Airbus Helicopters H135 vs Airbus Helicopters H145 vs Leonardo Aw109 Trekker

The Airbus Helicopters H135 is typically positioned as a light twin for training, EMS, and short‑to‑medium utility work. It generally offers the shortest range of the three and the smallest cabin, most often carrying about six to seven passengers in a typical corporate/utility layout (or fewer when configured for EMS equipment), making it best suited to missions where compact size and lower operating footprint matter more than maximum cabin volume. The Airbus Helicopters H145 sits a step up in category as a larger light twin/midsize‑leaning utility helicopter with a notably roomier cabin and higher useful load. It commonly supports around eight to nine passengers in standard seating, and it usually provides the longest range among these three, aligning well with EMS, law enforcement, offshore support, and multi‑role utility missions that benefit from cabin space and endurance. The Leonardo AW109 Trekker is also a light twin, often oriented toward fast corporate transport and versatile utility roles. Passenger capacity is generally similar to the H135 at about six to seven passengers, while range typically falls between the H135 and H145, depending on configuration and fuel options.
