Body Language: Helping Your Canopy Open Better

Many factors determine the way your canopy opens. The design of the canopy and the way it is packed are two important factors, but body position also plays a major role.

We learn to deploy our canopies in a basic, stable position as students, and many of us don't give this skill much more thought after that. Unfortunately, we sometimes develop a few bad habits that have a negative effect on our openings.

Even after making thousands of jumps, people have been surprised to find that a few small adjustments to their body position during deployment can significantly improve their openings.

This article is about deploying a parachute, one of the most important things you do on every skydive. It might be a good idea to practice these techniques on the ground before trying them in the air. You might even want to make a solo jump and try some practice pulls using these techniques before it's actually time to deploy.

If you are not a licensed skydiver yet, or have just recently earned your license, you should discuss this article with your instructor before trying anything you read here. He or she may want you to focus on more important skills, like altitude awareness and basic stability, rather than adding anything new to your pull sequence.

No Need for Speed

The speed at which you are falling when you deploy your canopy can have a large effect on the forces generated during the opening. As your airspeed increases, these forces also increase.

Many of today's canopies are designed for relatively slow openings, and some will not be affected greatly by a little extra speed at deployment time. Some jumpers even find that their canopies open better when they are falling a bit faster. This is not something you should take for granted, though.

Higher airspeeds might not cause a canopy to open hard as long as everything else is just right, but small variables tend to have greater effects at higher airspeeds. If you rush your pack job one time and let things get a little sloppy, or if your canopy is starting to go out of trim, extra airspeed could make the difference between an opening that is slightly abrupt and one that really hurts.

Slowing down before you deploy can provide a greater "margin of error" and reduce the effects that other variables have on your openings. Slowing down can be especially helpful if your openings are frequently or even just occasionally faster than you like them to be.

Vertical or "freefly" body positions like head-down or sit-flying allow you to reach much higher airspeeds than "flat" body positions. This extra speed makes flattening out and slowing down before you pull particularly important. Both beginners and experienced freeflyers should keep this in mind when planning their dives. Even if you don't freefly, simply tracking at the end of a belly-to-earth jump can significantly increase your airspeed, and you may still find it helpful to "flare out" of the track and slow down before you deploy.

To flare out of a track, spread your arms and legs and de-arch slightly for a second as shown in. This will help bleed off any excess speed. Keep your arms and legs spread out and maintain a slight de-arch while you wave off, remembering to look around for other jumpers. As you finish your wave-off and start to pull, relax back into a normal arch. If done correctly this doesn't take a significant amount of time and becomes a natural part of your wave off.

What Are You Looking At?

Take a moment to notice where you are looking while you reach for your pilot chute. If you jump with a video camera, look at some of your openings on tape. What do you see in the video as you pull? Are you looking up at the horizon, or down at the ground below you? Do you look back toward your pilot chute handle as you reach for it? Do you look over your shoulder after you pull?

Older skydiving rigs used spring-loaded main pilot chutes activated by a ripcord. Even in the late 1990's this type of system was still used on most student rigs. Those of us who were trained using this type of system were taught to look for the ripcord handle before grabbing it. We were also taught to look over one shoulder and "check" after pulling the ripcord. Looking over your shoulder changes the airflow over your back and helps clear pilot chute hesitations, which are common when using a spring-loaded main pilot chute.

Most licensed jumpers use hand-deployed main pilot chutes, and these are becoming the standard for student training as well. Even if years have passed since they transitioned to a hand-deployed pilot chute, many experienced jumpers still have the habit of looking for their pilot chutes as they reach for them and checking over one shoulder after they throw them. Unfortunately, it's almost impossible to look over your shoulder and keep your shoulders level at the same time. Looking over your shoulder also tilts your container to one side.

Although large, docile student canopies may not get offended if your shoulders and container are uneven, more responsive sport canopies will be much happier if you keep your shoulders level. Having your shoulders and container tilted as the canopy deploys can cause off-heading openings, line twists, and can even cause a hard opening.

Most of us have our pilot chutes mounted on the bottom of the container, so trying to look for the handle is really useless. Even if you still use a legstrap-mounted pilot chute, you probably can't see the handle very easily in freefall. Since hand-deployed pilot chutes are thrown into the clean air next to your body, pilot chute hesitations rarely occur and checking over your shoulder every time isn't necessary.

Some people have a habit of looking straight down as they deploy. This tends to put you in a slightly head-low attitude, which can increase your airspeed slightly. It can also amplify the opening force your body feels, since this force will mainly be transmitted to your shoulders when the canopy reaches the end of the lines. Also, your legs may swing through a wider arc as the canopy sits you up in the harness, making the opening feel more abrupt.

Instead of looking for your handle or looking down at the ground, try lifting your head up and looking out at the horizon as you reach for your main deployment handle. This puts you in a more head-high attitude. The opening forces will be transmitted farther down through the harness instead of being concentrated at your shoulders.Looking at the horizon also helps keep your shoulders and container level as you pull.

After throwing the pilot chute, bring your arms back into a neutral freefall position and think about keeping your shoulders level as the deployment bag lifts off of your back. You can also push your hips down slightly and bend your knees just a bit, as if you were in a very slow backslide. This keeps your head and upper body high.

