Airbus Helicopters H125 vs Airbus Helicopters H135 vs Leonardo Aw109 Trekker vs Leonardo Sh09

Airbus Helicopters’ H125 is a light single‑engine utility helicopter, typically used for work missions and flexible short‑ to mid‑range transport; it generally carries about five to six passengers (plus pilot) and offers roughly a 330–360 nm class range depending on fit and reserves. The H135 is a light twin‑engine helicopter optimized for passenger transport, EMS, and corporate use; it usually seats about five to seven passengers and has a similar mid‑range profile, commonly around the mid‑300 nm class, with twin‑engine redundancy and a quieter cabin-focused design. Leonardo’s AW109 Trekker sits in the light twin category but is positioned toward faster, longer‑leg passenger and mixed utility missions; typical seating is about six to seven passengers, and range is often in the high‑300 nm class, with options that can extend it further depending on tanks and payload. The Leonardo SH09 is a light single‑engine design aimed at straightforward utility and passenger roles; expected capacity is around four to five passengers, with a range generally comparable to other light singles, but final figures depend on certification configuration and published performance data.
