Airbus has deployed its Descent Profile Optimisation (DPO) function on Delta Air Lines’ aircraft fleet, enhancing flight management system performance to cut fuel consumption and CO2 emissions. This upgrade optimizes descent trajectories, enabling more efficient engine idle thrust and later top-of-descent points.
DPO updates the onboard Flight Management System (FMS) database, reducing level-off stages without impacting approach speeds. It aligns older aircraft operations with newer neo standards, supporting Delta’s decarbonization efforts amid rising sustainability pressures.
The technology, previously adopted by Air Canada on 48 A320ceo and 18 A330ceo aircraft, delivers measurable savings—up to 70 tons of fuel per A320 annually (220 tons CO2 equivalent) and 110 tons per A330 (340 tons CO2 equivalent). For Delta, it promises similar operational gains across its Airbus fleet, lowering costs and NOx emissions.
This deployment builds on Delta-Airbus collaborations, including predictive maintenance via Skywise and innovation labs targeting fuel efficiency. It strengthens fleet performance in a market demanding net-zero progress by 2050, prioritizing immediate in-service upgrades over new designs.
