Airbus Helicopters H125 vs Bell 505 Jetranger X vs Robinson Helicopters R66 Marine

Airbus Helicopters’ H125 is the largest and most capable of the three, typically configured to carry a pilot plus five to six passengers depending on interior and mission equipment. It also offers the longest practical range in this group, commonly in the roughly 330–350 nautical mile class with standard fuel, and it is often chosen when higher useful load, hot-and-high performance, and mission flexibility matter most. The Bell 505 JetRanger X sits in the light single segment with a pilot plus four passengers in a typical arrangement. Its range is generally mid-pack, commonly around the 300 nautical mile class, making it well suited to short-to-medium passenger transport and utility work with a modern avionics suite and relatively low operating footprint. The Robinson R66 Marine is a light turbine five-seat helicopter, usually flown as a pilot plus four passengers. Its range is typically the shortest of the three, often around the 300 nautical mile class or slightly less depending on configuration and reserves. The “Marine” variant emphasizes corrosion protection and maritime suitability rather than maximizing passenger count or range.
