EASA has published what it says are the world’s first proposed noise certification standards for eVTOL aircraft. The proposals, known as the Environmental Protection Technical Specifications (EPTS), are applicable to eVTOL vehicles powered by multiple vertical, non-tilting, evenly distributed rotors.
According to the European aviation regulator, the proposed specifications are intended to fill a regulatory gap and use the internationally harmonized noise certification standards for heavy helicopters as a starting point while it “collects more noise data from specific eVTOL designs through certification projects.” In addition, a hover noise level has been developed to aid in the assessment of flight operations in the vicinity of vertiports.
