Airbus Helicopters H175 vs Bell 412epi vs Leonardo Aw139 vs Sikorsky S 76d

All four are twin‑engine civil/utility helicopters, but they sit in slightly different weight and mission classes. The Airbus Helicopters H175 and Leonardo AW139 are generally in the larger “super‑medium” segment, optimized for offshore transport and longer legs; both typically offer the greatest range in this group and commonly carry around 12–16 passengers in offshore-style layouts (higher in high‑density configurations). The Bell 412EPi is a medium twin often favored for utility, public service, and mixed missions; its practical range is usually shorter than the H175/AW139, and typical seating is roughly 10–13 passengers depending on interior. The Sikorsky S‑76D is a lighter, fast twin in the medium/light‑intermediate category, widely used for executive and offshore roles; it generally carries fewer passengers than the H175/AW139 (often about 8–12) and offers competitive but typically mid‑pack range relative to the larger super‑mediums. Exact figures vary notably with fuel, payload, reserves, and interior configuration.
