Blowup your reserve....

[potatoman 0]

Hypopathetically.

Speedskyjumper is doing 500kph, loses track of altitude, and AAD fires, leaving you with a blown up reserve, probably body as well. Let's say, it split right down the centre cell.

What does the manual say about that one? Is it time to go to your main......

This time I will listen to YOUR thoughts.

You have the right to your opinion, and I have the right to tell you how Fu***** stupid it is.

If you are falling down with 500km/h and your AAD fires ( at the altitude it should), the blown reserve will be last of your concerns...

First the body parts will start falling off, IF the reserve menage to leave the freebag on time...so basically, that's all.

If the AAD misfire, read only the first part of the above.

If you are going 310 mph and your AAD fires at say 750 feet, you might impact before your reserve even finishes deploying.

Good luck on deploying your main.

Same thing is says about any reserve malfunction. If you tried everything you can to either fix it, or get it under some sort of control, and failed, dump the main. Get as much fabric out as possible.

Ditto for the reverse. If you have a main that you cannot control below your hard deck, dump the reserve. Get as much fabric out as possible.

If your only option is to hit the ground hard, do whatever you can to hit it 'less hard'. Make sure this is a 'last resort, and not something you do at 2000ft or even 1000ft. At those points, just keep trying, but at 500 ft, or 300ft, if you haven't come up with a solution, it's very bad form to go in without all your pins pulled.

If you could go 500KPH (310MPH) you would be experiencing 243.5 pounds per square foot dynamic pressure. I don't think you could get there from here.

If the canopy split right down the center cell it would probably be landable. This has happened before. The center cell collapsed but the rest of the canopy just closed the gap one cell short.

The upper force limit of TSO certification over the years was 5000 pounds (TSO C-23b) "Standard Category". This certification required no placarding as it is considered "Unlimited". No weight or speed limits. Reason: as Deyan says, your body parts would be distributed randomly.
No need for stronger stuff.

If your Cypres fires at 225m and you are doing 500km/h then i believe your Reserve might me undamaged. Simply because it only has 1,6 seconds to inflate. I am not sure it is going to inflate enough to get damaged.

If it does not cost anything you are the product.

Absolutely.

A friend of mine spiraled in after a low altitude canopy collision. He dumped his reserve but it didn't have time to inflate. However, when he impacted on his back, he feels the empty pack tray kept him from breaking his back, with no big lump of a packed reserve there.

Lovin every second of it!

I'm not sure what you mean by "get there from here" but the world record is 511 kph (averaged from ~8800ft to ~5500ft).

Yup, Jim Handbury on a canopy that he & Gary Douris were thinking of marketing.

I fell at 170 mph for my AFF jumps and much of my coaching. I can't imagine managing to do nearly twice that. Some instructors had a hard enough time keeping up with me, even when they were in a full head-down dive.

I'm actually not even sure I could get back to 170 now -- I lost about 30 pounds since then, and fall around 140 mph now.

I'm really glad I never had to experience a reserve opening when I was falling at 170. I have a feeling it'd still be teeth-rattling at 140.

I'm trying to teach myself how to set things on fire with my mind. Hey... is it hot in here?

You know, I don't remember, but he didn't break his spine after landing flat on his back. No life threatening injuries.


Unfortunately the other person in the collision did die.

The opening speed or time is relevant to the speed you are travelling. I believe TSO requires less than 300ft for opening on reserve, be it from standstill or from "terminal". So, 1sec should be enough to open it at that speed.

As for the bodyparts that might fly, Lightbulb. Why not have dynamic stretchy lines. Maybe you could use that to your advantage when swooping too....

You have the right to your opinion, and I have the right to tell you how Fu***** stupid it is.

I have opened a couple of reserves at "tandem terminal."
Ouch!
After the second tandem terminal opening, I needed a week - and the professional assistance of a massage therapist - to get the cramp out of my sprained neck muscle.

[riggerrob 643]

500 kph is far faster than solo terminal velocity (about 120 mph 200 kph).
500 kph is also faster than tandem terminal (about 180 mph or 288 kph).

Bottom line, the opening will be so painful, that you will be glad that it knocked you unconscious at line stretch!

As for injuries ... I hope you are not planning to do anything for the next month!

Several years ago a friend had a floating reserve handle during a headdown, reserve launched and ripped in half at the cell next to the center so he had 4 cells on one side and 2 on the other halfway inflated and spinning him. He launched his main and landed under a downplane, breaking his femur...

As for me and my house, we will serve the LORD...

Here is what is possible.

This is a handy tool to play with to calculate possible FF speeds.

If you change an input number you must change the altitude to get it to re-calculate.
