Body Position Questions

Recommended Posts

Let me start by saying, forgive me if these questions have already been answered/debated in another thread.I am too lazy too search through years of posts, and maybe some answers/opinions have been rethought over the years.
1. I have noticed lately in some videos of very good w/s flyers that they seem to be arching their body instead of (slightly)de-arching (as stated in the only book I have read on wingsuiting as the optimal body position).Could this be due to suit design, or has the consensus on optimal body position been reversed.(and no I am not seeing some one who is trying to get down to another flyer)
2. I have also noticed experienced w/s pilots who are not closing up the leg wing at deployment time with no ill effects(twists).I too have to admit to doing this more than once (rushing/brain fart) and so far consider myself lucky not to have twists or spun up as a result.Is it not a huge issue as long as your pull sequence is fairly quick(as not to go head down) and symmetrical ? Or could it be newer suit design (ie:COG)
3.I hate to ask this one........but.....the whole "legs on your butt" flocking style..... is this not almost necessary for larger flocks to allow the last guy(s) out of the plane(s) to catch the flock? I mean if you have a flock of 20 or so and the lead guy is going all out, wouldn't it be pretty hard to catch, and if you did, you would probably only get there at break off time.Right or wrong?
Thanks for educating a noob.

1. In BASE, flyers will usually not fly 100% when skimming terrain, but will opt to fly at 70 to 80% too have range left to 'climb' relative to the ground in case they get to close. Hence, not always seeing '100%' body positions.

2. In Flocking, speeds are (more often than not) far from 100% flight, and especially with groups often flying at a nice working speed for the least capable flyer...these body positions also tend to be far from the 'all out' 100% positions you refer to.

3. In the first generation wingsuits, the angle of attack wasnt really built into the suit design (legwing vs armwing size) and a bit of a de-arch was needed to really fly the suit. In modern wingsuit design we now see a more flat body position bringing the optimal performance. With the larger legwing automaticly dipping the suit in the perfect angle of attack.

4. Some of the examples in books tend to slightly overdo the actual body position. Showing a more exaggurated version of what you actually need to do, to make it clear. The actual body position required is often a lot more subtle.

The biggest cause for linetwist is asymetry, canopy choice and shitty packing.
Though its hard to point to an excact cause for any one malfunction or line-twist, asymetry is often a big culprit.
Be it your body position during deployment, creating an un-even airflow, or one shoulder pushing more into a riser than the other due to looking back, or one leg hanging more in a legstrap than the opposing side. Its just one of many things that can cause twists related to asymetry.

Next to asymetry, canopy choice is ofcourse a big factor as well.
A 170 sq/ft spectre will usually behave a lot nicer than a 99 sq/ft stiletto.

Another factor is fullspeed pull or breaking before pulltime.
The speed redicaly influences the 'swing' you make under canopy, which in turn is influenced a lot by your legwing (and possible asymetry and amount of surface presented) which can spin your body a bit and/or create un-even riser pressure, resulting in spinning up.

And thats aside of other factors that influence twist.
Some people have little to no linetwists, others every single jumps. And often with the same of different gear. Its a case by case thing to evaluate...

If you have no issues during opening. Keep doing what you do...as it seems to be working.

No. Though 100% flying is definately almost impossible due to not having any range left, similar to trackingdives speeds can slowly be increased.

Often the base will fly at 50% to 60% the first 10 or 15 seconds and than slowly work his/her way towards the desired flying speeds.

But depending on the skills of the flyers, the wishes of the flyers, and for a large part also suits used, the actual flying speed can vary wildly.
And due to often compensating 'down' the forward speeds tend to drop more and more as the jump progresses.

Though this is certainly not a rule. Its a subject often topic of hot debate, but its definately getting better, and depending on where you go, you will find wildly varying choices in mode of flight.
Some fly it slow forward, some balistic. Some combine that with fast downward speeds, other like to push for full flight in both orientations.

In the end, its all flying your body. Be it near a stall, in freefall or cruising like a missile...its flying....not a right or wrong. But always with room for improvement for sure.

I feel better now ;)
Watching videos of myself in various suits, I always thought "dude why the hell are you arching?!" (you know better!)
At pull time I have to admit to being less comfortable than I should be, so therefore I was rushing a bit and not closing the leg but usually being symetrical so it didn't seem to be an issue, and then after watching a video recently of a really good w/s pilot in a yellow suit with a huge ass camera on his head ;) I noticed he wasn't closing his leg wing either......I guess I am not a total idiot after all.
Thank you for your reply

When it comes to skydiving and wingsuit flying in particular, a good one to always remember is "Slower is usually faster"

This goes for steering inputs, body position during deployment and reactions to what happens around you in general. Take your time, and do everything in full controll, instead of forcing your way through it via a series of unstable movements hidden in haste..
