Beechcraft King Air 360 Er vs Cessna 208b Grand Caravan Ex vs Leonardo Aw189 vs Sikorsky S 92

The Beechcraft King Air 360ER and the Cessna 208B Grand Caravan EX are fixed‑wing turboprops, while the Leonardo AW189 and Sikorsky S‑92 are medium twin‑engine helicopters. In category, the King Air 360ER is a pressurized, faster business/utility turboprop suited to longer point‑to‑point trips, whereas the Grand Caravan EX is a rugged single‑engine utility aircraft optimized for short/rough-field operations and simpler logistics. The AW189 and S‑92 are offshore/utility helicopters designed for vertical lift missions, with the S‑92 generally positioned as the larger, heavier offshore transport. On range, the King Air 360ER typically offers the longest fixed‑wing endurance among these, often around 1,500–1,800 nautical miles depending on load, while the Grand Caravan EX is usually closer to roughly 800–1,000 nautical miles. The AW189 commonly ranges around 450–500+ nautical miles, and the S‑92 is in a similar offshore-oriented bracket, often roughly 500+ nautical miles, both varying significantly with payload and reserves. On passenger capacity, the King Air 360ER commonly seats about 8–11, the Grand Caravan EX about 9–14, the AW189 typically around 16–19, and the S‑92 about 19 (often up to around 22 in high-density layouts).
