Airbus Helicopters H125 vs Leonardo Aw109 Trekker vs Leonardo Aw119kx vs Leonardo Aw139

The Airbus Helicopters H125 is a light single‑engine utility helicopter, typically used for training, work, and high‑altitude operations; its practical range is generally in the roughly 300–350 nm class, and it usually carries about 5–6 passengers plus a pilot (depending on configuration and weights). The Leonardo AW109 Trekker is a light twin optimized for speed and corporate/EMS roles; it commonly offers a similar or slightly longer practical range than the H125 (often around the mid‑300 nm class) while carrying about 6–7 passengers with one or two pilots. The Leonardo AW119Kx is a light single emphasizing a larger cabin than many singles; it tends to have a practical range in the low‑to‑mid 300 nm class and typically seats about 6–7 passengers plus a pilot. The Leonardo AW139 is a medium twin designed for offshore, SAR, and high‑utilization transport; it generally delivers a longer practical range (often around 500 nm class, configuration‑dependent) and carries roughly 12–15 passengers with one or two pilots. Actual range and seating vary with fuel, reserves, payload, and mission kit.
