Bell 525 Relentless vs Boeing Bbj Max 9 vs Piaggio Avanti Evo

The Bell 525 Relentless is a fly-by-wire super‑medium helicopter best suited to point-to-point access where runways aren’t available, such as offshore platforms or city-adjacent landing sites. Its range is roughly in the 500–600 nautical mile class (mission dependent), and it typically carries about 16 passengers in an executive or high-density layout, trading long-haul efficiency for vertical-lift flexibility. The Boeing BBJ MAX 9 is a large, long-range VIP airliner in the business jet category, designed for intercontinental travel between major airports. Depending on configuration and reserves, it offers roughly 3,200–3,600 nautical miles of range and can be outfitted for a small VIP group (often a few dozen) or a much higher-capacity seating plan, with maximum layouts approaching airline-style counts. The Piaggio Avanti EVO is a fast, efficient twin‑turboprop business aircraft optimized for regional missions from conventional runways, including many shorter fields. It typically offers about 1,400–1,800 nautical miles of range and usually seats 6–9 passengers in executive comfort.
