This document specifies methods for recording the time history of instantaneous sound pressure in several positions around rotor powered unmanned aircraft systems (UAS) with a maximum take-off mass [9] (MTOM) of less than 150 kg in accordance with ISO 21895 . The UAS can be either electrically powered or fuel-powered. It is not applicable to the tilt-rotor or tilt-wing UAS. It does not account for the UAS noise certification or regulation This document can also be applied to measure the sound pressure from a UAS with either multiple rotors or a single rotor. This document specifies: a) recommendations and requirements for three different test facilities for the noise measurements of various categories of multirotor-powered UAS: — requirements and recommendations of UAS noise tests in anechoic chambers (Clause 7); — requirements and recommendations of UAS noise tests in anechoic wind tunnels (Clause 8); — requirements and recommendations of UAS noise tests in outdoor environments (Clause 9); b) requirements and recommendations for the configuration of noise measurement for multirotor- powered UAS in hover, vertical take-off and landing, and horizontal cruise; c) recommendations for the test configuration and procedures to minimize the influence of meteorological effects.
