At the 2024 International Society of Air Safety Investigators (ISASI) conference in Lisbon, more than 300 experts gathered to explore the theme "Safely Navigating Uncharted Waters." Industry leaders, regulators, manufacturers, and accident investigation agencies came together to discuss how technological innovation is shaping the future of aviation safety.

TAP Air Portugal’s Contribution: Data-Driven Safety Monitoring

Representing TAP Air Portugal, Pedro Soares, a Flight Data Expert, presented a study titled “Integration of a Terrain Database for Terrain Awareness and Warning System (TAWS) Event Monitoring.”

The research utilizes a global terrain database to analyze alerts generated by the Enhanced Ground Proximity Warning System (EGPWS). Soares explained how small variations in terrain data—evaluated through complex algorithms—can determine whether an alert is triggered during flight.

“The project involved modeling terrain around airports to define safety zones for approach maneuvers. When the flight path intersects one of these mapped zones, an alert is issued," Soares noted. "We then combine flight data with terrain information to verify if the EGPWS warning was legitimate.” This precise, data-driven analysis ensures that TAP can differentiate between valid alerts and false positives, enhancing operational safety.

Developed as part of a Master’s thesis from a trainee in TAP’s Safety Department, the study highlights the value of collaboration between academia and industry in advancing aviation safety. “Applying this technique in real scenarios where 'Terrain Ahead' warnings were triggered confirmed the reliability of the model, particularly due to the visual insights it provides,” Soares added.

The Future of Aviation Safety: Technology and Expertise

Barbara Dunn, President of ISASI, emphasized the role of technology in modern investigations. “Virtually every incident today is captured on a mobile device, providing insights that were unimaginable in the past,” she said. Soares agreed, highlighting the importance of flight data. “Aircraft now transmit vast amounts of information, opening up new possibilities for safety improvements,” he noted.

However, both Dunn and Soares stressed that effective data management is essential. “Understanding the limitations and context of the data is critical,” Dunn explained. Advances in artificial intelligence, simulation tools, and data analytics are transforming investigations but require new expertise to unlock their potential. “Integrating the right data at the right time is paramount for successful investigations,” she added.

TAP’s Commitment to Leadership and Safety Excellence

For TAP Air Portugal, ISASI 2024 was an opportunity to showcase its commitment to safety innovation and reinforce its leadership in the field. “Sharing our findings with the industry strengthens TAP’s position as a front-runner in using flight data to enhance safety and operational efficiency,” said Soares.

TAP’s dedication to safety has earned it a perfect seven-star safety rating on AirlineRatings.com, and the airline is consistently recognized in our annual list of the world’s safest airlines.

To Soares, specialized events like ISASI provide a unique opportunity to exchange ideas and accelerate the adoption of new safety practices. “These conferences allow us to discuss technologies with industry peers, gaining immediate feedback on their practical applicability," he explained. "Hearing directly from regulators, researchers, and operators who have tested these innovations helps us better assess their potential for real-world use.”

Pioneering Innovation Through Academia-Industry Collaboration

TAP Air Portugal has a long tradition of partnering with Portuguese universities in Aerospace and Aeronautical Engineering to foster innovation. The terrain monitoring system presented at ISASI exemplifies how academic research can translate into practical safety improvements.

“With narrower margins for error in today’s aviation environment, precision and reliability are more important than ever,” Soares emphasized. Innovations like TAP’s terrain mapping tool underscore the value of combining cutting-edge research with real-world application. By continuing to invest in technology and academic collaboration, TAP remains at the forefront of aviation safety.

As TAP continues to enhance its operational capabilities, it also reinforces its status as one of the world’s leading airlines in safety. Through initiatives like these, the airline ensures that passengers and crew are secure in a constantly evolving industry—further cementing its reputation as a global leader in aviation safety.
