Airbus Helicopters H125 vs Airbus Helicopters H145 vs Bell 505 Jetranger X vs Leonardo Aw139 vs Sikorsky S 76d

The Airbus H125 and Bell 505 JetRanger X sit in the light single‑engine category. The H125 typically offers the longest practical range of the two and can carry more people, commonly around five to six passengers plus a pilot depending on configuration. The Bell 505 is generally shorter‑range and lower‑capacity, most often suited to about four passengers plus a pilot, emphasizing simplicity and cost efficiency. The Airbus H145 is a light twin‑engine helicopter, a step up in category for redundancy and utility. It usually delivers a moderate range and a noticeably larger cabin than the H125/505, commonly accommodating about seven to eight passengers in typical layouts. The Sikorsky S‑76D and Leonardo AW139 are medium twin‑engine helicopters aimed at corporate and offshore/utility missions. Both provide longer ranges than the lighter aircraft and higher passenger capacity. The S‑76D is often configured around eight passengers (with options higher), while the AW139 is generally the larger-capacity and often longer‑range platform, frequently arranged for about 10 to 12 passengers, with higher-density layouts possible.
