PC in tow / manual pin pull

Recommended Posts

This was a response in the incidents forum, but I thought it might make a good starter here:

I've had two slight PC hesitations out of about 40 flights.

OK, that aside, I had a PC in tow once, not in a wing suit. I'm not sure what happened, probably closing loop was too tight. I pitched at 3 and had a little bit of room, so reached back and pulled the pin manually (one of the reasons why I always feel for the main pin cover in my OCD gear checks).

What do you think would happen in a wingsuit in that scenario? I know I can still reach back, but it's more difficult, and if any wing catches any air while doing it, it might cause a horseshoe. Any thoughts?

When I had this situation, I reached back and grabbed the PC, and just held it, then fired the reserve with the other hand. During the reserve inflation, the pin pulled, and I ended up reeling the bag in and stuffing it down my shirt. I tend to think that the movement of my body in response to opening shock (arms getting thrown forward) of the reserve actually extracted the pin.
If I was in the same situation again, i think I'd just re-toss the PC. If it was my case, then I think that would probably get the PC out of the burble, and give me a my main canopy. In the case of a really locked pin, it might actually make things worse (costing time, and leaving the PC waving around where it might entangle the reserve deployment). In either case, it sounds like your strategy (manually pulling the pin) would be the way to go.
How do you think it would cause a horseshoe? Wouldn't the PC already be out, eliminating the potential for a horseshoe?

A) My theory on why your main pin came out was is that your reserve container was empty, thus removing a lot of stress on the main pin.

B) The potential mal of which I speak would involve flipping over, which could cause either the bridle to catch a foot, or a riser to get under a wing.
