Airbus Helicopters H135 vs Airbus Helicopters H145 vs Leonardo Aw139 vs Sikorsky S 92

The Airbus Helicopters H135 is a light twin, typically used for EMS, training, and short-hop utility missions. Its practical range is generally in the roughly 300–350 nautical mile class (about 550–650 km, mission fit dependent), and it commonly carries around 5–6 passengers in a standard cabin layout (more in high-density seating). The Airbus H145 sits in the light-to-medium twin category with a larger cabin and higher useful load. Range is often around 330–360 nautical miles (about 600–670 km), and typical passenger capacity is about 7–8, with higher-density configurations possible. The Leonardo AW139 is a medium twin optimized for offshore, corporate, SAR, and utility work. It usually offers around 550–600 nautical miles of range (about 1,020–1,110 km, depending on tanks and reserves) and commonly seats about 12–15 passengers. The Sikorsky S-92 is a heavy twin designed for demanding offshore and SAR roles. It generally provides roughly 500–550 nautical miles of range (about 930–1,020 km) and typically carries about 18–19 passengers in offshore-style seating.
