Just pull the little red handle!
I have felt for some time now that my back-pack parachute provides
little more than a false sense of security..............I don't think I would ever get out of a spinning, tumbling ship. The BRS has been demonstrated to work as low as 260 feet during the FAA certification of the Cirrus. This could save you from a mid-air in the pattern or that all time biggest killer. stall/spin turning final. BRS also provides a way out of structural failures or pilot incapacitation. How about stuck low on the wrong side of the ridge with nothing but trees in all directions? The BRS descent rate is about like a normal parachute (like stepping off a 7' ledge). The Genesis installation calls for a 4-point bridle that attaches to all 4 lift fittings, this will result in a wings- level, slight nose down attitude under the chuts. Lowering the gear will absorb some of the landing forces. Flarm is great and I'd buy it in heartbeat if everybody had it. Lets not forget that 2 of the 4 mid-airs in the US last year involved a tow plane and some of them still don't even have radios, let alone transpponders, Pcas or Flarm. Bottom line is; We are all the chairman of our own safety committee and we must take the actions we believe to be the best course to keep us out of harms way. For me that includes installing a BRS. Cheers, JJ |

This could save you from a mid-air in the pattern or that all time biggest killer. stall/spin turning final. Are you sure? Does anybody know at what height most spin-ins from a base/final happen? My concern there is the glider is already pretty low, especially if trying to stretch their glider/hold off the turn. And the pilot is already likely far behind the aircraft and so may be some delay in pulling the handle. I'm not disputing the benefits of a BRS in other situations (including collisions in the pattern) I'm just not sure they would necessarily be that useful in the classic over rudder/under piloting stall/spin off a turn from base to final. [snip] Cheers, JJ I am hoping you buy a PowerFLARM as well as this BRS chute. Darryl |

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). |

"Ramy" wrote I concur. The most difficult and time consuming part is the egress from the glider, not the release of the straps. It is unlikely to be able to bailout from a glider below 1000 feet. A BRS could be deployed instantly even from 100 feet. Ramy ************ I wonder if you could have the red handle attached to an emergency release pin on the gliders canopy, as in bubble clear thing over the top of the cockpit. There could then be a line going from the bubble, to a release for the seat safety harness, and the top of the parachute. Jettisoning the bubble would carry the chute out in the slipstream to inflate, which would then lift the pilot from the plane. An idea, or just a poor idea? Sort of a poor man's ejection seat? -- Jim in NC |

As a relative newbie to the world of gliding, I have in my some 100 flight had two close calls. I consider myself a heads up kind of guy and try hard to keep my head on a swivel, my eyes wide open and paying attention. I have asked a few local pilots why it seems that the preferred color for gliders appears to be white. I understand that the sun might degrade a more brightly painted ship faster than a base white one. Is this really true? It would seem to me that the cheapest form of avoidance would be making ourselves more visible. I am in the market for an older, aluminum ship and would consider painting it bright red if it would increase my visibility. I understand that FLARM only works if the other guy has one. I guess for the time being I will have to depend on my parachute and luck for survival, along with a healthy dose of paying attention. Walt |
