A technological LEAP forward
The LEAP® engine was developed by Safran Aircraft Engines and GE through their joint company, CFM International, to power the next generation of single-aisle commercial jets. Combining the best technologies from the two partners, LEAP offers operators exceptional performance while retaining the legendary reliability of the CFM56®. These capabilities have already made the engine a best seller, even before it has entered revenue service.
LEAP-1A: chosen to power the Airbus A320neo
The LEAP-1A® is the airlines' engine of choice for the next-generation single-aisle airliner from Airbus, the A320neo. It offers A320 operators exceptional technical, economic and environmental performance, with a 15% reduction in fuel consumption and CO2 emissions versus current engines, up to 50% margin on NOx emissions versus CAEP/6 Standard, and in compliance with the most stringent noise standards (the ICAO's Chapter 14 regulations).
Selected by the European planemaker Airbus in 2010, the LEAP-1A achieved joint EASA/FAA certification in 2015, and is scheduled to enter service on the A320neo in 2016.
