AMC1 NCO.IDE.A.155 Supplemental oxygen – non-pressurised aeroplanes

ED Decision 2014/016/R

DETERMINATION OF OXYGEN

(a) In the determination of the amount of oxygen for the routes to be flown, it is assumed that the aeroplane will operate at a flight altitude that will allow the flight to be completed safely (i.e. flight altitudes ensuring adequate terrain clearance, navigational accuracy, hazardous weather avoidance, etc.).

(b) The amount of oxygen should be determined on the basis of cabin pressure altitude and flight duration.
