Airbus Helicopters H155 vs Airbus Helicopters H160 vs Airbus Helicopters H215 vs Leonardo Aw109 Trekker vs Sikorsky S 76d

The Airbus H155 and Sikorsky S‑76D sit in the medium twin category, typically configured for about 8–12 passengers, and are often chosen for executive transport and offshore work; their practical range is broadly similar, commonly in the mid-hundreds of nautical miles depending on fit and reserves, with the S‑76D generally viewed as a fast, premium-cabin option. The Airbus H160 is a newer-generation medium twin, usually carrying roughly 8–12 passengers as well, but it is often marketed with more modern aerodynamics and avionics and tends to offer competitive or better mission range than legacy medium twins in comparable configurations. The Airbus H215 is a heavy twin (Super Puma class) focused on lifting and offshore/utility missions, carrying markedly more people—often around 16–24 passengers—and delivering longer mission endurance/range than the medium and light twins, again configuration-dependent. The Leonardo AW109 Trekker is a light twin, typically seating about 6–8 passengers, with shorter overall range than the medium and heavy types, optimized for lighter, faster point-to-point missions.
