Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Pilatus Pc 24 vs Robinson R66

The Bell 525 Relentless and Robinson R66 are helicopters, while the Cessna 208B Grand Caravan EX and Pilatus PC-24 are fixed‑wing airplanes, so their range and capacity reflect different missions. The Bell 525 is a large, modern twin‑engine helicopter aimed at corporate/utility and offshore roles; it typically carries around a dozen-plus passengers in a high‑density layout and offers medium-to-long helicopter range (roughly in the 500–600 nautical mile class). The Robinson R66 is a light single‑engine turbine helicopter best for private, training, and light utility work; it usually seats 4–5 total including the pilot and has shorter range (roughly 300–350 nautical miles). The Cessna 208B Grand Caravan EX is a single‑engine turboprop utility aircraft optimized for rugged strips and cargo/passenger hauling; it commonly carries up to about 9 passengers and offers solid regional range (around 900–1,000 nautical miles depending on load). The Pilatus PC‑24 is a twin‑engine light jet for business travel; it typically seats 6–10 and provides the longest range here, roughly 1,900–2,000 nautical miles.
