Enstrom 480b vs Robinson R66 vs Sikorsky S 92

The Enstrom 480B and Robinson R66 are light helicopters aimed at utility, training, and short-to-medium missions, while the Sikorsky S‑92 is a large, transport-category helicopter designed for offshore, SAR, and airline-style operations. In range, the 480B and R66 typically operate in the few-hundred–nautical-mile class depending on fuel reserves and conditions, with the R66 often offering somewhat longer practical legs than the 480B in many configurations. The S‑92 generally provides a substantially greater operational radius and endurance than either light helicopter, supporting longer overwater or remote-area sorties with higher payload. Passenger capacity is where the separation is most pronounced: the 480B is commonly arranged for a pilot plus around four passengers; the R66 is typically a five-seat aircraft (pilot plus four), though some configurations can differ. The S‑92, by contrast, is built to carry a much larger cabin load, commonly around 19 passengers (plus crew) in offshore transport layouts, reflecting its higher gross weight, twin-engine redundancy, and mission equipment options.
