The Compliance Puzzle Facing Aviation Trainers

Approved training organisations (ATO) operating across multiple jurisdictions face the ongoing challenge of maintaining regulatory compliance while managing variations in how individual civil aviation authorities interpret and implement international standards. As training technologies evolve and competency-based approaches become more widely adopted, questions of regulatory harmonisation and divergence continue to shape operational requirements for ATOs. This article examines current practices in managing multi-authority approvals, areas where regulatory interpretation varies, and the emerging role of artificial intelligence in aviation training delivery.

Training Regulations and Regulatory Oversight

The CAE regulatory affairs team affirms that civil aviation authorities (CAA) around the world share the same fundamental mission of ensuring aviation safety. “Training is an essential component of this mandate, and ATOs play a key role in supporting it”, the team says. “As an ATO, CAE designs programmes that comply with the standards and guidelines applicable in each jurisdiction in which we operate. Differences between states typically arise in how each authority interprets and implements ICAO guidelines. Many organisations adopt a methodology aligned with their regional authority. EASA and the FAA, for example, are often considered global frameworks for training and licensing requirements”.

When an ATO is approved by a single state, regulatory alignment is straightforward. However, for ATOs operating with multiple regulatory approvals, each state’s specific requirements must be addressed within the training programme, according to the CAE regulatory affairs team. “This is typically achieved through structured gap analyses starting with a basic programme to ensure all regulatory nuances are met. As the number of regulatory approvals increases, so does the potential variance between training programmes”, the team affirms. “Opportunities for further harmonisation exist through the application of ICAO Document 9841 (Manual On The Approval Of Training Organizations), which provides a path for regulators to recognise foreign ATO approvals. Wider adoption of these guidelines could reduce duplication, promote consistency, and bring further efficiencies for regulators, operators, and ATOs”.

Acron Aviation collaborates with several national authorities. “Considering the significant discrepancies in the interpretation and application of aviation training regulations in these global regions, overall harmonisation is generally very good. In other words, as a company headquartered in the UK, EASA, and the US, it is widely accepted that the training we provide and the standards we adhere to meet or exceed globally accepted practices”, says Joel Young, deputy head of training at Acron Aviation. “As a training organisation, we currently provide training services on every continent on the planet, which has helped us gain the expertise needed to expedite approvals and manage individual national discrepancies when they arise”.

Aviation authority approvals, in most cases, are still a world of phone calls or targeted emails, and Acron Aviation has worked to build strong relationships over the years, affirms Young. “Having dealt with several national authorities, the greatest challenge was clarifying the required regulatory steps between authorities. Most authorities expect an organisation to meet a given authority’s own expectations or those of the higher-level regulator. Whichever is higher, this can vary depending on the regulatory framework and can therefore be interpreted by the individual ATO”, he says. “This often means modifying the regulatory impact to meet the minimum requirements. This comes with an additional level of approval with an organisation’s own authority as the basic approval. It varies from region to region, but most authorities are very pragmatic in formulating solutions”.

Divergence and Alignment

One emerging area of divergence, both within a single regulator and across multiple regulators, concerns the application of competency-based training and assessment (CBTA) and the differing interpretations of key aspects of this paradigm shift in aviation training and assessment, Andrew Mitchell, head of training at FTE Jerez, points out. “The approach adopted in the creation of existing CBTA regulations - such as multicrew pilot licensing (MPL), airline pilot standards multi crew coordination (APS MCC), Area 100 knowledge, skills, and attitude (KSA), evidence-based training (EBT) - has led to significant complexity, particularly within ATOs, in the implementation of multiple assessment and training systems that are not fully compatible with each other, but all ‘competency-based’”, he says. “It is not uncommon for instructors within an ATO to need to standardise on up to five different assessment systems across legacy pilot courses and CBTAs within a single ATO, and it is very likely that none of them are aligned with the airline’s competency-based assessment systems. A unified global approach to competency-based training and assessment would deliver significant efficiencies, with a positive impact on safety”.

