Why It Is Not Working: From Symptom to Cause in Skydiving
Unwanted spins, hard landings, a blank mind in the door: the diagnostic grid tracing your symptom back to body position, timing, harness fit or arousal.
Sport: Skydiving · Level: Beginner
Introduction
Almost everything that goes wrong in skydiving has more than one possible cause — and almost everything that really hurts happens near the ground. In a Swedish analysis of 539,885 jumps, only 2.7 percent of injuries occurred in freefall, but 87.9 percent under canopy and on landing [1]. The part that feels wildest is not the part that costs you.
This is not a technique guide. It says not how it is done right, but what your symptom means — and which of several possible causes applies to you. You read backwards: find the symptom, check the distinguishing feature, apply the fix, go deeper.
One line is fixed: anything to do with emergency and deployment procedures is learned under supervision — at your school, with repetition, with an instructor watching. Never from a text.
What You Need
Video from the outside. A coach or a video flyer. Your helmet camera shows everything except you.
A debrief the same day. Collecting footage does nothing, directed feedback does [2].
Exactly one focus point per jump. Your head carries no more than that under adrenaline [3].
A logbook with one honest sentence per jump — symptom, change, result.
Tunnel time as your laboratory. Troubleshooting belongs there, not in the jump [2].
Your break since the last jump, honestly noted. Currency is a diagnosis, not a character question.
Step by Step
The order is not arbitrary: first what you cannot train away, then what you can influence.
1. First Sort Out What Is Not a Technique Problem at All
Pain, numbness or dizziness after landing are not a training topic. Fear that will not let go of you on the ground belongs in a conversation with your school — not in the next jump. And everything around malfunctions, reserve and emergency procedures is deliberately absent here.
2. Then Gear and Fit
Harness, helmet, goggles, where your altimeter sits. An altimeter you cannot read in freefall is not an altitude-awareness problem. Nobody adjusts fit themselves — your school or a rigger checks it on the ground.
3. Then Body Position
Symmetry and arch come before everything else. Turns, fall rate and docking are consequences of the base shape, not separate projects.
4. Then Head and Task Load
High arousal narrows working memory — the accepted cognitive explanation for jumpers forgetting drills they perform perfectly on the ground [3]. So: one focus point, not five.
5. One Check Point per Jump
Your entire freefall account up to an A licence is about 19 minutes across at least 25 jumps [4]. Less time than one episode of a series — far too little to experiment in.
Common Mistakes
"I spin even though I want to lie still." Usually asymmetry, not a lack of strength. Tell them apart: when does the turn start? Right after exit, at a constant rate → an asymmetry you are holding: one shoulder or one leg lower. It starts when you reach for the altimeter or turn your head → your input, not your base shape. It arrives with acceleration and a curled-up feeling → de-arch. Fix: get symmetrical, hips forward. More in "The arch: why you fall stable".
"I always fall faster or slower than everyone else."Tell them apart: does it change within one jump? Yes → body position: fall rate depends on the surface you present to the air, not on willpower [5]. No, you are consistently faster than all → mass and surface, so build and suit, not a technique error. Slow only when you concentrate hard → you are braking unconsciously with a de-arch. Fix: change surface deliberately, not effort. More in "Controlled turns and fall-rate control".
"My turn always overshoots."Tell them apart: does the overshoot grow with the length of the turn? Yes → you never actively stopped the input. No, even small turns tip over → your input is too big. Only under time pressure → task load, not technique [3]. Fix: stop the turn deliberately, start smaller. More in "Controlled turns and fall-rate control".
"I never know my altitude in freefall."Tell them apart: what exactly is missing? You know the number on the ground but not in the air → arousal narrows your working memory, a documented mechanism [3]. You simply did not look → you lack the loop, not the perception. You look and read nothing → placement, glove, fogged goggles. Fix: name the cause first, then practise. More in "Altitude awareness and the pull routine".
"My landings are hard even though I do everything as briefed." Incorrect flare timing is the most frequently documented cause of landing injuries [6]. Tell them apart: what happens in the last second? You sink through the last metres → too early, the lift was already spent. You are still fast on touchdown → too late. Hard only in still air → your flare is fine, the ground speed is simply higher. Always the ankles → touchdown geometry; the lower extremity accounts for 47 to 59.7 percent of all injuries [7]. Fix: calibrate timing with a coach, not alone. More in "Canopy flight and a soft landing".
