You just proved the point about why people should have spin training :
-Your impression is not correct. -You haven't had enough spin training, you still don't get what's important about it. You will once you get enough spin training and read some of the material.

Hi All
Hope I'm not covering old ground on this thread and may I start by saying since we don't know the cause of the recent Puchacz incident, this doesn't relate to it, but the content of the thread. I knew John. He smiled lots. Much good advice within indeed. My first syndicate was a Bocian and IS29D, both of which spun at will, the IS29 without any pre-stall buffet. I once managed to spin the IS29 at the top of a loop which was slightly the wrong side of exciting... It does seem inexplicable (try as we might) that competent folks on well proven gliders get bitten. Sure spinning is complex and instruction invariably tries to be simple - 'if the nose drops, ease the stick forward' etc. With brain overload easily induced in students, it has to be simple. Perhaps the more complex subtleties of spinning SHOULD be introduced later as 'Advanced spin awareness'? One other consideration you may wish to ponder is the British weather, with possible icing and wet wings. This easily produces an asymetric wing: Imagine the instructional flight. All upper air work done well, the air's smooth and we try that old chestnut of the 'unexpected' deeper stall in the circuit - the one where the nose is down, grounds coming up and we just can't resist pulling before it's 'unstuck'. Demonstrated to me. Instructed by me. But NEVER in a wet or icy Puchacz, Bocian, IS29. Even a gentle simple, stall could bite very differently with wet / icy wings and turn a benign glider into something far more interesting. Fly safe out there.

No - I reckon all instructors should have the skills to recover from any spin they end up in, and all instructors should be competent and happy teaching basic spinning. Can you imagine a club in which only the more experienced instructors were allowed to teach winch launch failures? (And, by the way, I have had a senior instructor at a Very Large UK Club explain to me that they always rotated straight into the full climb on the winch because "we've got a modern winch and we change the cables regularly - we don't have cable breaks " : It was far better to give the first spin experience to a : student as the base to final overruddered break and : recovery.

I don't : think you can. In one way it's glibly easy. They died. And unless that was because of an unforeseeable mechanical or structural failure of the aircraft, or because some unexpected turbulence through the glider into a strange and unrecoverable spin mode, then it was their fault, just as the overwhelming majority of gliding accidents are the pilot's fault. I really don't like being this blunt but, since you ask, the ones who are alive are better pilots. : It should be checked, in theory, but I do a bit extra when : I'm going to fly inverted, or some other unusual maneuver. : I've noticed that "full" rudder on the ground may be only : achieved at the maximum leg extension, combined with maximum : foot extension I'm fortunate (for once) in being 6'4" then - hgetting full pedal travel is - cough - not an issue. : Emphasis on : seating position and rudder adjustment so that each pilot : can apply a high level of force tot he rudder at full throw : might be just sufficient to alleviate some of these training : deaths.

But I think we should look at every part of them: what makes me unhappy is a regime which works fine in nice docile two-setaer trainers, but then doesn't apply to single seaters. Every presolo K13 pilot in the UK checks "undercarriage" and "flaps" going downwind ... Ian |

The difference is that you HAVE to land. Should simulated cable breaks be taught, or should pupils just be taught to recognize the symptoms of a cable break and be taken up in a special glider a couple of times as they near first solo to practice. I've never had a real cable break, myself, so I know it's not going to happen to me ... Ian |

The good two seaters are in private hands and not available and some of them are placarded against deliberate spins. That leaves you with club heaps subject to unknown history , amateur maintenance and unknown numbers of 20 cent pieces under the seats amonst the control system. The instructors all have their GFA ratings. The system does nothing to weed out the incompetent even when they demonstrate their incompetence. We had one instructor 3 years ago spin a Puch in from low altitude while thermalling with a student because the instructor got out of glide range of the airfield and wishing to avoid derigging (the tug was a hired one not to be used for field retrieves) took over and tried to thermal away. Two serious injuries. They must be one of the few Puch spin ins where both survived. The instructor had been the Chief Flying Instructor of that Club in recent history. : And they won't spin down on you from above. If that blithe confidence is misplaced, though, will they be able to stop spinning? The "blithe confidence" is based on thousands of hours where this hasn't happened. Unlike the blithe confidence displayed by some that they will always manage to recover from spinning Puchaczs despite the growing evidence to the contrary. Though it's not really the reluctance about spinning which gets me - it's the general nervousness about flyng skills which it reveals. If you aren't a little nervous before takeoff maybe you don't really understand the problem. You are less than 60 seconds away from perhaps having to demonstrate that you are mentally prepared and skilled enough to cope with a low altitude emergency. I don't know about you but this always gets my attention. : Some of the attitudes revealed in this thread make me despair that : anything will ever happen to improve the soaring safety record. I agree with you there. Ian I really don't care whether you or Arnold Pieper or anyone else spin Puch's or not as long as nobody is coerced into doing so. There is a perfectly defensible position that says repeated full spin demonstrations are unnecessary. We aren't going to improve flight safety by continuing the "tick the box" mentality that annual checks encourage. The BGA and GFA records speak for themselves. Mike Borgelt |

Personally, I think the tail ends of single seaters sticking out of fields and hill sides makes a pretty good attack on that position. Ian |
