Airbus Helicopters H225 vs Beechcraft King Air 360 Er vs Bell 525 Relentless vs Piaggio Avanti Evo

The Airbus H225 and Bell 525 Relentless are large, long-range helicopters optimized for vertical lift missions (offshore energy, SAR, executive shuttle) where landing infrastructure is limited. Both typically carry around 12–16 passengers in high-density layouts (often fewer in VIP), with practical ranges roughly in the 400–600+ nautical mile class depending on payload and reserves; the H225 is a proven heavy twin, while the 525 is a newer fly-by-wire super-medium with competitive range and cabin flexibility. The Beechcraft King Air 360ER is a twin‑turboprop fixed‑wing aircraft aimed at efficient regional transport from short runways. It generally seats about 8–11 passengers (more in commuter configurations) and offers significantly longer range than the helicopters, roughly around 1,500–1,800+ nautical miles depending on configuration. The Piaggio Avanti EVO is a high-speed twin‑turboprop fixed‑wing aircraft positioned closer to light-jet trip profiles, typically seating about 6–9 passengers, with range commonly around 1,000–1,400 nautical miles and higher cruise speed than the King Air, trading some runway versatility for performance.
