The Airports Council International (ACI) has urged the International Civil Aviation Organization (ICAO) to develop supersonic aircraft standards and practices.

Supersonic aircraft is expected to be reintroduced in 2023.

ACI has not yet received evidence from makers that new supersonic aircraft will comply with the latest ICAO standards.

The airport industry is already facing increased pressure from communities to better tackle existing noise levels and emissions footprints.

At the ICAO assembly, ACI presented its Reintroduction of Supersonics paper and invited the assembly to recognise its views on Standards and Recommended Practices.

ACI World director general Angela Gittens said: “Public acceptance of aviation rests on our ability to face the operational and environmental challenges currently posed by noise and emissions from subsonic aircraft. The introduction of supersonic aircraft must not destroy that acceptance.

“In order to be integrated into the commercial aviation ecosystem, supersonic aircraft must not be noisier than comparable subsonic aircraft of the same Maximum Take-Off Mass (MTOM) during their subsonic operations.

“This is a matter which affects the entire aviation industry and it is essential for the development of Standards and Recommended Practices for supersonic aircraft to respond to the industry requirements while also addressing the potential impact on the community, the environment and airport operations.”
