Airbus Helicopters H155 vs Airbus Helicopters H160 vs Airbus Helicopters H175 vs Bell 525 Relentless vs Leonardo Aw139 vs Leonardo Aw169 vs Sikorsky S 76d

The Airbus H155 and Sikorsky S‑76D sit in the light–medium twin category, typically optimized for corporate and offshore shuttle work, with roughly 1,000–500 nm class range depending on fit and reserves, and usual seating around 8–12 passengers. The Leonardo AW169 is also a light intermediate twin; it generally carries a similar passenger count (about 8–10 in typical layouts) with comparable or slightly shorter range depending on mission equipment. Moving up, the Airbus H160 targets the medium twin segment with modern efficiency; it commonly seats about 10–12 and offers solid mid-range capability, often around the 500 nm class in typical configurations. The Leonardo AW139 and Airbus H175 are firmly medium twins and among the most common offshore/EMS/SAR platforms; they usually accommodate around 12–16 passengers with ranges commonly in the 500–700 nm class depending on tanks and payload. The Bell 525 Relentless is a super‑medium, aimed at longer-range offshore missions, typically carrying around 12–16 passengers with range generally in the upper end of this group, often around 600–800 nm depending on configuration.
