Collapsible Pilot Chutes

[Faicon9493 141]

I am currently jumping a Jedei 136 and a Vector II container. My pilot chute is the bungee cord type and it's time for a new one. I want to get a collapsible PC but I have some questions.

1. Best size?
2. ZP or F-111?
3. Can I install without taking it to a rigger?

I welcome your input. Thanks.

Its usually ZP 26-28".

Most likely it requires some work to get it connected.

1. If your current PC is working okay, stick with the same size. Adjust up or down a little if you change fabric types.
2. ZP gives more lift per square inch, but F-111 is less likely to slip out of the pouch.
3. Usually, but I've seen a few that were sewn to the D-bag (hate those!) or required tools to install. Either way, have it checked by a rigger or someone familiar with such things before you pack it up.

BTW, bungee PCs seem to work fine, but aren't too popular anymore. If you get a kill-line PC, be sure to double-check the PC collapse and kill-line window until it becomes second nature!

Hop-n-pop air speeds are an annoyance.

That and if you load much past about 1.3, you'll start to re-inflate with a bungee collapsible, then why even have one in the first place?

Look here for sizing info.

Quite a few container manufacturers use Cazers as OEM PCs. Unless the bridle is sown to the D-bag, it should be pretty easy to change out the PC.

50 donations so far. Give it a try.

Size...............27" diameter
Material..........ZP otherwise with a F111 you need a 36". The use of ZP
material will ensure that the porosity will not change unlike a F111. A ZP 27" packs smaller
than a 36" F111
Installation......If you are not used to pilot chute installation, do it with somebody having experience then
the next time you will know what to do.

Learn from others mistakes, you will never live long enough to make them all.

Does a non-collapsible PC generates harder openings? The snatch force is probably higher, since it reaches the line stretch full inflated and then suddenly stops. It also yanks on the bag, taking it of the canopy, still pulling on the canopy and disturbing (?) the pack job and maybe movng the slider down.

Is there any truth to that?

You need something to blame.

Negative. Force is proportional of size/area.

Please explain how the PC can pull the slider down!

I think he means "move the slider off the slider stops" as he was talking about "disturbing the packjob" before that.

Than what do you consider disturbing in a 120+ km/h wind?
