The Civil Aviation (Operation of Aircraft - HelicopterOperations) Regulations, 2024

1.3. To minimise the probability of in-flight engine failure, the engine shall be equipped with: (a) for turbine engines: a re-ignition system that activates automatically or a manually selectable continuous ignition system unless the engine certification has determined that such a system is not required, taking into consideration the likely environmental conditions in which the engine is to be operated; (b) a magnetic particle detection or equivalent system that monitors the engine, accessories gearbox, and reduction gearbox, and which includes a flight deck caution indication; and (c) a means that would permit continuing operation of the engine through a sufficient power range to safely complete the flight in the event of any reasonably probable failure of the fuel control unit. 81 Civil Aviation (Operation of Aircraft-Helicopter Operations) GN. NO.3 (Contd.)

2.1. Helicopters operating in performance Class 3 in IMC shall be equipped with the following systems and equipment intended to ensure continued safe flight or to assist in achieving a safe forced landing after an engine failure, under all allowable operating conditions: (a) either two separate electrical generating systems, each one capable of supplying all probable combinations of continuous in-flight electrical loads for instruments, equipment and systems required in IMC; or a primary electrical source and a standby battery or other alternate source of electric power that is capable of supplying 150 per cent of electrical loads of all required instruments and equipment necessary for safe emergency operations of the helicopter for at least one hour; and (b) an emergency electrical supply system of sufficient capacity and endurance, following loss of all normally generated power to, as a minimum: Note.- If a battery is used to satisfy the requirement for a second power source (see 2.a) above), an additional electrical power supply may not be required. (i) maintain the operation of all essential flight instruments, communication and navigation systems during a descent from the maximum certificated altitude in an autorotational configuration to the completion of a landing; (ii) maintain the operation of the stabilization system, if applicable; (iii) (iv) where required, provide power to one pitot heater, which shall serve an airspeed lower the landing gear, if applicable; indicator clearly visible to the pilot; provide for the operation of the landing light; (v) (vi) provide for one engine restart, if applicable; and (vii) provide for the operation of the radio altimeter; (c) a radio altimeter; (d) an autopilot if intended as a substitute for a second pilot. In these cases, the Authority shall ensure the operator’s approval clearly states any conditions or limitations on its use; (e) a means to provide for at least one attempt at engine re-start; (f) an area navigation system approved for use in IFR, capable of being used to locate suitable landing areas in the event of an emergency; (g) a landing light that is independent of retractable landing gear and is capable of adequately illuminating the touchdown area in a night forced landing; and (h) an engine fire warning system.

3.0 MINIMUM SERVICEABILITY REQUIREMENTS - OPERATING EQUIPMENT The Authority shall specify the minimum serviceability requirements in accordance with Civil Aviation (Instruments and Equipment) and (Airworthiness) Regulations for operating equipment in helicopters operating in performance Class 3 in IMC.

4.0 OPERATIONS MANUAL INFORMATION The operations manual shall include limitations, procedures, approval status and other information relevant to operations in performance Class 3 in IMC, in accordance with Civil Aviation (Air Operator Certification and Administration) Regulation. 82 Civil Aviation (Operation of Aircraft-Helicopter Operations) GN. NO.3 (Contd.)

5.2. The operator approved to conduct operations by helicopters in performance Class 3 in IMC shall report all significant failures, malfunctions or defects to the Authority who in turn shall notify the State of design in accordance with Civil Aviation (Airworthiness) and (Safety Management) Regulations. The Authority shall monitor operations in performance Class 3 in IMC so as to be able to take any actions necessary to ensure that the intended safety level is maintained. The Authority shall notify major events or trends of particular concern to the appropriate type certificate holder and the State of design.

6.1. Operator route planning shall take account of all relevant information in the assessment of intended routes or areas of operations, including the following: (a) the nature of the terrain to be overflown, including the potential for carrying out a safe forced landing in the event of an engine failure or major malfunction; (b) weather information, including seasonal and other adverse meteorological influences that may affect the flight; and (c) other criteria and limitations as specified by the Authority.

7.0 FLIGHT CREW EXPERIENCE, TRAINING AND CHECKING

7.2. The Authority shall prescribe the minimum flight crew experience for helicopters operating in performance Class 3 in IMC. The operator’s flight crew training and checking programme shall be appropriate to operations in performance Class 3 in IMC, covering normal, abnormal and emergency procedures and, in particular, detection of engine failure including descent to a forced landing in IMC and, for single engine helicopters, entry into a stabilised autorotation.

8.0 OPERATOR CERTIFICATION OR VALIDATION The operator shall demonstrate the ability to conduct operations in performance Class 3 in IMC through a certification and approval process specified by the Authority in accordance with Civil Aviation (Air Operator Certificate and Administration) Regulations.
