Beechcraft King Air 360 Er vs Bell 525 Relentless vs Leonardo Aw189 vs Pilatus Pc 24

The Beechcraft King Air 360ER and Pilatus PC-24 are fixed‑wing aircraft, while the Bell 525 Relentless and Leonardo AW189 are helicopters. In category, the King Air 360ER is a twin‑turboprop business/utility aircraft optimized for efficient short-to-medium missions; the PC-24 is a light jet designed for faster point-to-point travel and operating from many shorter or less‑improved runways. The Bell 525 is a super‑medium helicopter aimed at high-speed offshore and corporate transport; the AW189 is a medium helicopter widely used for offshore, SAR, and VIP missions. On range, the PC‑24 generally offers the longest reach (roughly around 2,000 nm class depending on load and reserves), the King Air 360ER follows with extended-range turboprop capability (about 1,500+ nm class), and the two helicopters are typically shorter-legged in airplane terms, commonly in the several-hundred‑nautical‑mile range, with the 525 often offering more range than the AW189 in typical configurations. For passenger capacity, the helicopters frequently seat the most in transport layouts (often up to the mid-to-high teens), while typical executive layouts are lower. The King Air 360ER commonly carries about 6–9 passengers in business configuration, and the PC‑24 typically about 6–10 in executive seating.