"On approach I decide too late and have to make a quick turn." The most dangerous symptom here: low, aggressive turns on approach sit at the centre of fatal accidents [7]. Tell them apart: You always end up long or short in the same direction → wind you did not plan for. You improvise every time → you have no fixed pattern. You only turn late when you miss the target → target fixation. Fix: the landing point is negotiable, the altitude buffer is not — and corrections low over the ground belong in supervised training, before your next jump. More in "Canopy piloting basics: pattern and approach".
"In the door my mind goes blank." Not a character flaw but physiology: cortisol rises in about 84 percent of jumpers, and the response does not disappear with experience [8]. Tell them apart: what exactly is gone? You can recite the sequence flawlessly on the ground but not in the door → arousal, not knowledge [3]. You were already unsure on the ground → a training gap, back to the briefing. Body calm and mind racing, or the other way round → two different levers. Fix: one single focus point, said out loud. More in "Overcoming the fear before the jump".
"My harness digs in, or I hang crooked."Tell them apart: when does it hurt? Only at opening → you slide into the harness because it is not snug enough. Throughout the canopy ride → size and fit. You hang crooked and the canopy pulls → check your own symmetry first, then the controls. Fix: never modify it yourself — school or rigger checks the fit on the ground, before your next jump.

Safety Notes
This guide diagnoses, it trains nothing. Malfunctions, reserve, cutaway, collisions, any kind of emergency procedure: not symptoms you look up, but drills that must be learned under supervision and by repetition — before your next jump, not after it. If you recognise yourself in one of those topics, the next step is an appointment with your school.
Second: adrenaline lies about pain. Stress-induced, endogenous pain suppression is documented in first-time jumpers [9]. A landing that still feels okay on the field can still be a fracture — and the lower extremity is the most common injury site [7]. Fix: get every hard touchdown checked the same day, do not decide the next morning.
And: persistent fear, poor sleep before jump days or the feeling that you have to jump are not a technique topic. That belongs in a conversation — with instructors, with jumpers, and with a doctor if needed.
Pro Tip
The most expensive thinking error in troubleshooting is experimenting in the jump. Every attempt costs you a run from a very small account: about 19 minutes of freefall across at least 25 jumps up to an A licence [4].
Move the troubleshooting to where repetition is cheap: the wind tunnel. Feedback-rich, repeated practice speeds up freefall motor learning for exactly that reason [2]. In the jump you then check just one point — and have it filmed from the outside.
FAQ
Why do I spin in freefall even though I am doing nothing?
Because "doing nothing" is also a position, and a slightly asymmetric position turns you reliably. Watch when the turn begins: right after exit and at a constant rate means a held asymmetry, only when you reach for the altimeter means an input, with acceleration and a curled-up feeling means de-arch.
Why do I land harder than others even though I flare?
Because the timing decides, not the flare itself — incorrect timing is the most frequently documented cause of landing injuries [6]. Sink through the last metres and you were early; still fast at touchdown and you were late. In still air everyone lands harder, and that is not a mistake.
Is it normal that I forget everything in the door?
Yes. Cortisol rises in about 84 percent of jumpers, and the response does not disappear with experience [8]. Under that arousal your working memory shrinks [3]. So: one focus point per jump — and the safety-critical drills have to be overlearned before you need them.
Am I more at risk as a beginner than experienced jumpers are?
For injuries, yes: novices carry the highest injury risk [6]. For fatalities the picture flips — those hit experienced jumpers disproportionately [10], usually through low, aggressive approaches [7]. Two different risks, two different antidotes.
Key Takeaways
Almost everything that hurts happens near the ground: only 2.7 percent of injuries occur in freefall, 87.9 percent under canopy and on landing [1].
If you spin unintentionally, the moment it starts names the cause: right after exit means a held asymmetry, at the reach for the altimeter means an input, with a curled-up feeling means de-arch.
Emergency and deployment procedures are deliberately absent from this guide: they belong in supervised training — before your next jump, not after it.
