I think everyone should master the PLF first, but the PLF and slide are different tools for different scenarios. The PLF is designed for a high vertical speed, and works by converting that vertical speed to horizontal. It was developed in the days of round parachutes. Sliding is intended for landings where you've successfully arrested your vertical descent, but your horizontal speed is too fast to run. In this scenario, assuming proficiency in both techniques on terrain where both can be done safely, sliding is better. Quote Share this post Link to post Share on other sites

I wore a brace, as suggested by my surgeon, because twisting the ankle was one of the big concerns since I had relearned to walk/run. We already talked about butt vs. hip, but the sliding technique I learned and recommend (with professional instruction and coaching) is to go straight to your hip without touching your feet first. The only way I know to touch feet first when you're too fast to run is to slide on them, which (1) is tricky and hazardous and (2) defeats the purpose of sliding on your hip. If you're skilled enough to slide on your feet safely, why not just continue sliding on them until you're slow enough to run? Quote Share this post Link to post Share on other sites

I'm not the whoever person you folks think I am on some new account. Any of the mods should be able to track my IP and see that. Here's the thread. The best constructive feedback I received was to upsize, which was already part of the game plan. I did not jump until my surgeon said I was physically healed to do any and all physical activities I desire, including skydiving. He has a full understanding of what I did and my desire to fly again and cleared me when he saw fit to. It wasn't a dig, and I wasn't implying that, I was simply unable to find the post you just linked to when I looked at your posts from your profile. By my account you actually received plenty of constructive feedback in that thread, and important discussion amount the potential risks of landing butt first. Here was one from PChapman that was spot on: Quote Normally one tries to slide while twisted a bit to the side, trying to slide on one butt cheek. (Pretty much the 'baseball slide' if I have the terminology right.) Thus if you drop down suddenly a bit, or you hit a bump, you don't smack down straight on your tailbone or compress the spine as suddenly. It might still hurt, but the shock to the spine will be less. That post got more responses than most do in the Gear and Rigging forum typically get nowadays. I think my initial analysis still stands, you got replies, they just weren't what you wanted to hear. I didn't anticipate that you were also upset over a few jokes about butts, how were we to know that your feelings were as fragile as your ankle.

I am a round student, both in the military and civilian. First skydiving rig was a paracommander. And, I have swooped a canopy @ 1.8 WL, bled it off, and still did PLFs. The only time I did butt slides was as a TI and even then it was very infrequently and out of concern for the student hurting themselves. Quote Share this post Link to post Share on other sites
wmw999 2,120 #30 November 30, 2021 I PLF when I'm going forward too fast (often), as well as going down too fast (rare), or just not feeling good about the landing. I probably stand up about 50% of my landings; far fewer in no-wind consitions. I've had excellent luck with PLFing on rounds and squares. Wendy P.

There's nothing wrong with PLF and you can do it all you want without any criticism from me. But please don't advocate against others learning newer techniques from professional coaches just because you've chosen not to learn them yourself.

Maybe, then, you should acknowledge that maybe, just maybe, people who can't run out their landings, might not also be able to slide them because it's their judgment of the landing speed that's the problem, not their running ability. And unless you're damn sure that you don't have to much downward speed, I'll still contend that a slide is a riskier move than a PLF.

Agreed. If there's one constant out there, it's that people misjudge landings - specifically vertical rate when you get to zero altitude. And when that happens, you are better off absorbing the impact with your legs than with your spine. "But my ankle is weak and I might break it!" - Yep. But better a broken ankle than paralysis.

Of course. I don't know why you're saying "maybe" three times as if you're sure I'd disagree. I think I've made it abundantly clear that sliding isn't for everyone and that my recommendation is to learn the technique from a professional coach. If there are missing prerequisite skills, they will be put on the right path for them. 4 hours ago, wmw999 said: And unless you're damn sure that you don't have to much downward speed, I'll still contend that a slide is a riskier move than a PLF. I agree with this as well. When I slide, I've already been moving horizontally just above the ground with zero downward speed. There is no vertical speed to mis-judge. 3 hours ago, billvon said: And when that happens, you are better off absorbing the impact with your legs than with your spine. I've already explained at least once in this thread that the proper technique has the femur absorbing the impact and not the spine. If you're coming down with anywhere near enough vertical energy to break your femur, I would absolutely recommend a PLF. I honestly can't believe you guys. I'm not trying to convince anyone to slide. I'm saying it's an option people can talk to their coaches about if they want to. And you guys are saying what? Don't talk to your professional canopy coach about it, we know better? That's really a disservice to the community. Quote Share this post Link to post Share on other sites

That's really a disservice to the community. I can't speak for the others, but my own aversion against slidings has nothing to do with your arguments. It's due to all the people who are rock-solid convinced that any stand-up landing is a perfect landing, that PLFs are for N00Bs, that slidings are better than PLFs because they are (name the excuse). You on the other hand are saying that the sliding is an advanced landing technique which may be applicable in some circumstances provided that you first learned how to do them in controlled circumstances with feedback of an expert. You are right. But for a large part of people that's not going to be the take home message. To sum up, the standard approach to any landing in dodgy circumstances - or perhaps to any landing, period - should be "PLF, unless..."

Your memory 'isn't serving' very well SLA, not PLF. Symbionese Liberation Army And I'll restate what I said in the original thread: PLFs are a basic technique every jumper should know. They allow a jumper to walk (limping a little bit) away from impacts that would break bones normally. They work well for both high vertical speeds as well as high horizontal ones. I've had a partial canopy collapse at about 25'. I've ended up with about a 10mph tailwind. PLF'd & walked away from both. Slides are a fairly advanced technique. They require training & practice and don't work in a lot of situations where a PLF will. Quote Share this post Link to post Share on other sites

An aversion to PLFs is an invitation to a sprained ankle, broken ankle or something more serious. If the brain isn't in gear on landing the bones or muscles in the body may get the gears.

Someone correct me if I’m wrong but I’m pretty sure that the way hard, non-bendy objects absorb impact energy is by breaking. When they don’t they just transfer it all to the next component in line.
