With the completion of a fleetwide retrofit, all easyJet aircraft now have Airbus’ Descent Profile Optimisation (DPO) state-of-the-art technology. DPO is a fuel-saving initiative that updates the Flight Management System (FMS) to enable consistently more efficient descents by allowing the aircraft to remain in the cruise phase longer and removing the ‘"level-off" stage at the bottom of the descent. The result is reduced carbon emissions.
For newer aircraft in the easyJet fleet, Continuous Descent Approach (CDA) works alongside DPO to reduce noise.
The multi-million-pound retrofit program, announced last year, is an integral part of the airline’s roadmap to reach net-zero by 2050. It will help easyJet achieve considerable and permanent carbon emission reductions in the short-term by enabling more optimized descent trajectories.
As well as saving on fuel burn and ultimately enabling carbon reductions – DPO along with CDA will help minimize, noise which not only benefits the airline and its customers but also the airports and surrounding communities as a result of tighter noise regulations that are starting to be enforced.
Commenting on the completion of the DPO and CDA retrofit program, Capt. David Morgan, Chief Operating Officer at easyJet, said: “While this is one initiative of many outlined in our roadmap to net-zero, it provides a permanent CO2 saving and forms another step on the way to us realizing our net-zero target.
“While technologies like DPO and CDA are the best solution for more optimized descent trajectories in the here and now – more needs to be done by governments and policymakers to ensure that our airspace is modernized, including implementing Single European Sky, so that this state-of-the-art technology can be used to its full potential.”
Nicholas Chretien, Senior Vice President of Sustainability & Environment at Airbus added: "Airbus is happy to accompany easyJet in its decarbonization journey. Thanks to Airbus technologies, easyJet seamlessly upgraded their fleet with Descent Profile Optimisation; illustrating our ambition to work with our airline partners. These innovative solutions developed at Airbus enable airlines to increase fuel savings and reduce emissions during operations."
easyJet continues to work with stakeholders and public authorities across Europe to advocate for the modernization of airspace, including projects such as the Single European Sky and the UK’s airspace modernization program. For example, the Single European Sky has stated an ambition to deliver 10% carbon emissions savings from European aviation.
easyJet is also one of the founding members of the Single European Sky ATM Research (SESAR) 3 Joint Undertaking, an institutionalised European public-private partnership, to accelerate the delivery of the Digital European Sky.
easyJet was also the first airline evaluation partner for IRIS, a air traffic management program, led by global satellite communications leader Inmarsat, together with the European Space Agency and Airbus, that is set to pave the way for more efficient air traffic management by enabling systems that minimize flight delays, save fuel and help reduce the environmental impact of air travel.
