IDAHO FATALITY
Talk of getting kicks......I enjoy watching others do low passes as
much as doing them myself. Better if they are open class ships. I don't know....something about long legs and big ...ah ....well lets move on. The idea that the guy flying is having a great fantastic rip-snorting time cashing in all his altitude letting his glider take him on a magic carpet ride for a few seconds is simply a joy to watch. You get to see his airmanship at work.....simply applying what he knows with confidence to the art of flying. Hey...I don't think I've ever seen a girl do a pass. Now that would be a thrill.....perhaps in a Nimbus. A tall girl, in a Nimbus doing a worm burner and... she wears glasses. What kind of beer???hmmm... Learn to enjoy the ride boys, the asteroid is only getting closer. R |

IDAHO FATALITY
It was noted...
Hmm, we recently had a lot of talk about practicing rope breaks, down to 200' or so, with opinions that any self respecting pilot should have no problem with a rope break at 200-300ft. Gee, I have no problem getting higher than that on a well planned and executed low pass, in everything from an ASK-21 and G-103 to an LS4 or LS6. So some of you guys are OK springing a sudden low altitude pattern on a guy in training, but tell others that they shouldn't do low passes at any time because they are "dangerous"? You guys are hypocrites. Ummmm...what're the chances of having an unplanned, low-altitude rope break/premature termination of tow (for any reason) vs. having an unplanned zoomie suddenly appear? Why is one mandated to be practiced (with instructors) and the other not? Might not the answers to the preceding two question be fundamentally related? Careful reading of my previous posts won't reveal me *telling* others they shouldn't do zoomies; trying to *convince* them not to is quite a different thing where I come from. Webster's New Universal Unabridged Dictionary defines hypocrite as: "one who feigns to be what he is not; especially one who pretends to be pious, virtuous, etc. without really being so." As I noted in another thread about zoomies: BTDT; stopped doing them ~1980; have seen (and enjoyed watching) many since (while simultaneously mentally cringing and hoping/praying nothing bad happens); wouldn't consider my future significantly poorer if I never see another one; sincerely hope I don't personally know (even via RAS) anyone who may be a part of a zoomie gone bad in the future. We soar because it's "fun". Nobody forces us to do it. For some, the fun is in hanging around the airport in a 1-26 or 2-33, never out of gliding range. Some enjoy bashing along the ridges in freezing weather. Some like to see how high the wave will take them. Some like to race against others, flying in marginal weather over marginal terrain to see who is best. Some like pulling Gs. None of it is necessary - we do it because we ENJOY doing it! I enjoy pulling off a safe (yes, safe) low pass. I avoid getting into a position where I intentionally try an unsafe low pass. The same can be said about any other maneuver we do in gliders. And I don't do it for you ******s on the ground who don't like them. I do it for me, and my friends who enjoy the beauty of a skillfully flown maneuver. And you aint lived till you do a double formation low pass over an FAA examiner... He was cool about it! Good for him and good for you, and may all your future zoomies continue to be trouble-free. Respectfully, Bob W. |

Then, things get a little tight in the pattern, like he's too close and too low. His attention gets focused elsewhere and stress goes up, and next thing you know the yaw string is right over to the side on base to final and he wants to pull the stick back. That's another one which I've asked about here before, but no one has ever answered. Around here we have ridges and students are very likely to have quite a bit of practice at doing well-banked coordinated turns while a lot closer to the ground than normal base-to-final turns, in the presence of considerable wind drift, groundspeed higher than airspeed (approaching the ridge from upwind) etc. Is there correlation between screwed-up base to final turns and flatland fliers? Quite possibly. *Mountain pilots know they can't trust the horizon so they learn to control pitch attitude with airspeed and bank with rate of turn. *Mountain flying requires a bit of instrument skills. Hmm. I don't think that's true, at least for me. You don't need an actual horizon, all you need is something far enough away that if it moves in the canopy it's because the aircraft attitude changed. It doesn't even have to be straight ahead -- well out to the side is fine. Even with a true horizon available, you're only using the horizon for short term attitude stability and cross-referencing it to something else (wind noise, control feel, airspeed indicator) to calibrate what attitude you should be holding. I've had the very interesting experience of flying with a friend doing overnight freight runs in small turboprops (e.g. Cessna Caravan). When you're ostensibly flying on instruments and using the artificial horizon for attitude control, it's quite astounding how much difference there is between having even two or three external points of light from stars or farmhouses and not having them. When you're deep in IMC in the middle of nowhere you are working very very hard. When you have even the slightest external references that you may not even be consciously aware of it gets 10x easier. Your theory sounds more appropriate for people flying in severe haze or cloud. |

