Okay Ive looked and cant find a the answer, how do you figure out wing loading and where do you find the max or recommended wing loading for a canopy IE a pd 193 reserve? I know, this should be basic but I want to make sure what I think is correct thanks

Ideal wingloadings for performance vary widely between canopy models, brands AND sizes. Max wingloadings are published by each manufacture and is available on their websites. Recommended wingloading for a reserve is 1:1 (or less). People *do* load their reserves higher then that, but usually they understand the risks involved with that and what all that entails. Although, as seen with mani canopies, a lot of people *don't* understand...sad.

For recommended wing loadings for PD reserves:
http://www.performancedesigns.com/reserve.htm
Wing loading is a ratio of your exit weight (all geared up, ready to exit) per square footage of the canopy. For example, if your exit weight was 205 lbs, your win loading for the PD-193R would be 1.1:1. That would put you in the "Advanced" catagory for that reserve. Hope this helps.

PD Reserve wingloadings
Wing loading is calculated as exit weight (body, rig, clothes, helmet, the whole deal) divided by square footage. Ie 200 pounds out the door on a 150 is 1.33:1. 200 out the door on a 100 is 2:1

During the PIA Symposium, Brian Germain mentioned a very simple guideline for maximum wing loading.
less than 100 jumps 1.0
100 to 200 jumps 1.1
200 to 300 jumps 1.2
300 to 400 jumps 1.3
400 to 500 jumps 1.4
500 to 600 jumps 1.5
600 to 700 jumps 1.6
700 to 800 jumps 1.7
800 to 900 jumps 1.8
900 to 1000 jumps 1.9
over 1,000 jumps 2.0
Note that the second digit is matches how many hundred jumps you have.
The biggest problem - in skydiving today - is people down-sizing before they learn how to extract all possible performance from their old canopy.
