View Full Version : Flarm Net

Can anyone tell me if Flarm Net information is displayed on a Power 
Flarm portable directly?  Reading the PF Portable manual implies that 
the ID information is displayed only on external devices, i.e., 
Butterfly, Flarm View, etc.  I can't find any information that directly 
states that the PF portable will display the information.

Yes, I believe it is.  It's been 3 years since I have used mine. It I do believe tail numbers can be programmed manually or automated with the addition of the FlarmNet file.

Maybe I have answered my own question:  According to the Flarm Net 
website the PowerFlarm is not listed as a supported device, but XCSoar 
is listed.  My Streak/XCSoar unit is interfaced with the PF portable and 
my CNvXC vario.  The Flarm logo is now displayed at the bottom of my 
moving map so I suppose that if I ever come within range of another 
Flarm equipped aircraft, I'll see it on my moving map.
Hey Renny, next time we're both at the airport, let's see if I can see 
you on my display across the taxiway.

From my limited experience of FLARM that won't work because FLARM filters out stationary targets.
You can however have Renny flying nearby and spot it from your unit on the ground.

My experience is that you will see PowerFlarm targets on your display on the ground even if not moving, but you will not get Powerflarm collision warnings.
In a contest grid you will see gliders none of which are moving.
I also tested this with a close 3' drive by Powerflarm in auto and PowerFlarm in glider in parking place.  Again Display showed target but no collision warning.

The portable does not display contest IDs from a Flarmnet file. Would be nice if it did.

The XCSoar manual says that XCSoar will display targets and their IDs.  
I've just downloaded the file for my XCSoar device and will install it 
next time I go to the airport.  I'll have to wait for the weekend to 
find another user to see if it works.
I did finally get a Flarm alert yesterday as well as a PCAS alert from 
the same aircraft.  That really clutters the screen.  The other guy had 
the same experience - Flarm and PCAS from me.  We're trying to figure 
out how to prevent that.  Anybody got any information on that?

My Portable does, and I can select a target, click the button, and see 
the info. The manual tells you how to do it: page 38 on the ver. 3.41 
manual.

Eric,
I just reviewed the manual/page you referenced and it looks to me like 
the FlarmNet info is presented on the Butterfly display rather than the 
PowerFlarm Portable display.  Can you confirm one more time that you see 
FlarmNet info, e.g., call sign on the Portable's built-in display or is 
it on a connected display?
Thanks,
Dan

I suspect Eric refers to Flarm ID, not contest ID. Or is referring to external display. Otherwise I am also puzzled how he manage to get flarmnet data into a powerflarm portable.

Thanks.  I just got back from the airport (no flying today) and Renny 
and I cranked up our portables, mine in my glider in the hangar and 
Renny took his out of his glider and drove it around in his car.  In all 
cases I saw only the arrow on the PF portable display and I saw his ID 
on my Streak (XCSoar) Flarm Radar display. Can't wait to try it in flight.

It's my understanding the display in the portable is a Butterfly 
display, just like the one that comes with the Core, and that it's 
updated the same way. I don't recall my portable in the Phoenix 
operating any differently in flight than the Core in my other glider.
My portable is at the airport, so I can't check directly for a few days.

No, it is not. That is completely wrong.
The portable display uses its own distinct display code,
running on a single processor with FLARM main processing.

So you know that Flarmnet doesn't work on the portable?

Well, it worked this way:
1.  It belonged to George Applebay and had never been used, though Renny 
kept the firmware up to date.
2.  It was priced at less than 50% of retail.
3.  In several flights, I've had only one Flarm contact and I had him 
visually first.
4.  I was already familiar with PCAS.  But I think the PCAS display on 
the PF portable can be misleading unless you understand how PCAS works.  
One might be tempted to think that the target is at 3 o'clock rather 
than anywhere around the circle drawn on the display.
5.  I like receiving ADS-B targets though, for the most part, they're 
displayed at +99.  Still I think I've seen one that was only about +27 
and that, added to my altitude told me that he was VFR and eastbound.  
Or maybe that was a PCAS target.
6.  I have Flarm targets displayed on my Streak/XCSoar.  I just made 
that happen during ground testing.  I don't see anything in the manuals 
to indicate that I'll see PCAS targets though that would be nice, too.
7.  I've joined FlarmNet.
8.  It'll probably be the spring before it gets any real use.
9.  Since I've had only 1 Flarm contact, I submitted that igc file to 
the performance analysis tool and it looked pretty good for over 300 
deg.  Kinda weak at 6 o'clock, though.  I'll wait until I have better 
data before cutting my antenna cables to length.
Thanks for the welcome.

My data set is small but my immediate opinion, based upon about 20 
minutes of driving a car carrying a portable around the airport, is that 
it doesn't display FlarmNet information on the portable's built-in 
display.  My portable's display showed the expected arrow head symbol 
only.  My Streak/XCSoar showed the symbol and "3R" which is Renny's call 
sign.  I could also see the 6-hex-character identifiers of the airliners 
overhead.

Portable PowerFLARM displays *NO* identification info for targets.
Neither does PowerFLARM Core use FLARMnet.
FLARMnet info is used by display devices to map FLARM ID into other identification info.
FLARM provides BFN/BFW support for update of downstream Butterfly products.
For example, I can update the software and/or FLARMnet info in my
Butterfly displays by placing these files on a USB stick, plugging
into Core, and then powering on whilst holding down button on Butterfly.

Dan,
It took me a long time to realize that the PowerFLARM Core and the Butterfly Display are two SEPARATE computers that happen to talk to each other.  The Butterfly display is the computer that takes the FLARMnet data and attaches it to the signals the Core sends to it.  I kept trying to think of the display as a dumb screen for the core & that got in the way of understanding how to deal with them.
Dave's stated pretty categorically that the Portable doesn't attach FLARMnet data and if anyone would know, it's Dave.  That seem logical since it's missing the additional processing provided by a butterfly display (computer)..
Glad to hear you've joined the FLARM tribe.
Cheers,
Craig

Thanks Craig,
I've got it all working.  The PF portable is on top of the glare shield 
and my Streak running XCSoar is on a stalk below the EFIS. The Streak 
displays Flarm targets on the moving map as well as a Flarm radar 
display which also displays FlarmNet ID.  As soon as I get comfortable 
with the Flarm stuff on the Streak, I'll move the portable to the right 
side so my wife will have a display as well. Two sets of eyes are always 
better than one.
