Airbus Helicopters H160 vs Bell 525 Relentless vs Dassault Falcon 2000s vs Embraer Legacy 500 vs Gulfstream G280 vs Leonardo Aw139 vs Sikorsky S 76d

The Airbus Helicopters H160, Leonardo AW139, Sikorsky S‑76D, and Bell 525 Relentless are medium twin helicopters, generally optimized for point-to-point access and short to medium missions. In typical configurations they seat about 8–15 passengers depending on layout, with practical ranges roughly in the 450–700 nautical mile class; the Bell 525 and AW139 tend to sit toward the higher end of capacity and/or range, while the S‑76D is often configured with fewer seats but strong speed and efficiency, and the H160 emphasizes modern aerodynamics and cabin comfort in a similar mission band. The Dassault Falcon 2000S, Embraer Legacy 500, and Gulfstream G280 are business jets intended for longer nonstop travel at higher speed and altitude. They typically carry about 8–12 passengers in executive seating. Range generally steps up from the Legacy 500 in the ~3,000+ nautical mile class to the Falcon 2000S around the mid‑3,000s, with the G280 typically reaching the high‑3,000 to ~4,000 nautical mile class, making it the longest-legged of the three.
