The Pratt&Whitney PW4000-112 engine is destined for the twin-engine Boeing B777 aircraft.
The advanced technologies used such as the turbine with “single-crystal” airfoils and disks in Direct Metal Laser Sintering (DMLS), improved FADEC, and the new TALON (Technology for Advanced Low NOx) technology for the combustor, have contributed to reliability and range, guaranteed optimised fuel consumption and reduction in emissions.
Avio, partner of Pratt&Whitney, is responsible for the production and supply of spare parts for the Accessory Drive Train and Oil Tank.
The PW4000-112 is a twin-shaft turbofan engine with a high-dilution ratio.
It is equipped with a Full Authority Digital Electronic Control (FADEC) system.

| Max Power at SL | 74.000 - 90.000 lb |
| Fan diameter | 112 inches |
| Overall pressure ratio | 34.2 - 42.8 |
