Skydive SAFETY – The CRUX
Dan's Dan's Thought for the Day...
Tracking away from other skydivers well is one of the most vital survival skills a skydiver can have. No matter what kind of skydive you do (unless a Mr Bill or a solo) you will track to achieve horizontal separation from the others before deploying your parachute. Failure to track well and straight can result in collisions with other skydivers as you deploy, with potentially fatal consequences.
For these reasons, tracking well and straight is also an absolute requirement to do larger-way skydives. Big-way organizers will cut you from the jump if you can’t track.
Tracking is a skill we may think we have when we graduate from the Skydiver Training Program. However, like most other skills you learned as a student, the track is only a starting point. As you jump more and more, you should continue to work on tracking better – flatter and farther – on every jump.
It has often been said that you have no friends below breakoff
A flat track is one where you fall slower and move forward more rapidly (a flatter glide angle). In the same amount of altitude (i.e., from breakoff to deployment altitudes), a skydiver tracking flat will gain more horizontal separation from the center of the formation than someone in a steeper delta dive.
Simply because it will save your life. The goal of breakoff and tracking is to get as far as possible away from those mofos you’ve been flying with so you can all deploy your parachutes in clean air. It has often been said that you have no friends below breakoff, and this is very true! If you’re close to others horizontally, if the low jumper pulls (or if the high jumper cuts away), the high jumper who’s still in freefall can fall through the low jumper’s canopy as they decelerate. Or an off-heading opening between jumpers who are near each other horizontally can result in a canopy collision/wrap. None of these scenarios carry high expectations of survival. Particularly with highly loaded canopies, you might be surprised at how much ground they can cover just after opening, even with the brakes stowed.
Not one of us is immune to a collision based on experience or time in the sport; only through good breakoff plans, constant awareness of others around us, and good tracking technique can we reduce our risks of collisions during breakoff and deployment.
You may ask, “If flat tracking is so awesome, why didn’t I learn it as a student?” Excellent question! Most students are not taught a super flat track because it is a less stable body position with a higher center of gravity, and thus harder to master. As a student, if you are able to break off, track straight, and pull on time, you will pass the tracking requirements.
The student delta track maintains a good arch, legs straight with feet slightly apart, and arms swept back in a triangle shape with your body. When you transition into this body position, you may feel that you’re covering a lot of ground because you can feel and hear the increased wind noise. However, a significant part of this acceleration is downward, which doesn’t help out your horizontal separation goals at all.
In comparison, a flat track body position has the legs tight together and straight (with toes pointed), front of the body completely straight to very slightly de-arched, and arms tight to your sides. You are turning your body into a single efficient wing with more lift, and as such it should have smooth, straight lines. In this body position, you will fall slower than your normal neutral belly position and achieve significant forward movement.
It takes time and practice to master this position and be able to maneuver as needed. Because it is less stable, a minor issue like a dropped shoulder can cause a barrel roll right at the time it’s most inconvenient. As you work your way into this position, do it gradually over many jumps to maintain safety. Don’t punch into a new body position all at once at breakoff! Start with the track you know, and then work on making it ever more effective as you are able by:
Once you achieve this effective tracking body position, use it and refine it on every skydive. If you think your flat track is good enough… it probably isn’t! Never stop working on your track, because it certainly can’t hurt and it will save your life.
If you think your flat track is good enough… it probably isn’t!
We sometimes see heavier jumpers tracking lazily because they think they can’t track well with their body type. We also sometimes see lighter jumpers track lazily because they figure their long limbs and light weight mean they are guaranteed to track well. Neither is true! Regardless of your body type, you can probably track a lot flatter than you think by using these techniques. I’ve seen many a lightweight jumper get passed up by heavier jumpers who tracked with better technique.
Also, large-framed jumpers have some advantage in that their wide shoulders have a lot of surface area to generate lift.
Three points of caution regarding this effective tracking position:
You will never know how many incidents you avoided by tracking well – and that’s A-OK.
