Beechcraft King Air 360 Er vs Bell 525 Relentless vs Enstrom 480b vs Sikorsky S 92

The Beechcraft King Air 360ER is a pressurized twin‑turboprop fixed‑wing aircraft aimed at efficient regional missions. It offers the longest range of the group at roughly 1,500 nautical miles and typically carries about 6–9 passengers in an executive layout (higher in commuter configurations). The Bell 525 Relentless and Enstrom 480B are helicopters, but in very different classes. The Bell 525 is a super‑medium twin‑engine helicopter designed for offshore and corporate transport, with a range around 560–600 nautical miles and a typical passenger load around 12–16 depending on configuration. The Enstrom 480B is a light single‑engine helicopter focused on utility and training roles, with a much shorter range (roughly 200–300 nautical miles) and usually seats 4–5 people including the pilot. The Sikorsky S‑92 is a heavy twin‑engine helicopter optimized for offshore and SAR operations, with range typically around 500–600 nautical miles and seating commonly about 19 passengers in transport layouts (or fewer with mission equipment).
