Page: 180 Chapter: 8 Edition: 3 Operations Manual Part A Revision: 5 Operating Procedures Date: 22 Sep 2020 ii. the possible effects of the malfunctions and iii. the required technical and flight operational measures including additional emergency procedures which might be necessary. j) The final decision to perform the ferry flight rests with the commander. k) The obligation to comply with other aeronautical rules and regulations remains unaffected by the above requirements. 8.7.4.3 Record Keeping and Reporting Ferry flights with impaired airworthiness must be reported to the CAA RM within 10 days. The message must contain the following information: a) aircraft concerned b) aerodromes of departure and destination incl. flight time c) nature of malfunction(s) d) measures taken e) special occurrences during flight. All records which were relevant for the decision must be retained for two years and presented to the CAA RM on request. 8.7.5 POSITIONING FLIGHTS A positioning flight is a flight to position an aircraft to an aerodrome for a subsequent commercial air transport operation. Positioning flights must be performed according to the standard procedures described in the Operations Manual. 8.8 OXYGEN REQUIREMENTS CAT.IDE.A.235, CAT.OP.MPA.285 Supplemental Oxygen requirements for aircraft which are intended to operate at altitudes above 10,000 ft, and which are designed to maintain cabin pressure altitudes below 10,000 ft are as described in the following paragraphs. 8.8.1 FLIGHT CREW Each member of the flight crew on flight deck duty shall have: a) An oxygen mask located within his immediate reach while at his duty station. If the aircraft is operating above 25,000 ft, the mask shall be of the quick donning type; b) In the event of cabin pressure failure, sufficient oxygen for the entire flight time when the cabin pressure altitude exceeds 13000 ft and the entire flight time when the cabin pressure altitude exceeds 10,000 ft but does not exceed 13,000 ft after the first 30 minutes at those altitudes. This is subject to a minimum supply of 2 hours for aircraft certificated to fly at altitudes greater than 25,000 ft; Note: The supply provided must take account of the cabin pressure altitude and descent profile for the routes concerned. The required minimum is the quantity necessary for a constant rate of descent from the aircraft’s maximum certificated operating altitude to 10,000 ft in 10 minutes and followed by 110 minutes at 10,000 ft.

Note: The wearing of beards is only permitted if this will not compromise safety by interfering with the use of the oxygen mask. 8.8.2 CABIN CREW Not applicable to AEROTRANSCARGO’s operation. 8.8.3 OTHER PERSONS ONBOARD (SUPERNUMERARY OXYGEN) CAT.IDE.A.235, CAT.IDE.A.230 The following supplies are to be available to all other persons onboard (Additional Crew Members): a) When operating above 25,000 ft, a dispensing unit attached to an oxygen supply for each person, wherever seated, with 10% more dispensing units and outlets than the number of seats, distributed evenly throughout the Personnel Accommodation area; b) Supply for 100% of the persons carried for the entire flight time when the cabin pressure altitude exceeds 15,000 ft, or for 10 minutes, whichever is the greater; Note: The supply provided must take account of the cabin pressure altitude and descent profile for the routes concerned. The required minimum is the quantity necessary for a constant rate of descent from the aircraft’s maximum certificated operating altitude to 15000 ft in 10 minutes. c) Supply for 30% of the persons onboard for the entire flight time when the cabin pressure altitude exceeds 14,000 ft but does not exceed 15,000 ft; d) Supply for 10% of the persons onboard for the entire flight time when the cabin pressure altitude exceeds 10,000 ft, but does not exceed 14,000 ft after the first 30 minutes at these altitudes; e) If the aircraft is certificated to fly at altitudes exceeding 25,000 ft, and a cabin crew member is required to be carried, a supply of undiluted first aid oxygen for persons onboard who, for physiological reasons, might require oxygen following a cabin depressurisation. The supply should be sufficient for 2% of the persons on board, but not less than that for one person, for the entire flight time at cabin pressure altitudes exceeding 8,000 ft after depressurisation. Note: “Persons onboard” means persons actually carried in addition to the operating crew (Additional Crew Members - see the Operations Manual Part A Section 1). 8.8.4 FIRST AID (THERAPEUTIC) OXYGEN CAT.IDE.A.230 First aid oxygen is intended for those persons onboard who still need to breathe undiluted oxygen when the supplemental oxygen supply has been exhausted. Portable first aid oxygen on board is sufficient for 2% of persons onboard following a pressurization failure when pressure altitude is between 8000 ft and 15000 ft. Further information on the first aid oxygen carried on board is available in the Operations Manual Part B for the relevant aircraft type and in the Operations Manual Part E Section 5.
