The CFM56 burns less fuel over an aircraft's life cycle

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 toward 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 LEAP-X program to develop technologies that will enable dramatic fuel efficiency gains by 2015.
