Bell 525 Relentless vs Gulfstream G700 vs Piaggio Avanti Evo vs Pilatus Pc 24

The Bell 525 Relentless is a fly-by-wire helicopter aimed at VIP and offshore missions. It typically carries about 12–16 passengers in an executive layout and offers roughly 500–600 nautical miles of range, trading speed and range for vertical-access flexibility. The Gulfstream G700 is an ultra-long-range large-cabin business jet designed for intercontinental travel. It seats around 13–19 passengers in most business configurations (higher-density layouts are possible) and delivers about 7,500 nautical miles of range, making it the clear leader for nonstop global city pairs. The Piaggio Avanti EVO is a high-speed twin-turboprop business aircraft with a quieter, stand-up-style cabin for its class. It generally carries 6–8 passengers and offers approximately 1,400–1,700 nautical miles of range, emphasizing efficiency and short-to-medium trip capability. The Pilatus PC-24 is a light jet optimized for versatility, including operation from shorter and semi-prepared runways. It typically carries 6–10 passengers and provides roughly 2,000 nautical miles of range, sitting between the Avanti and the G700 in reach while prioritizing access to more airports.
