LATAM Airlines to Save Fuel with Airbus Descent Profile Optimisation Software

LATAM Airlines is to upgrade its fleet of A320 family aircraft with Airbus Descent Profile Optimisation (DPO) function fuel-saving software that can be added to the aircrafts on-board Flight Management System (FMS) performance database.

The upgrade will be performed on over 200 of LATAMs A320 family fleet, becoming the biggest Airbus fleet equipped with the solution.

The DPO installation kits will be delivered from the end of 2021 into early 2022.

The DPO function allows aircraft to descend from cruise altitude using only idle engine thrust, which reduces fuel consumption, bringing proportional CO2 and NOx (nitrogen oxide emissions) reductions.

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 function - LATAM Airlines will generate over 100 tons fuel savings per year per aircraft across their network, including constrained airports like Lima, Santiago and So Paulo.

To further enhance the fuel reduction DPO maximises the time spent at efficient cruise level - by not starting the descent too early - and subsequently minimising the amount of time spent at an inefficient level-off stage at the bottom of the descent when the aircrafts engines generate thrust to maintain level flight in dense air prior to final landing approach.

Optimisation of the aircrafts 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 function - LATAM Airlines will generate over 100 tons fuel savings per year per aircraft across their network, including constrained airports like Lima, Santiago and So Paulo.

This will reduce CO2 emissions by over 300 tons per year per aircraft, representing a significant contribution to more sustainable flight operations with 60,000 tons of CO2 each year for the entire LATAM Airlines A320 Family fleet.
