Enstrom 480b vs Leonardo Aw189 vs Sikorsky S 92

The Enstrom 480B is a light, single‑engine piston helicopter typically used for training, patrol, and utility work. It sits in a very different category from the other two aircraft, with a comparatively short range and a small cabin. In practical terms it is usually configured for about four occupants total (pilot plus a few passengers), making it suitable for small crews and short missions rather than transport at scale. The Agusta/Leonardo AW189 is a modern super‑medium, twin‑engine helicopter aimed at offshore, SAR, and executive/VIP transport. It offers substantially greater range than the Enstrom and a much larger cabin, commonly seating in the mid‑teens (often around 16–19 passengers depending on layout), enabling meaningful personnel transport over medium distances. The Sikorsky S‑92 is a heavy, twin‑engine helicopter widely used for offshore and government missions. Compared with the AW189 it generally provides similar or greater mission endurance and payload flexibility, with typical passenger seating also in the high‑teens (often around 19), making it best suited to longer-range, higher-capacity transport.
