Bell 525 Relentless vs Dassault Falcon 8x vs Piper M600 Sls vs Sikorsky S 92
The Bell 525 Relentless and Sikorsky S‑92 are medium/large twin‑engine helicopters, while the Dassault Falcon 8X is a long‑range business jet and the Piper M600 SLS is a single‑engine turboprop. For range, the Falcon 8X is in a different class, offering true intercontinental capability of roughly 6,450 nautical miles, far beyond the others. The M600 SLS is designed for efficient regional missions, typically around 1,600 nautical miles. The Bell 525 targets offshore, EMS, and corporate rotorcraft missions with a range on the order of the high‑500s to around 600 nautical miles, whereas the larger S‑92 is optimized for offshore transport with a broadly similar helicopter-class range, commonly cited in the 500–600+ nautical mile neighborhood depending on payload and reserves. Passenger capacity also separates them: the Falcon 8X commonly carries about 8–14 passengers in executive layouts; the M600 SLS typically seats up to 6; the Bell 525 is usually configured around 12–16; and the S‑92 is often configured for about 19 passengers (or more in some layouts).
