Beechcraft King Air 360 Er vs Enstrom 480b vs Piper M600 Sls vs Sikorsky S 92

The Beechcraft King Air 360ER and Piper M600 SLS are pressurized fixed‑wing turboprops, while the Enstrom 480B and Sikorsky S‑92 are helicopters, with the S‑92 being a large, transport‑class twin. In range, the King Air 360ER generally leads this group among turboprops, offering long legs suited to regional and multi‑stop mission profiles. The Piper M600 SLS is also long‑range for a single‑engine turboprop but typically shorter‑legged than the 360ER, optimized for owner‑pilot efficiency. Helicopters trade cruise efficiency for vertical lift; the Enstrom 480B is a light single with comparatively limited range, best for short hops and local utility. The Sikorsky S‑92 has substantial helicopter range for offshore and SAR-style missions, but it still typically falls short of long‑range fixed‑wing turboprops on fuel‑for‑miles efficiency. For passenger capacity, the Enstrom 480B is small (typically a handful of occupants), the Piper M600 SLS is usually configured for about five to six seats, the King Air 360ER commonly carries roughly seven to nine passengers, and the S‑92 carries the most, often configured for around 18–19.
