It also generally seats four (pilot plus three passengers) and tends to offer a comparable or sometimes better practical range than many small turbines, again typically in the few-hundred‑mile class depending on loading and fuel. The Robinson R66 is a light, single‑engine turbine helicopter positioned between the R44 and larger turbines. It commonly seats five (pilot plus four passengers) and typically provides a range in the few-hundred‑mile class, often competitive with or better than small turbines, depending on configuration and reserves.
