Beechcraft King Air 360 Er vs Bell 525 Relentless vs Boeing Bbj Max 9 vs Dassault Falcon 8x

The Beechcraft King Air 360ER is best viewed as a rugged, efficient twin‑turboprop for short to midrange missions and access to smaller airports; it typically carries about 6–9 passengers in executive layouts and offers roughly 1,800–2,000 nm range depending on payload and conditions. The Bell 525 Relentless is a long‑range, fly‑by‑wire helicopter aimed at offshore/VIP transport; it generally seats around 12–16 and has an advertised range on the order of about 500–600 nm, trading speed and altitude for vertical access. The Dassault Falcon 8X is an ultra‑long‑range business jet optimized for intercontinental point‑to‑point travel, commonly configured for about 12–16 passengers and capable of about 6,450 nm. The Boeing BBJ MAX 9 is a large‑cabin, airliner‑based VIP platform, suited to head‑of‑state or high‑capacity corporate missions; while it can be outfitted for dozens of passengers, it’s often configured around 25–50+ with very large living/meeting space, and its range is typically cited around 6,000–6,600 nm depending on configuration.
