Airbus Helicopters H135 vs Airbus Helicopters H155 vs Leonardo Aw169 vs Leonardo Aw189

The Airbus H135 is a light twin in the short-range category, typically used for EMS, training, and utility missions. It generally offers the shortest range of the four and usually seats about 5–7 passengers in a standard passenger layout (configuration dependent). The Leonardo AW169 and Airbus H155 sit in the intermediate/midsize twin category, stepping up in range and cabin volume; both commonly carry around 8–10 passengers, with the AW169 often positioned as a modern, flexible 4–5 ton-class helicopter and the H155 as a larger-cabin midsize option aimed at corporate, SAR, and offshore support. The Leonardo AW189 is the clear heavy/large-cabin twin in this group, optimized for offshore and SAR, with the greatest range and payload flexibility; it commonly carries roughly 16–19 passengers in typical offshore seating. Overall, range and passenger capacity scale upward from H135 to AW169/H155, and peak with the AW189, while all vary notably with fuel reserves, mission equipment, and cabin fit.
