USPA downsizing guidelines proposal

Recommended Posts

I got the message. I'm assuming it went out to anyone on Brian Germain's mailing list.

Is the chart officially recommended by the USPA now or something?



Brian is proposing it to USPA. The email said "Here is the new Downsizing Chart that I am proposing to the USPA Board of Directors. What do you think?"

Ah, ok.

It's a little different than what's in his book (recommended wingloadings seem lower, but I may not be reading it right)

I'd vote for it, though I doubt it will decrease the blood spilt... might reduce the deaths though.



I'd like to think so, but I don't know if it would or not.

I think doing something to make canopy coaching more available would be better (some sort of rating, etc..), but that's just my noob opinion.

I'm planning on taking the next Scott Miller course, but I wish I could get coaching from someone on a more regular basis. :)

I think the high weight/large size end is off. I jump a 269 loaded at 1.25 and I can tell you that while it's not as twitchy as smaller canopies, you can still put a tremendous amount of energy into the system. It takes a bit to get them going, but more importantly, it also takes correspondingly more effort to shut them down.

We tell really small people to be careful that at somepoint below 140 sf, performance quits scaling with canopy sizes and instead surges ahead. I think that a similar situation occurs at the higher end when you begin really loading these big canopies up. It may not be turning as hard a a 210 loaded at an identical WL, but it is a lot more technical of a flight.

Brian my only concern is that you are leaving small people (mostly women) at a disadvantage by them not getting to a WL of 1:1 within 500 jumps. Being a small woman I know all about short lines and that I can get more performance out of a 120 than some one at 1:1 on a 170, but stopping the ability to progress canopy wise after 200 jumps worries me. I've flow a 135 at .9 and you are very limited on things you can do with the canopy especially with the risers presure. On the other hand most women are not agressive and I know very few that have gone below a 120 so it's probably a mute point, but it's something I'd like you to think about. Because no matter what size you are if you are doing the right things to learn how to fly a canopy (like I did) you should have the ability to move on to the next level.
Fly it like you stole it!

I'm gonna have to say that the 1st jump minimum is way too low--plenty of students would totally eat it on those.......shoot enough eat it already on a 290, they need to start out on a canopy big enough for them to land somewhat okay in the far too common 'zero input freaked out no flare landing'.

Did you read the stuff about the adjustments for altitude? There is a big difference between someone at sea level and someone in CO. So basically add 30sq feet to those numbers for you and anyone else that jumps here in CO.
