Airbus Helicopters H155 vs Airbus Helicopters H160 vs Bell 525 Relentless vs Leonardo Aw109 Grand New vs Leonardo Aw139 vs Leonardo Aw609 Tiltrotor vs Sikorsky S 76d

The Airbus H155 and Sikorsky S-76D sit in the midsize twin category, typically carrying about 8–12 passengers with practical ranges around roughly 450–500 nautical miles, making them common for offshore, corporate, and EMS roles. The Airbus H160 is a newer-generation medium twin, generally configured for about 8–12 passengers as well, with a similar ballpark range (often around 450–500 nautical miles) but with a design emphasis on efficiency, cabin comfort, and reduced noise. The Bell 525 Relentless and Leonardo AW139 are larger “super-medium” twins, usually arranged for roughly 12–16 passengers and aimed at longer offshore legs; real-world ranges commonly land in the neighborhood of about 500–600+ nautical miles depending on fit and reserves. The Leonardo AW109 Grand New is a light twin, typically around 6–7 passengers, optimized more for speed and short-to-medium missions, with ranges often around 400–500 nautical miles. The Leonardo AW609 tiltrotor is a different category: a civil tiltrotor rather than a helicopter, typically around 6–9 passengers, offering airplane-like cruise and longer point-to-point reach (often cited around 700+ nautical miles).
