Dassault Falcon 900lx vs Gulfstream G400 vs Gulfstream G500

The Dassault Falcon 900LX is typically grouped as a long-range, large-cabin tri-jet business aircraft. It is known for intercontinental reach at about 4,750 nautical miles and commonly seats around 12–14 passengers in executive configurations (with certified maximums varying by layout). The Gulfstream G400 sits in the large-cabin, long-range segment but below the G500 in size and reach. It is generally positioned for transcontinental-to-near-intercontinental missions at roughly 4,200 nautical miles and is typically configured for about 10–12 passengers. The Gulfstream G500 is a newer-generation large-cabin, long-range jet positioned above the G400, with a longer published range around 5,300 nautical miles and typical seating about 12–14 passengers depending on cabin arrangement. In short, the G400 is the shorter-range, slightly smaller-cabin option; the Falcon 900LX offers strong long-range capability with three engines; and the G500 leads on range among these three while staying in the same broad large-cabin category.
