High Reliability: What Commercial Aviation Can Teach and Export to the World of Complex Industries

By: Giacomo Belloni

Commercial aviation today represents one of the most advanced and reliable socio-technological systems, capable of combining operational complexity, safety and efficiency. Available data clearly confirms this hypothesis. The International Air Transport Association (IATA) reports that approximately 38.7 million commercial flights were operated in 2025, carrying nearly 5 billion passengers. Despite these impressive numbers, 51 fatal accidents were recorded, including 8 that resulted in 394 fatalities (IATA, 2026). This translates to an accident rate of approximately 1.32 per million flights and an extremely low risk of fatality, approximately 0.17 per million flights (IATA, 2026). Even accounting for annual variations, the long-term trend is unmistakable: the accident rate has decreased significantly over the last two decades, from approximately 3.72 per million flights in 2005 to current levels near 1 per million (IATA, 2026). Similarly, data from the International Civil Aviation Organization (ICAO) show a steady trend toward improving global safety, despite continued growth in air traffic (ICAO], 2025). These figures place aviation among the so-called High Reliability Organizations, i.e., organisations that operate in high-risk environments while maintaining extremely low levels of error (Weick & Sutcliffe, 2007).

The reasons for these achievements are multiple and have been thoroughly studied in the scientific literature. A first fundamental element is the global standardisation of processes and regulations, which drastically reduces operational variability, one of the main risk factors in complex systems (Reason, 1997). Added to this is a strong safety culture, often referred to as a "just culture," in which operators are encouraged to report errors and anomalies without fear of sanctions, thus fostering continuous learning at the organisational level (Dekker, 2012). This approach is based on a systemic view of human error, which is considered not the primary cause of accidents but a symptom of deeper critical issues within the system (Reason, 1997).

In parallel, aviation has developed an extremely advanced use of data through continuous operations monitoring systems and predictive risk analysis, enabling intervention before critical events occur (IATA, 2026).

Another significant, often overlooked, element is the intrinsically multicultural nature of the sector: crews, air traffic controllers, technicians, and operators come from diverse national and cultural backgrounds, yet work according to shared standards. This fosters a continuous exchange of operational practices and the rapid diffusion of innovations, creating a global ecosystem of distributed learning.

Among the most relevant practices that can be exported to other industrial contexts is certainly competency- based training, known as Competency-Based Training and Assessment (CBTA). This model transcends the traditional approach based on hours of training, focusing on developing observable, transferable, and trainable competencies applicable across sectors. In the aviation field, these skills include not only technical abilities, but above all, soft skills essential for operating in complex and dynamic environments. Among these, effective communication is a key element: the use of standardised phraseology, clarity, and mutual verification of information drastically reduces the risk of misunderstanding, a critical factor in many historical accidents (Helmreich et al., 1999).

Situation awareness, or the ability to perceive, understand, and anticipate the evolution of an operational situation, is another key competency, heavily trained through simulations and complex scenarios; studies show that a loss of situational awareness is among the main causes of human error in high-risk environments (Endsley, 1995).

Alongside these, leadership and teamwork play a fundamental role: in the cockpit, leadership is not authoritarian but adaptive, capable of integrating diverse contributions and fostering a climate in which each crew member can express concerns or report anomalies. This model, developed through Crew Resource Management (CRM), is now considered a benchmark for team management in critical contexts (Helmreich et al., 1999).

Another set of exportable abilities peculiar to the commercial aviation industry concerns stress and cognitive load management, decision-making under uncertainty, and operational resilience. Pilots are trained to use structured decision-making models that include sequential phases of information gathering, option analysis, selection, and outcome verification, thus reducing the impact of cognitive biases (Klein, 2008). This approach is particularly relevant in contexts such as healthcare and emergency management, where decisions must be rapid yet robust. Simulation-based training also allows for the development of abilities that are difficult to acquire through direct experience alone, especially for rare but high-impact events. Studies in human factors demonstrate that training based on realistic scenarios significantly improves individual and team performance (Salas et al., 2006).

Alongside individual and team skills, aviation offers highly transferable organisational practices. Standard Operating Procedures (SOPs) ensure consistency and predictability, while the systematic use of checklists supports human memory and reduces errors of omission (Gawande, 2010).

Moreover, Safety Management Systems (SMS) represent an integrated and proactive approach to safety, based on risk identification, continuous monitoring, and constant improvement (ICAO, 2025). However, what makes this set of practices truly effective is their integration into a coherent system, supported by a learning-oriented organisational culture.

Despite the evidence of benefits, the transfer of these practices to other sectors still faces significant obstacles. Cultural differences, particularly the persistence of punitive approaches to error, limit the diffusion of models based on transparency and learning. The lack of standardisation and fragmented regulations makes it more difficult to adopt uniform procedures. At the same time, the inherent variability of some operational contexts can complicate the application of models developed in the aviation sector. Furthermore, implementing advanced training and monitoring systems requires significant investment. However, aviation experience demonstrates that such investments yield significant benefits in safety, efficiency, and reliability.

In conclusion, commercial aviation is not only a technologically advanced sector but also a true laboratory for organisational innovation. The skills developed within it—from communication to situational awareness, from leadership to decision-making—are largely trainable and exportable and constitute a

valuable asset for all organisations operating in complex environments. The global and multicultural nature of the sector further amplifies this value, fostering a continuous exchange of practices and knowledge. Rather than replicating individual tools, other sectors can benefit from adopting the systemic logic that characterises aviation: an approach in which technology, people, and organisation are integrated into a single system focused on safety and continuous improvement.
