Task to Tool: Why EASA's Biggest Simulator Reform in Decades Matters

When the European Union Aviation Safety Agency's new Flight Simulation Training Device (FSTD) Capability Signature (FCS) framework comes into force in April 2028, it will mark the biggest change to aviation training device qualification in more than two decades.

Known across the industry as "Task to Tool," the new approach fundamentally changes a simple but important question. Instead of asking what training can this simulator deliver?, regulators, airlines and manufacturers will increasingly ask what training do we need to deliver, and what capabilities are required to support it?

For airlines facing growing pilot demand, simulator manufacturers investing in new technologies, and regulators trying to accommodate everything from XR to remotely piloted aircraft, many believe the shift is long overdue.

Turning simulator qualification upside down

The traditional regulatory model classifies simulators into fixed categories—such as Full Flight Simulator Level D or Flight Training Device Level 2—with training credits determined largely by those classifications.

Task to Tool reverses that logic.

"It sounds like a small change, but it's actually a wholesale change," says Captain Philip Adrian, CEO of MPS and former chair of EASA's Rulemaking Task 196, which developed the concept.

"Instead of looking at a motion device as automatically being the top of the line, we've identified 14 individual capability features. Organisations can now ask what training they actually need to deliver, rather than buying capabilities they may never use."

From motion and visuals to flight modelling, aircraft systems and environmental simulation, those 14 capability areas form each device's new Flight Simulation Training Device Capability Signature (FCS). Training tasks are then matched against those capabilities rather than against traditional device classifications.

According to Andrew Bell, FSTD Lead Inspector at the UK Civil Aviation Authority, this reflects how modern simulation technology has evolved.

"Today's fixed-base devices are often capable of far more than the regulations give them credit for. Many can safely support training objectives that currently require a full flight simulator simply because the regulations haven't kept pace with technology."

A technology-neutral framework

"The new capability-based approach is designed so that future technologies—even ones we haven't imagined yet—can be accommodated within the same structure."

For companies developing immersive technologies, that flexibility could prove transformative.

TJ Moser, Federal Account Executive at Varjo and a former U.S. Air Force pilot who helped introduce immersive training across Air Force pilot training, believes Task to Tool creates a far clearer pathway for XR-based devices to receive meaningful regulatory recognition.

"I don't think the full-flight simulator is going away," he says. "But there are many training tasks that simply don't require a multi-million-dollar simulator."

Instead, immersive technologies can deliver cockpit familiarisation, checklist training, upset recovery, visual manoeuvres, spatial orientation and local area familiarisation far more efficiently.

"There is definitely a space for XR," says Moser. "Task to Tool recognises that different tools are appropriate for different tasks."

Learning from military training

Although the framework represents a major change for civil aviation, the underlying philosophy has been commonplace in military aviation for decades.

"The military has effectively been doing this since day one," says Moser.

Rather than qualifying every simulator to perform every task, the U.S. Air Force routinely selects devices according to individual training objectives.

"If a device teaches a particular manoeuvre effectively, we use it. It doesn't have to do everything."

That philosophy has allowed the Air Force to deploy dozens of lower-cost immersive trainers directly onto training bases rather than relying solely on a handful of expensive full-mission simulators.

Moser believes civil aviation could ultimately adopt a similar distributed model, bringing more training closer to pilots while optimising the time spent in high-end centralised training centres.

Better evidence, not just better hardware

Task to Tool also changes how new technologies may ultimately be evaluated.

Instead of qualifying devices primarily against technical specifications, future assessments are expected to place increasing emphasis on demonstrated training effectiveness.

That shift aligns closely with wider developments in competency-based training and evidence-based assessment.

Moser points to technologies such as eye tracking, attention analysis and cognitive workload measurement as examples of the kinds of evidence that could strengthen future qualification decisions.

Rather than simply recording whether a pilot made an error, immersive systems increasingly reveal why.

"If somebody busts an altitude, was it poor situational awareness—or were they fixated on another task? Eye-tracking data can answer that."

More flexibility—but also more complexity

The transition will not be straightforward.

Existing qualification levels will gradually disappear, replaced by individual capability signatures. Airlines, simulator manufacturers, regulators and Approved Training Organisations will all need to rethink procurement, qualification and course design.

Bell believes the industry should not underestimate the scale of the transition.

"This is the biggest change we've ever seen," he says.

"There will be organisations that leave it until the last minute. That's going to be difficult because every part of the simulator ecosystem is affected—from manufacturers and regulators to training organisations and operators."

EASA has already recognised that challenge by allowing a two-year transition period before mandatory implementation begins.

A global direction of travel

Although the UK is no longer directly involved in EASA rulemaking, Bell expects the Civil Aviation Authority to pursue a closely aligned approach once the necessary domestic rulemaking process is complete.

Meanwhile, ICAO's Personnel Training and Licensing Panel (PTLP) is already working to incorporate the same principles into ICAO Document 9625, potentially laying the foundation for broader international harmonisation.

Adrian also points to growing Federal Aviation Administration interest following recent joint discussions between EASA, the FAA, airlines and manufacturers.

"The industry shouldn't wait," he says.

"Rulemaking always takes time. Use what's available today, optimise training now, and don't wait for something better tomorrow."

Training becomes the starting point

Ultimately, Task to Tool represents more than a technical update to simulator qualification. It reflects a broader shift in aviation training philosophy, from classifying devices by what they are to measuring them by what they enable.

As new technologies continue to reshape pilot training, regulators are increasingly moving away from prescribing hardware and towards defining capability.

For an industry under constant pressure to train more pilots without compromising safety, that may prove to be the framework's most important innovation.
