Bell 525 Relentless vs Daher Tbm 960 vs Embraer Legacy 650 E vs Piaggio Avanti Evo
The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter aimed at offshore and high‑end utility missions. It trades speed and range for vertical access, typically carrying about 16 passengers in an offshore-style layout, with practical range in the mid‑400‑nautical‑mile class depending on reserves and payload. The Daher TBM 960 is a single‑engine turboprop airplane optimized for owner‑pilots and fast regional trips; it seats up to about 6 passengers (plus pilot) and offers roughly 1,700–1,800 nautical miles of range, varying with speed and load. The Embraer Legacy 650E is a large‑cabin business jet designed for long nonstop missions and maximum comfort; it commonly carries 13 passengers (up to 19) and delivers about 3,900 nautical miles of range. The Piaggio Avanti EVO is a twin‑turboprop airplane with a quiet, stand‑up‑style cabin for its class; it typically seats 7–9 passengers and provides around 1,700–1,800 nautical miles of range. Overall, the Legacy 650E leads on range and cabin capacity, the TBM 960 and Avanti EVO serve efficient midrange travel, and the Bell 525 uniquely provides helicopter access.
