Bell 525 Relentless vs Daher Tbm 960 vs Piaggio Avanti Evo

The Bell 525 Relentless is a twin‑engine helicopter aimed at vertical-lift missions, trading runway independence for lower cruise efficiency than fixed‑wing aircraft. It typically carries up to about 16 passengers in high-density seating (fewer in executive layouts) and offers a practical mission range on the order of roughly 500–600 nautical miles, varying with payload and reserves. The Daher TBM 960 is a single‑engine turboprop airplane in the high‑performance personal/corporate category. It is optimized for speed and efficiency with runway access, usually seating 4–6 passengers (up to around 6–7 plus pilot depending on configuration). Its range is generally around 1,400–1,700 nautical miles, again depending on power settings, payload, and reserves. The Piaggio Avanti EVO is a twin‑engine turboprop airplane positioned as a fast, cabin-comfort business aircraft. It typically seats about 7–9 passengers and combines jet‑like cruise speeds with turboprop economics. Its range commonly falls around 1,400–1,700 nautical miles depending on configuration and mission profile.
