Enstrom 480b vs Leonardo Aw189 vs Piper M600 Sls vs Sikorsky S 92

The Enstrom 480B is a light single‑engine piston helicopter best suited to training and short utility hops; it typically carries a pilot plus up to four passengers and has the shortest range of this group (generally a few hundred nautical miles depending on reserves and payload). The Piper M600 SLS is a single‑engine turboprop fixed‑wing aircraft in the personal/business category; it usually seats one pilot plus up to five passengers and, as a fixed‑wing design, offers substantially longer range than the 480B, commonly on the order of about 1,000+ nautical miles depending on configuration. The Leonardo AW189 is a super‑medium twin‑engine helicopter aimed at offshore and SAR/EMS missions; it carries roughly 16–19 passengers in typical layouts and delivers medium to long helicopter range (often around the 400–500+ nautical mile class with mission tanks and reserves varying). The Sikorsky S‑92 is a heavier twin‑engine helicopter in the large transport category; it commonly seats about 19 passengers (with higher-density options) and offers comparable or greater mission range than the AW189 depending on fit, frequently in the 500+ nautical mile class.
