Beechcraft King Air 360 Er vs Bell 525 Relentless vs Pilatus Pc 24 vs Piper M600 Sls

The Beechcraft King Air 360ER is a twin‑engine turboprop business aircraft optimized for runway flexibility and endurance; it offers the longest range of this group at roughly 1,800–1,900 nm and typically carries about 6–9 passengers, depending on interior configuration. The Bell 525 Relentless is a large, fly‑by‑wire commercial/business helicopter; its range is shorter than the fixed‑wing aircraft at roughly 500–600 nm, but it can move about 12–16 passengers (highly configuration‑dependent) and excels where vertical access matters. The Pilatus PC‑24 is a twin‑engine light jet aimed at “jet speed with utility” operations; it typically offers around 1,700–2,000 nm range and commonly seats 6–10 passengers, with a comparatively spacious cabin and strong short/rough‑field capability for a jet. The Piper M600 SLS is a single‑engine turboprop personal/business aircraft; it generally has about 1,400–1,500 nm range and usually carries 1–5 passengers (up to 6 seats including the pilot), trading capacity and redundancy for lower operating complexity.
