Recommended Canopy Size Can't Post

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)Shocked
I don't think so not yetWink........

The flying characteristics of the canopy have to be considered (of course). I was still shocked to see what it recommended for me.

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.

It seems you are unclear on the concept of what it's doing.

I am going to do the most un-guy thing of which I can think: I am going to ask directions. Where is the calculator?Smile

Yeah I was lost too - considering she said 'go to gear' it only makes sense that a guy would get lost when the woman gets the directions wrong Wink

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. Tongue

Leblanc has an article about wing loading on the PD web site. The shortest explanation I heard once:

"The 170 sq' and 105 sq' may have the same wing loading but they're flying in the same body of air molecules. Hence, the smaller canopy is the faster higher performance of the two."
