A couple SSA 2020 convention presentations online...

First thanks to the volunteers who helped with recording,
and thanks to Spence for his work on the first presentation.
Sorry I didn't manage a better job with the audio.
Anyway, the talks a

1) Bail-Out Aftermath — Lessons Learned.

2) OSTIV: Motor-glider Unreliability: Examples, Systemic Problems, and Potential Systemic Improvements

Videos, abstracts, and slides are linked on my web site:
http://www.nadler.com/public/NadlerSoaringIndex.html

Enjoy,
Best Regards, Dave "YO"

Thanks, Dave.

I was hoping you'd be able to post videos for those of us that missed the presentations.

Thank you for sharing. This was on my short list but there were so many good ones that I couldn't get to them all.

Dave's motorglider talk was good, but the Arcus bailout was really good. It
confirmed what I've observed over decades of soaring: if you can get out of the
glider, the parachute will work and you will survive, often without injury.
Half-humorously, if you fly a two-seater, be sure the passenger is young, strong,
and highly trained (worked for Dave)!

"without injury" would have been nice.
The ground training I got (from Parachute Shop, Nashua NH)
made all the difference.

If you haven't already done so:
Get proper ground training from your nearest jump school,
covering how to do an emergency jump and landing.

Thanks Dave for the very informative presentations.
One take away is that static line will save more lives. I know of at least one recent case of a pilot who managed to bail out but did not deploy on time. Dave was one second or so from deployment to hitting the ground, you can do the math of how much time he was from hitting the ground before deployment, 0.1 second?
I never seen someone using static line in the US. I wonder why. How common is it in the rest of the world, and what procedures are used to ensure you don't deploy accidentally after landing, especially those of us who are not used to static line.

Hope it was helpful.

There have certainly been a few; I don't have stats.

Dave was one second or so from deployment to hitting the ground

Sorry if I wasn't clear: I was 1 second from impact when I got chute open.
I had between 7-15 seconds under canopy before impact, just enough to
grab toggles, turn into wind, and aim for the 'safer' spot I hit.

How common is it (static line) in the rest of the world...

Um, that's why all our gliders have the orange ring next to shoulder...

Most important: Get proper ground training on chute use!

Dave, I am definitely going to go out to the skydiving place and do that. I wonder if you would indulge a question or two? After the rudder pedal slammed back at some point you applied control inputs with the stick, opposite aileron I think? Was there any back pressure on the stick at all?

The stick felt kinda limp.
Could have been adrenaline made it feel that way, just don't know.

Dave,
Thank you for the fantastic presentation. We have all been eager to hear about the specifics of the accident from the PIC. It is a sobering reminder that we all need to hear again and again and again about preparedness.

Do you feel surviving egress from a non-functional glider at the top of a more typical climb like 4,000-6,000 ft with the same scenario would have been possible?
