Absolute pressure	Metres	Feet
700 hPa	3 000	10 000
620 hPa	4 000	13 000

(2)A flight to be operated at altitudes at which the atmospheric pressure in personnel compartments is less than 700 hPa shall not be commenced unless sufficient stored breathing oxygen is carried to supply—

(a)all crew members and 10 per cent of the passengers for any period in excess of 30 minutes that the pressure in compartments occupied by them is between 700 hPa and 620 hPa;

(b)the crew and passengers for any period that the atmospheric pressure in compartments occupied by them is less than 620 hPa.

(3)A flight to be operated with a pressurized helicopter shall not be commenced unless a sufficient quantity of stored breathing oxygen is carried to supply all the crew members and a proportion of the passengers, as is appropriate to the circumstances of the flight being undertaken, in the event of loss of pressurization, for any period that the atmospheric pressure in any compartment occupied by them would be less than 700 hPa.
