CFM International CFM56-5

The CFM56-5 is the engine of choice for the A320 family, having been selected to power nearly 60 percent of the A318/A319/A320/A321 aircraft ordered. One of the primary factors behind the CFM56-5B's broad-based market acceptance has been its simple, rugged architecture, which gives it the highest reliability, durability, and repairability in its class. In addition, CFM continually invests in technology enhancements that make the engines even better.

As the only engine that can power every model of the A320 family with one bill of materials, the CFM56-5B provides airlines a distinct commonality advantage, in addition to the lowest cost of operation on this application.

Noise and emissions have become key factors in aircraft fleet planning and operations. The CFM56-5B is the only engine in the A320 family to offer advanced double annular combustor (DAC) technology. The CFM DAC reduces NOx (oxides of nitrogen) emissions by as much as 45 percent. The technology has been so well received in the marketplace that nearly 40 percent of all CFM56-5B-powered A320s in service or on order with European airlines are equipped with this technology.
