Bell 525 Relentless vs Cessna Grand Caravan Ex vs Cessna Skycourier vs Daher Kodiak 100 Series Iii vs Pilatus Pc 12 Ngx
The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter, so it sits in a different category than the others: it trades fixed‑wing cruise efficiency for vertical lift, point‑to‑point access, and hover capability. Its typical mission range is roughly in the 500–600 nautical mile class, and it generally carries around 12–16 passengers depending on interior. The Cessna Grand Caravan EX, Daher Kodiak 100 Series III, and Cessna SkyCourier are single‑engine (Caravan, Kodiak) and twin‑engine (SkyCourier) turboprop utility aircraft optimized for short/rough-field work. The Caravan EX and Kodiak commonly carry about 9–10 passengers, with ranges generally around the 600–1,000 nautical mile band depending on payload and reserves. The SkyCourier is larger and aimed at higher-volume commuter/cargo roles; it typically seats about 19 passengers and offers similar regional range, often roughly 900–1,200 nautical miles with typical loads. The Pilatus PC‑12 NGX is a pressurized, higher-performance single‑engine turboprop in the “executive utility” class. It usually seats about 6–9 in executive layouts (more in commuter), and it tends to lead this group in practical cruise range, commonly around 1,500+ nautical miles depending on configuration.
