Airbus Helicopters H155 vs Leonardo Aw109 Trekker

Both the Airbus Helicopters H155 and the Leonardo AW109 Trekker are twin‑engine civil helicopters, but they sit in different size and mission categories. The H155 is a medium twin designed for higher payload and cabin volume, commonly positioned for offshore transport, corporate/VIP missions, and EMS where a larger cabin and smoother ride are priorities. The AW109 Trekker is a lighter twin in the AW109 family, aimed at versatile utility and corporate missions with strong speed and operating flexibility, including operations from more constrained sites. In range, the H155 typically offers longer endurance and greater mission radius in practical passenger configurations, benefiting from higher fuel capacity and efficiency in the medium class. The AW109 Trekker delivers competitive range for a light twin, but is generally used on shorter sectors than the H155 when carrying comparable loads. Passenger capacity also reflects the class difference. The H155 is usually configured to carry more passengers, often around 12 to 13 seats depending on layout. The AW109 Trekker commonly seats fewer, typically around 6 to 8 passengers, again depending on interior and mission equipment.
