This report presents the results of a study that was undertaken at Heathrow between June 2018 and March 2019 to monitor the noise performance of aircraft in relation to their QC classifications. Operational noise levels, measured in EPNdB at locations equivalent to the ICAO noise certification measurement positions, were acquired and analysed for a large range of aircraft types.
For the majority of aircraft types monitored, including new aircraft designs such as the Airbus A350 and Boeing 787, the operational noise levels correlated well with the QC classifications. However, large differences between the operational noise levels and the QC classifications were observed for some aircraft types.
