No I do not represent Flarm, Trig, Becker, NavWorx, or any other company whose product you'll see me talk about in detail on r.a.s. But I care passionately that people understand technology related to collision avoidance. Transponders, Flarm, ADS-B, glider batteries, etc. There is all too much confusion about this stuff. I've been flying where we have had some mid-air collisions in the area and other incidents and lost too many people I know to mid-air collisions. This goes back to the day I was flying out of Minden when the Hawker and ASG-29 collided. And all the subsequent confusion and misinformation I saw on transponders, glider batteries, ATC radar, TCAS etc. so I've worked to especially try to educate pilots in Northern California and Nevada on those topics. I'm voluntarily helping the folks who are putting together the USA web site for PowerFLARM, esp. reviewing technical content on collision avoidance systems. And I do give (free) feedback and suggestions to Flarm folks at times on things, just as I do to Trig and others. e.g. You'll see features in future Trig releases that I've pushed for. I've also worked to educate some GA industry authors on technology issues and in discussions with both pilot organizations and some avionics manufacturers about how ADS-B things will or will not work easily for pilots to use. In the weeds stuff but things I want to see the manufacturers think of and want to see reviewers start looking for as they discuss technology and review products. And some of that is starting to slowly appear e.g. see Max Trescott in a recent EAA Sports Aviation Magazine nicely clarifyied an ADS-B transmitter is required for TIS-B to be received by a UAT receiver - the first time I've even seen something as simple and important as that mentioned in any popular coverage of ADS-B (thanks Max). I'm pulling together content for our annual PASCO safety seminar where I'll be talking about collision avoidance technology so I want to know what things people find confusing or want information on. And Urs Rothacher CEO of Flarm is speaking at that seminar on the history of Flarm development. Should be interesting, well his bit at least. So seriously what else is not clear? (BTW I just found one myself, people need the power output specs for powering an external PDA etc. to see if it can power their PDA/PNA. Also the actual power specs of the device are still not public AFAIK). Thanks Darryl |

Flarm has been mandatory in Australia for at least the last 3 years in
National and regional comps. There has been no mid-airs in comps in that time. There were on average probably one ore a little more mid-airs a year before that. It won't stop them all, I nearly got cleaned up by an inexperienced Pilot this year but at least I knew he was there and I took avoiding action. The last WGC in Hungary had about 70% Flarm, I reckon the guys without it [on purpose for "tactical" reasons] were idiots!! Initially the units were $500, now still under $1000 and can be linked to maps etc. Towplanes have them too! You guys in the US really should get on board! Whatever frequency your government will allow should be able to be programmed in both Euroflarm and Ozflarm. I am seriously considering if I will fly in Uvalde or any further WGC without mandatory Flarm. Tom Claffey |

Tom Claffey The issue in the USA has really not been willingness to adopt Flarm Technology amongst pilots. Flarm has not had product available for sale in the USA. Likely for multiple reasons, including concern about liability and the need for FCC approval which is a bit tougher than many other countries. The choice of the actual frequncy to be used has been done for years (and your Flarm units will probalby tune to that frequncy if you brought them here). The first chance for USA pilots to adopt this technology will be the upcoming PowerFLARM product. I am not surprised at all to see Australia leading with technology adoption(*), but the situation in the USA is a bit more complex with more issues than airliner and GA traffic issues. That maybe makes the PowerFLARM with 1090ES data-in/PCAS maybe even more interesting here, but at a higher price than the older Flarm units. Darryl (* I am an Australian). |

If Existing FLARM supports the freq to be allocated in US why are not manufacturers of those units jumping on the US market and getting FCC certification. I know what freqs are supported by FLARM as I have the documentation. What freq is being used for USA and where is that published? Why are we waiting for PowerFLAM with it's still undocumented new features when FLARM products already exist? On the other hand, if Power FLARM is being built with an RF section that is unique to USA then potential purchasers may want to know that. It could limit both resale value and its usefulness for US pilots that fly overseas. So why is US PowerFLARM not identical with PowerFLARM being marketed to the rest of the world and are the systems interoperable? Andy |

