Although aircraft operators have struggled with volatile fuel prices over the years, they’ve always been able to depend on one thing: CFM’s steady drive towards lower engine fuel burn.

Over its lifecycle, the CFM56-5B has a fuel burn advantage that surpasses its competitor. This is because CFM’s superior engine design results in lower gate-to-gate fuel burn, better performance retention and a shorter required warm-up time.






Looking forward, CFM knows rising fuel prices will continue to have a major impact on airlines. To meet customer needs, we launched the LEAP56 program to develop technologies that will enable dramatic fuel efficiency gains by 2015.
