Bell 525 Relentless vs Enstrom 480b vs Gulfstream G700 vs Leonardo Aw189

The Gulfstream G700 is a long-range, large-cabin business jet in a different class from the other three, offering intercontinental capability (about 7,500 nautical miles) and typically carrying around 12–19 passengers in executive layouts. The Bell 525 Relentless and Leonardo AW189 are both super-medium, twin‑engine helicopters aimed at offshore, corporate, and SAR/utility missions; they prioritize vertical access over cruise speed and runway independence. In general terms, the AW189 is configured for higher-density transport, commonly seating up to about 16–19 passengers depending on layout, with a typical range in the mid‑400‑nautical‑mile class (mission dependent). The Bell 525 is similar in role and size, usually accommodating roughly 16 passengers and offering broadly comparable mission ranges, often quoted around 500 nautical miles depending on reserves and payload. The Enstrom 480B is a much smaller single‑engine light helicopter primarily used for training, patrol, and utility work; it typically seats 5 (including the pilot) and has a much shorter range, roughly in the 200–300 nautical mile range.
