Thanks for the update, Tad.

I'm keeping my fingers crossed, and hoping you can get through this quickly.

I use a stronger weak link for the simple reason that low level weak link breaks are dangerous as the glider may not recover from the probable ensuing stall prior to hitting the ground.
This being said it is still far preferable to use low tow tension, headwind launch, and a standard weak link.
Does that mean the danger stated no longer exists when towing with low tension into the wind?
OBVIOUSLY. What Doc MEANT to say was that he uses a stronger weak link when towing with high tension downwind. Seems a bit counterintuitive because one would think that an extra effective bacon saver would be just the ticket for such a situation but these guys are professionals and you need to trust what they say.

The article was written in April, 1999.
I am curious to why you posted the above. Is it relevant or is it just for completeness?
It's a code. If you divide the sum of the digits in the year by the number of the month you get seven - the lucky number. It indicates that whether you use a one and a half G weak link for towing high tension downwind or a standard weak link for low tension upwind you should wind up in good shape.

Just to point out that all this has been discussed for a long time.
So much more intellectually stimulating than in sailplaning in the entire discussion in the entire history of the sport has been:

Mike Badley - 2014/09/03 16:13:30 UTC

Davis,
I know you feel frustrated that the mechanics of towing have been well understood for years.
Bulls-eye, dude. Makes it increasingly difficult for him to keep running his scams.
I still think it very worthwhile to continue discussing the issues. Gear changes, operations change and pilots change...
Yeah, if you hopped twenty years back in time you wouldn't recognize the towing scene as being from the same planet.
...so there's a continued need to rehash the known, experiment some, and possibly relearn some lessons already learned.
Always a student...
Certainly, grizzled old tow operators and pilots are not to be found at every tow operation.
Isn't that why we have the excellent book, Towing Aloft, by Dennis Pagen and Bill Bryden? It's a compilation of the wisdom of all the grizzled old tow operators and pilots.
Keep at it - and keep preaching the good stuff!
Like:
Davis Straub - 2014/08/29 17:26:54 UTC

I thought that I had made it clear that I want weaklinks and I want weaklinks to break to save the pilot's bacon.
Your advice and knowledge is well received out there amongst the congregation. Individuals with functional brains, not so much.
Davis Straub - 2014/09/03 18:34:44 UTC

Only the troll is frustrating.

It's a load of shit.
Jim Rooney says it's a load of shit. So why are you posting a load of shit here, Davis?
Guess you're not gonna answer that question 'cause that would be feeding the troll. And that's considered poor form - 'specially when you're preaching the good stuff to the congregation.
Mike Lake - 2014/09/03 19:51:30 UTC

Are you referring to me old boy?
Nah, he doesn't have the clout to get away with that on The Jack Show. So see if you can get him to answer the troll's question.

Medical update...

Had arranged for a ride to the clinic for this morning but as dawn approached I started realizing I wasn't gonna need it. As I started driving myself in I was feeling so functional that I considered turning around.

Major improvement over the wee hours. Looks like I've got the fever, loss of appetite, weakness stuff behind me. My doctor checked me out and we decided to wait and see before going to chest x-ray and antibiotics.

Serious lungs congestion issue seems to be diminishing.

Thanks for the well wishes.

Lucky chap to have his bacon saved, and also benefiting from another opportunity to perfect his landing skills.

I just do not understand why more folk don't get into this wonderful sport. Image

Yeah michael. That student let his nose get too high and the Davis Link did what was necessary to keep the situation under control. Bet he won't be making THAT mistake again.

Experienced some major aftershocks subsequent to my jaunt to the doc's - fever, long paralyzing headaches - and I'm still in pretty crappy shape with a serious cough but this is nirvana compared to that long dark stretch. That's the worst shape I've been in since the cancer trip in '83 - and this didn't feel all that far behind. (Still, if you're ever offered a choice between chemo nausea and just about anything else...)

I think, Michael170, you have to comprehend one thing...
I think, And, anything of any use you understand michael understands better.
...in terms of aviation, each and every landing in soaring...
I didn't see anything going on in the way of aviation, landing, or soaring.
...is of emergency kind (you can't go around and continue the flight).
That makes it an emergency? All hang glider, paraglider, parachute, sailplane, Space Shuttle landings are emergency landings? And conventional powered aircraft don't get an unlimited number of shots, ya know.
Therefore "saving your bacon" is part of the experience, so ability to "save your bacon" it's a required skill. Image
Sorry, And. I have zero interest in any of this "bacon saving" bullshit or its disciples. When *I* fly my purpose is to execute a flight plan - launch, climb to a predetermined altitude, work aforementioned lift as efficiently as possible, land where I want. If "saving your bacon" is part of the experience you're a fuckup and shouldn't be flying.
FAA Glider Flying Handbook

Aerotow Abnormal and Emergency Procedures

Mechanical equipment failure, environmental factors, and pilot error can cause abnormal aerotow occurrences during climb-out. Mechanical equipment failures can be caused by towline and towhook failures, towplane mechanical failures, and glider mechanical failures. Towline failure (one that breaks unexpectedly) can result from using a weak or worn towline. Towline failures can be avoided by using appropriately rated towline material, weak links when necessary, proper tow rings, and proper towline maintenance.

