Airbus Helicopters H160 vs Airbus Helicopters H175 vs Bell 525 Relentless vs Leonardo Aw609 Tiltrotor

The Airbus Helicopters H160 is a medium twin conventional helicopter aimed at corporate and offshore shuttle work. It typically carries about 12 passengers in a high-density layout (often fewer in VIP), and its practical mission range is roughly in the 450–550 nautical mile class depending on payload and reserves. The Airbus Helicopters H175 is a larger super‑medium twin conventional helicopter optimized for offshore transport and SAR. It generally accommodates about 16–18 passengers, and offers a longer effective range than the H160, commonly around the 550–650 nautical mile class, again mission‑dependent. The Bell 525 Relentless is a super‑medium twin conventional helicopter positioned for offshore and executive roles. Typical seating is around 16–20 passengers, with range broadly comparable to the H175, often cited in the 550–650 nautical mile class depending on configuration. The Leonardo AW609 is a civil tiltrotor rather than a helicopter: it trades hover capability for much higher cruise speed and airplane‑like enroute efficiency. It is typically configured for about 6–9 passengers, with a longer point‑to‑point range often around the 700–1,000 nautical mile class, depending on reserves and payload.
