canopy sizes

[GaryRay 0]

i did some searches and came up with nothing on what im asking. i was wondering if there is a good weight to canopy size chart. i weigh about 190lbs and im jumping with the student rigs, i think what they told me is that im jumping with a 280 right now, im really not exactly sure what size canopy im jumping with but this weekend im gonna pay more attention to it. im continuing with AFF this weekend hoping to do atleast 3jumps, im on jump 4 right now. i failed 3 so i went to the tunnel and if the tunnel is anything like freefall, i think i will be pretty stable :). well now im just rambling so i will go sleep and check back tomorrow.

What you are asking about is called 'wing loading'

the link will direct you to tons of prior written material.

Go through that and your questions should be addressed, if not ask on this thread again...

First off.
Talk to your instructors at your DZ. They will know and have seen how you perform under canopy. They can give you advice based on first hand knowledge.

Second. If you must use the internet maybe this post will help USPA downsizing guidelines proposal

There is a document attached to the first post.

Good! Talk to your instructors more. Let them know you're serious about continuing with AFF and that you want to start learning more and more about gear. They should start showing and teaching you more about gear as you progress through the program, but speaking up yourself on your interest is a good thing.

My 2 cents... on student status you won't be jumping anything over or even near to a 1:1 wing loading. If you know what that means, my apologies, but in case you don't that means no more then 1lb of exit weight to 1 sq ft of canopy surface; and your exit weight includes You + Your gear. So, if you weigh 190lbs + 25lbs of gear that's 215lbs. Now if you're jumping a 280 sq ft canopy, that means... 215 / 280 = 0.77 or you're at about a 0.8 wing loading.

Looking down the road to when you're off of student status, my 2 cents again, but IMO... others will differ... you're better off staying close to a 1:1 wing loading for several hundred jumps or not much over 1:1, so, you're probably looking at a 210 or maybe a 190, depending on the design, as you're first canopy off of student status, if you stick with things.

Anyway, others will be along with advice too.


Remember, talk to your instructors, riggers and other experienced folk around the DZ. Bring them beer to drink at the end of the day.

The afore mentioned chart appears very conservative. This is a good thing.

No, they do not. The guidelines for BASE wingloading are totally different than for skydiving, as the conditions are different. And there is no such thing as "downsizing" for BASE. A canopy that skydivers would consider "beginner" or "effing huge" would be small or just right for BASE (e.g. a ratio of 0.6 to 0.7). Attempting to apply BASE wingloading guidelines to skydiving likely wouldn't get you into too much trouble, as they are more conservative, but do not attempt to apply skydiving wingloading guidelines to BASE. (Hopefully anyone interested in BASE would be asking this question on the BASE forum anyway, not here, or better getting some instruction.)

Looking for newbie rig, all components...

>The guidelines for BASE wingloading are totally different than for skydiving . . .

Indeed. When I started jumping I had a PD190 that I thought was too big. My BASE canopy was a Mojo 240 - and I quickly decided that was too small for me.

Yes..they do...as far as suspended weight in ratio to canopy surface area.



...wasn't talking about BASE canopy guidelines in a thread to a level 3 AFF student....

~by 'BASE jumpers canopies' wing load just like regular people's... I meant the math (weight & size) conversion.

If I would have said BASE jumpers 'wing load their canopies' just like regular people...Yes I would have been incorrect.

Bad wording I guess, I'll type slower.

1:1 is 1:1 no mater WHICH forum you go to.

i really appreciate the responses i got, helped me out a lot and that chart is pretty easy to read and im sure once i get a visual of what the canopy sizes are tomorrow it will make that much more sense.
