FB-5

The Boeing FB‑5 is a twin‑engine, medium‑range business jet that entered service in 1998 after a seven‑year development program that began in 1991. Conceived to bridge the gap between Boeing’s larger commercial airliners and its earlier light‑jet offerings, the FB‑5 incorporated composite wing structures and a fully digital fly‑by‑wire cockpit, making it the first Boeing aircraft to use all‑glass avionics outside of its commercial fleet. Powered by two Garrett TFE‑731‑40 turbofan engines, the jet delivers a maximum cruising speed of Mach 0.78 and a range of 4,500 nautical miles, allowing nonstop trans‑Atlantic flights with a typical four‑passenger configuration. The cabin is pressurized to a cabin altitude of 6,000 feet, and its modular interior can be reconfigured for corporate, medical or utility missions. Throughout its production run of 210 units, the FB‑5 earned a reputation for reliability, low operating costs, and quiet operation, which contributed to its widespread adoption by corporations, government agencies, and air‑ambulance operators. Its introduction influenced subsequent Boeing designs, encouraging the integration of advanced materials and fly‑by‑wire technology across the company's broader portfolio, and it remains a milestone in the evolution of modern business aircraft.
