Bell 525 Relentless vs Enstrom 480b vs Pilatus Pc 24 vs Sikorsky S 92

The Bell 525 Relentless and Enstrom 480B are helicopters, while the Pilatus PC-24 is a twin‑engine business jet and the Sikorsky S‑92 is a medium, twin‑engine transport helicopter. In range terms, the PC‑24 typically offers the longest legs, commonly around 2,000 nautical miles depending on load and reserves, making it best suited for point‑to‑point regional or transcontinental missions. The Bell 525 and Sikorsky S‑92 sit in the midrange helicopter class, generally in the several-hundred‑nautical‑mile bracket (often roughly 500–600 nm, mission dependent), optimized for offshore, corporate, or utility work where vertical lift matters. The Enstrom 480B is a lighter single‑engine helicopter with a shorter typical range (often a few hundred nautical miles), oriented toward training, patrol, and light utility roles. For passenger capacity, the PC‑24 is usually configured for about 6–10 passengers, the Bell 525 commonly targets around 10–16 seats depending on layout, the S‑92 typically carries roughly 19 passengers in offshore/transport configurations, and the Enstrom 480B is a 4–5 seat aircraft.
