Dear All, As part of my research into lookout and mid air collisions it turned out that in Europe, where most of the worlds gliders are located, the incidence of low level spins has drastically reduced. This was accounted for by the improvements in glider design. Modern gliders from about LS4s on are far more resistant to spinning compared with IS 29s, early Cirruses and some even worse older designs.
Despite good training pilots will sooner or later get themselves into unfavourable situations where they are at risk and then it is preferable that they are in a spin resistant glider. There are limits as to the worth of spin training. I originally instructed at a winch launch club where once a year a tug was brought in and spin training was conducted from 3,000 ft. Everyone was quite happy employing standard recovery techniques. Later I instructed at a winch launch club where aero tow was not available and sometimes conditions were not favourable for extended periods to gain height, so after practice myself, started spin training from the top of the launch using Blaniks, 1 turn only and recovery by 1,000 ft. Despite very careful briefing shortly before, the pilots response was quite different. As soon as they saw the ground directly under them they would pull the control column fully back and for good measure in the direction away from the downgoing wing. What chance would they have had if the height was 500 ft., were in a vulnerable glider, stressed, surprised and not in current spin training practice? A snow flake would have a better chance in hell. Sorry about the instructors who get their jollies spin training but we should be banning or advising against the importation of Puckatzs. They have an appalling record for spinning in. How much nicer to send our early pilots off in ASK 21s and those from the Grob family that are comparatively forgiving, Harry Medlicott ----- Original Message ----- From: "Derek Ruddock" <[EMAIL PROTECTED]> To: "Discussion of issues relating to Soaring in Australia." <[EMAIL PROTECTED]> Sent: Tuesday, September 21, 2004 12:16 PM Subject: RE: [Aus-soaring] Reasons NOT to spin for fun > One thing you can say in the 28's favour is that 24 people have NOT been killed spinning it. > Unlike the Pooch... > > > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Catherine Conway > Sent: Tuesday, 21 September 2004 11:58 AM > To: 'Discussion of issues relating to Soaring in Australia.' > Subject: RE: [Aus-soaring] Reasons NOT to spin for fun > > Sounds more like a reason NOT to buy IS28's :P > > (ducks for cover) > > -Cath > > > > > -----Original Message----- > > From: [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED] On Behalf > > Of Jason Armistead > > Sent: Tuesday, 21 September 2004 11:01 AM > > To: Discussion of issues relating to Soaring in Australia. > > Subject: RE: [Aus-soaring] Reasons NOT to spin for fun > > > > > > > > One reason not to spin "for the hell of it" is that in some > > metal aircraft, > > e.g. IS-28s, such "aerobatic" maneouvres actually reduce the > > airframe service > > life.
