KGOur young fleet consists of Airbus A320 aircraft for short-haul flights and A330s for long-haul routes, all of which are fully-compliant with emission standards set by the International Civil Aviation Organisation, a global standard-setter for the industry. The average age of the fleet is only six years.In 2012, we became the first airline to take delivery of A320s that feature Sharklets, winglets which can lower an aircraft’s fuel burn (and therefore emissions) by lowering air resistance, or drag (see figure 1). With these aircraft, we save up to 4 per cent of fuel or 464kg of CO2 on every flight. AirAsia was also one of the first airlines in the world to fly the Airbus A320neo aircraft with engines by CFM, an engine-maker partly-owned by GE. These state-of-the-art engines further reduce our fuel burn by 16-20 per cent, enabling us to save up to 666 litres of fuel per flight. Lastly, we look to fuel savings by redesigning flight operations. With our partners GE we have developed innovative ways to lower fuel consumption even further. One-engine taxi procedures apply after landing and before take-off. When taxiing out, the second engine is switched on before the aircraft reaches the runway and is about to take off. Conversely, one engine is switched off after landing. This initiative saves us about 9 litres of fuel per flight and 28kg of CO2 while also reducing engine maintenance costs and noise pollution. We have spent over US$40 million to develop more efficient flight procedures for approach and landing at all 14 airports that we fly to in Malaysia and four each in Thailand and the Philippines. Instead of relying on ground-based equipment, Performance Based Navigation (PBN) makes use of the aircraft’s own ability to navigate the shortest possible flight path after take-off or for landing (see figure 2).
