Airbus Helicopters H155 vs Airbus Helicopters H160 vs Leonardo Aw139 vs Leonardo Aw189

The Airbus Helicopters H155 is a medium twin aimed at corporate and offshore shuttle work, with typical seating around 12 passengers (depending on layout) and a practical range commonly in the roughly 450–500+ nautical mile class, varying with reserves and cabin fit. The Airbus H160 is a newer-generation medium twin in a similar mission space, generally configured for about 12 passengers as well, and offers comparable or slightly better real-world range potential in many configurations, often cited around the 450–600 nautical mile bracket depending on payload and mission profile. The Leonardo AW139 is a widely used medium twin for offshore, EMS, and utility roles; it typically seats about 12–15 passengers and generally falls into a similar mid-range band, often around 500–600 nautical miles depending on tanks, payload, and reserves. The Leonardo AW189 steps up into the super-medium category, optimized for longer offshore legs, with typical passenger seating around 16–19 and correspondingly greater reach, often cited in the roughly 600–800 nautical mile class depending on configuration and operating assumptions.