Eric, as I posted earlier, on another thread, here in the UK I have
avoided the EASA paperwork problems by using a basic Flarm, held by hook and loop tape on top of the instrument coaming, run from a dedicated battery separate from the main glider instrument supply and carried behind the seat, all of which I carry on to the glider as personal equipment. The same battery drives the smallest PCAS unit, fastened similarly and also personal carry on equipment. Total cost of the two when I bought them was about £1000. If you want to see a picture of my glider with its Flarm, PCAS, and other bolt on goodies on the instrument panel, see : http://picasaweb.google.com/cnich150...78413677251106 .. Chris N |

I have to wonder if making US Power FLARM somehow different from PowerFLARM sold to the rest of the world, and having a separate a US website, is perhaps an attempt to legally separate the two PowerFLARM variants. I don't see how that would work though if the manufacturing company was the same and the alerting algorithms are common to all FLARM products. I've been subscribed to the PowerFLARM newsletter since Feb 2010 and have not seen any information there, or on the PowerFLARM website, that suggests a different product will be sold in USA. Andy |

I don't see how that would work though if the manufacturing company was the same and the alerting algorithms are common to all FLARM products. You know there are often simple answers to simple questions without getting into all these complex worries. The web content for the USA is simply being coordinated by the USA distributor and others who want to see appropriate USA technical content available. See other comments below why this is needed. I've been subscribed to the PowerFLARM newsletter since Feb 2010 and have not seen any information there, or on the PowerFLARM website, that suggests a different product will be sold in USA. Yes it would be great to have more information on newsletters etc. I don't know why that is not happening, besides the team just being buried with work. I think most people are trusting that guys who have delivered Flarm in the past with huge success know what they are doing. I've tried point out before, but will do so again, is that the reason there needs to be a USA web site is the market is different and there are some product differences. The market differs in ADS-B adoption/ mandates here and how ADS-B will work. Key USA issues/features like ADS-R and TIS-B make no sense to have on a European web site but very important to talk about on a USA web site. And because of differences in ADS-B (and even transponders) what is said for one market can be confusing or just plain wrong in another. The product difference I have worried about are as simple as ButterFly is offering different levels of flight recorder as standard in different markets, that has already caused confusion here. That's why the flight recorder was not mentioned on the European site and is mentioned on the Craggy Aero site (-- I know Richard is actively working to make sure all the info on his site is up to data and correct for the USA market) and also needs to be on a USA product web site.

What freq is being used for USA and where is that published? We've been over the frequency here, I've said 915 MHz, there was some innocent confusion from others and Urs from Flarm confirmed its 915MHz. Its on the 915 MHz ISM band using spread spectrum communications. This has actually been known in the Flarm community for a long time. Discussed on Flarm forums and it is mentioned in some Flarm documentation (but not all versions of all docs - no I don't know why). Why are we waiting for PowerFLAM with it's still undocumented new features when FLARM products already exist? Because there are no FCC approved Flarm products from any vendor that can legally be sold in the USA. Flarm is busting their ass to get the new generation RF unit in PowerFLARM FCC approved, its non-trivial work. As in previous products the RF unit is Flarm's technology and they are buried in work getting the certification done. I doubt they would be able to stop work on a new generation product right now and go help others certify existing products. Flarm is not a multinational company with unlimited resources, they are a small group of pretty clever engineers. On the other hand, if Power FLARM is being built with an RF section that is unique to USA then potential purchasers may want to know that. It could limit both resale value and its usefulness for US pilots that fly overseas. I know enough to say that the RF unit on the PowerFLARM is definitively not "unique to the USA". PowerFLARM units brought here and brought overseas will work in any location. So why is US PowerFLARM not identical with PowerFLARM being marketed to the rest of the world and are the systems interoperable? Andy The USA is different from the rest of the world. Starting with we have no Flarm installed base here and we have ADS-B data-out rolling out here that touches a large number of aircraft unlike anywhere else. That combination is unique. And I suspect that is largely driving Flarm to enter the USA market with a combined ADS-B receiver/Flarm product. With how complex things are already with ADS-B I am actually glad they are doing that. Darryl |
