Airbus Helicopters H125 vs Airbus Helicopters H130 vs Airbus Helicopters H135 vs Airbus Helicopters H155 vs Bell 505 Jetranger X vs Leonardo Aw109 Grand New vs Leonardo Aw109 Trekker vs Leonardo Aw119kx vs Robinson Helicopters R66

By category, the Airbus H125, Bell 505, Leonardo AW119Kx, and Robinson R66 are light single‑engine helicopters; the Airbus H130 is also light single‑engine but optimized for quieter, higher‑comfort passenger work. The Airbus H135 and H155 are light/medium twin‑engine types, with the H155 sitting in the larger “medium” class and typically offering the most cabin volume and mission flexibility. The Leonardo AW109 Grand New and AW109 Trekker are light twin‑engine helicopters, generally positioned for fast executive transport and utility roles. For range, light singles (R66 and Bell 505) are typically shortest to mid‑range; the H125 and AW119Kx often provide stronger practical range/endurance among singles depending on tanks and mission. The H130 is similar class but often traded toward cabin comfort over maximum payload/range. Twin‑engine models (H135 and AW109 variants) commonly provide solid mid‑range capability, while the H155 is typically among the longest‑range options in this set. Passenger capacity generally runs 4–5 passengers in the light singles, about 6–7 in the H130/H135/AW109 class (configuration dependent), and up to around 8–12 on the H155 depending on layout.
