Bell 525 Relentless vs Daher Tbm 960 vs Leonardo Aw189 vs Sikorsky S 92

The Bell 525 Relentless is a super‑medium twin helicopter aimed at offshore, corporate, and utility missions; it typically carries around 16 passengers in a transport layout and offers a range on the order of roughly 500–600 nautical miles depending on configuration. The Leonardo AW189 is also a super‑medium twin, commonly used for offshore and SAR; it generally seats about 16–19 passengers and has a similar medium‑range profile, often around the mid‑500‑nautical‑mile class with reserves varying by mission kit. The Sikorsky S‑92 is a larger heavy/large twin helicopter optimized for offshore transport; it usually carries about 19 passengers and tends to offer comparable or slightly higher practical range than the super‑mediums, often around 500+ nautical miles depending on payload and reserves. The Daher TBM 960, by contrast, is a high‑performance single‑engine turboprop airplane, not a helicopter; it is a fast owner‑pilot/business aircraft typically seating 4–6 passengers and has the longest range of this group at roughly 1,400–1,700 nautical miles, trading vertical‑lift flexibility for speed and efficiency.
