Bell 525 Relentless vs Bombardier Global 7500 vs Leonardo Aw189 vs Piper M600 Sls

The Bell 525 Relentless and Leonardo AW189 are both twin‑engine, medium‑class helicopters aimed at offshore, corporate, and utility missions. The AW189 typically seats more passengers in a high‑density cabin (often up to around 16–19 depending on configuration), while the Bell 525 is commonly configured for fewer in executive layouts (often around 12–16). Their ranges are broadly comparable for the class, generally in the several‑hundred‑nautical‑mile bracket (roughly 400–500+ nm depending on fuel, reserves, and payload). The Bombardier Global 7500 is a long‑range, large‑cabin business jet in a different league for distance, designed for intercontinental missions with an advertised range around 7,700 nm, and typical seating for about 14–19 passengers depending on layout. The Piper M600 SLS is a single‑engine turboprop airplane for owner‑pilots and small teams. It carries up to 6 occupants and offers a medium range for its class (roughly 1,400–1,600 nm), far less than the Global 7500 but generally more than either helicopter.
