Airbus Helicopters H155 vs Airbus Helicopters H160 vs Airbus Helicopters H175 vs Bell 525 Relentless vs Leonardo Aw139 vs Leonardo Aw189

The Airbus H155 is a light–intermediate twin suited to shorter regional missions; typical range is roughly 450–500 nm, and it commonly seats about 8–12 passengers depending on layout. The Airbus H160 is a newer medium twin with similar passenger volumes (often 8–12) but generally more efficient mission capability; typical range is around 450–500+ nm. The Airbus H175 is a super-medium helicopter aimed at offshore and longer legs, with typical range around 500–550 nm and cabin configurations often around 12–16 passengers. Bell’s 525 Relentless sits in the super-medium class as well, targeting offshore/longer-range work; typical range is roughly 500–560 nm and typical passenger capacity is about 12–16. Leonardo’s AW139 is a medium twin widely used for EMS, SAR, and offshore; typical range is about 500–550 nm and it commonly carries around 10–15 passengers. The larger Leonardo AW189 is a super-medium optimized for offshore transport, with typical range around 500–550+ nm and typical seating around 16–19 passengers, generally offering the highest passenger capacity of this group.
