How fast does a 98 sqft canopy land? (175 pound jumper, very experienced)

Depends on the control input. Straight in, 90 degree toggle turn, 90 degree front riser, etc...

It's going to be plenty fast just straight in anyway.

Only very experienced and current jumpers should be jumping them at that weight.

straight in

Impossible to answer. lots of variables affect speed. Wingloading, canopy design, temp., alt., etc.
A 175 pound jumper will be close to 200 out the door. that means wing loading will be close to 2:1

Bottom line: it will be very fast

is it for you?

roughly 40% faster than the same jumper with the same canopy of 190 sq ft.

It hooks in exponentially quicker when you are jumping a canopy even close to that and you don't have the experience for it and you didn't mean to make a low turn, but did because you don't have the skill or experience to be jumping that canopy.

I did the calculations and found this canopy with your body size and makeup + the air density + temp + buildings and cars + type of landing grass + humidity + dew point + every other factor in the entire world and found it to be 207.8759 MPH. This means once you touch the ground you will lose your left shoe first and than evaporate into thin air.


Keep in mind I had to make a lot of assumptions LMAO and none of my numbers or factors are anything more than total made up in my head while typing.


The real question is, how fast do you want it to go?

Strikes me that if you were experienced enough you wouldn't ask the question. I mean lets be honest its a pretty retarded question.

It really is a retarded question. Either way I would guess the forward speed to be in the mid 20mph range in a no wind condition.

If you factor in the descent component as well, your actual speed at impact is going to be more representative of a much higher speed.

Unless of course you flare the canopy, at which point all of these numbers are moot.

I don't know why it's a retarded question...I think you are both jackasses for your assumption that this is my canopy . Thanks for nothing

Dude, you totally forgot to correct for the change in gravity due to altitude and latitude. The increased distance from earth's center of mass will reduce the speed by 0.0049 MPH.

You'll have to excuse them, a lot of trolls or newbies come on here asking for permission to do things that are stupid or beyond their skill level. The fact that you are asking about it would imply that it might be for yourself, which is why I asked. If you really want some valuable information why don't you elaborate on your question and fill in your profile. People around here are particular about the profile thing, and sometimes it is for good reason.

Retarded is kind of harsh, but it's a question that's impossible to answer. My canopy comes in to land at speeds ranging from zero MPH to somewhere in the ballpark of 35 MPH (assuming I'm landing strait in) depending on how windy it is and wether I land upwind, downwind, or crosswind.

I suspect what you're really asking is "what is the approximate flight speed of X canopy at Y wingloading in strait and level flight, relative to the air?"

I don't know the answer to that either, but I'm guessing somewhere around 30-35 MPH. Maybe a little more if you've got a velo with the RDS and super-thin lines.

But if you really want to know, you need either a radar gun or a fancy GPS unit.

A liitle more than 30-35mph?
Swoopers have already flown through the entrygate of the course with horizontal speed exceeding 90mph...

"what is the approximate flight speed of X canopy at Y wingloading in strait and level flight, relative to the air?"

Thanks...this is how I should have phrased the question!

I jumped MANY (also a 101st Airborne paratrooper) years ago with modified round canopies and chest-mounted reserves. My son is currently doing an AFF program (look at video Brendan AFF 3 on here) and his instructors BURN their landings. One of them told me that he thought he was doing about 70mph (before flare) and I wondered if that was ball-park (I'm not accusing him of blowing smoke). I can see an A license being kind of snotty about my question but not a 'D'.

I've seen a note about a small parachute whose forward speed is 100mph...tracking with a wing suit jumper.

Yep... but they're not coming strait in, which is what the OP asked. The speed those guys build up in the course of their turn is easily double or triple what they'd be doing if they didn't do a 720 or whatever from 1200'. And a guy flying a 98 @ 1.9ish WL is downright conservative compared to the pros. And, that 90 mph (or whatever the actual record is) was almost certainly recorded in a downwind landing, so airspeed is probably 10-15 mph slower than groundspeed, which is what was measured.

Not knowing where you're at and who the guy is, all I can say is "it's possible". There are definately guys who are coming in a 70mph (post hook-turn).

Odds are though, unless the guys name can be found on the pro swoop circuit, he's not coming in nearly that quick, though he may think he is (i.e. not blowing smoke, just incorrect). The lack of a vehicle and proximity to the ground really affects our brain's judgement of speed. 40 or 50 MPH looks and feels hella-fast... I timed myself on a ski run once at an average of 30 mph. I swear to god it felt like 90.

Hey, fuck you shit-for-brains. I'm the first guy to give any real info, and you turn around and call me a jackass?

Further reading of the thread reveals that you didn't even ask the question properly, you weren't even sure what you wanted to know.

Welcome to the forum, and fuck you very much for nothing.

Nothing snotty, just messing around with you. I bet you smiled first before you got upset. If I did upset you with my post please forgive me.

I am sure he could be going that fast and even faster with hooking it in. Hope your son sticks to it and gets his A lic. Tell him to keep posting his progress here. I promise to be behaved.

sorry guys...I don't think it's a dumb question but I shouldn't have reacted the way I did.

Thanks for the (generally!) polite and informative responses,

Only way to find out is with a radar gun, and a swoop

there is an instructor at my dz that was clocked in at 63mph on a 90 sq ft canopy and he probably weights around 190. We have a radar gun at the dz so thats how he knew he was going 63.

It's generally not a good idea to refer to a successful swoop as, "hooking it in." Although I suppose "hooking it in" does generate quite a bit of speed, and so your statement was technically correct.

In a similar vein, it always sounds bad to me when another person asks while loading the plane, "anyone else gonna hit the pond?"
