger
side seat belt in a car?Â* Or the rear brakes?


Maybe if you pay extra they'll sell you the feature where it keeps on
working after the firmware "expires"?Â* (As long as the data packets
are still compatible.)

Dan: We have no choice about seat belts and brakes, which are mandated
by law. Do you want to go there with PowerFlarm? :^(

Dan: Buying a license for an optional feature (also known as "buying an
optional feature") is like buying the "primo" optional interior for your
new car, except you can do it anytime, even years after the purchase,
unlike that fancy interior. Would you rather they included everything
that is now optional, and charged you for it, instead letting you pay
for only what you need?


I also agree with Dan that having to buy a license to activate the "B"
antenna is ridiculous. Yes it's an optional feature, but it shouldn't
be. They've already developed this feature and it's built into the
device. And it is important for the safety benefit. That's different
from some of the other optional features like IGC-certified logging,
which are separate from the collision avoidance purpose, and they can
make those who want that feature pay extra while keeping the price lower
(?) for the rest.

The B antenna is not required for safety in my glider. My ASH26E has two antennas in the nose
(Flarm and ADSB), producing excellent range in most directions, and sufficient range to the
rear for collision avoidance. I tried a B antenna on the belly, and it did improve the range at
which I could detect other Flarm units, especially below. Since the unit already had sufficient
range in all directions, the B antenna did not improve it's collision avoidance ability, and I
removed it after 10 or so flights.

I think my experience would apply to almost any Schleicher glider - they all use essentially
the same fuselage, starting with the ASW24, which do not have carbon in the nose. That's a lot
of gliders.

Eric, you wish what you wrote to be a fact, but in reality you can not have 100% in a glider that uses carbon and has only one antenna. I used to own ASH-26E with Flarm and from experience know there are blind spots. One flight in a competition gaggle would prove it for you. You will not be seen by others all the time and you will not see others all the time on your Flarm if you and they have only 1 antenna.

The gaggles I've flown in did not expose those problems, perhaps because they have not been as
dense as the worst contest gaggles sometimes are. Did your 26E have the antennas mounted in the
nose? Where was the worst blind spot?

In general, I would expect the signal strength from nearby gliders (+/- 500'vertically, 1000'
horizontally) in a gaggle to overwhelm all but the very worst antenna placement.

Good point. Receivers can be very sensitive. Years ago GPS receivers
were finicky, had to put them outdoors for 15 minutes to get a fix, etc.
Nowadays those in recent model cellphones work just fine on the
passenger seat of a metal-body car. Note that the GPS satellites are
generally low on the horizon. And very far away. Presumably the
signals come in through windows and bounce around inside the car. No
idea if the FLARM receivers are comparably sensitive. Nor whether
carbon fiber reflects radio waves as well as sheet metal does.

My antenna was mounted in the nose and the worst coverage was to the back, above the glider, very dangerous blind spot. I then moved the antenna to the glare shield, improved the above the glider and worsened below the glider.. Blind spot below the glider was more acceptable to me.
