Which systems should the operator give consideration to when defining the pre-departure check for a non-ETOPS twin-engine operation?

The operator should give consideration, at least, to the following systems: electrical; hydraulic; pneumatic; flight instrumentation, including warning and caution systems; fuel, including potential leakage, fuel drains, fuel boost and fuel transfer; flight control; ice protection; engine start and ignition; propulsion system instruments; engine thrust reversers; navigation and communications, including any route specific long-range navigation and communication equipment; back-up power systems (i.e. emergency generator and auxiliary power unit); air conditioning and pressurisation; cargo fire detection and suppression; propulsion system fire detection and suppression; and emergency equipment (e.g. ELT, hand fire extinguisher, etc.).

Does the pre-departure check for a two-engined aeroplane without ETOPS approval need to include the auxiliary power unit?

Yes, back-up power systems, which include the emergency generator and auxiliary power unit, are listed among the systems to which the operator should give consideration when defining the pre-departure check.

Are engine thrust reversers considered a significant system for the pre-departure check in non-ETOPS twin operations?

Yes, engine thrust reversers are explicitly listed as one of the systems to which the operator should give consideration when defining the pre-departure check.

Which specific fuel-related items should be considered in the pre-departure check for a two-engined aeroplane without ETOPS approval?

The fuel system should be considered, including potential leakage, fuel drains, fuel boost and fuel transfer.

Does the pre-departure check for non-ETOPS operations include cargo fire detection and suppression?

Yes, cargo fire detection and suppression is listed as one of the systems to which the operator should give consideration when defining the pre-departure check.

What is the significance of the propulsion system in the pre-departure check for a two-engined aeroplane without ETOPS approval?

The aeroplane propulsion system is explicitly defined as a significant system to be checked, and its failure could adversely affect the safety of a non-ETOPS diversion flight.

Are emergency equipment items like ELT and hand fire extinguishers part of the pre-departure check for non-ETOPS twin operations?

Yes, emergency equipment, such as ELT and hand fire extinguishers, is listed among the systems to which the operator should give consideration when defining the pre-departure check.

GM1 CAT.OP.MPA.140(d) Maximum distance from an adequate aerodrome for two-engined aeroplanes without an ETOPS approval

Q: What is the purpose of checking significant systems before departure in the context of GM1 CAT.OP.MPA.140(d)?

The purpose is to ensure that the aeroplane propulsion system and any other systems whose failure could adversely affect the safety of a non-ETOPS diversion flight, or whose functioning is important to continued safe flight and landing during an aeroplane diversion, are checked.

Q: Which navigation and communication equipment should be considered in the pre-departure check for a two-engined aeroplane without ETOPS approval?

Navigation and communications, including any route specific long-range navigation and communication equipment, should be considered.
