canopy size and jumps

Recommended Posts

In essence, I believe I have found a canopy selection that delivers balance between fun and safety and I will probably stay there, maybe even upsize in the future but I do not anticipate ever downsizing further.



Altough I have no/not much experience to fall back on yet, I feel exactly the same way. Right now, I have the feeling that I don't ever want to downsize any further and I am sure that my mindset will not change for a long time. But who knows, maby when I get 15 years in the sport and am very current I might start to think otherwise.

Hi guys:
This doesn’t relate to this thread 100%, however, I’ve been down for almost a month now because of my poor piloting/flair skills, so I’ve been researching and reading and reading some more…

Attached is a paper titled “The Aerodynamics and Piloting of High Peformance Ram-Air Parachutes” by Jerry Sobieski. It’s not what I call light reading, but it contains some very enlightening insights and helped me to truly comprehend many issues that go into piloting a canopy from “scientific” and practical view (I am embarrassed to admit many aspects of which were taught to me by my instructors, but just didn’t click 100%)…

Anyway, maybe someone else could find it useful. It was published in ’94, however, many fundamental concepts are there.
:D

EDIT: sorry, pdf was too large to upload, but here's a link to it http://www.afn.org/skydive/sta/highperf.pdf

Here are the canopies I've jumped most of the time. I demoed and borrowed a lot of other canopies too.

jumps 0-19: 265 student rigs (0.6 wingloading)
20-250: Falcon 215 (1.05)
251-499: Sabre 2 170 (1.45)
500-750: Crossfire 2 149 (1.65)
751-now: Katana 135 (1.9+)

jump #327: PD Reserve 160 (1.5)

23 Tandems: 360s, 380s (wingloading ever changing, from about 1.05 to 1.25)

Most of my 90 BASE jumps are on an Ace 280 (.85)
