Re: [Aus-soaring] Fwd: FW: Safety Cushions
I have used both Blue and Green both 1inch thick and the test is can you smash your fist into a brick wall at full power without damage. Guess on a 40deg day blue may fail test but passes at all other temps. Once you see the test you will buy confor foam Ian McPhee On 12 October 2012 15:37, Roger Harrop roger_har...@me.com wrote: Ian, We are about to experiment with some confor layer combinations in our ASK21 trainers. Can you suggest a quality brand and/or model of Foam cutter/shaper that we might add to the GCV's workshop for all to use, as hopefully the practice spreads across members.

People who saw the crash may remember after crash he just got out of glider and walked around and I love his statement. Kiwis must have confor in their gliders while the Poms highly recommend it and most club gliders have it. I personally believe it should be mandatory in Australian gliders and just maybe one person who is now in a wheel chair and was sitting on crap makers yellow foam cushions may be walking today. For those that know confor foam give the demo of slamming your fist into 3cm of confor on a brick wall to your friends. As many who know me know I will never sign out a form 2 unless it has confor foam cushion. (nor will I sign out a crap hard to read Altimeter or an undercart without decent green -down and red -up) Lets hope there are a few more AUS gliders using confor cushions this season ou from a wheelchair. Treat cost of confor foam as a one off insurance policy which may save you from a wheelchair for the rest of your life.

To: BGA Full and Assistant Instructors You will be aware that BGA RP 38 recommends that all glider cockpits should be equipped with cushions containing energy absorbing materials. These cushions are widely used in club gliders but less so in privately owned gliders. The BGA has produced a booklet explaining how safety cushions work and how they can reduce injury not just in a crash but in the heavy landings that occur from time to time on instructing flights. We are hoping the booklet will encourage all non-users to install energy absorbent cushions. You can download a copy of the booklet from http://www.gliding.co.uk/bgainfo/safety/documents/safetyfoam.pdf and your CFI has hard copy versions of the booklet for distribution. An EMail highlighting the issue and providing a link to the booklet will be sent to all private owners in the next few days. Please help us by encouraging all pilots to fly with a safety cushion.

[Aus-soaring] Fwd: NASA eBook: Breaking the Mishap Chain
Breaking the Mishap Chain: Human Factors Lessons Learned from Aerospace Accidents and Incidents in Research, Flight Test, and Development By Peter W. Merlin, Gregg A. Bendrick, and Dwight A. Holland This volume contains a collection of case studies of mishaps involving experimental aircraft, aerospace vehicles, and spacecraft in which human factors played a significant role. In all cases the engineers involved, the leaders and managers, and the operators (i.e., pilots and astronauts) were supremely qualified and by all accounts superior performers. Such accidents and incidents rarely resulted from a single cause but were the outcome of a chain of events in which altering at least one element might have prevented disaster. As such, this work is most certainly not an anthology of blame. It is offered as a learning tool so that future organizations, programs, and projects may not be destined to repeat the mistakes of the past. These lessons were learned at high material and personal costs and should not be lost to the pages of history. http://www.nasa.gov/connect/ebooks/break_mishap_chain_detail.html ___ Aus-soaring mailing list Aus-soaring@lists.internode.on.net To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring

[Aus-soaring] 50' obstacle clearance rule
Hi folks. My google-fu is failing me, but at least one of you can probably help. I've long accepted that the rule for obstacle clearance is 50'. However, the GFA instructor handbook describes it as a wingspan, and the B certificate oral exam calls 50' a recommended minimum, so I'm trying to go back to sources to find the origin of the rule. And I can't seem to find it written down anywhere. I'm beginning to suspect that my long-term acceptance of the 50' rule is wrong, and that the real limit is, shall we say, more operationally fluid than that. Wondering if the strict mention of 50' that I've seen at clubs all over Australia is actually more of a tradition, perhaps derived from a misunderstanding of certified light aircraft performance charts which give minimum takeoff distances including clearance of a 50' obstacle. Does anyone have a cite to the regulations? (while you're at it, providing a cite to a current GFA or non-exempted CASA regulation which states what GFA annual check entails, whether it's required to be signed out in a logbook, or whether an instructor is even required to be present, would help to settle a long-standing argument :) - mark ___ Aus-soaring mailing list Aus-soaring@lists.internode.on.net To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
Re: [Aus-soaring] 50' obstacle clearance rule
Great pickup.and for a 15 Metre aircraft the two are one and the same; and possibly this is where the history lies as documents were edited by different authors; it obviously requires clarification.

Re: [Aus-soaring] 50' obstacle clearance rule
Hi Mark, As a general comment, making mandatory rules for obstacle clearance for aircraft without a throttle lever seems a bit silly. If I'm faced with missing a tree by less than a wingspan or hitting the fence at the end of the paddock I know which one I will be choosing. And why would an ASH25 need twice the clearance that a Sparrowhawk does? Oh yes, the 90 deg banked turn onto final. Of course, leaving distance between yourself and the trees is good practice. It's not something for the rule book though. Untitled Document Cheers /Tim/ /tra dire e fare c'รจ mezzo il mare/ On 15/10/2012 13:17, Mark Newton wrote: Hi folks.

Agreed! Nevertheless, my received training and my experiences at various gliding operations have lead me to believe that that's what someone actually did, and I'm trying to get to the bottom of it. For instance, at a comp where I listened to a CD giving a briefing to the assembled multitudes in the day before the competition finish OD, saying, I'm a very poor judge of 50 feet, but I'm an excellent judge of safety. That CD clearly believed there was a 50' rule too, otherwise he'd not have worded his comment the way he did.
