Enstrom 480b vs Leonardo Aw189 vs Piper M600 Sls vs Robinson R66

The Enstrom 480B and Robinson R66 are light, single‑engine helicopters suited to short‑to‑medium missions; both typically carry a pilot plus up to four passengers, with the R66 generally offering longer range and higher cruise speed than the 480B. The Agusta/Leonardo AW189 sits in a very different class: it is a large, twin‑engine, medium helicopter designed for offshore, SAR, and utility work, with far greater payload and cabin volume and typically configured for roughly 16–19 passengers, along with substantially longer range than light helicopters. The Piper M600 SLS is not a helicopter but a single‑engine turboprop airplane; it trades vertical lift for higher cruise efficiency, generally providing longer range and faster point‑to‑point travel than the helicopters here, with seating commonly for one pilot plus up to five passengers. In category terms, the 480B and R66 are light single‑engine rotorcraft, the AW189 is a medium twin rotorcraft, and the M600 SLS is a pressurized single‑engine turboprop fixed‑wing aircraft; in range, the M600 SLS and AW189 typically lead, followed by the R66, then the 480B.
