Beechcraft King Air 360 Er vs Leonardo Aw189 vs Piper M600 Sls vs Sikorsky S 92

The Beechcraft King Air 360ER and Piper M600 SLS are pressurized fixed‑wing turboprops, while the Leonardo AW189 and Sikorsky S‑92 are twin‑engine medium helicopters. In range, the King Air 360ER is generally the longest‑legged of the group, typically capable of roughly 1,500–1,800 nautical miles depending on payload and reserves, making it well suited to regional missions. The Piper M600 SLS has shorter reach, usually around 1,000–1,400 nautical miles, but offers efficient single‑pilot operations for lighter loads. The AW189 and S‑92 trade cruise efficiency for vertical lift: the AW189 commonly operates around the 400–500 nautical mile class, while the larger S‑92 is often in a similar to slightly longer band, frequently around 450–600 nautical miles, depending on configuration and offshore reserves. For passenger capacity, the M600 SLS is typically a 1‑pilot plus up to 5‑passenger aircraft. The King Air 360ER commonly carries about 6–9 passengers. The AW189 is often configured around 12–16 passengers, and the S‑92 typically about 16–19 in utility/offshore seating.
