Bell 525 Relentless vs Daher Tbm 960 vs Enstrom 480b vs Leonardo Aw189

The Bell 525 Relentless and Leonardo AW189 are both medium, twin‑engine helicopters aimed at offshore, corporate, and utility missions, but the AW189 is already widely fielded while the 525 is a newer, certification‑dependent entrant. In range, they are broadly comparable for the class, with typical mission ranges on the order of roughly 450–500 nautical miles depending on payload and reserves. Passenger capacity is similar as well, commonly configured around 12–16 seats in transport layouts, with higher-density options possible depending on interior and mission kit. The Enstrom 480B sits in a different helicopter category: a single‑engine light turbine helicopter focused on training, patrol, and personal/utility use. Its range is shorter, typically in the low‑to‑mid 300 nautical mile class, and passenger capacity is much smaller at up to five seats including the pilot. The Daher TBM 960 is not a helicopter but a high‑performance single‑engine turboprop airplane. It generally offers the longest range of the four, roughly 1,400+ nautical miles, with typical seating for about 4–6 passengers plus pilot depending on configuration.
