I can understand the term "weather vane". That's what gliders tend to do naturally. But if you're standing in a strong crosswind on a steep slope and the outboard wing starts lifting, the list of choices look like this (with combinations possible):Nobody wrote:Indeed. Look up "weather vain" when you get some free time.

If it works well for you, then by all means, don't let me interfere with your continued success.Nobody wrote:#5 has worked well for me.
Yeah, I probably don't get it 'cause it's a totally imaginary problem.This is what Tad doesn't seem to get.
Sure. If you're stating that it must be true. It's OBVIOUSLY not gonna get EASIER if the glider's floating in the wind and taking all the weight off of your arms and shoulders.He doesn't seem to understand that any lifting of the pilot's body reduces the pilot's ability to control the glider on the ground.
- If you're defining "us" as the US hang gliding population at large, the kind of hook-in check that most of us do is a hang check at the back of the ramp one to fifteen minutes prior to launch.But in difficult conditions he's risking a big problem to solve something that could be more safely and easily solved with the kind of hook in check that most of us do.
Dude! I was trying to torque my glider into the wind but my feet just kept slipping on the...Frictional forces are typically defined as the product of the coefficient of friction (a property of the surfaces)...
Dude! I was trying to torque my U2 160 into the wind but my feet just kept slipping when I had my nose up enough to generate the ten pounds of lift I needed to feel my leg loops tugging.As the glider begins to lift you, you lose some of that normal force and you proportionally lose your ability to apply torque to the glider.
Yeah. We hear the laments of people with this problem so much - and those are just the ones who survived the torque failures in good enough shape to still be able to communicate.As the glider begins to lift you, you lose some of that normal force and you proportionally lose your ability to apply torque to the glider.
Yeah, RAPIDLY. Especially for your taller pilots.If you combine this with the rapidly increasing forces as you elevate the glider into the wind...
If you can't control the pitch to whatever degree of lift you want then you're almost certainly in the wrong sport....you're creating a situation where it's much more likely for the glider to get out of control.
Yeah, we've even got a special term for them - Hang Ones.Now I know there are excellent pilots with such highly refined instincts and reactions, that this is not a problem.
With or without their gliders. The important thing is to get safely off the hill. Details can always be ironed out later.But that's not the vast majority of weekend pilots who just want to get safely off the hill.
Bullshit.For them (and that includes me), it's much better to reduce the failure modes at launch by doing the hook in check with the safety of a crew holding the glider than it is to try to do two things at once (checking and launching).
And yet there are SO MANY PEOPLE - myself included - who, irrespective of hook-in check issues, deliberately hike the wing up in light air before they start their launch runs so it's better under control right from the start and doesn't hafta float up before it starts doing the job of lifting you.Checking is checking, and launching is launching.
Any way you could go back and put a comma and "e" in that sentence? There are occasions when I could really use that quote if you fixed it up a little.Bob you'r full of shit.
No ya don't. The strap always (so far anyway) becomes tight sometime in the course of the launch.Actually, I always launch with a tight hang strap.
- IF you're as connected to it as you're ASSUMING you are.That's when the glider lifts me off the hill.
- And what's stopping you from getting a wire crew? Not considered cool west of the Great Plains?But I don't tempt fate by sticking my glider up into the wind (without a wire crew!!)
Lemme 'splain sumpin' to ya, Bob... The purpose of this exercise IS NOT to "JUST TO SEE IF YOUR LEG STRAPS ARE TIGHT." The purpose of this exercise is to prevent forum postings like:...just to see if my leg straps are tight.
Just seeing that your leg straps are tight is a real good indication that your carabiner isn't dangling behind your knees when you're on the ramp.Holly Korzilius - 2005/10/01 18:19:55 UTC
Incident at 2005 Team Challenge
I don't have many details at this point, but I just got a call from Scott. Bill Priday launched from Whitwell without hooking in. Scott indicated there was about a hundred drop off from launch. Bill's status is unknown at this time. Please pray for him!
I will provide updates as I get them from Scott.
6. Don't stand in a strong crosswind and a steep slope without somebody on your outboard wing ... strongly recommended.But if you're standing in a strong crosswind on a steep slope and the outboard wing starts lifting, the list of choices look like this (with combinations possible):
1. Rotate the glider to pull the rising wing backward thus lowering its airspeed and lift (requiring torque)
2. Back up to pull the glider out of the lift band (reduces forces, but doesn't directly correct the imbalance)
3. Pull in to lower the angle of attack (reduces lift, but imbalance may continue due to different angles of attack on each wing)
4. Attempt to pull the rising wing down (which will accelerate it forward and worsen the imbalance ... not recommended)
5. Launch in a banked turn ... strongly NOT recommended
Sorry, I gotta go with Six. In fact, I think Six should actually be One in a list of one.Of these 5, the most effective (and rapid) correction is #1.
Wouldn't that help stop your feet from rotating whenever you tried to torque the glider and allow you to yaw it while maintaining ten pounds of lift to keep your suspension tight enough to feel?3. Pull in to lower the angle of attack (reduces lift, but imbalance may continue due to different angles of attack on each wing)
Next time you're out on the hill how 'bout putting a wind gauge into the flow at safe glider down and deadly glider up levels so we can quantify this. Better strap it to your wrist for the high position in case it gets torn out of your hand.Trying to accomplish this while the glider has been placed higher into the aiflow for a lift and tug only worsens the situation.
Who? Pat Denevan? Dennis Pagen? George Stebbins? Doug Hildreth? Rob Kells?I recently watched a pilot launch with a tight strap on a turbulent mountain launch.
AND ALL BECAUSE OF A TIGHT STRAP!!! Whoa! I never considered that before! Guess I need to seriously rethink a few things.He brought his own wire crew. The wire crew took their positions nose, keel and each wire. The glider was lifted up by all to tighten the strap. Each of the wire crew was calling out the pressure they were feeling on the glider. As the cycles blew through, the group would adjust the position of the glider in unison. They did this for about 15 minutes. Finally, the nose guy fell to the ground and the rest of the group and glider advanced. The pilot got off with a shakey launch.
All, of course, with their straps safely and thoroughly slackened the whole time between the hang check in the setup area and the point at which they left the ramp - including the fifteen minutes they waited for the evil lift and tugger to dick around and get airborne and plotted what they were gonna do to him in the LZ with no wuffos around.The rest of the plots made the normal nose down, run hard, launches.
But don't worry, that plot made the normal, nose down, run hard launch - not the least bit shaky! VERY confident, in fact.Raean Permenter - 1998/01/12 00:06
I talked with Bob's wife, Jeannie, and Bob Sunday morning. All considered, he's doing well. He's had two surgeries and had pins inserted in his wrists. The prognosis appears good. Jeannie said his injuries are broken bones in both wrists, a couple of fingers, right leg, and foot bones.
Not on every issue.Bob ain't full of shit...
And you're assuming he doesn't because?It's you that needs to get out a little more and fly the mountains.
At Jockeys Ridge in relatively light air I would frequently recruit a tourist to pull one of my stiff Comet wings down to help get me started on my first turn.#5 has worked well for me.
If something works for one person it will probably work for all of them. Aerodynamics generally aren't too concerned about individual personalities.If it works well for you, then by all means, don't let me interfere with your continued success.
I wouldn't worry too much about it.Bob, you're full of shit. Go learn how to launch with a tight hang strap!
