Beechcraft King Air 360 Er vs Daher Tbm 960 vs Enstrom 480b vs Robinson R66

The Beechcraft King Air 360ER and Daher TBM 960 are pressurized turboprop airplanes, while the Enstrom 480B and Robinson R66 are turbine helicopters. In category and typical mission, the King Air 360ER is a larger, twin‑engine utility/business aircraft suited to longer, more flexible trips and higher payloads; the TBM 960 is a fast, single‑engine business turboprop optimized for efficient point‑to‑point travel with fewer seats. For range, the King Air 360ER generally offers the longest endurance among these four in typical long‑range configuration, the TBM 960 is also long‑range but usually less than the 360ER, and both helicopters have substantially shorter range than either fixed‑wing turboprop. For passenger capacity, the King Air 360ER typically carries the most (commonly up to about nine including pilots, depending on interior and regulations), the TBM 960 is typically six seats total, the Enstrom 480B is usually configured for five seats, and the Robinson R66 is also typically five seats. Overall, the fixed‑wing turboprops dominate range and cruise efficiency, while the helicopters trade range and speed for vertical lift and access.
