B737 crew oxygen on the 737 ng
Hi,
Does any one know what regulation boeing has in mind when they print the table for minimum crew oxygen bottle pressure?
I mean is there a minimum time limit on emergency/100 % oxygen somewhere?
we have a lot of flights over very high terrain and have 22 min oxygen systems on board a few of the 737s but the flight crew oxygen requirments remain the same.
how come?
