S.O.S. and RSL what is the problems?

[7. What is the appropriate action if below 1,000 feet without a landable parachute?

Immediately deploy the reserve parachute, but not below 1,000 feet with an SOS system.]

Why not with a SOS what is the reasoning for that? B/C it chops main, and you are looking for as much canopy(s) above you?

[27. What is generally the best action to take in the following two-canopy-out scenarios ?

a. Biplane

Release the brakes on the dominant canopy only and steer that canopy gently; PLF.

b. Side by side

Release the brakes on the dominant canopy only and steer that canopy gently; or release the RSL (if time) and cut away; PLF.

c. Downplane

Release the RSL (if time) and cut away.]

Why release RSL? If the reserve is already out the RSL guide ring will just slide off the reserve cable on it's way out? OR are we worried about the reserve deployment cable being in a bind or trapped and the rsl not being able to slide off the cable leaving the rsl side riser still attached when you cut away?

>Why not with a SOS what is the reasoning for that? B/C it chops main . . .

Yes.

>Why release RSL?

Because the RSL hanging off the main risers is another snag point; you don't want lots of snag points if your main has to slide past your reserve as it leaves.

x4 that is what I was thinking just making sure I was not trying to read too far into it. I like the idea of SOS deploying with one handle, but I think I like the option of being able to cut away, and wait to clear anything before deploying reserve. I like the dual with RSL, gives you the option to unhook RSL and clear, or with RSL it is pretty much a SOS. Am I correct.

My current rig is SOS with RSL. So there is 2 pieces of EQ. pulling reserve right. (SOS handle, and riser RSL).

>or with RSL it is pretty much a SOS. Am I correct.

Not really. An RSL will NOT deploy your reserve even if you pull your cutaway handle if:

-you have not deployed your main yet
-you have a total
-you have a PC in tow
-you have a very low drag mal, older (reverse) risers and tight riser covers.

{{ The two above is b/c of lack of enough drag to pull RSL out of velcro and pull reserve cable?}}

Not really. In a PC-in-tow there is never any pressure on the risers; the container is still closed. In a low drag mal with reverse risers, there may not be enough pressure to pull open the riser covers and allow the reverse risers enough room to release. (They will not release if pressed against the harness.)

When I was doing some promo work with a large costume on this happened to me. I ended up very lucky, because of the costume I had to do everything by feel, with some large gloves on. Even after the reserve deployed, I had to undo the three rings by hand because of the angles.

Bonus questions for cvfd1399:
* What are some things you could do to help reduce the likelihood of finding yourself below 1,000 feet without a landable parachute? How often would you do each of these things?

* In the event you found yourself below 1,000 feet without a landable parachute, and you had an SOS system, what would you do?

Pull.

Well inspection/maintenance on the ground. Handle checks in the plane to lower the risk of having a mal at the door/in air. Gear check! ALTITUDE awareness! If tracking or FFing slow down before dumping to keep from possibly blowing out your canopy. Pull on time/stable and do thorough canopy control check above hard deck(2,500 for me). Head on a swivel to keep from having a canopy collision. All every jump.

Kill myself for sure not landable parachute... go for reserve b/c it's better to know your going in and to have tried, than to have a freshly packed reserve on your back when they cut the rig off you and never know if it would have deployed in time. Injury type not landable.... plf the hell out of it. It is hard to say what anyone "will" do when the time arrives, but I think this is what I would most likley do.

In a perfect would I could say look at your SOS handle and pull the reserve cable that is swagged to the handle by hand without taking it out of the pouch, but at 1k and 3 or more cables on the handle your not likley to choose the right one, and pull it with one finger in time. This might give you a good canopy, and a bad one or 2 bad ones, but I figure the more drag the better.

Other than my perfect world scenario was I right on the rest?

Good luck pulling on that little metal ball hard enough to open your reserve. Try it next ime you need a repack. I bet you'll need a pair of pliers.(Might be a good thing to carry next to the hook knife. Hmmmm.)

I used to own a rig for AFF that had a small pillow handle where the ball was swaged on the SOS handle. Grab that alone and you could pull the reserve without cutting away. It was an Australian rig, Pigmee, I think, but it's been a few years.

How much altitude does it take to cut away and open a reserve? I'd say 300 feet or less, although I'd hate to do it that low. i'd definitely chop at 700 feet or higher to save my life, but my eyes would really be bugging out looking at the ground coming up. Seen people do it lower than that. I can understand the nature of your question, just don't get too locked into "1000 feet." Yes, I think avoidance of the situation is the best thing.

Single Operation System, where just one handle both releases the main parachute and opens the reserve, hopefully in that order. it's very common setup for students, and works quite well, but it does have a disadvantage or two.

Pretty much everything I had thought about.

On the SOS systems I used as a student, we had pretty long reserve cables. I reckoned I could wrap it around my finger and give it a yank, worst-case. I can't guarantee it would come out - hard reserve pulls happen, and you'd be at a disadvantage - but I'd be willing to give it a try and a broken finger in the air if I thought my life probably depended on it. (And I wear gloves specifically to enhance my effective hand strength and protection, even in summer.)

I'll see about trying it on one of the student rigs at repack time.

Cool. If I'm ever a one-armed jumper, I'll look into that.

Thanks, John. I'll do a search for more info.
