Airbus Helicopters H155 vs Airbus Helicopters H225 vs Beechcraft King Air 360er vs Bell 525 Relentless vs Cessna Grand Caravan Ex vs Pilatus Pc 12 Ngx
By category, the Airbus Helicopters H155 and Bell 525 Relentless are medium twin-engine helicopters aimed at fast executive/VIP and offshore-style missions, while the Airbus Helicopters H225 is a larger heavy twin-engine helicopter optimized for high payload offshore transport and SAR. The Beechcraft King Air 360ER and Pilatus PC‑12 NGX are pressurized turboprop business/utility airplanes, with the King Air emphasizing twin-engine redundancy and the PC‑12 emphasizing single-engine efficiency and rugged-field versatility. The Cessna Grand Caravan EX is a high-utility unpressurized single turboprop designed for simple, high-cycle regional, cargo, and remote operations. On range, the H155 and Bell 525 typically sit in the mid-range helicopter class (roughly a few hundred nautical miles), the H225 generally offers longer helicopter range and endurance than the medium twins, and the fixed-wing turboprops (King Air 360ER and PC‑12 NGX) reach much farther, commonly around the 1,500–2,000+ nautical mile class depending on fit and reserves; the Caravan EX is usually shorter-range than the pressurized turboprops but can still exceed many helicopters. On passenger capacity, the H155 and Bell 525 commonly carry about 10–16, the H225 about 16–19, the King Air 360ER and PC‑12 NGX typically 6–10 in executive layouts (more in commuter), and the Caravan EX often 9 passengers (or substantial cargo).
