Proof that wingsuit can go up?

Recommended Posts

Is this a proof, finally ;)? That you can gain altitude in wingsuit?

From Facebook, but no logon required. (click HD in the lower right corner):

We see this at practically every Performance Comp...been a known thing for years:P
Take a peek at some of the GPS logs; it's very clear where in speed rounds, competitors "pop" up sometimes as much as a couple of hundred feet from their glide path.

As far as this video goes...a wingsuiter flying flat, viewed from a highly-loaded canopy descending at a rapid rate does not suggest the wingsuiter is flying "up."

The "up" is a very temporary state of flight, not remotely sustained.
Spend some time looking at the speed rounds on Paralog. You'll find quite a few where there are relatively significant "climbs."

Moreover, even if the canopy was not descending, but instead magically hovering in one spot, the perspective is completely wrong to prove anything on this matter. The line from camera to horizon is a declining slope (since the ground is below the camera and the earth is round). Anything that passes under the camera and keeps moving forward will eventually cross that line. That the wingsuit crossed this line says nothing about whether his glide is negative, flat, or positive (only that it must be greater than the negative slope from camera to horizon).

But yes, it's certainly possible.

With all respect DSE, where do you see a "highly loaded canopy" as the reference point? the person with the camera is wearing a WS without collapsed arms either leg wings which are huge brakes against "rapid" descent of the "canopy". neither I doubt that the WS flyier filming the flaring WS guy is under Velocity to create such an visual illusion of climbing up the WS flyier. He went up for a limited time and height but he did.

Whether arms or legs are collapsed makes no difference to the descent rate of the canopy.:S

Granted, I *assume* it's a highly loaded canopy. It's Luke Aikens. I've seen Luke fly several times, and never under a "lightly loaded canopy." But for the sake of argument, you're correct in that I'm making an assumption.

Either way, this sort of video proves nothing, it's just a fun visual to see.

Wait, was it really debatable if canopy and wingsuits could gain altitude? Of course they can. All you have to do is change velocity into lift.



Exactly.

[cough cough]

What happened here a while back is that during the period where some new super-large 'mattress' suits were being released someone would occasionally claim that they made one 'fly up' and that this was proof of the awesomeness of the suit.

What would happen then is someone would suggest that they had been diving before this 'fly up' event and that this was in fact not so surprising, and maybe they would ask to see the GPS data.

This comment would have several possible outcomes but normally resulted in descending into brand wars with one or another person insisting that a particular model suit could 'fly up' and others saying it couldn't unless you were diving it to start with.

This has now led to further claims of video proof of wingsuits flying up, something which was never really in question in the first place.

Basically the Flying Up Wars can be seen in the context of the broader period of the great DZ.com Glide Ratio Conflict. In one instance I think one guy made a wingsuit at home and posted on here saying it did 5.1 or something like that (no video or GPS data or anything).
