I've just started flying with a Mode C transponder and have been
alerted a couple of times of approaching traffic when it started replying to frequent interrogations. I was able to locate these aircraft visually. Clearly an alert system would be an inexpensive and valuable asset. Having the right of way in a glider is about as useful as having right of way in a sailboat when you're about to be run over by a mega container ship (which has also happened to me). Large aircraft (and vessels) just might not see you and, even if they do, can't avoid you becasue of their mass and speed. I'd just like to steer clear of conflict, which includes alerting others to my presence and learning about theirs. Good grief, there are still folks in the USA (including some well-known glider FBOs) that fly without radios, let alone transponders. Mike |

Flarm is, Flarm to Flarm. Up to now it is mainly fitted to gliders,
practically universal in the European Alps, and widely fitted in Australia. In the Swiss Alps it is also fitted to rescue helicopters, partly because of its obstacle database. ADS-B out can be read by ADS-B in. In Australia they are working on the idea that an enhancement to ADS-B could enable it to read Flarm, and an enhancement to Flarm could enable it to read ADS-B. This is why things may improve when Mode A/C and Mode S are phased out in favour of ADS-B. In Australia Flarm is built under licence (OzFlarm), there are other licensees. Is there nobody interested in doing this in the USA ? It would surely be ideal for any light aircraft. I understand that there is an add-on to Flarm which can sound a signal in headphones. Remember, Modes A/C and S are only transmitted when the Transponder is triggered by an interrogation. Flarm and ADS-B transmit regularly without having to be triggered. W.J. (Bill) Dean (U.K.).

Hmm, the glider is thermalling - probably the easiest thing in the air
to see from another aircraft approaching. So much for professional pilots looking out the window. If the glider had been cruising I could understand it. I've lost gliders I've been following when I knew where they were. But there is little excuse in a two-crew cockpit to miss something as substantial as an 18 meter glider thermalling in front of you! In the AF we called it clearing your flightpath. Everything else is secondary at jet speeds. Good job getting the jet and it's valuable pax back unharmed. Love the pic of the glider spar in the radome! But I would love to hear the crew admit they were heads-down at the time of the collision, if that is what really happened. Of course, I could be totally wrong - sun, bugs on the canopy, etc... And this assumes the glider was actually turning, of course. Well, it's better than trying to take off on the wrong runway, anyway... Check 6, guys! (and 9, and 3, and 12, and...) Kirk 66 |

A thermalling glider should be able to see approaching aircraft more easily, too. Quite different from being run down by a faster aircraft coming up behind.

reports are the ASG29 had a transponder..
so now what are we going to enforce.. BT "Ramy Yanetz" wrote in message om... A miracle. Did the ASG 29 used a transponder? Assuming not, I am wondering if he could not afford one... This is not good as there are elections going on in NV right now and you know some moron politician is going to try to make the skies safer!! Maybe by enforcing the use of transponders in the Reno area? I don't see a problem with that... Ramy wrote in message ups.com... Rumor control here... Challenger 800X with 5 on board on route to Reno from San Diego collided with an ASG29 around 16,000ft east on Minden on the Pinenut mountains. The Jet landed gear up at Carson City the pilot sustaining minor injuries in the initial impact. The Glider Pilot bailed and landed ok. Look at KRNV.com or RGJ.com for more info. This is not good as there are elections going on in NV right now and you know some moron politician is going to try to make the skies safer!!

Are there any low cost ADS-B units available?

The reality is that it is incredibly difficult to see converging traffic
that is approaching at 200-300 knots.

I don't think it's been confirmed the transponder was operating, but I'm sure ATC knows, and should have the tapes to prove it. -- Change "netto" to "net" to email me directly Eric Greenwell - Washington State, USA www.motorglider.org - Download "A Guide to Self-launching Sailplane Operation" |

Is that an appropriate and prudent speed to fly in an area know for soaring?
