Momentary Total Mal due to cold weather?

depends on drag, surface area, yadda yadda all that stuff.. if you can get yourself a copy of "Break_Away" you can see Billy Weber pulling on a PC in tow. I doubt there is 70 pounds of force along the line seeing how he could move it pretty good.

actaully that is true, from what the tech guys in R&D told me anyway (we never went to market -- Dow did and it about shut them down)

2:-chop n go silver, I can't think of any type of mal that I wouldn't automatically chop

2 canopies out for one. wraps and collisions also. I would rather think and act than just act. From what I understand you think of plenty of stuff during a 2 second mal/cutaway

Personally, it would depend on the shape of my main riser covers.
Good riser covers - cut away first
Crappy riser covers - do not cut away first

I'm curious as to why that would affect whether or not you'd cut away...?

If I had crappy riser covers, and I cut away from a PC in tow, the risers could release and just flop around above the reserve container. When I open the reserve, the main risers are the perfect shape (a V) to grab onto the reserve PC, or bridle, or freebag, or lines . . .
I believe such a problem led Mick Cottle to the design of the Catapult PC.

"the risers could release and just flop around above the reserve container'
Hmmmmm.....I have no riser covers and even if I did I would still cut away every time. Here's why....I watched a guy with 2,000 jumps cut away not long ago. As my canopy opened up I saw Woody come screaming by. I then saw his D-Bag come out and just as his chute left the bag he cut away and deployed his reserve. I was a little confused as to what happened and why he cut that away. Upon talking to him on the ground he had a P/C hesitation ...P/C in tow.....He went through his decision alti and cut it away. If he hadn't.......He may have very well fired his reserve right into his main with very unpredictable results. I guess the container opened just as he was pulling the cut away handle........Woops...too late....

>every time. Here's why:
I agree that firing a reserve into a deploying main is bad, and might well result in a main-reserve entanglement. However, firing your reserve into trailing risers may give you a reserve PC-in-tow, and of the two, you are more likely to survive a landing with two canopies out than a reserve PC-in-tow with no canopies out at all.
The best case is, of course, to have good riser covers so it's not an issue.

My Buddy on AFF # 7 had a total mal after pulling his main,, later it was decided the closing loop was probably too thick and binded up,, they changed them all after that,,, there all military JM's and said they used ta teach folks to hit the container in case things binded up,, it may have done so in his case,, anyway he pulled silver which knocked out the main,, 2 chutes out,,, jump # 7,, no tangles,, so he cut away the main and landed safely under the reserve,, glad your OK and hope it doesn't happen to me!!

Well, if you happen to run into Mike McGowan ask him -- he was saved by a tree limb from a PC in tow he cut away from. The exact thing that Bill described happened, the main risers caught the slider, pulled it back UP the lines effectively choking the reserve. LIke I said before there are Pros and Cons to each argument -- stay around the sport long enough and you'll see why.
