2 Out with Bigger Reserve.

[r2hubert 0]

Hi I'm currently jumping a Stiletto 120 and I have a Reserve at around 170.
I'm really concern about this difference of size in case of a 2 out situation.
Any inputs or comments are more than welcome.

Thanks.

I have done some 2-out tests and all I can tell you is that it is un-predictable how they will interact. It isn't difficult to avoid 2-out situations and that is where your focus should be. If you do find yourself in a 2-out situation, be very careful, don't make the situation worse.

Just curious when you do tests for two out do you have a front mount so you can cut both away should need be thanks.

Yes, I did. I used the chest mount as one of the canopies in the 2-out. I only ended up cuting away the main and chest mount and going to the actual reserve once.

Buy a smaller reserve.


Buy a bigger main.


Or a little of each.

I wouldn't think that's a great idea. The chances of needing your reserve to put you down gently are a lot more likely than having 2 out and the size difference causing a problem.

Good point. Read the second line for an alternative solution.

Oh, the third line also has a some potential.

I like to have a reserve about double the size of my main, and just stay the hell out of the basement.

I chopped my 99 main and was under a 218 reserve above 2 grand this summer.

I don't size my equipment on the basis of personal CRW.

Your main and reserve should be sized to give acceptable landings in all conditions you intend to use them.

If you dump at a reasonable altitude (reasonable minus some is enough to keep you from sniveling through Cypres firing altitude when you open lower ) and use your reserve when low (1800 feet might be a nice number) you won't have a two canopy out situation.

If that does happen, canopy sizing won't guarantee or preclude problems. I've seen a Stiletto 120 and Tempo 150 flying in a nice stable side-by-side; and more similarly sized canopies in a down plane and chopped.

Assuming everything is perfect, you can load a modern main canopy much more heavily than a reserve before landings are compromised (ease of getting a good landing, ultimate stall speed, etc). In an asphalt parking lot I'd really rather land a cross-baced tricell @ 2 pounds/square foot or other modern elliptical @ 1.8 than a reserve loaded beyond 1.5.

With all of the likely "what-ifs" I want an even bigger reserve.

If you bought a CYPRES because it will save you if you get knocked out, you ought to size your reserve to provide a surviveable landing with the brakes stowed and no flare. This is a lot bigger than what I'd want to skydive while conscious.

If you bought a reserve because your main might malfunction after which you'll cut away and be under canopy lower than usual thus resulting in limited landing options, you might want a bigger reserve.

If you aren't jumping similar sized F111 seven cells in both containers, you'll be a lot less current under the reserve and might want something bigger.

I usually jump a Samurai 105 (and will go smaller) and PD143 (will stick with it - bigger reserves just give you more options).

Although Sun Path and Relative Workshop don't build rigs compatable with this philosophy, the Mirage, Racer, and Wings are all available in reasonable size combinations for those of us who want smaller mains.
