Airbus Helicopters H175 vs Bell 525 Relentless vs Leonardo Aw169 vs Leonardo Aw189 vs Sikorsky S 76d

Airbus Helicopters’ H175 and Leonardo’s AW189 sit in the super‑medium class, optimized for offshore and long overwater missions. They generally offer the longest practical range of this group (often around the 500–600+ nautical mile class, mission‑dependent) and the highest cabin capacity, typically configured for about 16–19 passengers in offshore layouts. Bell’s 525 Relentless is also a large, long‑range offshore‑oriented helicopter, broadly comparable in mission intent and usually in the same general range and seating bracket as the H175/AW189, depending on final configuration and reserves. Leonardo’s AW169 is a lighter intermediate helicopter aimed at EMS, corporate, and utility work. It typically carries fewer passengers, commonly around 8–10 in passenger transport, and has a shorter range than the super‑mediums (often roughly 400–500 nautical miles, mission‑dependent). Sikorsky’s S‑76D is a light‑intermediate twin frequently used for corporate and shorter offshore legs. Passenger capacity is typically around 8–12, with range commonly in the ~400–450 nautical mile class depending on payload and reserves.
