N806MQ

This airframe, registered as N806MQ, is a 2006-built Gulfstream GIV‑X (G450) with serial number 4059. It is registered in the United States and is recorded as owned by SOUTHERN CROSS AIRCRAFT LLC, a corporate owner based in Fort Lauderdale, FL, which also serves as the aircraft's primary operator/home base. Registry entries for this airframe note a 22‑seat certification, and public valuation or detailed condition reports for this specific airframe are Not published.

The cabin configuration for this airframe follows Gulfstream GIV‑X norms, with typical executive three‑zone layouts of 12–16 places counterposed by the registry listing a 22‑seat certification for this specific ship. Avionics fit on the model are commonly the Honeywell Primus Epic (PlaneView) suite with optional HUD/EVS capabilities, and this airframe is reported with that typical fitment. Operationally the combination of a 4,350 nm range and a 459‑kt cruise speed positions N806MQ for long‑haul corporate missions, including transcontinental and transoceanic flights from its Fort Lauderdale base. Maintenance considerations center on the twin Rolls‑Royce TAY 611‑8C powerplants and associated support programs typical for the type.

The Gulfstream GIV‑X (G450) line occupies a long‑range, high‑speed large‑cabin niche, offering transcontinental and intercontinental capability with a 45,000 ft service ceiling and robust cruise performance. Buyer and charter demand for GIV‑X/G450 airframes often reflects cabin size, avionics standardization (Honeywell Primus Epic/PlaneView) and engine program status; those factors will similarly influence resale prospects for N806MQ. Maintenance and resale considerations for this airframe will hinge on the condition and support status of its Rolls‑Royce TAY engines and the completeness of its typical avionics options.
