(3) in no case less than 10 minutes' oxygen supply for all passengers carried; and
(4) when a cabin crew member is required to be carried, therapeutic oxygen capable of
providing not less than 45 minutes supply for 10 % of the passengers carried; and
(5) the extra oxygen units shall be uniformly distributed throughout the aircraft; and
(6) oxygen masks shall be automatically presented to the passengers and crew members
in the passenger compartment when the cabin pressure altitude exceeds 14,000 feet;
and
(7) flight crew shall be provided with a manual means of making the passenger masks
available in the event of failure of the automatic system.

OTAR.135.750 Flight recorders – construction and installation
(i.e Any type of recorder installed in the aircraft for the purpose of complementing
accident/incidentinvestigation).
Note 1: Crash-Protected flight recorders comprise one or more of the following systems:

a flight data recorder (FDR),
- a cockpit voice recorder (CVR),
- an airborne image recorder (AIR),
- a data link recorder (DLR).
Note 2: Lightweight flight recorders comprise one or more of the following systems:
- an aircraft data recording system (ADRS),
- a cockpit audio recording system (CARS),
- an airborne image recording system (AIRS),
- a data link recording system (DLRS).
(a) The operator shall ensure that any required flight recorder:
(1) is constructed, located and installed so as to provide maximum practical protection for
the recordings in order that the recorded information may be preserved, recovered and
transcribed; and
(2) meets the prescribed crashworthiness and fire protection specifications.
(3) Non-deployable crash-protected flight recorder containers shall have securely attached
an automatically activated underwater locating device operating at a frequency of 37.5
kHz. This device shall operate for a minimum of 90 days.

OTAR.135.755 Flight recorders – flight data recorder (FDR) and alternatives
Note 1: For aeroplanes for which the application for type certification is submitted before 1
January 2016, specifications applicable to crash-protected flight recorders may be found in
EUROCAE ED-112, ED-56A, ED-55, Minimum Operational Performance Specifications
(MOPS), or earlier equivalent documents.
Note 2: For aeroplanes for which the application for type certification is submitted on or after 1
January 2016, specifications applicable to flight recorders may be found in EUROCAE ED-112A,
Minimum Operational Performance Specifications (MOPS), or equivalent documents.
Note 3: Specifications applicable to lightweight flight recorders may be found in EUROCAE ED-
155, Minimum Operational Performance Specification (MOPS), or equivalent documents.
Note 4: Parameters to be recorded are listed in Table A8-1 and A8-3 of Appendix 8 to ICAO
Annex 6 Part I (for aeroplanes), and Table A5-1 and A5-3 of Appendix 5 to Annex 6 Part III (for
helicopters).
(a) Where an aircraft is required to be equipped with flight recorder systems, the requirements may
be met singly or in combination, as follows:
(1) A multi-engined turbine-powered aeroplane with MTOM of 5,700 kg or less, required to
be equipped with a FDR and/or a CVR, may alternatively be equipped with one
combination recorder (FDR/CVR).
(2) Combination recorders (FDR/CVR) may be used to meet the flight recorder equipage
requirements for helicopters.
(b) A turbine-engined aeroplane with MTOM of 5,700 kg or less for which the first certificate of
airworthiness for that individual aeroplane, was issued on or after 1 January 2016 shall be
equipped with:
(1) a Type II FDR; or
(2) a Class C AIR or AIRS capable of recording flight path and speed parameters
displayed to the pilot(s); or
(3) an ADRS capable of recording the essential parameters. (See Note 4 above,
regarding the parameters to be recorded.)
(c) An aeroplane which is required to record normal acceleration, lateral acceleration and
longitudinal acceleration for which the application for type certification is submitted to an ICAO
Contracting State on or after 1 January 2016 and which is required to be fitted with an FDR shall
record those parameters at a maximum sampling and recording interval of 0.0625 seconds.
(d) An aeroplane which is required to record pilot input and/or control surface position of primary
controls (pitch, roll, yaw) for which the application for type certification is submitted to an ICAO
Contracting State on or after 1 January 2016 and which is required to be fitted with an FDR shall
