Airbus Helicopters H225 vs Bell 525 Relentless vs Embraer Legacy 650 E vs Robinson R66

The Airbus H225 and Bell 525 Relentless are large, long-range twin‑engine helicopters aimed at offshore, SAR, and VIP transport. The H225 typically carries more people in high-density configurations (often around 19) and is optimized for heavy-lift and overwater missions, with range commonly in the ~450–550 nm class depending on fit. The Bell 525 is a newer super‑medium design generally configured around 16–20 passengers, with a broadly similar mission radius and range (roughly ~500 nm class), emphasizing modern avionics and high cruise efficiency. The Embraer Legacy 650E is a long‑range business jet in a different category altogether, offering much greater point‑to‑point range (about 3,900 nm) and a typical executive seating capacity around 13 passengers, trading vertical lift and rough‑field access for speed, altitude, and intercontinental reach. The Robinson R66 is a light single‑engine helicopter, best suited to short regional hops and utility/VIP use, typically seating 4 passengers plus pilot, with range commonly around ~300 nm, far below the heavy twins but at much lower operating complexity and cost.
