Airbus Helicopters H175 vs Airbus Helicopters H215 vs Airbus Helicopters H225 vs Bell 525 Relentless vs Leonardo Aw609 Tiltrotor vs Sikorsky S 76d vs Sikorsky S 92

The Airbus H175, H215, H225, Bell 525 Relentless, Leonardo AW609, Sikorsky S-76D, and Sikorsky S-92 span medium to heavy vertical-lift and one tiltrotor category. The H175 and Bell 525 are modern “super-medium” helicopters typically used for offshore and VIP; both generally seat about 16 passengers in high-density layouts and offer medium-long ranges roughly in the 500–700 km class depending on fit and reserves. The Sikorsky S-76D is a lighter medium twin aimed at corporate and EMS; it commonly carries about 8–12 passengers with shorter-to-medium range, often around 600 km or less by mission. The H215 is a medium-lift workhorse (often utility/offshore) with capacity commonly around 19 passengers and moderate range. The H225 and Sikorsky S-92 sit in the heavy offshore/transport class, typically configured around 19 passengers (sometimes more in utility layouts) with longer legs often around 700–1,000 km class. The Leonardo AW609 is a tiltrotor, bridging helicopter and airplane performance; it carries about 6–9 passengers and trades rotorcraft hover capability for notably higher cruise speed and generally longer range, often around 1,000 km class.
