Airbus Helicopters H125 vs Airbus Helicopters H145 vs Airbus Helicopters H175 vs Leonardo Aw109 Grand New vs Leonardo Aw139

The Airbus H125 is a light single‑engine utility helicopter, best suited to short‑to‑medium missions, typically carrying a pilot plus about 5–6 passengers depending on fit and weight. The Leonardo AW109 Grand New is also a light helicopter but twin‑engine and generally positioned for faster corporate/EMS-style work, usually seating around 6–7 passengers with comparable short‑to‑medium range. Moving up, the Airbus H145 is a light twin optimized for EMS, law enforcement, and corporate shuttle, commonly configured for about 7–9 passengers and offering medium range with better payload and redundancy than the light singles. The Airbus H175 and Leonardo AW139 are medium twin‑engine helicopters aimed at offshore transport, SAR, and high‑capacity executive or utility roles; both deliver longer range and substantially higher cabin volume than the light class, typically accommodating roughly 12–16 passengers depending on layout and mission equipment. In general, capacity and range step up from H125/AW109 to H145, and then again to H175/AW139, with the AW139 and H175 competing most directly in the medium segment.
