Leonardo Aw189 vs Piper M600 Sls vs Sikorsky S 92

The Leonardo (Agusta) AW189 and Sikorsky S-92 are medium twin‑engine helicopters aimed at offshore, SAR, and utility missions, while the Piper M600 SLS is a single‑engine turboprop fixed‑wing aircraft optimized for personal and business travel. In range terms, the M600 SLS typically offers the longest point‑to‑point capability (roughly on the order of 1,000+ nautical miles depending on reserves and load), because fixed‑wing cruise efficiency is higher than rotorcraft. The AW189 and S-92 generally have shorter ranges than the Piper but are designed to lift and loiter, with typical mission radii suited to offshore legs rather than long nonstop travel; among the helicopters, the S-92 is often configured for longer overwater legs than many AW189 layouts, depending on tanks and payload. Passenger capacity differs sharply: the M600 SLS is usually flown with 1 pilot and up to 5 passengers (six seats total), the AW189 commonly seats around 16–19 passengers in high‑density transport configurations, and the larger S-92 is often configured around 19 passengers (with some layouts higher or lower based on role and equipment).
