Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Enstrom 480b vs Md Helicopters (mcdonnell Douglas) 902 Explorer

The Bell 525 Relentless is a large, twin‑engine helicopter in the super‑medium class, aimed at offshore and corporate missions. It typically offers the highest passenger capacity of these four (often around 16–19 seats in typical layouts) with long helicopter range on the order of roughly 500–600 nautical miles, depending on configuration and reserves. The Cessna 208B Grand Caravan EX is a single‑engine turboprop fixed‑wing utility aircraft, not a helicopter, and it generally trades vertical‑lift capability for efficiency. It commonly carries about 9–14 passengers and usually has the longest range of this group, often around 900–1,000+ nautical miles depending on payload and tanks. The Enstrom 480B is a light, single‑engine piston helicopter, suited to training, patrol, and utility work. It has the smallest capacity, typically about 4–5 occupants total, and the shortest range, roughly a couple hundred nautical miles. The MD 902 Explorer is a light twin‑engine helicopter (NOTAR anti‑torque system) used for EMS and law enforcement. It typically seats about 7–10 and offers mid‑range helicopter legs, commonly around 300–400 nautical miles.
