The project was previously known as the Geared Turbofan (GTF), and originally the Advanced Technology Fan Integrator (ATFI). The engine is expected to deliver reductions in fuel use and ground noise when used in next - generation aircraft . The PW1000G engine first entered commercial use in January 2016 with Lufthansa's first commercial Airbus A320neo flight . </P> <P> Pratt & Whitney first attempted to build a geared turbofan starting around 1998, with the PW8000 . This essentially was an upgrade of the existing PW6000 that replaced the fan section with a gearing system and new single - stage fan . After several years of development the PW8000 essentially disappeared . </P>
