Recommended Canopy Size
Go to gear and to wing load calculators and it calculates your recommend canopy size. I jump a 135 as of now. I load at .9. The chart calculation recommends I can jump a 108 loaded at 1.2 ( with my weight and gear) I don't think so not yet........
You have to change the loading percentage to be what you are lookin for. Something at 1.2 or something at .9. It will then tell you the square footage closest to what you need. Its not saying to fly at 1.2, thats just the default.
The other thing to consider is that not all wingloadings are created equal. If I weigh in at 170 and jump a 170 sq.ft. canopy, I will not experience the same flight characteristics as a 120 lb person flying an identical 120.
The person flying the 120 will still experience higher performance, even though the wingloading is identical, because the lines are shorter on the smaller canopy.
I downsized to a 120 from a 136. About the same time I lost a ton of weight. So the wingloadings are roghly the same. I'm here to tell you the 120 is definitely higher performance than the 136.
Don't ask me the physics behind it. I'll leave that to someone else.
