Intentional cutaway

Recommended Posts

Did an intentional cutaway this afternoon at Otay. I was trying out Derek's old tertiary mount, which I got to fit my rig after some mods (Derek is skinnier than me and has a different ring arrangement on his rig.) I exited at around 3500, deployed the tersh main (PD170) and cut away at about 2200; was open by 1600 under a Silhouette 170, which is the main in my birdman rig. It was odd to have such a good view of the main as it was deploying - you deploy a tersh main on your back. Derek has a clever cutaway system on the tersh risers which uses simple tabs on captive cutaway cables so the cables stay with the risers.

The one further mod I want to make is to add harness rings to my harness. Right now I'm using two sets of mini-risers with standard harness rings. It seems to work OK but I worry about the the inactive riser interfering with the riser on the current main. It would probably be a piece of cake if I had chest rings, but as it stands it will take some sewing on a harness machine.

After I chopped I circled to see where the main would go; I had asked Buzz to keep an eye on the cutaway main. The wind was out of the southwest and so I flew about a half mile southwest before chopping. Unfortunately the winds were dead west at 2000 feet, and so Buzz ended up hiking a bit to get the main, which drifted down across the river (which is dry this time of year.) Now I face the fun prospect of untangling the PD170.

Now I'm ready for that Xaos 21! I also want to get some video of a few different types of mals, as well as some normal canopy flight, for a training tape some of us have been talking about.

I would like to be on some of that test jumping.

Too bad I am on the East Coast.

Enjoy and Be Safe!!!!!!!!!!!!!!!!!! :)

I would love a tersh rig... that would be so fun.. I would chop all the time:) it would be fun to buy some cheapo old main and pack it all kinds of screwed up ways and see what happened... ahh well, some day Ill play like that

:P

I love intentional cutaways. I always deploy the main on my belly attached to my tert rings first though so that when I go back into freefall I have a normal container.

I always cutaway a lot higher than that though. Too many things could possibly go wrong for me to want to be possibly chopping that low - even with me having tert rings instead of your 2-minis on one large ring.

In fact, I did 2 jumps on Sunday with a friend who nearly died after he tried to chop on a tertiary rig at 3500 feet, one side couldn't release, spun into the ground because he couldn't get his reserve to inflate which he ended up having to dump into the main.

I always do my intentional cutaways quite high :-) And often, we're doing CRW so someone else can just carry the canopy down for me...

That's my plan.

But I think like all "recently off student status" jumpers, I need to think long and hard about just how dangerous each type of jump is.

(And, obviously, I would not be cutting away at 2,200 feet. :o)

I figure intentional cutaway setups are a good way to get used to flying a canopy backwards. (Some of my friends would say BASE is better, but they're just not well in the heads.)

Always learning...

Laters,

I think it's short for tertiary, meaning "third", as in third parachute you're wearing. I've worn the clip on front mount reserve when doing intentional reserve deployments while TSO'ing a new rig. It's fun to blast out the reserve knowing you don't have to buy beer or pay for the repack. B|

>What's that?

Technically, a tertiary reserve is a third canopy that can be used if your main and 'normal' reserve fail. They are generally chest mounted and are often used during rig TSO testing, when the normal main is planned to be cut away for reserve deployment tests. I use my "tersh" as my first canopy, cut it away and then open my normal main, which is sort of the opposite approach.

>Are these rigs primarily used for intentional cutaway jumps only?

I have heard of small tershes being used by CRW jumpers to provide an extra backup in case of a wrap, but I've seen one used in that way. Tersh containers are also handy to carry bulky stuff on a jump (extra clothes, beer etc)

I've video'd and photographed a few intentional cutaways, but now I can see a practical use for such a rig.

Here's a picture of Aviatrr chopping to check out Relative Workshop's Skyhook system. (dz.eloy '03)

Edit: Another pic, of Hookitt chopping at the Byron Boogie 03. I think it's the same rig. There are two chops on RWS's system on the dz.holiday boogie video.
