easyJet to Upgrade Operations with Descent Profile Optimisation and Continuous Descent Approach | NewsBusteasyJet to Upgrade Operations with Descent Profile Optimisation and Continuous Descent Approach | NewsBust
(27/09/22) easyJet has unveiled plans to upgrade its A320
Family fleet with Airbus’ “Descent Profile Optimisation” (DPO) – a
fuel-saving enhancement to the aircraft’s on-board Flight
Management System (FMS) performance database and “Continuous
Descent Approach” (CDA) to reduce noise impact on the ground.
short-haul airline will become the biggest operator
worldwide to use these powerful combined solutions.
“While our ultimate ambition is to achieve zero
carbon emission flying, we must continue our focus on reducing the
carbon emissions in our operation each and every day. That’s why
this multi-million-pound investment is an important step in
achieving a permanent reduction in the short-term which will see
us operating the largest fleet of DPO and CDA enabled aircraft in
the world,” said Captain David Morgan, easyJet’s interim COO. “But one crucial element to reduce carbon emissions
right now cannot be achieved by the industry alone, and so we are
also calling on governments to introduce airspace modernisation
right now, including finally implementing the Single European
easyJet Airbus A320neo
The DPO and CDA functions allow aircraft to
descend from cruise altitude using only idle engine thrust. This
reduces fuel consumption and associated CO2 and NOx (nitrogen
oxide emissions) reductions as well as noise.
enhance fuel reduction and noise impact, DPO and CDA maximise the
time spent at efficient cruise level by not starting the descent
too early and removing the ‘level-off’ stage at the bottom of the
descent when the aircraft’s engines generate thrust to maintain
level flight in dense air prior to final landing approach.
Following the upgrade, which will be in place by
the end of 2023, easyJet’s entire fleet, of more than 300 Airbus
A320-Family aircraft, will be equipped with DPO and additionally
CDA for compatible aircraft.
“We are very pleased that easyJet will equip its
entire Airbus A320-family-fleet with these state-of-the-art
technologies. Emission reduction in aviation is most successfully
achieved as a team effort – aircraft manufacturers joining forces
with airlines and air traffic management. By combining the use of
DPO and CDA, easyJet will further reduce its fuel consumption
while optimising the trajectory of all its flights,” said Wouter
Van Wersch, Executive Vice President, Region and Sales Europe.
Optimisation of the aircraft’s flight trajectory
is one of the key factors to further improve efficiency in
cooperation with Air Traffic Control.
By optimising the descent
trajectories of its aircraft and reducing the fuel flow to the
engines arising from the lowest ‘idle’ thrust setting during the
descent phase, thanks to the DPO and CDA functions, easyJet will
save more than 98,000 kg of fuel per year per aircraft across its
network in Europe.
That will reduce CO2 emissions by over 311 tons
per year per aircraft, or 88,600 tons of CO2 each year for the
entire A320 Family fleet, representing a significant contribution
to more sustainable flight operations.
