Local air quality and noise

Local air quality

Local air quality impact arises from nitrogen oxides (NOx) emissions during aircraft take-offs and landings. easyJet’s new engines feature a tech insertion which reduces NOx emissions by around 25%. These are in use in 67.8% of easyJet’s aircraft.

Noise

easyJet wants to be a good neighbour in the communities around the airports where it operates and the impact of aircraft noise on residents is an important consideration. We comply with local rules that govern noise at airports (such as curfews and routings to avoid built-up areas).

easyJet aircraft meet the tightest international noise standards (ICAO Chapter 4). We also work locally with airports and air traffic control to put in place noise mitigation activities that best fit each airport.

Our work to improve the efficiency of flying has also reduced the noise impact. For example, a change in the flap settings used for landings has improved fuel efficiency and reduced noise levels at landing. At London Gatwick, easyJet’s largest base, the airline is a leader in the use of Continuous Descent Approaches in which aircraft descend more efficiently and quietly.

easyJet has worked to further reduce aircraft noise in response to comments from local residents about the A320 family aircraft of all airlines, particularly at London Gatwick. All new aircraft delivered to easyJet since June 2014 are fitted with ‘vortex generators' to prevent a particular sound due to airflow under the wing. From November 2015 easyJet will begin an engineering programme to modify 197 existing aircraft with vortex generators. It expects to complete the programme by March 2018.
