Bell 525 Relentless vs Bombardier Global 7500 vs Daher Tbm 960 vs Piaggio Avanti Evo
The Bell 525 Relentless is a super‑medium helicopter designed for vertical lift missions rather than point‑to‑point jet travel. Its typical range is roughly 550–600 nautical miles, and it generally carries about 12–16 people depending on layout and mission equipment. The Bombardier Global 7500 is an ultra‑long‑range business jet optimized for intercontinental nonstop flying, with a range around 7,700 nautical miles and typical seating for about 14–19 passengers (higher maximums possible with dense configurations). The Daher TBM 960 is a high‑performance single‑engine turboprop, best suited to fast regional trips, offering about 1,400–1,700 nautical miles of range and usually seating 4–6 passengers (up to about 6 plus pilot depending on configuration). The Piaggio Avanti EVO is a twin‑turboprop business aircraft emphasizing speed and efficiency, with roughly 1,500–1,800 nautical miles of range and typically seating 6–8 passengers (up to 9 in some layouts). Overall, the Global 7500 dominates range and cabin capacity, while the TBM 960 and Avanti EVO trade long‑range capability for lower operating cost, and the Bell 525 trades runway independence for shorter range.
