Airbus Helicopters H160 vs Airbus Helicopters H175 vs Bell 525 Relentless vs Leonardo Aw139

The Airbus Helicopters H160 is typically positioned as a modern medium twin for corporate and offshore missions, offering a moderate range (roughly in the 450–550 nm class depending on fit and reserves) and a usual passenger load around 8–12, with maximum seating in the low teens in high-density layouts. The Airbus Helicopters H175 sits a class above as a super-medium, aimed strongly at offshore transport; it generally provides longer range (commonly about 550–650 nm) and more seats, typically about 12–16 passengers in offshore or airline-style configurations. Bell’s 525 Relentless is also a super-medium competing closely with the H175, targeting similar offshore and VIP roles with comparable range (about 550–650 nm) and cabin capacity commonly in the 12–16 passenger band, depending on interior and regulatory limits. The Leonardo AW139 is a widely used intermediate/medium twin that can be configured flexibly; its range is often somewhat lower than the super-medium pair (frequently around 450–600 nm depending on tanks and payload), and passenger capacity is commonly about 10–15, with layouts varying significantly by mission.
