Weight shift while aerotowing
Davis Straub - 2018/03/30 12:00:58 UTC
This is what Jim Prahl tells me.
Why's he telling YOU? Why isn't in engaging in discussions with US?
Most people are used to moving with their shoulders to the left or right within the control frame as a means of shifting their weight.
- Most people don't fly hang gliders.
- So where are you getting your data about what most people do and don't do when they're flying hang gliders?
When aerotowing you need to be sure to move your whole body, as though it were a straight board, pivoting around a point about three foot in front of the center of the control frame. If you want to move to the right you move your whole body as though it were a board, to the right with your toes furthest to the right.
And here I was thinking that we had a Pilot Proficiency System to ensure that people were qualified to perform in accordance with the ratings and skills in which they had signoffs.
This means that your head will stay fairly close to the center of the base tube, while the rest of your body is to the side. You don't just shove your butt to the side, but your whole body.
This is an XC comp that people come great distances to participate in. One would think that most of them would have solid Two skills regarding roll control.
If you don't do this, and move with your shoulders the upper part of your body and your head to the side, the glider will yaw to the other side. Move this way to the right, the glider will yaw to the left.
For example:
In the photo (not a high resolution photo)...
Better than most of the low resolution crap we've had made available to date.
...you can see that while the pilot's head and chest are to the pilot's right, his legs and feet are to the left.
And you can see the violin string tight towline pulling his shoulders (ONLY) nearly sidewise with a tension limit of four hundred pounds. And I think that he's probably doing everything of which he's physically capable at this point and realizes that nothing's gonna really matter anyway.
This means that the glider is going to yaw to the left.
The glider is ROLLED and literally on its ear and locked out.
If the left wing is touching the ground, that's certainly not going to help.
You mean like the tug driver you're conspicuously not saying anything about?

What's the difference between Jim Prahl WRITING and Jim Prahl TELLING YOU?
In this particular incident...
In THIS PARTICULAR incident? What are the ones you're not telling us about?
I did not see the angle on the cart or body position prior to the launch.
Indicating you were not the driver everybody's being so careful not to identify. Not so much as a gender specific pronoun to confirm what I've already figured out.
If the glider was trying to launch with a higher than normal angle...
The glider WON'T try to launch with a higher than normal angle. It will trim to something reasonable when sufficient airspeed is attained. And we're not seeing any actual evidence or hearing any actual accounts of it ever having been excessively nose high.
...make sure you don't lock your arms during the initial roll.
How 'bout confirming the identity of this guy and telling us about his qualifications, ratings, experience and who signed him off?
Let the tow line pull you to your chest over the control bar into the position it would be at trim or best glide.
Doesn't his position depend a lot on whether he's flying two point or pro toad? And this guy's flying pro toad so obviously he must be a pro.
Hold that position. The tail usually raises and all goes well.
Funny it didn't this time. Also that we don't hear anything about any help he might have had or missed with somebody on a wire helping get him up to safe speed.
Also in the photos so far, really not much weight was moved with the cross controlling at the beginning.
In the photos so far he's locked out. From Photo One we can tell things aren't gonna end well if the tow isn't immediately terminated.
When the right wing rises at launch, and not being a coordinated turn, your lower body wants to hang to the left and you have to physically get more weight to the high wing.
Yeah, this is all the stupid muppet's fault. Nothing to do with conditions, total shit equipment, a new underqualified tug driver not monitoring what was going on behind her in the mirror, assuming everything was going great and maintaining afterburners until the violent catastrophic impact.
You also have to resist the towline from pulling your shoulders over.
Yeah?

Four hundred pound weak link you assholes use to put little girl gliders up. Tell me how your resist that pull when the tug's at full power, the tug and glider are going different directions, and the glider's already locked out and on its ear.
