Airbus Helicopters H145 vs Airbus Helicopters H215 vs Airbus Helicopters H225 vs Leonardo Aw109 Trekker vs Leonardo Aw169 vs Leonardo Aw189 vs Sikorsky S 76d vs Sikorsky S 92"

In category terms, the Airbus H145 and Leonardo AW109 Trekker are light twins, typically used for short‑range corporate, EMS, and utility missions. Moving up, the Leonardo AW169 and Sikorsky S‑76D sit in the intermediate/light‑medium class, offering more cabin volume and payload for executive and offshore support. The Leonardo AW189 and Airbus H215 are medium twins, commonly configured for offshore transport and SAR with higher lift and longer legs than light types. At the top end, the Airbus H225 and Sikorsky S‑92 are heavy helicopters optimized for demanding offshore, SAR, and governmental roles, with the greatest payload and all‑weather capability. For range, light twins like H145 and AW109 generally cover the shortest sectors, intermediate types (AW169, S‑76D) extend practical legs, and medium/heavy aircraft (AW189, H215, H225, S‑92) typically deliver the longest offshore‑oriented ranges, depending on tanks and reserves. Passenger capacity follows the same progression: light twins commonly seat about 6–8 passengers, intermediate types often around 8–10, medium aircraft roughly 12–16, and heavy types generally around 16–19 (or more in high‑density layouts).
