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 JFX was the last of our canopies to be designed purely by Jyro’s keen eye, 35+ years of experience and the inspiration of a few too many Heinekens. She was a new school wing done the old school way and like many classic things, she reeks of quality and reliability.

With the JFX 2 we’ve added a touch of fancy parametric curves and French Aerodynamic genius to her already smooth openings and toe-dragging charm.

The result? Incredible aerodynamics, refined performance and uncompromised aesthetics.

What can you expect when you fly your brand new JFX 2 for the first time?
First time flying a crossbraced wing? Your shaking hands will be steadied by the most predictable opening you’ve ever experienced, intuitive flight characteristics and stacks of flare.

The JFX2 is the smoothest transition to high performance wings. Loaded light or heavy she delivers consistently. If you’ve flown a JFX before you can expect a mix of the familiar with the new. The JFX 2 builds on all the positive vibes you got from your JFX, with the addition of more “energy”.

Who is the JFX 2 for?
The JFX 2 is perfect for experienced 9-cell elliptical pilots already pushing their wingloading on a non-crossbraced wing, who are looking for their first crossbraced canopy (with the supervision of a canopy coach) to expand their piloting skills safely. She’s a wonderful all-rounder that packs a serious punch for the weekend warrior, the team jumper, or the full time camera flyer.

Forget the stigma attached to crossbraced canopies – JFX 2 openings are predictable, soft and not scary! Reliable, consistent and stunning as always, openings are the ace card of this canopy.

Harness Inputs
Inputs are light and instinctive, and very responsive. She can be flown entirely on harness with ease – we actually prefer to fly a lot of harness with the JFX 2.

Powerful and responsive even at the bottom end – even more so than the original JFX.

Stall Point
The slow flight characteristics are hugely improved from the original JFX. The stall points is slower and lower – get plenty of feedback and warning, both on toggles and rears.

You can trust them! You feel very connected and it’s stable enough to give you fair warning before stalling. Rears are light and instinctive, the perfect option for long swoops.

Loaded high, lightly and even underloaded (light girls transitioning onto crossbraced wings, we feel your pain!), you’ll love the feedback of the JFX 2 fronts. You’re gonna need to slow the canopy down a little before your turn to reduce the pressure, but they are very effective for getting into the dive.

There is more than just a subtle improvement here – the wing feels fresh and re-energised. The JFX 2 is fun and predictable from opening to landing. Loaded lightly or highly you’ll never feel too far out of your comfort zone.

The dive on the JFX 2 is longer than the original JFX, but not as long as Leia. It’s easy to get this thing into a dive and maintain it. And with a slow, predictable (and easily adjustable) recovery arc, the JFX 2 is ideal to get those bigger rotations dialed in.

The bottom end flare is immense! Overall, the JFX 2 has more range and has the ability to fly slower – which means it stalls later, and has more flare. Trust us, you won’t feel like you’re lacking stopping power. Just another ace card retained (and improved) from the original JFX.


Of course she gets a Powerband, are you kidding?! The JFX 2 is joining the Powerband party with the rest of the Icarus range. Debuted on Petra, the Powerband lets us control the shape of the top surface of the wing more accurately, especially at the crucial leading edge where around 90% of lift is made!

MINYBRID CONTRUCTION (Sail loaded ribs )

A low-pack-volume take on our hybrid construction Leia’s, the JFX 2 pioneers the minimal hybrid (Minybrid) wing. The loaded ribs – the ones the lines are attached to that experience the highest amount of stress and distortion – are made of sail fabric. This reduces rib distortion, helping the wing maintain its shape through all flight profiles, increasing glide, stability and responsiveness. For construction reasons, these sail ribs will be white – but you can colour the non-loaded ribs and crossbraces however you like!


We’ve included mini ribs in the tail just like Petra and Leia. These little additions decrease trailing edge drag, which has the function of increasing glide and flare performance – both things you can never get enough of! Oh, and they look pretty awesome too, all matchy matchy with the colour you pick for the powerband!


The JFX 2’s sleek fully elliptical 21-chamber design captures the smoothed staged openings of the traditional 7-cell. She’s crisp and responsive, yet it does not feel tense and edgy, and packs some punch at the bottom end.


Don’t be fooled by how user-friendly this wing is. She holds all the benefits of her power enhancing, drag-reducing crossbracing. She’s gentle on openings, but she has an aggressive crossbraced swoop.


Inherited originally from the FX and VX, then redesigned for the JVX, the closed center chamber nose was the innovation that allowed crossbraced canopies to become popular by softening the openings, controlling distortion and improving aerodynamics. It’s not the latest but probably one of the most important of Jyro’s contributions to modern canopy design.


Vectran 500 is standard, or you can choose a black Vectran 400 if you are going for less drag, and don’t mind relining your canopy more often.


Parachutes aren’t a one size fits all. The JFX 2 is available in any size from 69 to 119 so that you can get the perfect wingloading for you at this stage in your canopy progression.
