Curious...What's your highest elevation?

Recommended Posts

Doesn't mild hypoxia start at around 5-8k or so, then gets worse as you go up? Bad night vision first, then coord, judgement, etc?
If you do 12-15k regularly, do you use O2 on the way up?
I'm curious because I've only jumped from small cesnas that hardly ever went above 9k.
It just seems to me that if you were out drinking the night before, a 12k jump without O2 on the way up might mean being at less than peek performance.
This is one area I don't know much about. You hear about mal this, canopy that, reserve this, but nada on hypoxia.

22,000 with o2
18,000 without
a person could get hypoxia frome 10,000 if you're up there too long.
12-13k on an otter without being on hold at altitude too long shouldn't affect you too much.
Some good articles in past "Parachutist" that help explain what's up.

My home DZ regularly takes jumpers to 13.5, 15 if the pilot is in a good mood or gets to see some skin, and even occasionally 16. I think that 13.5 is not uncommon at any DZ equipped with a turbine aircraft, or two, or three...
This is all without O2.

Like four jump runs at 12,500 before finally exiting? Funny, that happened to me this weekend... ;)
Highest I've jumped from is 14999... there was no oxygen on board so I can't legally tell you what the actually altitude was...

two loads in a row, the 1st one went to 17,500 and the second one went to 17,000. I had a bloody nose on the second load when we were on jump run. I thought that the guy next to me was trying to say I had snot on my nose:D It ended up being the coolest 2-way sit/stand fly I've ever done and my face didn't get too bloody during freefall.

Naw....we always go to at least 13,000ft here in Florida.. My home DZ always goes to at least 15,000ft.. No O2 necessary for most people - except maybe those severely out of shape or heavy smokers.. If you're up there for very long, then it can become a problem..
Highest I've been with O2, 22,500ft......Highest without O2.....15,000ft.....really...seriously...honest, only 15,000, since above that would be illegal.. ;)

The highest load I did was from 18,000 out of an F27. The plane wasn't usually a jump plane, so they were pressurizing and depressurizing the cabin instead of using O2. Unfortuntely on all 3 loads, (without going into detail) they did this wrong and everyone ended up hypoxic. But the freefall was SWEET!

I'll second that... I was on load 2, and landed out, along with some of the other 44 people on that one... I think it was about 18,000 MSL and about 17,000 AGL... it was fun - a little bit crazy, but fun.

15K from our King air ... with regards to the rules & reglatations on drinking at the dz.. when the last load is down and the beer light is on.. start unpacking the cases that you should already have stored in your car, becuase starting AFF you will be suppling a lot of them!! Its allll good!!

Standard is about 3500 to 4000 meter Ground. We're going to do a 10'000m Ground in August/September with O2. It's gonna be a scream. Can hardly wait for it to happen. Have to do a pressure chamber check in may.
I'll be posting about it as soon as it took place.
