Frequently Asked Questions

EDTO (Extended Diversion Time Operations) replaced the legacy term ETOPS (Extended-range Twin-engine Operational Performance Standards) following ICAO Amendment 36 to Annex 6 in 2019. While ETOPS applied only to twin-engine aeroplanes, EDTO applies to all aeroplanes operating beyond a threshold distance from an adequate aerodrome, regardless of the number of engines. This course covers both terminologies since many manufacturer documents and existing operator procedures still reference ETOPS.

OPS.SPA refers to Subpart SPA (Special Approvals) of EU Regulation 965/2012 on air operations. It defines additional requirements that operators must meet for specific operation types including EDTO, RVSM (Reduced Vertical Separation Minima), and operations in NAT HLA (North Atlantic High Level Airspace). These special approvals have direct implications for CAMOs and AMOs regarding continuing airworthiness management, maintenance programme content, and equipment serviceability requirements.

EDTO Significant Systems are those aircraft systems whose failure or degradation could adversely affect the safety of an EDTO flight, or whose continued functioning is specifically important during a diversion. These typically include propulsion systems, electrical power generation, hydraulics, pneumatics, fuel and fuel control systems, fire protection, and communication/navigation systems. CAMOs must identify, track, and manage the reliability of these systems as part of the EDTO continuing airworthiness programme. This course covers identification, categorisation, and reliability monitoring in detail.

The CAMO plays a central role in EDTO operations by managing continuing airworthiness elements including the Aircraft Maintenance Programme with EDTO-specific tasks, EDTO significant systems reliability tracking, dual maintenance limitations, EDTO pre-departure checks, verification programmes, parts and configuration control, and propulsion system monitoring. The CAMO must also establish EDTO procedures in the CAME, ensure adequate maintenance contracts with Part-145 organisations cover EDTO requirements, and maintain control of each aircraft’s EDTO status. This training covers all nine continuing airworthiness elements from ICAO Doc 10085 Chapter 4.

NPA 2025-12 is an EASA Notice of Proposed Amendment that introduces a new Appendix VI to AMC to Part-CAMO specifically addressing EDTO considerations. It proposes to move EDTO continuing airworthiness provisions from the legacy AMC 20-6B into the AMC framework of EU 1321/2014, aligning with the latest revision of ICAO Annex 6. The NPA also introduces specific EDTO training and qualification requirements for CAMO and Part-145 personnel. This course covers the proposed amendments and helps organisations prepare for their implementation.

A CMP (Configuration, Maintenance, and Procedures) document is referenced in the aircraft Type Certificate Data Sheet (TCDS) and specifies the minimum required configuration, maintenance actions, and dispatch standards that must be complied with before commencing EDTO operations. It typically contains the particular airframe-engine combination configuration requirements, specific maintenance tasks and inspections, oil consumption programme details, service check requirements, MMEL dispatch restrictions, and approved EDTO parts with their life limits. Understanding the CMP document is essential for CAMO professionals managing EDTO-capable aircraft.

RVSM (Reduced Vertical Separation Minima) requires aircraft operating between FL290 and FL410 to meet specific equipment and monitoring standards. Continuing airworthiness requirements include maintaining the ‘3+1’ equipment rule (two independent altitude measurement systems, one autopilot with altitude-hold, and one altitude alerting system), conducting pre-flight altimeter checks within specified tolerances, participating in height-keeping performance monitoring programmes, and ensuring MEL provisions address RVSM equipment dispatch limitations. The CAMO must ensure these requirements are reflected in the AMP and maintenance contracts.

NAT HLA (North Atlantic High Level Airspace) operations require specific navigation, communication, and surveillance equipment. This includes dual Long Range Navigation Systems (LRNS), navigation performance capabilities meeting RNAV 10, RNP 4, or RNP 2 specifications, Long Range Communication Systems (HF radio and/or SATCOM/SATVOICE), CPDLC (Controller-Pilot Data Link Communications), and ADS-C (Automatic Dependent Surveillance – Contract). The CAMO must ensure these systems are maintained, functional, and addressed in the MEL. This course covers equipment requirements per NAT Doc 007 and their continuing airworthiness implications.

All personnel involved in EDTO should be made aware of the special nature of EDTO, have an understanding of its impact on their job, and have the knowledge, skills, and ability to properly accomplish their tasks. This includes CAMO personnel involved in continuing airworthiness management and Part-145 maintenance organisation personnel involved in EDTO maintenance activities. The training programme should provide both initial and recurrent training and be approved by the competent authority as part of the CAME. This course is designed to satisfy these proposed training requirements.

EDTO maintenance contracts between CAMOs and Part-145 AMOs must specify the additional EDTO provisions within the scope of contracted work, including interface procedures, instructions, documents, tools, EDTO-approved parts, training requirements, and reporting obligations. The contracts should address the 12 core elements defined in Appendix IV to AMC1 CAMO.A.315(c), plus EDTO-specific requirements for dual maintenance limitations, EDTO pre-departure checks, verification programmes, parts segregation and configuration control, and EDTO significant systems reliability reporting. This course covers practical guidance on structuring these contracts effectively.

Yes. This course syllabus has been developed in full alignment with the EDTO training requirements defined in Section 6 (EDTO Training and Qualification) of the proposed Appendix VI to AMC to Part-CAMO – EDTO Considerations, as published in EASA's applicable AMCs & GMs. The course covers every training topic specified in Section 6.1, including the introduction to EDTO regulations, type design approval considerations, EDTO operations approval, all nine EDTO continuing airworthiness elements, propulsion system monitoring, relevant CAME, MOE and ATL procedures, and maintenance contracts and interface procedures between the CAMO and the Part-145 AMO. This makes the course suitable for both initial and recurrent EDTO training as envisaged by the proposed regulatory framework, satisfying the requirement that EDTO training programmes be approved by the competent authority as an integral part of the CAME.
