Airbus Helicopters H155 vs Airbus Helicopters H175 vs Leonardo Aw169 vs Leonardo Aw189

All four are twin‑engine civil helicopters but sit in different size classes. The Airbus H155 and Leonardo AW169 are in the light‑intermediate category: they typically carry about 8–10 passengers in an executive or offshore layout, with practical ranges generally in the mid‑400 to roughly 500+ nautical mile class depending on tanks, payload, and reserves. Moving up, the Airbus H175 is a super‑medium, most often configured around 12–16 passengers for offshore transport, with range commonly around the mid‑500 nautical miles, again varying by mission kit and fuel options. The Leonardo AW189 is also a super‑medium and is broadly comparable in role to the H175, usually seating about 16–19 passengers and offering a similar long‑range offshore profile, often around the mid‑500 nautical mile class. In short, H155/AW169 prioritize smaller cabin missions and flexibility, while H175/AW189 prioritize higher passenger counts and longer offshore legs.
