Airbus Helicopters H225 vs Bell 525 Relentless vs Cessna Citation Xls vs Piaggio Avanti Evo

The Airbus H225 and Bell 525 Relentless are large, long-range helicopters suited to offshore, utility, and VIP missions. The H225 is a heavy twin with typical ranges around 450–500 nm and generally carries about 16–19 passengers in high-density seating (fewer in VIP). The Bell 525 is a modern super-medium twin, typically offering roughly 500–560 nm range and commonly seats around 16 passengers (often fewer in executive layouts). The Cessna Citation XLS+ is a midsize business jet optimized for speed and point-to-point travel; it typically flies about 1,800–2,100 nm and usually seats 7–9 passengers in standard executive configuration. The Piaggio Avanti EVO is a high-performance twin turboprop with jet-like cruise efficiency; it commonly ranges around 1,300–1,700 nm and typically seats 6–7 passengers (up to about 9 in some layouts). Overall, the helicopters prioritize vertical access with shorter ranges, while the XLS+ and Avanti EVO prioritize longer range and faster cruise, with the jet generally offering the greatest range and speed.
