Airbus Helicopters H135 vs Bell 407gxi vs Robinson Helicopters R66 vs Sikorsky S 76d

The Airbus Helicopters H135 is a light twin-engine helicopter commonly used for EMS, police, and corporate transport; it typically carries a pilot plus about five to six passengers and offers a moderate range on the order of a few hundred nautical miles, with strong redundancy versus single-engine types. The Bell 407GXi is a light single-engine helicopter aimed at utility and executive missions; it generally seats a pilot plus five to six passengers and has a similar “few hundred nautical mile” class range, often benefiting from strong hot-and-high performance. The Robinson R66 is a lighter, lower-cost single-engine turbine helicopter in a smaller category; it usually carries a pilot plus four passengers and has a somewhat shorter but still comparable regional range, also in the few-hundred-nm band depending on reserves and configuration. The Sikorsky S-76D sits in the medium twin category for offshore and VIP work; it carries more people—commonly two crew plus six to eight passengers—and offers longer legs than the light helicopters, typically toward the upper end of the several-hundred-nm range.
