Beechcraft King Air 360 Er vs Bell 525 Relentless vs Embraer Legacy 650 E vs Leonardo Aw189

The Beechcraft King Air 360ER is a twin‑turboprop fixed‑wing aircraft typically used for business and special‑mission roles; it trades jet speed for short‑field flexibility and efficiency, with a long range for its class (roughly 1,500–1,800 nm depending on load) and usually carries about 6–9 passengers in executive layouts. The Bell 525 Relentless is a large twin‑engine helicopter aimed at offshore and VIP transport; its practical range is generally around 500–600 nm, and it commonly seats around 12–16 passengers depending on configuration. The Embraer Legacy 650E is a large‑cabin business jet built for long nonstop legs; it offers the longest range of the group at about 3,900–4,000 nm and typically accommodates about 13 passengers in an executive cabin. The Leonardo AW189 is a super‑medium twin helicopter optimized for offshore and utility work; it has range broadly similar to the Bell 525 (often about 450–550 nm) and typically carries about 16–19 passengers in high‑density layouts, fewer in VIP fit.
