Ten new fuel saving initiatives are being adopted by Wizz Air as part of ongoing efforts to cut carbon emissions by a further 33% by 2030.
The budget airline has already implemented 25 fuel saving measures over the past few years.
The eastern and central European carrier is now focusing on new solutions with its fleet of Airbus A320s.
These include developing a model for estimating zero fuel weight, removing unnecessary extra fuel through the optimisation of flight planning and the introduction of more precise performance factors for accurate fuel burn predictions.
Wizz Air claims to be an industry frontrunner in the use of reduced wing flaps for landing and plans further “operational optimisations in flap configuration”.
Pilots are encouraged to use reduced flap configurations to cut fuel burn for both take-off and landing, resulting in “considerable savings” in fuel consumption.
The lower the flap setting during ascent and descent, the lower the drag, resulting in less fuel burnt, according to the airline.
Statistics on reduced flap landings estimate 2,000 tonnes of fuel saved, eliminating about 6,000 tonnes of carbon dioxide a year from the air.
“Taking into account flight conditions and safety margins, reducing flaps for landing use saves around 15kg of fuel per approach,” Wizz Air said.
“Over a year, this would mean creating savings of carbon dioxide equivalent to 92,300 cars driving from London to Edinburgh.”
Chief operations officer Heiko Holm said: “We are proud to have the lowest CO2 emissions per passenger/kilometre amongst European airlines and are committed to reducing our environmental footprint further.
“Every take-off and landing is an opportunity to save fuel and every flight phase is reviewed for the smallest optimisation, having a significant impact on carbon emissions.
“Together with our modern fleet and maximisation of passenger load factor, we are ensuring that Wizz, the greenest airline in Europe, is the best choice passengers can make when they fly.”
