Stage 5 Airplane Noise Standards

The FAA is adopting a new noise standard for certain newly certificated subsonic jet airplanes and subsonic transport category large airplanes. This noise standard, known as Stage 5, applies to any person submitting an application for a new airplane type design with a maximum certificated takeoff weight of 121,254 pounds (55,000 kg) or more on or after December 31, 2017; or with maximum certificated takeoff weight of less than 121,254 pounds (55,000 kg) on or after December 31, 2020. This change will set a lower noise limit for newly certificated airplanes and harmonize the noise certification standards for those airplanes certificated in the United States with those certificated under international standards.
