Airbus Helicopters H215 vs Bell 525 Relentless vs Leonardo Aw139

Airbus Helicopters’ H215 is a medium twin derived from the Super Puma family and is typically positioned as a rugged utility/transport helicopter. In common high-density layouts it can carry roughly 19 passengers, and it is generally optimized for short-to-medium range missions, with typical ranges on the order of about 300–450 nautical miles depending on configuration and reserves. Bell’s 525 Relentless is a “super-medium” twin aimed at longer-range, higher-speed offshore and executive transport. Typical seating is in the mid-to-high teens, and its advertised mission radius/range is generally greater than the other two, commonly cited around 500–600 nautical miles class depending on payload and fuel. Leonardo’s AW139 sits in the medium twin category and is widely used for EMS, SAR, offshore, and VIP roles. It typically seats around 12–15 passengers in standard transport layouts (higher in high-density), with a practical range commonly in the ~400–550 nautical mile band depending on variant, tanks, and mission equipment.
