Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Daher Tbm 960 vs Piaggio Avanti Evo

The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter aimed at offshore, corporate, and high‑utilization missions. Compared with the fixed‑wing aircraft here, its strength is point‑to‑point access rather than pure range; it typically offers roughly 500–600 nm of range and commonly seats about 12–16 passengers depending on layout. The Cessna 208B Grand Caravan EX is a single‑engine utility turboprop built for rugged short fields and cargo/passenger flexibility. It generally carries about 9–14 passengers (often 9 in commuter service) and offers around 900–1,000 nm range depending on payload and reserves. The Daher TBM 960 is a high‑performance single‑engine turboprop in the personal/corporate category. It prioritizes speed and efficiency, typically seating 4–6 passengers with ranges commonly around 1,400–1,700 nm. The Piaggio Avanti EVO is a twin‑turboprop business aircraft with a cabin sized like a light jet and strong cruise speed. It usually seats about 7–9 passengers and offers roughly 1,400–1,800 nm range, varying with payload and mission profile.
