N477FX

This article describes the specific Gulfstream airframe N477FX, a 2008-built Gulfstream G450 with serial number 4118. The airframe is owned by FLEXJET LLC, an LLC based in Cleveland, OH, US, and is registered in the United States as part of FLEXJET's fractional and charter fleet. Registry and valuation records list the airframe with an estimated market value of $11,495,000, reflecting its condition and configuration at the time of valuation. The airframe's operator base and registry actions are tied to its ownership by FLEXJET and its U.S. registration.

The airframe carries a formal certification for a 22-seat configuration, while in practice it is commonly outfitted in 12–14 passenger executive layouts with options for forward and/or aft galley installs, providing FLEXJET flexibility between high-density and executive missions. Avionics are fitted with a Honeywell Primus Epic / PlaneView-class cockpit, with PlaneView options available, supporting modern avionics capability for long-range operations. Typical mission profiles for this airframe leverage its 4,350 nm range and 459 kts cruise speed to operate transcontinental and intercontinental business charters from the operator’s Cleveland, OH base. Maintenance considerations for this specific aircraft include service and overhaul cycles for its twin Rolls-Royce Tay Mk 611-8C engines and adherence to operator maintenance programs consistent with fractional/charter usage.

As a member of the Gulfstream G450 family, N477FX represents the platform’s blend of long-range capability, high cruise speed, and large-cabin flexibility, demonstrated by its 4,350 nm range, 459 kts cruise, and 45,000 ft ceiling. Market interest for such airframes is influenced by certified seating capacity (registered 22-seat), common executive reconfigurations (12–14 passengers), and avionics pedigree (Honeywell Primus Epic / PlaneView-class). Resale and maintenance considerations for this airframe are centered on engine lifecycle and avionics configuration, both of which factor into the listed valuation of $11,495,000.
