Airbus Helicopters H225 vs Bell 525 Relentless vs Boeing Bbj Max 9 vs Piaggio Avanti Evo
The Airbus H225 and Bell 525 Relentless are large, long‑range helicopters aimed at offshore, SAR, and VIP missions. The H225 typically offers longer endurance in many real‑world configurations and can carry more people in high‑density seating (roughly up to the mid‑teens to around 19), while the Bell 525 is a newer fly‑by‑wire design with a similar class mission radius and a practical passenger load generally in the low‑ to mid‑teens depending on layout. The Boeing BBJ MAX 9 is a large long‑range business jet based on an airliner, in a completely different category: it delivers intercontinental range (commonly cited around ~6,000+ nautical miles with auxiliary tanks and typical business payloads) and VIP cabins that usually seat a few dozen, but can be configured for far more. The Piaggio Avanti EVO is a twin‑turboprop business aircraft optimized for efficiency and speed; it has regional to transcontinental range (roughly ~1,500–1,800 nautical miles) and typically carries about 6–9 passengers in executive layouts.
