Beechcraft King Air 360 Er vs Bell 525 Relentless vs Boeing Bbj Max 9 vs Leonardo Aw189

The Beechcraft King Air 360ER is a twin‑turboprop airplane suited to short and medium hops, offering roughly 1,500–1,800 nm range depending on configuration and typically seating about 6–9 passengers in executive layouts. The Bell 525 Relentless is a long‑range twin‑engine helicopter aimed at offshore and VIP missions; its range is roughly 500–700 nm and it generally carries around 12–16 passengers, trading speed and range for vertical lift and point‑to‑point access. The Boeing BBJ MAX 9 is a large long‑range business jet based on the 737 MAX 9; it is in a different class, with approximately 3,200–3,500 nm range and a cabin that can be outfitted for about 25–50 passengers (or more in higher‑density arrangements). The Leonardo AW189 is a super‑medium twin helicopter focused on offshore transport and SAR/VIP roles, typically around 450–550 nm range and about 12–16 passengers, again prioritizing VTOL capability over airplane‑like range.
