AIRCRAFT BRIEF

The Boeing 737-800 is the best-selling variant of the 737 Next Generation family, with nearly 5,000 delivered since its first flight on July 31, 1997. Powered by two CFM56-7B turbofan engines, it replaced older 737 Classics in fleets worldwide and became the backbone of low-cost carriers like Ryanair. The iFly 737-800 is a highly detailed third-party simulation for MSFS 2024, featuring accurate systems depth, a fully functional FMC, and realistic cockpit behavior.
