Why Crew Cognitive Resilience Matters in an Automated Aviation System?

Modern aviation is often described as data-rich, highly regulated, and increasingly automated. In many respects, this is true, and it has delivered extraordinary levels of safety and efficiency. Yet these same characteristics raise an important and often under-examined question:

What happens when safety and resilience depend on things we cannot easily measure?

Much of today’s regulatory assurance, safety management, and performance oversight is built around what can be observed, counted, audited, and demonstrated. Metrics thrive in stable conditions. Dashboards perform well when systems behave as expected. But cognitive resilience, the ability of humans to adapt, reframe, and intervene when systems degrade or behave unexpectedly, is rarely visible during normal operations.

This creates a quiet tension.

As automation becomes more capable, human intervention becomes rarer. When it is required, it is often time-critical, cognitively demanding, and poorly rehearsed. Decision-making, situation awareness, and trust calibration can degrade rapidly under uncertainty, yet these dynamics are difficult to capture through routine measurement or compliance indicators. In other words, the moments that matter most for resilience are often the moments we understand least.

This does not represent a failure of regulation, training, or technology. It reflects the reality of complex socio-technical systems. In such systems, safety is not only produced through rules and procedures, but through human adaptation at the edges — during transitions, surprises, degraded modes, and novel combinations of events.

This represents the current stance of the CCRI™ research; it remains intentionally provisional and open to evidence that may challenge, refine, or point towards alternative viable considerations.

What the CCRI™ Research Is — and Is Not

The Crew Cognitive Resilience Index (CCRI™) research programme is grounded in this gap between assurance and adaptation.

At its core, the research is not attempting to create another performance score, compliance metric, or ranking tool. Nor is it designed to assess or certify individual pilots. Instead, CCRI™ is a research framework intended to make visible aspects of cognitive performance that are currently implicit, assumed, or only revealed after things go wrong.

The refined stance of the research is deliberately cautious:

• CCRI™ is about understanding, not grading
• It is about revealing limits and trade-offs, not optimising people
• It treats cognitive resilience as a system property, not an individual trait
• It focuses on adaptation under uncertainty, not routine proficiency

The research asks questions such as:

• How does decision-making change when automation behaves unexpectedly?
• Where does cognitive load accumulate during rare, high-consequence events?
• How do trust, mental models, and situation awareness degrade — and recover — under surprise?
• Which aspects of human performance consistently sit outside current measurement and assurance frameworks?

By framing cognitive resilience in this way, CCRI™ does not seek to replace existing regulatory or training structures. Instead, it aims to complement them, by highlighting where confidence based on measurement may exceed actual understanding.

Why This Matters for Regulation, Automation, and Emerging Operations

As aviation moves towards more automation, AI-supported decision-making, and novel operational concepts such as eVTOL and Advanced Air Mobility, the pressure to demonstrate assurance will only increase. At the same time, operational experience will become more uneven: long periods of nominal performance punctuated by rare, demanding interventions.

In this context, the risk is not that we measure too little, but that we mistake measurability for resilience.

Crew Cognitive resilience offers a different lens. It invites regulators, designers, operators, and educators to consider how systems behave when certainty erodes, when procedures no longer fit cleanly, and when human judgment becomes the final line of defence.

Knowing what we do not know and designing systems that remain robust when our measurements are least reliable may be one of the defining safety challenges of the next decade.

CCRI™ exists to support that conversation.

Connecting the Research to Current Industry Dialogue

These questions will be explored further during my forthcoming involvement with the Royal Aeronautical SocietyCommercial Aviation Summit, taking place on 3–4 March in London.

I’m delighted to be moderating the Regulatory Landscape: Navigating New Challenges panel on Day 1 of the summit. The session will bring together perspectives from regulators, airport operators, and emerging aviation sectors to explore the current regulatory environment and what the future may hold for UK and international aviation.

Discussion will cover the practical effects of regulation on airline operations, including certification, licensing, maintenance, and supply chains, alongside emerging challenges linked to automation, new operational concepts, and evolving regulatory autonomy.

This panel provides an important opportunity to connect regulatory thinking with the human and cognitive dimensions of system resilience discussed in this research — particularly where assurance, automation, and adaptation intersect.
