When the aviation and technology sectors feel the need to repeatedly state that innovation is meant to support rather than replace human beings, it is only natural to question the direction this transformation is taking. The history of major industrial evolution teaches us that every technological change brings extraordinary opportunities, but also raises questions that deserve to be addressed with a critical spirit and a long-term vision.
The echoes of Airspace World 2026 the leading global forum dedicated to air traffic management, held at the Feira Internacional de Lisboa from 26 to 28 May offer a valuable opportunity for reflection. Behind the showcase of technological innovation and the new digital platforms presented by the sector’s key players, a debate has unfolded that concerns the very future of aviation professions. A future that, in seeking to address the chronic shortage of qualified personnel, could gradually alter the role of the human being within operational processes, raising important questions about the preservation of skills and decision-making capacity.
The Technological Showcase of Lisbon
The themes emerging during the forum reflect a reality well known to industry operators. European airspace continues to face growing operational pressure, influenced both by geopolitical tensions that have reshaped numerous international routes, and by the difficulty of rapidly replacing highly specialised staff reaching retirement age.
Against this backdrop, digitalisation represents one of the main strategic responses. Among the solutions presented, Indra’s Linkia platform demonstrated how advanced digital architectures can integrate and coordinate complex Air Traffic Management (ATM) systems, while other industry players illustrated applications based on Artificial Intelligence and assisted automation.
The proposed technologies aim to simplify activities that traditionally absorb a significant portion of operators’ cognitive workload: digitalisation of phraseology, automatic entry of flight data, coordination between operational sectors, conversion of voice communications into structured data, and support for trajectory management.
The stated objective is clear: to reduce workload, increase operational efficiency, and allow air traffic controllers to focus on the most relevant decision-making aspects.
Significant progress is also being made in the field of cybersecurity. New modular, distributed software architectures are designed to increase system resilience, limiting the spread of any faults or cyberattacks. At the same time, concepts such as Cloud ATM and digitalised services are being developed, which could in future allow the rapid transfer of certain operational functions to remote centres capable of ensuring service continuity in the event of local disruptions.
From an engineering perspective, these are important developments. However, the central question remains open: how can these technologies be used to strengthen the system without weakening the role of the human being, who represents its primary element of resilience?
Staff Shortages and the Need for a New Training Vision
The shortage of qualified professionals is not limited to air traffic control. Pilots, maintenance technicians, cabin crew, and many other roles across the sector are increasingly difficult to recruit and train.
In this context, technology could be used not only to compensate for staff shortages, but also to broaden access to aviation professions and improve the effectiveness of training.
Immersive technologies, such as Virtual Reality and Augmented Reality, already make it possible to recreate complex operational scenarios, allowing students to practise in realistic environments without the costs and risks associated with traditional training. Rare procedures, emergencies, and high-complexity situations can be repeated numerous times, accelerating the development of skills and enhancing situational awareness.
At the same time, training pathways could become more flexible, modular, and accessible, adapting to the needs of new generations without compromising the high safety standards that define the aviation sector.
But training alone is not enough.
There is a need to strengthen outreach in schools and universities, presenting the aviation sector in its true professional dimension. All too often, the world of aviation is portrayed exclusively through spectacular imagery or aspects related to travel, overlooking the vast ecosystem of technical, operational, and managerial expertise that ensures its daily functioning.
Engaging young people with these professions means building today the human capital that will be essential to sustain the sector in the coming decades.
The Risk of the Passive Supervisor
One of the most relevant themes to emerge in international debate in recent years is the gradual evolution of the human operator’s role.
In air traffic control, flight decks, and even maintenance activities, there is a growing trend to transfer to machines tasks previously performed directly by people. The operator thus assumes a role increasingly oriented towards supervising automated systems.
While this transformation offers undeniable advantages, it also refers to a concept well known to human factors specialists: the so-called “irony of automation”.
The more reliable and efficient an automated system becomes, the more human intervention is concentrated in exceptional situations. However, precisely because such situations occur rarely, there is a risk that the operator will gradually lose familiarity with certain fundamental operational skills.
In other words, the moment when human presence becomes most necessary often coincides with the moment when their capabilities may be least practised.
This phenomenon is particularly relevant in a context marked by the growing prevalence of cyber threats, interference with satellite systems, and unforeseen operational situations. Incidents of GPS jamming and spoofing recorded in recent years across various parts of the European continent demonstrate that operational resilience cannot rely solely on technology.
When an automated system degrades or becomes unavailable, the operator must be able to rapidly reconstruct the situational picture and make effective decisions in a short time. For this reason, maintaining manual and cognitive skills is a fundamental requirement for the future safety of the sector.
Technology and Responsibility
Another aspect worthy of attention concerns the relationship between automation and decision-making responsibility.
Many advanced systems are designed to provide increasingly sophisticated recommendations, formally leaving the final decision to the human being. This model preserves the principle of Human-in-the-Loop, but raises important questions about how decisions are actually made in highly automated environments.
When operators interact daily with systems that prove reliable over long periods, a natural trust in the guidance provided by the machine can develop. This is a well-documented phenomenon, studied for decades in the field of human factors.
The future challenge will therefore not only be technical, but also organisational and regulatory: ensuring that automation remains a tool to support the decision-making process, and that operational responsibilities are consistent with the actual level of autonomy of the systems employed.
Conclusions: Preserving the Value of Experience
The discussion opened in Lisbon is not about opposing innovation and tradition. Technology will inevitably continue to play a central role in the development of aviation, and no industry professional can ignore its benefits.
The fundamental question is how to integrate these innovations without compromising the wealth of experience, intuition, and adaptability that represents one of the pillars of aviation safety.
Staff shortages should not be addressed solely through increased automation, but also through structural investments in training, the attraction of new professionals, and the maintenance of operational skills.
Digital technologies can help reduce burnout, improve working conditions, increase efficiency, and make training pathways more accessible. They can help build a new generation of professionals who are better prepared and more aware.
To achieve this, training programmes must continue to preserve periods of manual operation and degraded scenarios, keeping those cognitive abilities sharp that become decisive when technology reaches its limits.
If air transport is to remain one of the safest and most reliable systems ever created, the digital transformation must be built while keeping the human being at the centre of the decision-making process. The principle of Human-in-the-Loop should not be seen as a relic of the past, but as an essential component of future operational resilience.
Technology can amplify human capabilities, reduce workload, and improve performance. However, the ability to interpret the unexpected, assess context, and make decisions under unforeseen conditions remains an inherently human prerogative.
The real challenge in the coming years will not be to choose between human and machine, but to build a balance where both can make the most of their respective strengths.q
