Bell 525 Relentless vs Bombardier Global 7500 vs Piaggio Avanti Evo
The Bell 525 Relentless is a fly-by-wire super‑medium helicopter aimed at offshore, corporate, and utility missions where vertical access matters more than speed or intercity range. Its typical range is on the order of roughly 500–600 nautical miles (configuration dependent), and it generally carries about 12–16 passengers in a high-density cabin (often fewer in executive layouts). The Bombardier Global 7500 is an ultra‑long‑range business jet designed for nonstop intercontinental travel. It offers a published range around 7,700 nautical miles and typically seats about 14–19 passengers, depending on cabin configuration, with the most space, speed, and long-haul comfort of the three. The Piaggio Avanti EVO is a twin‑turboprop business aircraft optimized for efficient regional to mid-range trips, combining jet-like cruise speeds with lower operating costs. Its range is roughly 1,500–1,800 nautical miles, and it commonly carries about 7–9 passengers in executive seating.
