Reminder to Secure Your Carabiner to Your Riser!
NMERider - 2017/04/04 22:33:28 UTC
I caught this:
earlier today in my daily YouTube subscriptions.
Ain't it great the way these locking carabiners slash the danger of plummeting from our kites! Best thing to happen to hang gliding since the hang check.
I tactfully commented on it to the pilot on his video. We are also acquainted via social media. He was very responsive to the issue.
Hang glider drivers always are to issues that don't really matter. Almost as much as their propensities to leap at any opportunity to make some aspect of the sport more deadly.
Speaking of minor axis loading:

'Cept DELIBERATE. And nobody gets the tiniest bit bent outta shape about that one.
The frame still is during his landing flare...
Ain't it great the way a properly perfected landing flare slashes the danger of parking in a narrow dry riverbed with large rocks strewn all over the place! Best thing to happen to hang gliding since the u$hPa Four requirement for nailing three consecutive twenty-five foot radius spot landings.
...and yes, it was in this position from the moment he launched. Luckily it was a smooth flight without any of the wire slaps we've all been getting during our SoCal 'Spring Fling' <pun intended>.
Otherwise he'd have been in serious danger of exceeding his carabiner's two thousand pound minor axis rating and plummeting from his kite - with his parachute best left in its container to cushion his impact a bit. (Or maybe it would be better to throw the 'chute clear to reduce his weight, acceleration, terminal velocity. Hard to say for sure.)
I know this is an old topic but it cannot...
...as could his minor axis rotated carabiner...
...be over-stressed just like FTHI...
...stomp tests, Infallible Weak Links, easily reachable releases, pro toading, control tubes flying, stunt landings...
...etc.

There are several good ways to do this. I use the materials I have on hand.
Am I the ONLY person on the planet to simply use a few stitches to restrict the suspension loop size such that the only way the carabiner is able to rotate is with substantial effort during installation? ZERO:
- additional:
-- weight
-- drag
- interference with parachute "bridle" (extension) during deployment
It's a fake issue, Jonathan. If everybody DELIBERATELY connected minor axis for the next thousand years nobody would get scratched as a consequence. We've seen enough of these incidents clearly evidenced on videos - the tip of the iceberg - to be able to project that untold thousands of hours have been flown minor axis with ZERO noteworthy results. Gonna get a tiny degree of fuzzing on the webbing. And where's the post from/about somebody replacing his webbing due to this issue?
It's a weak link concept issue. The GLIDER's ALWAYS gonna break long before the minor access loaded carabiner.
And compare/contrast with the Quallaby butchered spinnaker shackle referenced above. THIS:
http://marine.wichard.com/images/prestations/A-WICHARD-2673-0003.jpg
is how the manufacturer obviously INTENDED its hardware to be configured and used.
- major axis
- two to one mechanical advantage lanyard
- not a lot of operational load capacity
THS:
http://www.flickr.com/photos/aerotowrelease/8305428629/
is how it SHOULD be employed IF it's gonna be deployed:
- Major axis.
- Two to one mechanical advantage for the lanyard (better 'cause you're using a pulley rather than dragging it over one side of the latch at an angle).
- AND - Towline tension split in half (nearly) by the two point bridle.
That minor axis issue - and similar/related ones - with respect to the core mechanism is pretty much the root cause of pretty much all towing crashes and fatalities. Gotta:
- put a bicycle brake lever within easy reach on a control tube to help pry it open in non emergency situations
- use an Infallible Weak Link to:
-- protect your cheap bent pin crap
-- release the pilot:
-- before he gets out of control
-- shortly:
--- after he gets out of control
--- before or after he slams in

My reserve fell out of the harness

I repacked it in the lz & jarred it several times & even held the harness by the carabinieri & spun it in a circle as hard as I could, like an olympic hammer throw, & it remained intact.
for the list:

Moronocity bar lowered to a hitherto unplumbed depth and nary an eyebrow raised.
