The Bell 525 Relentless and Robinson R66 are helicopters, while the Cessna 208B Grand Caravan EX is a single‑engine turboprop airplane and the Gulfstream G700 is an ultra‑long‑range business jet. The Gulfstream G700 sits at the top end by range, typically capable of roughly 7,000+ nautical miles, and it carries the most people in comfort, often configured for about 10–19 passengers depending on layout. The Cessna 208B Grand Caravan EX is a utility turboprop optimized for short to medium regional legs, generally around 900–1,200 nautical miles, and commonly carries up to about 9–14 passengers depending on seating and regulations. The Bell 525 is a large civil helicopter designed for offshore and executive transport; it offers midrange helicopter performance, roughly around 500–600 nautical miles, with seating that typically lands in the mid‑teens in high‑density configurations but varies by cabin fit. The Robinson R66 is a light helicopter with the shortest range of this group, around 300–350 nautical miles, and the smallest capacity at about 4–5 seats including the pilot.
