Airbus Helicopters H125 vs Bell 505 Jetranger X vs Robinson Helicopters R44 Raven I vs Robinson Helicopters R44 Raven Ii vs Robinson Helicopters R66

The Airbus Helicopters H125 sits in the light single‑engine utility category and is generally used for higher‑performance work; it typically carries the pilot plus about five passengers, and it offers a comparatively strong range for a light single, often in the roughly 350–400+ nautical mile class depending on configuration. The Bell 505 JetRanger X is also a light single‑engine helicopter, usually arranged for the pilot plus four passengers, with a range that commonly falls in a similar general bracket but is often slightly less than an H125 when both are in standard passenger configurations. The Robinson R44 Raven I and Raven II are light, piston‑powered singles; both are four‑seat aircraft (pilot plus three passengers) and are generally shorter‑range than the turbine singles, with typical practical ranges around the low‑to‑mid‑300 nautical mile area depending on tanks and power settings. The R44 Raven II is essentially an updated, higher‑gross‑weight evolution of the Raven I with broadly similar seating and comparable range. The Robinson R66 is a light single‑engine turbine positioned above the R44, typically seating the pilot plus four passengers, with range and payload generally exceeding the R44 series.
