AirAsia adds software to reduce emissions

AirAsia has announced that it will install an innovative aircraft software modification known as Descent Profile Optimizer (DPO) on its A320ceo aircraft starting in June, on World Airborne Day. environment. This upgrade will help generate fuel savings and significantly reduce carbon dioxide (CO₂) emissions. Improving the Flight Management System (FMS) performance database on board the aircraft allows the aircraft to optimize the descent phase of flight, which subsequently minimizes the time spent an ineffective level.

The new initiative aims to reduce fuel burn and improve fuel efficiency by up to 0.75% of fuel burn, which is equivalent to saving 101 kg of CO₂ emissions per flight. This could reduce CO₂ emissions by more than 221 tonnes per aircraft per year, which is a significant contribution to more sustainable flight operations. When initially installed on 17 aircraft, it would save 3,764 tonnes of CO₂ per year or the equivalent of planting 62,700 urban trees based on the US EPA’s greenhouse gas equivalence calculator.

Bo Lingam, Group CEO of AirAsia Aviation Group Limited (AAAGL), said: “As the travel industry begins to recover and we expect to return to pre-pandemic levels by the end of this year. , it is important that we review our climate strategy. and put in place new mechanisms and processes that will help minimize the environmental impact of our flight operations. Installing the new Flight Operations Optimization solution for our current A320ceo aircraft allows us to reduce our carbon footprint in the short to medium term while continuing to gradually upgrade our fleet to the higher capacity A321neo and more fuel efficient in the longer term. Given the reality of climate change and the airline industry’s contribution to emissions, reducing our carbon footprint is currently one of our top sustainability priorities and we look forward to reducing another 221 tons of additional CO₂ emissions per aircraft every year with the DPO system we’re running. We remain committed to ensuring that we not only build a sustainable airline, but also align with the aviation industry’s sustainability goal to reach net zero by 2050.”

Besides the DPO, AirAsia has implemented several other key efficiency initiatives to reduce fuel consumption and carbon emissions such as One Engine Taxi (procedure to operate one engine during taxi phase of flight instead of both engines), Idle Reverse Landing (a procedure that uses idle engine thrust on landing instead of powered thrust to reduce noise and fuel consumption) and RNP-AR (Required Navigation Performance-Authorization Required) (a procedure that uses the aircraft’s advanced navigation capabilities instead of conventional ground equipment for the shortest landing approach). In 2021, these measures enabled AirAsia to avoid emitting 11,175 tons of carbon dioxide, which is equivalent to planting 186,250 urban trees.
