Oxygen bottles duration & MBU-12/P mask?

[An-2]

I was wondering about the probable duration of the two 1800 PSI oxygen bottles of a OV-1D Mohawk. Would you have a duration chart?

Any lead to get two new MBU-12/P at a decent price?

Cheers.

Phil, I don't think you can get new reasonable. But you can usually get some fairly new ones for a reasonable price on Ebay.

If you are talking about the Bailout Bottles at 1800 PSI, they last approximately 10 minutes, they can last a little bit longer or go quicker. We teach our aircrews that they last 10 minutes, bottom line.

Negative Mike, I'm talking about the main oxygen bottles on board.

Digging in this gold mine, I found what I was looking for (Oxygen duration tables): www.tpub.com/content/aviationmaintandmisc/TM-55-1510-215-10/TM-55-1510-215-100064.htm

RickH: thanks for the link, flighthelmet.com is indeed offering MBU-12/P's at a cheaper price than Gentex direct.
