Airbus Helicopters H175 vs Airbus Helicopters H225 vs Bell 525 Relentless vs Leonardo Aw609 Tiltrotor vs Sikorsky S 76d vs Sikorsky S 92

The Airbus Helicopters H175 and H225, Bell 525 Relentless, Leonardo AW609 tiltrotor, and Sikorsky S-76D and S-92 span two main categories: medium and heavy conventional helicopters, plus one tiltrotor. The H175, Bell 525, and S-76D sit in the medium twin-engine class, typically used for offshore transport and corporate/VIP missions. Their ranges are broadly similar in the mid-hundreds of nautical miles, with the H175 and 525 generally positioned for longer legs than the S-76D depending on configuration. Passenger capacity in this group is usually around 12–16, with the S-76D commonly configured closer to the lower end and the 525 and H175 often higher. The H225 and S-92 are heavy twin helicopters aimed at higher-payload offshore and SAR roles. They tend to offer longer practical range and higher capacity, commonly around 16–19 passengers in offshore seating. The AW609 is a civilian tiltrotor rather than a helicopter; it trades rotorcraft hover capability for higher cruise speed and airplane-like range, typically carrying about 6–9 passengers while reaching significantly farther than most conventional helicopters.
