Trust the pros on this one!!
Hey everybody,
Those of us who fly in the AF must complete our chamber ride at least every 5 years. (It used to be 2; not sure why it changed.)
Folks, from someone who just went thru my 4th AF chamber ride a couple of months ago, don't go flying hoping to show someone hypoxia. We did have someone panic in our chamber, and it was only managable because we had the life support professionals there to assist the guy. Had it happened at 25,000 in the RV7A I'm building, I don't know what I would have done. You can't calm a guy down, fly the airplane, and get the mask on his face. Also unlike the chamber and our military jets, you don't have the ability to "gang load" the regulator. That means you put it on 100% O2 and Emergency where it is forcing O2 into the lungs.
My recommendation, call your nearest AF base and find out the phone number to the flying squadron's Life Support shop. It doesn't matter if it is a fighter base, heavy base, or even a missile base with helo support. If there is an aircraft based there, there has to be a Life Support professional on base to maintain the aircraft. Call the Life Support shop, tell them you are a civilian pilot interested in the effects of hypoxia. They should be able to get a video of a chamber ride which you can get a copy of or borrow.
The other item you might ask for is a manual or flyer that talks about the symptoms of hypoxia. The reason AF pilots/airecrew must ride the chamber is so we can identify our specific symptoms of hypoxia (there are many possible symptoms.) For example, mine symptoms are light headedness, followed by my finger tips getting really really cold, followed by tunnel vision and loss of dexterity.
If you are really lucky, you are near a base which has a chamber. They are the experts who can give you all the info you want. You might even be able to swing a ride like the guys who wrote the paper referenced earlier. Here in N. Texas, I know there is one at Sheppard AFB in Wichita Falls, as well as one at Vance AFB in Enid, OK.
Fly safe!
