Leonardo Aw109 Grand New vs Leonardo Aw139 vs Sikorsky S 76d

The Leonardo AW109 Grand New is a light twin-engine helicopter category, typically chosen for short to medium missions; it offers the shortest range of the three (roughly in the 500–600 nautical mile class, depending on configuration) and usually seats about 6–7 passengers in a comfortable executive layout (up to around 8 in higher-density setups). The Leonardo AW139 is a medium twin category aircraft, designed for longer legs and heavier loads; it generally provides the greatest practical range among these three (often around the 600–700+ nautical mile class with appropriate tanks/reserves assumptions) and commonly carries about 8–12 passengers depending on interior and mission fit. The Sikorsky S‑76D sits between them as a light–medium twin; its range is typically comparable to, or slightly below, the AW109 on some profiles but often in the same broad 500–600 nautical mile class, while offering a larger cabin than the AW109 with common seating around 8 passengers (and higher in utility layouts). Actual figures vary materially with payload, fuel options, reserves, and cabin configuration.
