On course for a quieter Heathrow expansion

Recent reports show planes are already around 50% quieter today than they were 10 years ago and 75% quieter than the first generation of jet aircraft. Latest engine models from companies such as Pratt & Whitney, for example, reportedly produce a 50-75% reduction in engine noise compared to current models and an expected 16-20% better fuel burn. This has clear implications for noise pollution and property prices in densely populated metropolitan areas, including most of West London under Heathrow’s flight path. The reduced sound from such engines could also have significant consequences on airport capacity. For instance, planes could potentially fly in and out through the night (some noisier planes are restricted in their flight times), which in turn could result in more available flights.