The very fact that zoomies are planned in advance makes them less surprising, and therefore less prone to panic, rushing things etc than unplanned rope breaks. Why is one mandated to be practiced (with instructors) and the other not? You have several times now ignored the possibility of training how to do a low pass with an instructor on board, just like any other gliding maneuver. |

Nor - I've little doubt - do most interested readers of the NTSB database. My working conclusion is, historically the vast majority of NTSB glider investigations state the obvious, while lacking any ability to place the obvious into any sensible context. Donning my Great Karnak hat, this fatality's Probable Cause will likely read: Failure to maintain airspeed and control for unknown reasons. And at that, my supposition may well err on the wide of 'too much context'...time will tell. However, savvy NTSB-database-reading glider pilots can still make their own inferential, context-based conclusions from NTSB data. In fact, they *should* do so, if they're interested in maximizing their chances of not eventually becoming a read-about incident or accident in the database. Bob W. Precisely, and this is why we should encourage speculation rather than 'wait for the NTSB report'. And I'll start by saying that from a second hand report this was a spin of the top of a (not so) high speed pass. I for one will think twice before attempting a high speed low pass again especially if i am not 100% sure I'll be able to build enough speed. This had been another terrible year for glider accidents and it is tragic to loose so many but we should all try to learn as much as possible from every accident to increase our safety. Ramy Without attribution to anyone, I've gathered the following. The PIC was familiar with the site, having flown rides there last year with a 2-32 (the one in the earlier MT fatal crash). He owned the BG-12b since 2007. However, this was apparently his first outing with the glider and his fifth flight in it. He'd flown it earlier in the week. Stall tests showed a tendency for right wing to break first. The downwind was apparently described as slow (and low) despite an estimated 10-15mph tail wind. If that's ground wind, it's likely to be somewhat higher at 100ft, 200ft, and 300ft above the ground. Turning 180 for a landing in a wind gradient reverses the wind speed differential between the lower and higher wings and maybe allowed the lowered wing to stall. Some may recall the Derek Piggott story of doing a 180 to a down wind landing being the only thing that allowed enough aileron authority in the wind gradient to be able to level the wings for landing.

Thanks for helping make my point more clear. The planned aspect to zoomies is all the more reason not to bugger one up...yet it would seem possible that this *might* have been the case here.

Uhh...of *course* it's a (theoretical only?) possibility. Are their sites in NZ where folks could travel to do this? I'm unaware of any in the U.S. that advertise zoomie instruction is part of their standard offerings. Regards, Bob W. |

Thrilling enough to watch in itself, but made especially so as he continues the push-over until you think he is going to do it again. Radio contact is maintained with all local traffic, power and sailplanes. In UK high speed low finishes were banned after a photographer on the airfield boundary was killed, but prior to this they were commonplace. It was not unusual to see six gliders in various stages of pull-up, all talking to each other on the radio, and then flying a full normal circuit to land. I don't recall any spin accidents in these scenarios - is this because European pilots are better trained ? |

Come to think of it, we did an 80 kt low pass over the Mynd in a DG 505 on my checkout flight for that site back in April. The instructor was flying and demonstrating a low level way back to the site from the south ridge. We were running fast because we didn't intend to stop and low because that's where I'd be if I needed to use that way back onto the field. Of course, there was no pull-up needed because the Mynd is a ridge- top site, so we just swung left and out over the working ridge.... If you want to try find out about flying there and the techniques they use, I'm certain the Midland gliding club would be delighted to have you visit them. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |
