16000ft jump

Recommended Posts

We're going to be jumping from 16000ft AGL which will put us at aprrox 20000+ ft MSL this weekend. The letter I got said that O2 will be required on the plane and I know the requirements from the SIMS about useing O2 so my question is (since I have never jumped that high ) when you get into the plane do you wear the O2 all the way up or can you wait till you reach the max alt and then put it on? What have you all done

According to the FAR's, passengers only have to be supplied supplemental oxygen at altitudes above 15,000 ft. MSL, so I would assume that you wont need to use it until you get up that way, although I personally would start using it a little sooner than that...Hope that helps.

There should be a briefing before the loading takes place. We normally start putting it on around 10 MSL. You need to be on it by 15 MSL. The key is to not use a lot of energy up high. Lots of movement or energy output burns a lot of O2 in your body, just relax and enjoy the ride.

Depends on the organizer, type of dive, climbing speed of plane, etc. Generally you don't go on it below 10K, definitely above 15K. Also note that you don't need it blowing hard in your face, in your nose, or in your mouth - if you feel anything at all coming out of the tube, you're generally OK. FAA recommends 1.6 liters per minute at 16,000 feet, and that's a very small amount of oxygen. I usually cut the end off the tube, stick the end in my mouth, and breathe through my nose. That way I can put my helmet on with the tube there, and pull the tube out at the last minute.
One of my pet peeves are the oxygen hogs on high altitude loads - if it's not puffing their cheeks out or blowing up their nose, they start yelling "turn it up! turn it up! I can't feel anything!" Which results in higher flow rates, and aborted jumps when one plane runs out of O2 just before jump run. On a big way that can cost you upwards of $2000.

Yep....put it on about 10K. Thats the generally recognized alti where the oxygen content starts to get low. Of course the effects are differen't for everyone. Do yourself a favor. Don't shave, use cologne, or have anything else on your face that may be petroleum based. Wash with soap the night before and don't put anything else on.There is a small chance of fire if you are using 100% O2 if it reacts with shaving creams or colognes. Have fun....be safe. Get someone to explain some of the symptoms of hypoxia to you. If you are in the plane and get unusually giddy. You may have a problem....:)"There once was a man named Enis.....B|"-Krusty the Clown

I love you bein a woman too. I do love women.....such intriguing creatures. I just hate the ones that abuse that fact. Get all hugely fat and disgusting but have a cute face. That always makes me mad because I think what a hottie they would be if there was less of them. I'm not a weight Nazi but if your ass has to be buttered to fit out the Otter Door, PUT DOWN THE FORK! and slowly back away!
