ICAO high-level air navigation conference charts path for immediate and strategic enhancements for aviation sustainability

Montréal, 10 September 2024 – Representatives of the world’s governments have endorsed a suite of urgent actions to accelerate the aviation sector's transition to sustainability, while enhancing air safety and boosting operational efficiency.

The commitments emerged from the International Civil Aviation Organization's (ICAO) 14th Air Navigation Conference after nine days of intensive discussions in Montréal involving nearly 900 delegates from 110 ICAO Member States and 28 international organizations.

Their decisions are set to reshape the future of international air travel and transport. "This conference has resulted in concrete and actionable outcomes in critical areas," said ICAO Secretary General Juan Carlos Salazar. "From enhancing the resilience of satellite navigation to facilitating the introduction of electric aircraft, we have laid the groundwork for a safer, more efficient, and environmentally responsible aviation sector. These agreements reflect our sector’s commitment to innovation and adaptability in the face of unprecedented and evolving challenges."

Strategic alignment and technological advancements

Delegates strongly emphasized embracing technological advancements, with agreement on the need for harmonized regulatory frameworks to manage emerging technologies, including electric and hybrid propulsion.

In this context, the conference recommended implementing regulatory sandboxes, in other words, controlled testing environments for new aviation technologies. These sandboxes would allow for the collection of real-world data on emerging technologies like electric aircraft, while also providing opportunities to increase public awareness and acceptance of these innovations.

Another significant outcome of the conference was the call for enhanced mitigation of Global Navigation Satellite System (GNSS) interference, encompassing both deliberate actions like jamming or spoofing, and unintentional disruptions. This growing threat to civil aviation can compromise the accuracy and reliability of aircraft positioning and navigation systems. Recommendations included improved guidance for pilots, better information sharing, and the development of more resilient aircraft systems. There was also broad agreement on the need for a global contingency plan to manage GNSS outages and ensure continued safe navigation.

Operational efficiencies and future-ready systems

The conference established frameworks for the near-term implementation of new procedures on a wider and more consistent scale. These include a specific projects on longitudinal aircraft separation which will safely reduce the distance between aircraft on the same flight path, and free route airspace - a concept allowing more flexible, efficient flight paths between destinations. These initiatives are set to enhance air traffic management worldwide, offering significant performance improvements and operational efficiencies. Additionally, delegates addressed the phasing out of legacy systems, particularly in favor of a more advanced flight planning mechanism, with a targeted global transition by 2034.

Clear direction for necessary steps for trajectory-based operations and the hyper-connected air navigation system was another key outcome of the event. These efforts collectively demonstrate the global aviation community's proactive approach to embracing change and driving progress.
