Enstrom 480b vs Piper M600 Sls vs Robinson R66 vs Sikorsky S 92

The Enstrom 480B and Robinson R66 are light single‑engine helicopters, while the Piper M600 SLS is a single‑engine turboprop airplane, and the Sikorsky S‑92 is a large twin‑engine transport helicopter. In range, the Piper M600 SLS typically leads in real‑world point‑to‑point capability, often around 1,000+ nautical miles depending on reserves and payload, whereas the Enstrom 480B and Robinson R66 are generally in the few‑hundred‑nautical‑mile class for typical missions. The Sikorsky S‑92 can cover substantial distances for a helicopter, commonly several hundred nautical miles, but its range varies widely with passenger load, offshore equipment, and reserves. For passenger capacity, the Enstrom 480B is usually configured for about five seats total, and the Robinson R66 for about five as well. The Piper M600 SLS is typically a six‑seat aircraft (one pilot plus up to five passengers, depending on loading). The Sikorsky S‑92 is in a different league, commonly configured around 19 passengers (plus crew) for airline‑style seating, with other layouts possible.
