Bell 525 Relentless vs Leonardo Aw169 vs Leonardo Aw189 vs Sikorsky S 76d

The Bell 525 Relentless and Leonardo AW189 sit in the larger “super‑medium” class, generally offering the greatest cabin volume and the longest legs among the four, making them common fits for offshore transport and longer-range corporate missions. The Bell 525 is typically positioned with a long-range profile and a high usable cabin load, while the AW189 is similarly optimized for offshore work with comparable long-range capability depending on tanks and payload. The Leonardo AW169 and Sikorsky S‑76D are smaller, medium/light‑twin category aircraft aimed more at short-to-mid range missions, such as EMS, law enforcement, and corporate shuttle. The AW169 is usually configured for fewer passengers than the 525/AW189 and trades some range and cabin size for lower operating footprint. The S‑76D, a long-established corporate/utility platform, commonly carries a similar passenger count to the AW169 in executive layouts, with range typically in the same broad bracket but usually below the larger super‑mediums. In passenger capacity terms, AW169 and S‑76D are often in the roughly 6–8 passenger executive range (higher in utility), while Bell 525 and AW189 more often support roughly 12–16 depending on configuration.
