Landed it a bit rough but now it's fun to remember;)



landing with two rounds out should be softer, not rough.

Well, they're not as steerable, they're not as upright, and it's a more dynamic situation with canopies moving around etc.

I used to tell students that they could count on a harder landing if they should get two out. On the other hand, there was no possibility of downplanes.

There is nothing more dangerous than breaking a basic safety rule and getting away with it. It removes fear of the consequences and builds false confidence. (tbrown)

This is probably a stupid question.



Remember, no question at your level is a stupid question. :)
But I don't think you'll ever be jumping 2 rounds like that, but if you do, I have a stupid question for you. :D:D:D



Be safe.

Unless you did this on purpose then it would be fun to remember. Other wise it should of been a wake up call. With as few jumps as you have over two years you might want to rethink jumping that Stilleto 170 before you become a statistic. All skydivers are my friends and we should all look out for one another.

That not on purpose, but such a thing happens time to time with this rig, after you deploy main chute you have to turn off the mechanical ADD unit attached to the reserve, if not... "bum", the whole reserve falls down to a full line stretch an then slowly infiltrates. Such two out landing was a part of training program in russia in old days and a part of fun in our:D. Besides now its fun to remember a lot of things, for example, jump from 500 feet with static line round canopy, that scare :S. my instrucor made it from 350 feet ;)

Look over my old archives and found this photo, interesting, how to name this two out situation B|

Hi Pywas

I think the static line military jumpers still see that 2 out situation once in a while[:/]

Without a AAD:$

>Why is that? Just curious.

Rounds do not "fly" the way squares do. They come straight down. So there's not much the two rounds can do to fight each other; they're both just coming straight down anyway. Many cargo parachute systems use two or more rounds since they tend to not interfere with each other.

Not necessarily. As you can see in the photo, even when they are as much overhead as possible, they bump up against each other. So each canopy is tilted to one side, spilling much of the air it would normally "trap" inside. Thus, the efficiency of each chute is much less than what it would be by itself directy overhead. It could be that each chute is only half as good at arresting descent rate, and thus, even with two chutes out, tilted at angles, the descent rate is similar to just one chute deployed properly.

i don't think it's a final stable configuration, but rather early stage of reserve deployment. what whould be the forces to keep them in that configuration ? would the canopies eventually settle down over head ? the do bump to each other, but the bumps will get sower and slower and everything will be over your head. i know couple of people who had two rounds out and if was very slow descent.

It's the final configuration. The bigger one has forvard speed of 5m/s and drags the reserve which is unsterable. Descent rate is a bit more higher because chutes let more air out because of the angle.



yeah, now i see empty sections on the main opposite the reserve. ok, agree :)

much greater likelihood.... a static line jump, on which the jumper was performing,, a "dummy ripcord pull" i. e. simulation of pulling the MAiN r.c. ( usually just a handle with no cable,,,)...
sometimes the jumper,,, ( remember,, this person may only have 2 or 3 total jumps,, at this stage in the "curriculum"..)inadvertantly pulls...
the reserve ripcord... initiating the reserve depoyment at the same time the static line is opening the main..the picture can't help us to verify if the reserve has a pilot chute or not..... but in that scenario,,, a pilotchuted reserve might have helped to get the canopy out to the side of the jumper,, instead of allowing for the likelihood of the reserve wrapping around the jumper or his mains suspension lines..:o as could be the case without a spring loaded pilot chute...
