Model & Market Context
This airframe, registered as N479FX, is a 2008-built Gulfstream G450 with serial number 4139. The aircraft was manufactured by Gulfstream Aerospace and is owned by FLEXJET LLC, a corporation based in Cleveland, OH, US, which operates it as part of a fractional and charter fleet. It carries a United States registration and an estimated market valuation of $11,000,000. No additional public registry actions or transfers are provided for this specific airframe in the supplied data.
The cabin for this particular G450 is described as a typical executive layout accommodating 12–16 passengers in standard configurations, though the airframe is certificated to support up to 22 seats depending on operator configuration and certification choices; FLEXJET’s operation may vary cabin fit to match fractional-use and charter missions. This aircraft is equipped with Gulfstream’s PlaneView II avionics suite, supporting advanced flight management, situational awareness, and integrated systems monitoring commonly used in high-utilization fleets. Typical mission profiles for this airframe under its operator include transcontinental and transoceanic point-to-point charters and fractional-owner travel within the G450’s roughly 4,350 nm range at an average cruise of 459 kts. Operator maintenance considerations for a 2008-built G450 in a fractional fleet setting would focus on keeping avionics and engines compliant with Gulfstream service intervals and managing interior refurbishments to meet client expectations.
The Gulfstream G450 occupies the large-cabin, long-range business jet niche, offering a blend of high cruise speed, transcontinental range, and a 45,000 ft service ceiling that enables efficient routing and favorable fuel-burn profiles for its class. Competing models typically include late-model offerings from Bombardier’s Challenger series and Dassault’s Falcon series; buyers and charter operators value the G450 for its reliability and cabin comfort relative to lifecycle costs. Resale and maintenance considerations for a 2008 G450 such as N479FX include engine TBO planning for the TAY 611-8C powerplants, avionics lifecycle (PlaneView II modernization potential), and interior refurbishment to preserve market value near the cited $11,000,000 estimate.
