uel efficiency refers to distance an airplane can travel on one gallon of fuel and how low its carbon emissions are. The available seats on aircraft are expected to grow by around five per cent yearly. The global fleet is expected to grow by 20,930 aircraft to reach about 40,000 by 2032. It is estimated that fuel demand from aviation will
increase around 2.3 per cent annually till 2025. Aircraft manufacturers and airlines are working closely to reduce emissions and fuel consumption through increasing fuel efficiency using new technologies, designs, materials, improving engines, enhancing aerodynamics and using lighter materials. Pratt & Whitney is part of the ‘double-bubble’ D8 design experiment that involves moving SP’S AIRBUZ • Issue 1 • 2022
