This supplement establishes CAA in terpretations and policies on providing oxygen for, and administering oxygen to, crew members and passengers in pres surized and nonpressurized cabin air craft at various operating altitudes.
The following policies and interpreta tions are hereby adopted:
41.24-1 .Supplemental oxygen for crew members .CAA interpretations which apply to 41.24 a 1 . The phrase, during the portion of flight in excess of 30 minutes within this range of altitudes applies to all crew members including the flight crew members on flight deck duty. Thus, oxygen is re quired to be provided for, and used by, each member of the flight crew on flight deck duty only during the portion of the flight in excess of 30 minutes within this range of altitudes.
41.24-2 Oxygen requirements for stand-by crew members CAA interpre tations which apply to %41.24 a .
Stand-by crew members who are on call or are definitely going to have flight deck duty prior to the completion of a flight must be provided with the same amount of supplemental oxygen as that provided for crew members on duty other than on flight deck duty. However, if the stand by crew members are not on call and will not be on flight deck duty during the remainder of the flight, they must be considered as passengers with regard to supplemental oxygen.
41.24-3 Operating instructions CAA
Policies which apply to 41.24. Operat ing instructions appropriate to the type of system and masks installed should be Provided for the flight crew in the ap propriate air carrier manual. These operating instructions should contain a graph or a table which will show the
duration of the oxygen supply for the various bottle pressures and pressure al titudes.
41.24-4 Oxygen requirements for jum p seat occupant CAA policies which apply to 41.24. When the jump seat is occupied by a check pilot, a crew mem ber, or a flight crew member, as defined by 41.137 h , j and i respectively, oxygen should be provided in accordance with the requirements of 41.24. The provision of oxygen at the jump seat lo cation may be accomplished either by a portable oxygen unit or an outlet in a fixed system.
41.24-5 Oxygen requirements for in fants-in-arms CAA policies which ap ply to 41.24 b . Provisions should be made for administering oxygen to in fants-in-arms and additional oxygen should be carried whenever an unusually large number of infants is carried. This additional oxygen is needed only when there is a passenger or infant for each seat position and the number of infants not provided for exceeds 50 percent of the seat positions. Acceptable methods of administering the oxygen to infants and now used by many operators are:
a A disposable plastic mask which can be fitted to the face; b an infant size BLB oronasal mask and c semi-rigid paper cups, specifically reserved for the purpose, which can be fitted over the in fants nose and mouth, with a hole punched through the bottom through which an oxygen tube or a Y-connector can be inserted. Any other acceptable method may also be used.
41.24r-6 Oxygen requirements for clinical purposes CAA policies which apply to 41.24 b . The regulation do not require that oxygen be provided for clinical purposes; hence, if the air carrier believes that such oxygen is to be desired, he should provide oxygen for this purpose. It is suggested that port able units of any size the air carrier desires be used for this purpose in order that the minimum supply required for supplementary breathing purposes will be preserved. If, however, the operator wishes to use a common source of supply fo r the oxygen required by the regula tions and for clinical purposes, he may Continued on next page
