Inaddition, when an aeroplane is operated at flightaltitudes at which the atmospheric pressure is lessthan 376 hPa, or which, if operated at flightaltitudes at which the atmospheric pressure ismore than 376 hPa and cannot descend safelywithin four minutes to a flight altitude at which theatmospheric pressure is equal to 620 hPa, thereshall be no less than a 10-minute supply for theoccupants of the passenger compartment.A6-I-6.7.1 An aeroplane intended to be operated at flightaltitudes at which the atmospheric pressure is lessthan 700 hPa in personnel compartments shall beequipped with oxygen storage and dispensingapparatus capable of storing and dispensing theoxygen supplies required in Annex 6 Part IChapter 4.3.8.1.Instructions for completingthe detailed descriptionthe situation observedSAFA Coordination Section Page 89 of 217© European Aviation Safety Agency, 2012 V 2.0
