Bell 525 Relentless vs Bombardier Global 7500 vs Cessna 208b Grand Caravan Ex vs Piaggio Avanti Evo

The Bell 525 Relentless is a fly-by-wire, super‑medium helicopter aimed at offshore, corporate, and public-service missions. It typically carries about 12–16 passengers depending on interior and mission equipment, and its range is roughly in the 500–600 nautical mile class. The Bombardier Global 7500 is an ultra‑long‑range business jet designed for intercontinental travel. It commonly seats 14–19 passengers in executive layouts (certified for more), and offers about 7,700 nautical miles of range, making it the clear leader for nonstop long-haul flights. The Cessna 208B Grand Caravan EX is a single‑engine turboprop utility aircraft optimized for rugged, short-field operations and regional connectivity. It generally carries up to 9 passengers (or cargo configurations) and has a typical range around 900–1,200 nautical miles depending on payload and reserves. The Piaggio Avanti EVO is a high-speed twin‑turboprop business aircraft bridging turboprop efficiency with near light‑jet cruise performance. It usually seats 6–9 passengers and has roughly 1,500–1,800 nautical miles of range, offering longer legs and higher speed than the Caravan but far less range than the Global 7500.
