Airbus and Delta deploy Descent Profile Optimisation (DSO) across 270-aircraft fleet to cut fuel burn and emissions
Airbus has rolled out Descent Profile Optimisation (DPO/DSO) across Delta’s Airbus fleet of 270 aircraft, spanning A319/A320/A321 and A330 families. The system targets smarter, more efficient descent profiles, with expected reductions in fuel burn and operating emissions, alongside lower operating costs.
