Leonardo Aw139 vs Leonardo Aw169 vs Sikorsky S 76d

The Leonardo AW139 is typically positioned as a medium twin helicopter, offering the greatest overall cabin volume of the three and generally the highest passenger capacity in normal configurations. It is often chosen when operators want a more “transport” oriented aircraft with strong payload flexibility and longer legs between fuel stops, so its practical range is commonly viewed as the best of this group depending on fuel fit and mission profile. The Leonardo AW169 sits in the lighter, intermediate twin category between the AW139 and the S-76D. It usually carries fewer passengers than the AW139 but can be configured efficiently for corporate, EMS, and utility roles. Its range is generally competitive but usually a step below the AW139, with performance and cabin size aimed at missions where a slightly smaller, lighter aircraft is preferred. The Sikorsky S-76D is a light-intermediate twin widely used for offshore and executive transport. Passenger capacity is typically comparable to, or slightly below, the AW169 depending on interior fit, and it is generally less than the AW139. Its range is commonly in the same broad class as the AW169, with exact figures varying by payload, reserves, and equipment.
