(b) for passengers--

(i) for flights at altitudes above 10,000 feet but not above 30,000 feet--

a supply of oxygen for continuous use by 10% of the passengers for a period of 30 minutes, and also for the whole time (if any) in excess of 30 minutes following failure of the pressurisation system, during which the pressure in any compartment occupied by them would be below 700 millibars and in addition, if the aircraft is not capable at all points along the route to be flown, without exceeding operational limitations or infringing terrain clearance requirements, of descending from its cruising altitude to below an altitude of 15,000 feet within 6 minutes, and of remaining below that altitude thereafter, a supply of oxygen for continuous use by all the passengers for the whole time during which the pressure in any compartment occupied by them would be below 570 millibars;

(ii) for flights at altitudes above 30,000 feet but not above 35,000 feet--

a supply of oxygen for continuous use by 15% of the passengers for a period of 30 minutes and also for the whole time (if any) in excess of 30 minutes, following failure of the pressurisation system, during which the pressure in any compartment occupied by them would be below 700 millibars and in addition a supply of oxygen for continuous use by all the passengers for the whole time during which the pressure in any compartment occupied by them would be below 570 millibars; also a supply of oxygen in a portable container sufficient for the simultaneous first-aid treatment of two passengers.

Note 1--For the purpose of the calculation of the amount of oxygen to be provided for use following failure of the pressurisation system, it is to be assumed that the failure will take place at that altitude and stage of the flight which would impose the most exacting requirement for oxygen, and that after failure the aircraft will descend immediately and in accordance with the emergency procedure specified in the aircraft's flight manual, to a safe altitude, and thereafter fly at an appropriate altitude to enable it to reach its declared destination or the nearest point at which a safe landing may be made. Following such a failure the pressure in the crew and passenger compartments is to be considered to be the same as that obtaining at the relevant flight altitude. Calculation of the oxygen requirements is to take into account the time necessary for the descent and recovery phases of the emergency and the time spent at any altitude requiring the use of oxygen on the final stage of the flight prior to landing.

Note 2--For the purposes of this paragraph and of Clause (II) of subparagraph (i) of paragraph (2) of Article 8 of this Order, the expression "failure of the pressurisation system" means inability through any cause to maintain an atmospheric pressure of at least 700 millibars in any occupied compartment.

Note 3--Approximate altitudes in the Standard Atmosphere corresponding to the values of absolute pressure used in this paragraph and in Note 2 thereto and also in paragragh (3) of Article 34 of this Order are as follows:--

Absolute Pressure	Feet	Metres
700 millibars	10,000	3,000
570 "	15,000	4,600
376 "	25,000	7,600

(9) For all flights for which the carriage of stored oxygen is required by this Order--

(a) suitable means of storing, supplying and dispensing oxygen;

(b) suitable means of indicating to the passengers in each compartment the appropriate times at which oxygen should be used and the method of use.

(10) For flights on which pressurised aircraft are intended to be operated at altitudes at which the atmospheric pressure is less than 376 millibars--a device to provide warning of any dangerous loss of pressurisation.

(11) For flights on which a licensed flight navigator is required to be carried in the aircraft--

(a) adequate facilities for the taking of astronomical observations, including observations for checking the magnetic compass;

(b) chart tables;

(12) On flights when the weather reports or forecasts available at the aerodrome at the time of departure indicate that conditions favouring ice formation are likely to be met--

means or equipment to prevent any impairment through ice formation of the functioning of the controls, means of propulsion, lifting surfaces, windows or equipment of the aircraft which would endanger the safety of the aircraft.

5. Gliders.

(1) For all flights--

(a) such instruments, equipment and devices as the Minister may, at his discretion, require to be carried in the particular glider;

(b) safety harness for every seat in use.
