Airbus Helicopters H155 vs Airbus Helicopters H175 vs Leonardo Aw169 vs Sikorsky S 76d

The Airbus Helicopters H155 is a light–medium twin typically used for corporate and EMS missions; it generally offers a practical range on the order of roughly 450–550 nautical miles and is commonly configured for about 8–12 passengers (with higher-density layouts possible depending on interior and fuel choices). The Leonardo AW169 sits in the light-intermediate class; it usually delivers similar-to-slightly-longer legs in many configurations, often around 400–500+ nautical miles, and typically carries about 8–10 passengers in executive layouts, with higher seating counts in utility roles. The Sikorsky S-76D is a medium twin optimized for offshore and corporate work; typical ranges are often around 400–500 nautical miles, with common passenger loads of about 8–12 depending on fit-out and reserves. The Airbus Helicopters H175 is the largest of the four, in the super-medium segment aimed at offshore and SAR; it generally offers the longest endurance/range capability of this group, often around 500–600+ nautical miles, and commonly seats about 12–16 passengers in transport layouts. Figures vary with payload, fuel, reserves, and cabin configuration.
