Reflecting on Airspace World in Lisbon (25–27 May), one of my key takeaways came from a remark by Filip Cornelis, Director for Aviation at the European Commission.
Speaking about the rollout of Europe’s dedicated drone airspace framework—U-space—he candidly acknowledged that the framework has become overly complex and that operationalizing it poses significant challenges for Member States and industry stakeholders alike.
I found this observation both refreshing and important.
Europe is arguably the world’s most advanced region when it comes to enabling BVLOS operations and integrating drones into the airspace. Yet even there, stakeholders are discovering that writing regulations is only the beginning. The greater challenge lies in translating those frameworks into operational reality.
But perhaps the most interesting lesson is not that complexity exists.
It is how Europe is responding.
Learning to Navigate Complexity
Rather than retreating or simply adding more layers of process, the European aviation community is increasingly embracing collaborative approaches.
The U-space Implementation Handbook, developed under the U-ELCOME project, was created specifically to help authorities and stakeholders navigate implementation challenges and operational bottlenecks.
Collaborative simulation initiatives involving Airbus and EUROCONTROL are enabling procedures, risk profiles, and operational concepts to be tested safely before large-scale deployment.
At the same time, increasing emphasis is being placed on resilience, harmonization with the European ATM Master Plan, and mitigating emerging threats such as GNSS interference.
These are not signs of failure.
They are signs of a community learning how to navigate complexity.
And therein lies an important lesson for the rest of us.
The Challenge Is Not Technology
Listening to discussions throughout Airspace World, I came away with the impression that aviation’s greatest challenge is not technological complexity.
Technology is advancing rapidly. Aircraft and communication, navigation, and surveillance capabilities continue to improve. Digital platforms, AI, and automation are progressing at remarkable speed.
At the same time, an acceptable level of safety must always be maintained.
What is proving far more difficult is the ability of organizations and institutional arrangements to keep pace.
In other words, the challenge is increasingly one of organizational complexity and institutional constraints.
We are asking regulators, ANSPs, airports, operators, manufacturers, and governments to simultaneously address modernization, digitalization, cybersecurity, resilience, sustainability, AI, automation, workforce shortages, and the integration of entirely new entrants into the airspace.
Yet many of the institutions and governance structures responsible for enabling this future were designed for a more stable and predictable era, when change was slower and easier to anticipate.
They were built to manage complicated systems that delivered predictable outcomes.
Today, they are increasingly being asked to operate in an environment where outcomes are far less known and predictable.
Aviation itself illustrates the distinction.
Air transport is a highly regulated and procedural activity characterized by clearly defined rules, processes, and responsibilities. It is complicated but we know how it works.
Yet it operates within a complex environment involving weather, differing regulatory frameworks, evolving technologies, economic pressures, and the interactions among many actors. It is complex. With many moving parts, actors whose actions and reactions are difficult to anticipate, information that is often ambiguous, and rapid and continuous change, outcomes become inherently less predictable.
The Need for Institutional Evolution
The institutions and governance structures that have served aviation extraordinarily well over the past decades have delivered levels of safety and reliability unmatched by almost any other industry.
But the challenge is no longer simply one of dealing with new technologies and systems.
It is one of evolving the organizations and institutional arrangements themselves.
To keep pace with accelerating innovation, aviation’s organizations and institutional arrangements must evolve into more adaptive ecosystems—capable of learning, collaborating, experimenting, and responding more rapidly to change.
Perhaps the future challenge is not simply one of dealing with twenty-first century technologies.
It is one of rethinking and evolving twentieth century organizations, institutional arrangements, and building the collaborative ecosystems needed to navigate an era of accelerating change.
Belgium: From Frameworks to Operations
One example that particularly stands out is Belgium and its embrace of advanced drone operations.
Rather than treating regulation as the end in itself, Belgian stakeholders have viewed it as part of the solution, focusing on operationalization—where the value to industry, society, and the economy ultimately lies.
Belgium has become one of the first countries to move beyond concepts and demonstrations toward routine BVLOS cargo drone operations.
Stakeholders across government, regulators, ANSPs, technology providers, and operators have worked together to create an ecosystem that enables real operations and real learning.
This collaborative approach was recognized through the shortlisting of Belgian stakeholders for the 2026 CANSO Seamless Skies Awards announced during Airspace World.
Although they did not make the final cut, the recognition itself speaks volumes.
Innovation ecosystems are not built by optimizing individual organizations.
They are built by aligning the system around shared outcomes that deliver value to industry, the economy, and society at large.
Belgium demonstrates that complexity need not become an excuse for delay.
It can become a catalyst for collaboration, experimentation, and collective problem-solving within an ecosystem of stakeholders.
A Lesson for North America
For North America—and Canada in particular—Europe’s experience offers valuable lessons.
The objective should not be to replicate the European model.
Every region has its own institutional structures and realities.
But there is little need to reinvent every process or relearn every lesson.
Europe’s experience suggests that progress depends less on isolated initiatives and more on collaborative ecosystems, shared implementation guidance, experimentation, pooled expertise, and more agile approaches to deployment.
In many respects, Europe has become an evolving laboratory from which others can learn.
Perhaps North America has an opportunity to leapfrog some of the institutional growing pains by adopting more systems-oriented and adaptive approaches from the outset.
Seeing the Whole
We live and work in systems.
One lesson I have learned over the years is that when systems appear not to be working, the instinctive response is often to conclude that the system itself is broken.
Yet systems rarely underperform because everything is broken.
More often, a relatively small number of constraints, hidden bottlenecks, or assumptions that no longer fit the environment are preventing the system from performing as intended.
Understanding the whole system—and the relationships among its parts—often matters more than optimizing or replacing the system itself.
Complexity is not a problem to be solved.
It is a reality to be navigated.
And perhaps the most effective means of navigating complexity are meaningful engagement and collaboration.
Not because consensus is always possible.
But because shared understanding, continuous learning, and ecosystem-wide adaptation are what ultimately enable complex systems to evolve.
If done well, success follows.
And with it, the societal and economic value that technologies such as BVLOS operations, #AdvancedAirMobility (AAM), and digital airspace management promise to deliver.
Perhaps the greatest challenge facing aviation today is not technological complexity.
It is institutional complexity.
And perhaps the answer is not to try to do more, especially when resources are finite.
But to think—and do—different.
That, for me, was one of the most important lessons I brought home from Lisbon.
