Bell 412epi vs Leonardo Aw139 vs Sikorsky S 76d

The Bell 412EPi is best categorized as a medium-twin utility helicopter, commonly used for public service, offshore support, and general transport. Its typical passenger capacity is around 10–13 depending on interior fit, and its range is generally in the roughly 350–400 nautical mile class, emphasizing versatility and load-carrying over speed. The Leonardo AW139 sits in the medium twin-engine class but is positioned as a higher-speed, longer-range, multi-mission platform with strong offshore and EMS credentials. It typically carries about 12–15 passengers in transport layouts and usually offers the longest range of the three, commonly around 500–600 nautical miles with standard tanks and reserves, depending on configuration. The Sikorsky S-76D is a medium twin optimized for executive and offshore missions, with a refined cabin and strong cruise performance. It most often seats about 8–12 passengers, and its range is generally comparable to, or slightly below, the AW139 in many typical configurations, often around 400–500 nautical miles.
