Airbus Helicopters H175 vs Leonardo Aw139 vs Sikorsky S 76d vs Sikorsky S 92

The Airbus Helicopters H175 and Leonardo AW139 sit in the medium twin category, often chosen for offshore transport and corporate/VIP missions. In typical configurations they carry roughly 12–16 passengers, with practical mission ranges commonly in the mid-hundreds of nautical miles depending on payload, reserves, and cabin fit; both can be equipped to stretch range with auxiliary fuel, with the H175 generally positioned toward the higher end of the medium segment. The Sikorsky S-76D is a lighter, smaller twin-engine helicopter optimized for executive transport and EMS. It typically carries about 6–8 passengers (sometimes more in high-density layouts) and usually offers shorter overall range than the H175/AW139 class, though it remains strong for regional point-to-point missions. The Sikorsky S-92 is a heavier, large-cabin twin designed primarily for offshore and SAR/utility roles. It typically carries around 18–19 passengers and offers the greatest payload-and-cabin capability in this group, with range comparable to, and often operationally more robust than, the medium twins when carrying larger passenger loads.
