High altitude jump woo hoo!
Only 6 more sleeps until I get to do a high altitude 4 way jump with some friends.
For those of you who don’t know what that means… Normally, when you do a skydive, you jump out of the plane at 13500 feet. Or in some cases 10500 feet (if in a smaller plane).
If the plane is between 10000 and 13000 feet for more than 30 minutes, then they have to have oxygen available for the skydivers with a minimum of 1 mask for every 10 jumpers.
If above 13000 feet, everyone needs oxygen for the duration of the flight. (Exceptions are made for the first 500 feet at most DZs)
Above 20000 feet, each skydiver needs oxygen for the descent as well. (An oxygen bottle to jump with)
Now, because of all these regulations, Drop Zones reserve high altitude jumps for special occasions, plan it out months in advance (to be sure to have oxygen available) and take reservations as well.
I’ve been waiting 2 months for this coming Sunday.
Because this Sunday is gonna be my 1st experience with it.
What’s so special about it?
Well, when you jump at 13500 feet, it takes about 1500-2000 feet to stabilize, and an extra 500-1000 feet if you’re in a group to start doing formations. Leaving you about 11000 feet to play with right?
You separate at about 4500 feet and release your canopy at about 3000-3500…
So that leaves only 6500 feet of freefall to “play” in…. Falling at 174 feet per second, that’s only 37 seconds…
When falling from 20000 feet, you still need the 2500 or so feet to stabilize and start formations, plus separation at about 4500 feet, but that still leaves you 13000 feet to have fun with… OR 74 seconds of freefall with which to do your formation… You’re effectively doubling your play time…
Now that’s a LOT of falling =)
It’s costing 85$ plus canopy rental (Unless I can convince a buddy to lend me his :P)
And it’s gonna be 85$ well spent!
I’ll share my experience with you when I get home afterward!
