Delivering on our promises
LEAP engines have delivered on their on CFM’s performance and reliability commitments and have demonstrated high utilization since entering service in August 2016.
An efficient engine
LEAP engines continue to deliver on our performance commitments, with 15% higher better fuel efficiency, 15% lower carbon emissions, and much lower noise than CFM56 engines previous generation engines. Lower fuel consumption helps operators fly more people, to more places, on less fuel – opening longer routes and growing airlines’ networks.