Within EASA Member States, FTE Jerez is seeing divergences among national competent authorities in individual Member States in their interpretation of mandatory regulations, affirms Mitchell. “While an EASA Examiner Differences Document exists to guide EASA examiners on the differences between authorities’ requirements for skill tests, licensing proficiency checks, and competence assessments, there is no similar document explaining how Member States interpret other aspects of EASA Part-FCL requirements”, he says. “This can lead to specific issues with license applications that other EASA Member States would not experience. ATOs may end up adopting a trial-and-error approach to managing this risk, a single guide on differences detailing where Member States are more restrictive would be valuable in ensuring an efficient course completion/license application process on a level playing field”.

Looking at regulatory convergence from an ATO perspective, Young believes that the adoption of regulatory alignment between EASA and the Middle East has been excellent over the past five years. “Many Middle East airlines are already affiliate members and promptly adopt all changes implemented by EASA, they often turn to us for guidance on implementation. As with any region, there are always geopolitical considerations, but we are currently working closely with many Middle Eastern carriers, from Oman to Saudi Arabia, to help them develop their training plans and harmonise their operations”, he says. “These airlines and their respective authorities have been brilliant in reducing potential delays, allowing us to act quickly”, he says. “We recently conducted an audit with a major Middle Eastern carrier, which yielded zero findings after a week of auditing, a clear indication for us of how aligned our values, standards, and objectives are”.

AI-Powered Tools and Simulation Technologies

Technological development is evolving faster than regulation, and aviation authorities are increasingly using standards and operational use cases to inform updates, the CAE regulatory affairs team observes. “Rather than prescribing specific technologies, which risk becoming obsolete once regulation is completed, regulators are focussing on defining the conditions and regulatory frameworks necessary to safely introduce emerging capabilities. This approach allows authorities to create performance-based regulatory structures while fostering industry innovation”, the team says. “It also supports a more flexible path for the adoption of AI-based systems, simulation improvements, and data-driven training tools. As new technologies mature, regulators are working to identify potential risks, define acceptable use cases, and develop guidelines tailored to the expected level of automation, human interaction, and operational complexity”.

Young notes that both EASA and the UK CAA have taken bold steps to facilitate artificial intelligence (AI) roadmaps for aviation training, while ICAO is being cautious, yet proactive in this area. “We fully agree with ICAO. The potential for divergence between NAAs and regional authorities is enormous if there is a struggle to innovate or drive AI without guidance from the leading global authority. We are already seeing the results of this among our higher-level authorities in the most basic airline functions such as fuel policy, low visibility operations (LVO), and CBTA-led functions and this creates enormous complexity for global organisations like ours”, he says. “Authorities agree on the need to use proven AI platforms to reduce workload, and to some extent, this should be left to the ATO, provided they can demonstrate a proven process and change management framework”.

The challenge for most airlines is how to measure their position compared to everyone else in the industry, affirms Young. “As a global ATO, we are fortunate to generate global data that allows us to use leading AI capabilities to help us interpret vast amounts of data and guide airline training formats. Simply put, we need to free our instructors from basic manual tasks to allow them to apply their expertise in interpreting trainees' needs and facilitating such improvement”, he says. “We then need robust, recognised tools to interpret that data and improve our training plans. As I have said, tailored training is the goal, and these basic AI tools bring us one step closer, but only if it occurs in a clearly regulated environment. To achieve this, we clearly need regulatory harmonisation based on solid data and practical demonstration”.

Summing Up

Regulatory harmonisation in aviation training remains achievable despite variations in how individual authorities interpret international standards. ATOs with multi-jurisdictional approvals continue to manage compliance through structured gap analyses and direct engagement with regulators. While challenges persist - particularly around competency-based training implementation and varying Member State interpretations - the fundamental alignment between major regulatory frameworks supports operational efficiency. As AI and advanced training technologies develop, performance-based regulatory approaches offer a practical path forward, provided global coordination through ICAO prevents fragmentation.
