34、to supply the entire crew for the total duration of any specified design mission The oxygen supply system shaTl be sized to ensure mission completion in the event of loss of cabin pressure enroute to or at the combat zone. If applicable, the oxygen system shall be sized to include range extension du

35、e to auxiliary fuel stores and/or aerial refueling. 3.3.1.2 Bomber aircraft supply. Bomber aircraft shall have an oxygen system of sufficient capacity to supply breathing oxygen to the entire crew for 75 percent of the duration of the longest specified design mission, or to the entire crew for the t

36、otal time the cabin altitude is above 10,000 feet (3048 metres), whichever condition establishes the largest amount. The oxygen supply system shall be sized to ensure mission completion in the event of loss of cabin pressure enroute to or at the target. If applicable, the oxygen system shall be size

37、d to include range extension due to auxiliary fuel stores and/or aerial refueling. 3.3.1.3 Transport aircraft supply. Transport aircraft shall have an oxygen system of sufficient capacity to supply all the primary crew members and al 1 of the passengers with breathing oxygen whenever the cabin al ti

38、 tude exceeds 10,000 feet (3048 metres). In the event of loss of cabin pressure, the oxygen system shall provide the full primary aircrew with breathing oxygen for at least 50 percent of the design mission duration. The passenger oxygen supply shall be dispensed from a continuous flow system and sha

39、ll have sufficient capacity to provide breathing oxygen to a full passenger load for 50 percent of the design mission duration or for a shorter period if so specified by the acquiring activity, but in no case for less than 15 minutes. 5 Provided by IHSNot for ResaleNo reproduction or networking perm

40、itted without license from IHS-,-,-MI L-D-8683C When therapeutic oxygen capability is specified, a supplemental quantity shall be included within the passenger oxygen supply. Therapeutic oxygen usage shall be independent from passenger oxygen usage and the quantity shall be adequate for 100 percent

41、of the design mission duration plus two hours to allow for patlent loading and unloading. * 3.3.1.4 Mission specialist and training aircraft supply. Mission specialist and training aircraft shall have an oxygen system of sufficient capacity to supply the entire flight crew, mission specialist traine

42、es, and any passengers (if appl icable) with breathing oxygen whenever the cabin altitude exceeds 10,000 feet (3048 metres). The flight crew may need additional oxygen supply for flight above 35,000 feet (10,668 metres), inflight refueling, and night flight. The oxygen system shall support all aircr

43、aft occupants during depressurization at cabin al ti tudes and durations as specified by the acquisition activity. 3.3.2 High altitude aircraft supply. Aircraft having a sustained flight capability above 50,000 feet (15,240 metres), or the requirement to remain above 42,000 (12,801 metres) for a per

In addition, provisions shall be made for the use of preisure breathing masks during flight operations at lower al ti tudes r 3.3.3 Systems utilizing

46、capsules. The pressurization requirements and the oxygen requirements shall be as specified in MIL-C-25969 or MIL-A-23121, as applicable. The system to be installed shall be capable of meeting the specified mission profile. 3.3.4 Portable oxygen systems. When crew mobility within the aircraft is req

47、uired, as is normally the case in bomber and cargo aircraft, portable oxygen systems shall be provided in a ratio not less than one system for two crew- members.
