Gulfstream G400 vs Gulfstream G500 vs Pilatus Pc 24

The Gulfstream G400 and G500 are large-cabin, long-range business jets, while the Pilatus PC-24 is a smaller, versatile “light-to-midsize” jet optimized for flexibility and shorter missions. In category, the G500 sits above the G400 within Gulfstream’s lineup, offering a larger-cabin, higher-end long-range capability; the G400 is also a large-cabin aircraft but generally positioned slightly below the G500 in overall capability. The PC-24 competes in a different space, emphasizing operational access to shorter runways and more remote airports rather than maximum intercontinental range. For range, the G500 typically provides the longest reach (around 5,300 nautical miles), the G400 somewhat less but still long-range (about 4,200 nautical miles), and the PC-24 substantially shorter (roughly 2,000 nautical miles, depending on load and conditions). Passenger capacity follows a similar pattern: the G400 and G500 commonly seat about 12 to 19 passengers depending on configuration, whereas the PC-24 is usually arranged for about 6 to 10 passengers, with higher-density layouts possible.
