Enstrom 480b vs Leonardo Aw189 vs Piaggio Avanti Evo vs Sikorsky S 92

The Enstrom 480B is a light single‑engine piston helicopter suited to short‑range utility and training; it carries a pilot plus a small group (typically up to four passengers) and has the shortest range of the four, generally a few hundred nautical miles depending on reserves and payload. The Agusta/Leonardo AW189 is a modern medium twin helicopter aimed at offshore and SAR missions, offering substantially longer range than the Enstrom and seating commonly in the mid‑teens (high‑capacity layouts can approach around 18–19 passengers). The Piaggio Avanti EVO is a pressurized twin‑turboprop fixed‑wing aircraft in the business/utility category; it is much faster and usually longer‑ranged than the helicopters, typically configured for about seven to nine passengers. The Sikorsky S‑92 is a heavy twin helicopter optimized for offshore transport and SAR, generally carrying a similar or larger passenger load than the AW189 (often up to about 19 in transport layouts) with strong range and payload; compared with the AW189 it is usually positioned as the larger, heavier‑lift option.
