Airbus Helicopters H225 vs Beechcraft King Air 360 Er vs Piper M600 Sls vs Robinson R66

The Airbus H225 and Robinson R66 are helicopters, while the Beechcraft King Air 360ER and Piper M600 SLS are fixed‑wing turboprops. In category and mission, the H225 is a heavy, twin‑engine, long‑range utility/offshore helicopter designed for demanding transport roles; the R66 is a light, single‑engine helicopter aimed at shorter missions with lower operating complexity. The King Air 360ER is a twin‑engine, pressurized business/utility aircraft optimized for longer legs and higher cruise efficiency; the M600 SLS is a single‑engine, pressurized personal/business aircraft emphasizing owner‑pilot operation and advanced avionics. For range, the King Air 360ER generally leads among these, offering the longest endurance of the group. The H225 also provides substantial helicopter range for its class, typically longer than the R66. The M600 SLS offers strong range for a single‑engine turboprop, usually less than the 360ER but more than most light helicopters; the R66 is typically the shortest‑range option. For passenger capacity, the H225 carries the most, commonly configured for well over a dozen passengers. The King Air 360ER typically seats around 6 to 11 depending on configuration. The M600 SLS generally carries up to about 5 passengers plus a pilot, while the R66 is typically limited to about 4 passengers plus a pilot.
