The aircraft’s registry-recorded seating of 22 versus typical outfitting of 12–16 affects valuation and mission flexibility; higher-seat registries can reflect certification choices or corporate specifications. At an indicated value of $11,500,000, resale and charter demand for this airframe will be influenced by avionics fit, engine hours on the Rolls‑Royce Tay Mk 611‑8C pair, and the chosen interior layout and galley configuration.
