ToR RMT.0733

Environmental protection requirements for supersonic transport aeroplanes

The objective of this RMT is to maintain a high level of environmental protection in the Union in view of a new generation of supersonic transport (SST) aeroplanes that is currently under development.

To that end, EASA will develop under this RMT environmental protection requirements for SST aeroplanes, including landing-and-take-off (LTO) noise requirements and CO2 emission requirements. Operational requirements for SST aeroplanes including for the purpose of en route noise mitigation are dealt with in RMT.0476 ‘Regular update of the standardised European rules of the air’.

In the absence of adequate environmental protection standards in the International Civil Aviation Organization (ICAO) Standards and Recommended Practices (SARPs) for the areas mentioned above, as per Article 9(2) of Regulation (EU) 2018/1139, the definition of environmental protection certification requirements for SST will be based on the essential requirements for environmental compatibility set out in Annex III to that Regulation.
