Re: [GreenMachine] PCA vs. Static Line

Which is better: PCA or Static Line?
I got a PM from GreenMachine, so thought I'd clarify my comment a little.
Static line and PCA each have their place, really. Neither one is really "better". In my opinion, strong points of a PCA include:
- A PCA does not require extra gear. If you get to the top of the object, and change your mind about freefalling it, you can always get a PCA.
- If done properly, a PCA does not shock the top of the canopy, so you can get marginally faster inflation.
Strong points of static line:
- Does not require a second jumper. This means you can do it if you're jumping solo, but it also means you can do it without putting any responsibility at all on someone else.
- Extremely repeatable. All other conditions being the same, you should get very similar results from two static line deployments.
With proper technique (vertical drop on exit, unstowing brakes with no canopy surge), it has been my experience that the static line technique can repeatably be used as low as about 130 feet, and can be used with great caution even lower than that. Although a PCA could potentially buy you a few extra feet, I tend to become concerned about repeatability well before altitude, and I lean toward static line.
I will use PCA, for convenience, on objects where I have enough altitude to deal with variability. I would also consider a PCA from a very experienced jumper on extraordinarily low objects, but it would have to be someone who I knew and trusted deeply.
