The European Union Aviation Safety Agency (EASA) has announced the most comprehensive update to Europe’s flight simulator qualification rules in decades, introducing a new framework that reflects how modern simulation technology has evolved and how pilots are trained today.
The changes, introduced under Regulation (EU) 2026/781 alongside Certification Specifications (CS-FSTD Issue 1), replace the long-established method of classifying Flight Simulation Training Devices (FSTDs) by fixed qualification levels. Instead, the new regulations assess simulators based on the capabilities they actually provide, creating a more flexible system that can adapt as technology continues to advance.
The overhaul is intended to support innovation, modernise pilot training and ensure regulatory standards remain relevant as aircraft and simulation systems become increasingly sophisticated.
A Significant Change for Flight Simulation
Flight simulators have become indispensable across commercial aviation, allowing pilots to practise normal operations, emergency procedures and complex scenarios without leaving the ground. They not only improve safety but also reduce operating costs, minimise aircraft downtime and lower fuel consumption and carbon emissions compared with conducting the same training in real aircraft.
Despite rapid improvements in simulation technology over the past two decades, the regulatory framework used to qualify these devices has largely remained unchanged. EASA believes that approach no longer reflects the capabilities of today’s advanced simulators.
Under the new framework, qualification will no longer depend primarily on predefined simulator categories. Instead, regulators will evaluate each device according to the training tasks it can realistically perform and the level of fidelity it offers.
The shift gives manufacturers and training providers greater flexibility while ensuring pilots continue to receive training that accurately reflects modern aircraft operations.
Moving Beyond Traditional Categories
For many years, flight simulators have been grouped into qualification levels that determined how they could be used during pilot training and recurrent checks.
While those classifications helped standardise training across the industry, they also limited the ability to recognise new technologies that did not fit neatly into existing categories.
Today’s simulators often include highly detailed visual systems, sophisticated motion platforms, touchscreen cockpit displays and increasingly immersive digital environments. These advances have blurred the distinction between traditional qualification levels.
EASA’s capability-based approach acknowledges those developments by focusing on what a simulator can actually do rather than the category assigned to it years ago.
The agency believes this will make it easier to introduce future technologies without requiring major regulatory revisions every time simulation capabilities improve.
Introducing the FSTD Capability Signature
One of the centrepieces of the new regulations is the introduction of the FSTD Capability Signature (FCS).
The Capability Signature provides a standardised description of each simulator’s performance using defined features and fidelity levels. Rather than relying on broad classifications, every training device will have a detailed capability profile that clearly identifies the functions it can support.
This gives regulators, airlines and Approved Training Organisations (ATOs) a far clearer understanding of how each simulator can be used within a training programme.
The new system also provides manufacturers with greater flexibility when developing or upgrading simulation equipment, as improvements can be recognised without forcing the device into an entirely different qualification category.
Preparing for the Next Generation of Training
Another important aspect of the framework is its recognition of emerging technologies that are becoming increasingly common in modern cockpits.
The regulations introduce qualification guidance for innovations including touchscreen flight deck interfaces and Extended Reality (XR) applications, ensuring these technologies can be incorporated into approved training programmes under a consistent regulatory structure.
As aircraft manufacturers continue introducing more digital flight decks, simulation devices must evolve alongside them to provide realistic and effective training environments.
By addressing these technologies now, EASA aims to create a framework that remains relevant for years rather than requiring continual updates.
A More Flexible Training Philosophy
The revised rules also introduce an optional task-to-tool training methodology that allows Approved Training Organisations and aircraft operators to match specific training exercises with the most appropriate simulation device.
Rather than assigning every task to a predetermined simulator category, instructors can choose equipment based on the complexity and objectives of the lesson.
This approach enables training organisations to make better use of their available resources while maintaining the high safety standards expected throughout European aviation.
Simple procedural exercises can be completed using devices designed for those purposes, while more demanding scenarios continue to require advanced full-flight simulators.
The result is greater flexibility in programme design without compromising training quality.
Supporting Innovation Without Sacrificing Safety
EASA says the updated framework has been designed to encourage technological innovation while preserving the rigorous safety oversight that underpins European aviation.
According to Francesco Gaetani, the agency’s Flight Standards Director, flight simulation has transformed pilot training over the past several decades and will continue to play an increasingly important role as aviation technology evolves.
He said the revised framework reflects the real capabilities of modern training devices instead of relying on legacy classifications, making it easier to integrate new technologies while ensuring pilots continue to receive effective, high-quality instruction.
His comments highlight EASA’s intention to create regulations that evolve alongside industry innovation rather than slowing its adoption.
Benefits Across the Aviation Industry
The new framework is expected to deliver benefits for airlines, training providers, simulator manufacturers and regulators alike.
Manufacturers will have greater flexibility when developing new products and upgrading existing devices. Training organisations should be able to optimise simulator utilisation more effectively, while airlines may benefit from more efficient training programmes that better align simulation capabilities with operational requirements.
For pilots, the reforms are expected to provide access to training that more accurately reflects the aircraft and technologies they encounter in daily operations.
As the aviation sector continues to address pilot shortages, increasing demand for training capacity and the rapid pace of technological change, flexible simulation standards are becoming increasingly important.
Looking Ahead
EASA’s latest reforms represent a significant milestone in the evolution of European pilot training.
By replacing fixed qualification levels with a capability-based framework, the agency has created a system that is better suited to modern simulation technology while remaining adaptable for future developments.
As innovations such as immersive digital environments, advanced cockpit interfaces and extended reality become more widely adopted, the updated regulations provide a foundation that can evolve alongside them.
Ultimately, the changes reinforce the role of flight simulation as one of aviation’s most valuable safety tools while giving Europe’s training industry the flexibility needed to prepare the next generation of airline pilots.
