The Basic Wing Loading Formula

At its most basic, the concept of wing loading comes down to a very simple formula, in which one calculates the ratio of jumper exit weight to canopy size. Here?s the formula:

W ? C?= wing loading, where ?W? is exit weight in lbs and ?C? is the canopy?s surface area in square feet

For example, if you have a total exit weight of 190 lbs and fly a 190-square-foot canopy, your calculated wing loading would be:
190 ? 190 = 1, or 1 lbs per square foot, for a wing loading that would be generally referred to as ?1 to 1?
If your exit weight remains the same but you downsize to a 170-square-foot canopy, the formula looks like this:
190 ? 170 = 1.1176470588235294, or 1.1 lbs per square foot
If you made the (extremely poor) decision to snap-downsize to a 120-square-foot canopy, the math looks like this:
190 ? 120 =?1.58333333333333, or 1.6 lbs per square foot
A bigger number means?more: more?down, more?fast.

The Icarus Student is a mistake-friendly, fun and forgiving wing, which allows for more consistent flying in all situations. And she?s built tough to withstand rough handling!

Safety is more than just reducing injuries ? it?s also about prevention. We work under the methodology that easy = safe and safe = easy. ZP construction, Vectran 750 lines, contrasting brake lines and alternating color packing tabs optimize the new Icarus Student for durability and ease of use. Your students will be safer, for longer.

We gave her a 9-cell planform and modern shaping to make her responsive and increase predictability and ? voila! ? a student canopy that students will actually enjoy flying. This results in more confidence throughout the learning curve and unlocks faster progression.

Her flare is powerful and super forgiving to let new skydivers spend more time concentrating on progressing and less time with their faces embedded in the dirt.

Collapsible Pilot Chutes

Using a collapsible pilot chute will improve the performance of your canopy. The increase in performance gained depends on the size of the canopy and the wing loading. It is a balance between the two, rather than wing loading or canopy size individually, as the pilot chute size generally remains constant rather than reducing with the canopy size.

There are two types of collapsing systems in common use; the ?kill line? system and the ?bungee? system. We prefer the kill line, however, the bungee is easier to operate and requires less packing.

If you are using a class 3 or below (eg below 1.25 PSF) or canopies above 160 sf, this gain will be minimal and possibly not worth the complication (as in a student canopy situation). For Class 4 (1.25-1.65 PSF), or canopies between 160 and 120 sf, we recommend a collapsible pilot chute. Either a bungee system or a kill line is OK. For Class 5 and above (above 1.65 sf), and canopies below 120 sf, it is a a necessity. This situation requires a kill line, rather than a bungee, as the speeds you can reach leave a smaller range between a subterminal opening and a hell of acanopy swoop.

On small canopies, collapsing the pilot chute has a double effect. Firstly, the drag of the pilot chute has gone and secondly, when the pilot chute is inflated, it will drag the center of the canopy back – putting a slight ?V? in the canopy planform. This ?V? configuration increases the canopy drag considerably, as the flow of air is no longer running directly down the cell (which is relatively smooth), but at an angle across it (which is very rough due to the cells bulging between the ribs).

Imagine the cross section of a canopy at any point, then imagine the cross section 10 degrees off true ? this should illustrate the need for a collapsing pilot chute in this situation.

Another effect of an inflated pilot chute is to reduce the canopy’s recovery arc. On a highly loaded canopy with a large recovery arc, this arc may be reduced by as much as 30%, by pulling the canopy up short and not letting it dive for very long. This becomes especially relevant in two situations:

1. If you have been flying your canopy with an inflated pilot chute, then put a collapsing system on, you will need to increase the height of your hook turn as your canopy will be diving more and require more time to recover. This is a potentially dangerous trap. You will also be coming in faster horizontally, as your canopy will have accelerated more through this longer recovery arc and through less drag. It will be behaving like a smaller canopy.

2. If you are using a bungee system that may or may not stay collapsed during your swoop, you will have lost control of the height that your recovery arc will level out at. This is especially problematical if your pilot chute has been inflating behind you, without you knowing.

ZP Construction:

Our Icarus Student canopy is made entirely of ZP. This means she flies better than her F111 counterparts. ZP is also a lot tougher and will last longer. She?s built to deal with all the rough handling, rough packing, and dragging across the ground your students can give her!

ZP makes it a tiny bit harder for students to push the air out, but we know they can handle it. Not one ounce of longevity was sacrificed, so your Cost Per Jump on the canopy stays low. Have your students flying safer, for longer.

Standout Colour Scheme:

We didn?t design the Icarus Student colour scheme just for our newfound love of the colour pink (though that might have come into it somewhere). There are tangible benefits for your students hidden away in those conspicuous colours. And don?t worry; you can replace the pink with any colour of your choosing!

When your students are flying around at 4000ft the split colour lower surface makes it easy for whoever is counting canopies to see which ones they are. And it?s dead simple for instructors to check what way they?re flying to give them radio commands.

Plus when your students are packing the 50/50 colour scheme makes it glaringly obvious where the centre of the canopy is and where to start flaking ? from the centre black cell to the outer black cell.

Alternating Line tabs:

We?ve added alternating grey and white line tabs on the lower surface so your students can easily separate out the different line groups.

Contrasting Brake Lines:

And just to make packing that little bit simpler for new skydivers, we?ve made the brake lines on the Icarus Student black, to stand out against the other white lines. When your students are doing their line continuity checks this helps show them where the brake lines might be tangled or wrapped around other lines.

The brake line below the brake setting is still white, so when they start running their hands up they can see immediately if the brakes aren?t set.

These features combine to give new skydivers confidence to enjoy their first flights at your drop zone!
