Airbus Helicopters H155 vs Sikorsky S 76d

The Airbus Helicopters H155 and Sikorsky S-76D sit in the medium, twin‑engine civil helicopter category, commonly used for executive transport, offshore support, and EMS roles. The H155 is generally positioned as a slightly larger cabin-class aircraft with a strong emphasis on passenger comfort and mission flexibility, while the S-76D is a well-known premium medium twin often selected for corporate and offshore operations where speed and established support networks are valued. In range, both are broadly comparable for typical missions, with published maximum ranges often landing in a similar band depending on fuel configuration, payload, and reserves; real-world range is frequently driven more by passenger load and weather than brochure figures. For passenger capacity, both are commonly configured around 12 passengers in high-density layouts, though executive interiors usually seat fewer to maximize comfort; the H155’s cabin volume can provide a bit more space for spacious VIP or utility configurations, whereas the S-76D typically offers a refined corporate layout with strong performance consistency across common mission profiles.
