More efficient aircraft power for cleaner operation

Aircraft operators face the pressing challenges of rising fuel costs and increasing environmental scrutiny. Since an engine’s fuel burn is responsible for the release of CO2, fuel efficiency plays a major environmental, as well as financial, role.

CFM is always making its engines more efficient. Today’s baseline CFM56-7B is 7 percent more fuel efficient than the first CFM56-3 engines flying on the Boeing 737-300.

With the introduction of new Tech Insertion technology, CFM has introduced another increase in fuel efficiency for customers. If an airline were to refit 20 of its aircraft with the latest Tech Insertion engines, it could save nearly US$384,000 in fuel costs annually compared to the base CFM56-5B or -7B engines.