In the past, some jumpers have recommended "sitting up" during the deployment. This can actually work well as long as it is done correctly, but if you sit up too much or too soon there is a risk of increasing your airspeed or even becoming unstable. Simply lifting your chin, looking at the horizon, arching a bit more, and relaxing your legs slightly has a similar effect to consciously sitting up, and you're less likely to overdo it.

Some people who jump with side-mounted cameras believe it's necessary to keep their heads down when they deploy, to prevent a riser from hitting the camera. This might be an issue if you have narrow shoulders or wear your chest strap very tight, leaving less room between your risers. It also might be a problem if your camera sticks out from the side of your helmet quite a bit. It's best to minimize this problem by keeping side-mounted cameras as small, streamlined, and snag-free as possible. If you're convinced it's necessary to keep your chin down, at least keep a good arch and relax your lower legs to keep your shoulders higher than your hips, and also focus on keeping your arms and shoulders level in the relative wind.

Back in the Saddle

As soon as the canopy sits you upright in the harness, try putting your feet and knees together for the rest of the opening . Putting your legs together helps keep your weight even in the harness and reduces the chances of an off-heading opening. This is especially effective if you are jumping an elliptical-type canopy. Just the weight of your legs swinging around or a small weight shift in the harness can cause some of these canopies to start turning.

If you grab your risers as the canopy is opening it's best to hold the lower part of the risers, just above the 3-Ring system. If you grab the risers up near the toggles you might make the canopy turn by unintentionally pulling one riser or releasing one brake. If you hold on to the bottom of the risers, you can still slide your hands up quickly to steer with the risers or release the brakes if necessary.

Some jumpers try to keep their openings on heading by actively steering with their rear risers while the slider is still up against the canopy. This works with some canopies, but other canopies don't like it at all. You may get better results if you just relax, sit still, focus on keeping your weight even, and wait until the slider starts to come down before making any corrections with the risers.

Watch Where You're Going

In a first jump course we are taught to check our canopies to make sure they open correctly. Although this is important, it can also create a very bad habit. Many jumpers look up at their canopies as soon as they start to open, and continue watching the canopy through the entire opening sequence. Some people continue looking up for several more seconds while they collapse their sliders and release their brakes.

If another person opens close to you, you may only have a second or two to react in order to avoid a collision. Staring up at your canopy for five or ten seconds after you deploy is like driving down the highway while staring up at the roof of your car.

Fortunately, a few techniques can help you avoid this problem.

Many students are taught to count out loud while their canopy deploys, saying "arch, reach, pull, one thousand, two thousand, three thousand…" If you don't do this already it's a good habit to create, and can help you keep track of time during the deployment sequence.

You will hear and feel different things during each stage of the deployment. A second or less after you throw your pilot chute, you should feel the snatch force pull you upright in the harness. This is the force of the canopy fabric hitting the relative wind as it comes out of the deployment bag.

The canopy will then snivel. The snivel is the portion of the opening where the slider stays against the bottom of the canopy, reducing your airspeed before the canopy starts to inflate. There will still be a lot of wind noise during the snivel, and you will still have a sensation of falling. This may last for a second or two, or even for several seconds.

The inflation occurs as the slider moves down the lines and the cells fill with air. Things become quieter once the canopy inflates. Even under a canopy that inflates very slowly and smoothly, you will still feel the transition from falling to gliding. You may also hear the slider flapping above your head once it comes down.

Once you become more aware of these sensations you will find that your other senses can tell you as much about your opening, if not more, than your eyes do. Soon you will feel comfortable looking out in front of you during the entire opening, rather than watching the canopy itself. This allows you to watch for other jumpers, and many people find this reduces off-heading openings as well.

"But," you may ask, "if I don't watch my canopy open, how will I know if I'm having a malfunction?" Take the advice of someone who has cut away a number of misbehaving canopies: you will probably know right away if you are having a malfunction. They tend to feel very different from a normal opening, and you will probably know something is wrong before you ever look up.

If you start to count after throwing your pilot chute, and reach "two thousand" or "three thousand" without feeling the snatch force, there is obviously a problem. This would be an acceptable time to look back over your shoulder and check for a pilot chute hesitation or pilot chute in tow.

Once you know how many seconds the snivel usually lasts on your canopy, you will also know if that part of the opening is taking longer than normal. You can usually feel line twists right away, and if you start spinning wildly you'll surely want to look up at your canopy and see what's bothering it.

What if the opening feels perfectly normal? Unless you need to avoid another jumper right away, you should still look up and check your canopy right after it inflates. You might not notice a tear, broken line, or similar problem until you look up. Even in these situations, if the opening felt normal then the canopy is probably flying well enough to give you a low rate of descent. Assuming you deployed at a reasonable altitude, you should have enough time to do a control check and execute emergency procedures if necessary.

If you've been watching your canopy open every time then you might not feel ready to stop doing this during your very next jump, but you should start developing better habits as soon as possible. Start counting when you throw your pilot chute, and notice how long each stage of the deployment sequence takes. Pay attention to what you are hearing and feeling during the opening. Soon you won't need to watch the whole deployment, and will be able to pay more attention to your body and your surroundings.

Improving your body position and increasing your awareness when you deploy your canopy can produce great results. You might not remember everything in this article during your next jump, but at least think about trying these suggestions one at a time, at your own pace. You might be amazed by the difference a few small changes can make.
