Airbus Helicopters H225 vs Bell 525 Relentless vs Bombardier Global 7500 vs Robinson R66

The Airbus H225 and Bell 525 Relentless are large, long-range helicopters aimed at offshore, SAR, and VIP transport. The H225 is a heavy twin with very high useful load and typically seats around 19 passengers in an airline-style layout, with a practical range on the order of roughly 500–600 nautical miles depending on reserves and configuration. The Bell 525 is a super‑medium twin that generally carries fewer passengers (often mid‑teens, around 16–20 depending on layout) and offers comparable or slightly longer range in many mission profiles, commonly quoted around the mid‑500 nautical mile class. The Bombardier Global 7500 is a long‑range business jet in a different category entirely: it is designed for intercontinental missions with ranges around 7,700 nautical miles and typically carries about 8–19 passengers depending on cabin configuration, prioritizing speed and nonstop distance over vertical lift. The Robinson R66 is a light single‑engine helicopter suited to short-range utility and private travel, typically seating 4–5 passengers total (including the pilot) with range roughly in the 300 nautical mile class.