Towing Failures

Premature terminations of the tow have been a leading cause of glider accidents and incidents according to the Soaring Safety Foundation. Extension of spoilers/dive brakes, unlocked canopies, and other distractions are major causes of the tow failure incidents leading to a towline break. Prevention is achieved with the proper use checklists and proper prelaunch discipline. There are five planning situations regarding inmotion towline breaks, uncommanded release, or power loss of the towplane and are listed below. While the best course of action depends on many variables, such as runway length, airport environment, density altitude, and wind, all tow failures or emergency release have one thing in common: the need to maintain control of the glider. Two possibilities are stalling the glider or dragging a wingtip on the ground during a low altitude turn.
See how it works in REAL aviation? REAL pilots don't REACT to towline break EMERGENCIES...

You keep going ahead and ignoring us - along with grade school arithmetic - Davis. And we'll keep doing just the opposite with respect to you.

Kinsley Sykes - 2010/03/18 19:42:19 UTC

In the old threads there was a lot of info from a guy named Tad. Tad had a very strong opinion on weak link strength and it was a lot higher than most folks care for. I'd focus carefully on what folks who tow a lot have to say. Or Jim Rooney who is an excellent tug pilot. I tow with the "park provided" weak links. I think they are 130 pound Greenspot.

AndRand - 2013/10/27 22:32:44 UTC

Here in PL, there was similar accident couple of years ago. During tow launch pilot was on steep up course when bridle broke. The glider slipped backwards down on the keel from about 20-30ft.
I dont want to discuss details or consider what could be or shouldnt have been done, but it wasnt case of Next Set of Tubes.
It was fatal.
So why didn't this pilot on a steep up course when the bridle broke from about 20-30 ft. have the required skill he needed in order to keep himself alive?

Zach Marzec
Paul Tjaden - 2013/02/07

The tow aircraft was a Moyes Dragonfly with a 914 Rotax engine and was piloted by a highly experienced tow pilot. The tow line was approximately 250 feet long which is standard and Zach was using the "pro tow" method where the tow line is attached directly to a bridle on the pilot's harness and is not attached to the glider at all. A standard 130 pound test weak link was being used.

The launch started on the main runway at the north end (2,000 feet long) and was normal until at approximately 50 feet in altitude when the tow plane hit extremely strong lift elevating it quickly and abruptly. Because of the length of the tow line, it was a few seconds later when Zach's glider entered the same strong lift and he was at an estimated 100 to 150 feet in altitude at this time. When the lift/turbulence was encountered, the weak link on the tow line broke as the nose of the glider pitched up quickly to a very high angle of attack. Apparently, the glider stalled or possibly did a short tail slide and then stalled and then nosed down and tumbled.
...can extend beyond inconvenience?

The glider slipped backwards down on the keel from about 20-30ft.
Oh, so it was the glider's fault that it slipped backwards down on the keel from about 20 - 30 ft. and thus killing the pilot.

What was the make and model of that glider?
It was the pilot's fault. All he had to do was push the ignore button but he just froze.

To Michael170: please send pictures and information of your bridle and weaklink (if any). i'm anxious to see what you use personally and consider safer than what i use. trying to learn from all the experts
- It's just like THIS:

http://farm9.staticflickr.com/8394/8696380718_787dbc0005_o.png
Image

It's obviously just fine 'cause it's got an enormously long track record, nobody's ever had a problem with it that's contributed to a crash, and no advisory has been issued in the span of the nineteen plus months since your buddy / Currituck colleague Zack Marzec was killed on it.

- Show us what YOU use, motherfucker. Tell us:
-- why it's better than anything else you've previously considered
-- what:
--- glider model and size you're flying
--- what you're using for a weak link, how it translates to towline tension, and what your expectations of it are

- Why aren't you asking Jim Keen-Intellect Rooney?

- What's an "expert"? Tell me something about towing that can be understood by an "expert" that can't be thoroughly understood by a junior high kid who's never been near a glider.

- What makes you think michael's an "expert"? Can you quote me something in which he's claimed to be one?

- Do you only listen to "experts"? Can you give us a list of names that make your cut?

- How come you're not asking And for a description of the tow setup that got his guy killed? Isn't knowing what NOT to do every bit as important as knowing what TO do?

- Any comment on this recent trend of using substantially more dangerous weak links for the sole purpose of decreasing the inconvenience of the towing operation? We had a proven system that worked with a track record of quite literally hundreds of thousands of tows and now we're scrapping it just to give us reasonable shots at soaring windows? What's this world coming to? Sure isn't much like the one I knew.

Go ahead, peanuts, keep writing stuff. The only moves you have available are backwards and down.
