22,000 - 33,000 POUNDS THRUST
Engine Overview
The CFM56-5B 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.
More than 4,000 CFM56-5B engines are in service and have accumulated 50 million flight hours. All CFM56-5B engines delivered since Sept. 2007 are built in the Tech Insertion configuration. This upgrade provides operators with a 1 percent improvement in fuel consumption over the life of the product compared to the base CFM56-5B engine, also leading to lower C02 emissions. Tech Insertion engines also feature a better combustor that emits 25 percent less NOx. As a result, the current production CFM56-5B meets the latest CAEP/6 standards for engines.
