4144 Review
Why? You've ignored damn near everything in my 4144 document and totally and deliberately misrepresented the tiny fragment you've bothered to skim.Eric Beckman - 2015/10/18 07:59
Sorry for ignoring your last post, Steve.
- Sorry.Death in family has occupied my time of late.
- And since you last weighed in there've been two deaths of highly experienced glider guys at organized events - the last one a week ago one of my localishes and a correspondent of mine.
Ditto for pretty much all of them.I mis-wrote my earlier post...
- His name's HewEtt....re: secondary back-up. Was referring to the Hewitt-style balanced release system using bicycle release with secondary triggered three-ring.
- Hewett's never really had a release system. His Infallible Weak Link makes one totally superfluous.
- What's a "balanced" release system?
- Hewett has NEVER used a Quallaby bicycle brake lever release "system". He started out with his inaccessible and deadly Rube Goldberg two stage panic snap tangle, converted to an inaccessible three-ring at the bridle apex, and then went to Peter Birren's inaccessible miracle Linknife.
- What's used for two point aerotowing owes NOTHING to Hewett. It's more in keeping with the Brooks Bridle which made Hewett's two-to-one "center-of-mass" tangle obsolete the nanosecond it got airborne.
- Oh. Then we're not talking secondary at all. We're talking total backup.Being a double release system, if either end fails to release, the other will still let the tow-line go.
- Right. There's a possibility that the top end will fail and a possibility that the bottom end will fail but it's mathematically impossible for...

I have a tandem rating!!!
...both ends to fail simultaneously. ('Cept in emergency simulations at altitude - never in the real deal down low.)Lauren Tjaden - 2008/03/23 22:20:15 UTC
When Jim got me locked out to the right, I couldn't keep the pitch of the glider with one hand for more than a second (the pressure was a zillion pounds, more or less), but the F'ing release slid around when I tried to hit it. The barrel release wouldn't work because we had too much pressure on it.
- And our carefully designed long thin Industry Standard bridles are totally incapable of...

pro tow set-up

Oh it happens.
I have, all the guys I work with have.
(Our average is 1 in 1,000 tows)
...in higher tension emergency situations.Oh yeah... an other fun fact for ya... ya know when it's far more likely to happen? During a lockout. When we're doing lockout training, the odds go from 1 in 1,000 to over 50/50.
Nah...I have never personally seen a "perfect" system that prevents any possibility of failure...

Can't release the tow line
Totally beyond the scope of human engineering. We've had some of the best minds on the planet brainstorming this stuff for decades. But they just couldn't figure out how to engineer a device to reliably let go of one end of a string under a couple hundred pounds of tension. So they conceded defeat and went to work for NASA putting rovers on Mars. Very sad situation.Davis Straub - 2015/08/03 13:05:54 UTC
Perfect.
Goddam YES! Correctly sized to 1.5 inches or less and a single loop of Cortland 130 lb. Greenspot braided Dacron Tolling line for each pilot and glider combination - whether the motherfucker likes it or not. Ya just can't argue with a track record that long....which is why it's so important to have a "correctly sized" weak-link for each pilot and glider combination.
Hard to imagine how anybody as astronomically clueless and stupid as you are could possibly be or ever have been curious about ANYTHING.I am curious about why having a back-up would get one killed though.
We have SO gotten this asshole right where we want him.
Don't mention it, Eric.Thanks,
Eric
