The EASA certification noise levels are approved by EASA as part of the aircraft certification process. These noise levels are established in compliance with the applicable noise standards as defined in ICAO Annex 16, Volume I. They are the basis against which the National Aviation Authorities of EASA Member States issue individual noise certificates to aircraft on their registers using the EASA Form 45.
EASA publishes a database of certification noise levels containing all approved aircraft configurations (see Downloads section below). The database covers: aircraft for which EASA has issued a type certificate data sheet for noise (TCDSN) accessible from the TCDS page; aircraft modifications resulting from acoustically significant supplemental type certificates (STCs); aircraft and aircraft modifications certified by Member States prior to EASA becoming responsible, the so-called “transferred products”. It comprises four distinct files, one for each of the following aircraft categories: jet aeroplanes, heavy propeller-driven aeroplanes, light propeller-driven aeroplanes and rotorcraft.
