IRImplementing rule

ORO.GEN.110Operator responsibilities

(a)The operator is responsible for the operation of the aircraft in accordance with Annex IV to Regulation (EC) No 216/2008, as applicable, the relevant requirements of this Annex and its air operator certificate (AOC) or specialised operation authorisation (SPO authorisation) or declaration.

(b)Every flight shall be conducted in accordance with the provisions of the operations manual.

(c)The operator shall establish and maintain a system for exercising operational control over any flight operated under the terms of its certificate, SPO authorisation or declaration.

(d)The operator shall ensure that its aircraft are equipped and its crews are qualified as required for the area and type of operation.

(e)The operator shall ensure that all personnel assigned to, or directly involved in, ground and flight operations are properly instructed, have demonstrated their abilities in their particular duties and are aware of their responsibilities and the relationship of such duties to the operation as a whole.

(f)The operator shall establish procedures and instructions for the safe operation of each aircraft type, containing ground staff and crew member duties and responsibilities, for all types of operation on the ground and in flight. Those procedures and instructions shall not require crew members to perform any activities during critical phases of flight other than those required for the safe operation of the aircraft. Procedures and instructions for a sterile flight crew compartment shall also be included.

(g)The operator shall ensure that all personnel are made aware that they shall comply with the laws, regulations and procedures of those States in which operations are conducted and that are pertinent to the performance of their duties.

(h)The operator shall establish a checklist for each aircraft type to be used by crew members in all phases of flight under normal, abnormal and emergency conditions in order to ensure that the operating procedures in the operations manual are followed. The design and the usage of checklists shall observe human factors principles and take into account the latest relevant documentation from the design approval holder.

(i)The operator shall specify flight planning procedures to provide for the safe conduct of the flight based on considerations of aircraft performance, other operating limitations and relevant expected conditions on the route to be followed and at the aerodromes or operating sites concerned. These procedures shall be included in the operations manual.

(j)The operator shall establish and maintain dangerous goods training programmes for personnel as required by the technical instructions. Such training programmes shall be commensurate with the responsibilities of personnel. Training programmes of operators performing CAT, whether they transport dangerous goods or not, and of operators conducting operations other than CAT referred to in points (b), (c) and (d) of point ORO.GEN.005 that transport dangerous goods shall be subject to review and approval by the competent authority.

(k)Notwithstanding point (j), operators conducting commercial operations with either of the following aircraft shall ensure that the flight crew has received an appropriate dangerous goods training or briefing, to enable them to recognise undeclared dangerous goods brought on board by passengers or as cargo:

(1)a single-engined propeller-driven aeroplane having an MCTOM of 5 700 kg or less and a MOPSC of 5 or less, operated in a flight taking off and landing at the same aerodrome or operating site, under VFR by day;

(2)an other-than-complex motor-powered helicopter, single-engined, with an MOPSC of 5 or less, operated in a flight taking off and landing at the same aerodrome or operating site, under VFR by day.

PROCEDURES FOR THE RELIEF OF FLIGHT CREW MEMBERS IN CAT OPERATIONS If operating with augmented flight crew, the operator procedures should address all of the following:

(a)the responsibilities and command chain in the flight crew compartment during the absence of the commander;

(b)the assignment of flight crew member stations or seats to relieving crew members, accounting for different phases of flight, including any possible emergency scenarios and controlled rest periods. The operator should consider all possible crew compositions such as multiple captains operating together, instructors during line training, and possible consequences following an incapacitation. The operator should establish the minimum flight level or altitude below which crew members may not vacate their assigned station for the purpose of transferring duties to another crew member; and

(c)any handover and related briefing between flight crew members should cover essential information on command delegation and associated task sharing. The briefing should focus on continuity of the flight. [applicable until 26 March 2028 — ED Decision 2025/002/R]

TURNAROUND COORDINATION

(a)Turnaround coordination refers to the coordination of one or more ground handling activities, which may be performed by one or more providers of ground handling services, during the aircraft turnaround. The goal is to complete the ground handling task(s) efficiently and within a set time frame to ensure the aircraft can depart on schedule.

(b)The operator should establish a turnaround plan for its aircraft and agree with the ground handling organisation on the organisation’s roles and responsibilities during the turnaround to ensure that the organisation coordinates the aircraft turnaround activities in accordance with that plan. [applicable from 27 March 2028 — ED Decision 2025/008/R]

STERILE FLIGHT CREW COMPARTMENT

(a)Establishment of procedures The operator should establish procedures for flight, cabin, and technical crew that emphasise the objectives and importance of the sterile flight crew compartment. These procedures should also emphasise that, during periods of time when the sterile flight deck compartment procedures are applied, cabin crew and technical crew members should call the flight crew or enter the flight crew compartment only in cases related to safety or security matters. In such cases, information should be timely and accurate.

(b)Flight crew activities When sterile flight crew compartment procedures are applied, flight crew members are focused on their essential operational activities without being disturbed by non-safety related matters. Examples of activities that should not be performed are:

(1)radio calls concerning passenger connections, fuel loads, catering, etc.;

(2)non-critical paperwork; and

(3)mass and balance corrections and performance calculations, unless required for safety reasons.

(c)Communication to the flight crew Cabin crew and technical crew use their own discretion to determine whether the situation is related to safety or security matters and whether to call the flight crew. Situations requiring information to the flight crew may include:

(1)any outbreak of fire inside the cabin or in an engine;

(2)a burning smell in the cabin or presence of smoke inside or outside;

(3)fuel or fluid leakage;

(4)exit door unable to be armed or disarmed;

(5)localised extreme cabin temperature changes;

(6)evidence of airframe icing;

(7)cabin/galley equipment or furniture malfunction/breakage posing a hazard to the occupants;

(8)suspicious object;

(9)disruptive passenger;

(10)security threat;

(11)abnormal vibration or noise;

(12)medical emergency;

(13)general drop-down of the oxygen masks in the cabin; and

(14)any other condition deemed relevant by a cabin crew or technical crew member.
