Airbus Helicopters H160 vs Airbus Helicopters H175 vs Bell 525 Relentless vs Leonardo Aw139 vs Leonardo Aw169

All five are modern twin‑engine civil helicopters, but they span light‑intermediate to super‑medium categories. The Airbus H160 is typically positioned as a medium helicopter with a usually configured passenger load around 12 (layouts vary), and a range on the order of roughly 450–500 nautical miles depending on mission profile. The Airbus H175 sits in the super‑medium class, carrying about 16 passengers in common offshore layouts and offering a similar or slightly greater practical range, often cited around roughly 500–550 nautical miles with reserves depending on weights. Bell’s 525 Relentless is also a super‑medium, commonly marketed for 16–20 passengers, with a long-range capability broadly in the same bracket, around roughly 500–600 nautical miles depending on configuration. Leonardo’s AW139 is a medium helicopter, typically arranged for about 12–15 passengers, with range generally around roughly 500 nautical miles (variable with tanks, payload, and reserves). The Leonardo AW169 is lighter, in the light‑intermediate category, commonly configured around 8–10 passengers, with a shorter overall range typically around roughly 400–450 nautical miles, again strongly dependent on mission equipment and fuel/payload tradeoffs.
