Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Piaggio Avanti Evo

The Bell 525 Relentless and the MD Helicopters 902 Explorer are rotorcraft, optimized for point-to-point access, rooftop/remote landings, and vertical operations, while the Cessna 208B Grand Caravan EX and Piaggio Avanti EVO are fixed‑wing turboprops aimed at longer cruise legs between runways. In range, the Avanti EVO is generally the longest‑legged of the group (around 1,700+ nautical miles), followed by the Bell 525 (roughly around 1,000 nautical miles), with the Grand Caravan EX and MD 902 typically in the several‑hundred‑to‑~900 nautical mile class depending heavily on payload and reserves. For passenger capacity, the Grand Caravan EX usually carries the most in a commuter configuration (commonly up to about 9–14 seats depending on layout and regulations), the Bell 525 is typically configured around 12–16 seats in offshore/corporate layouts, the Avanti EVO is usually a 6–9 passenger executive aircraft, and the MD 902 is generally around 7–8 passengers including the pilot, making it the smallest-capacity option here.
