Airbus Helicopters H225 vs Bell 525 Relentless vs Embraer Legacy 650 E vs Enstrom 480b

The Airbus H225 and Bell 525 Relentless are large, long-range helicopters aimed at offshore, SAR, and executive missions. The H225 is a heavy twin that typically carries around 16–19 passengers in transport layouts (more in high-density), with range roughly in the 450–600 nautical mile class depending on configuration. The Bell 525 is a modern super-medium twin, usually configured for about 12–16 passengers, with broadly similar medium-long helicopter range, commonly around the 500 nautical mile class. The Embraer Legacy 650E is a long-range business jet rather than a helicopter, optimized for fast point-to-point travel. It typically seats about 13 passengers in executive cabin layouts and offers far greater range than the rotorcraft, roughly around 3,900 nautical miles, enabling intercontinental missions. The Enstrom 480B is a light single-engine helicopter used for utility, patrol, and training roles. It carries a pilot plus up to four passengers (about five seats total) and has a much shorter range than the larger twins, generally on the order of a few hundred nautical miles, making it best suited to local and regional flying rather than offshore or long-haul missions.
