Beechcraft King Air 360 Er vs Bell 525 Relentless vs Robinson R66 vs Sikorsky S 92
The Beechcraft King Air 360ER is a twin‑turboprop fixed‑wing airplane suited to longer point‑to‑point travel. It typically carries about 6–9 passengers (depending on configuration) and offers roughly 1,500–1,800 nautical miles of range, making it the best choice here for efficient regional to long‑regional trips between airports. The Bell 525 Relentless is a large, fly‑by‑wire twin‑engine helicopter aimed at offshore and corporate missions. It generally seats around 12–16 passengers and has an approximate range on the order of 500–700 nautical miles, trading speed and runway independence for shorter legs than the King Air. The Robinson R66 is a light single‑engine turbine helicopter for utility and short executive hops. It usually carries 4–5 occupants total and has a typical range around 300–350 nautical miles. The Sikorsky S‑92 is a heavy twin‑engine helicopter widely used offshore and for SAR/VIP transport. It commonly carries about 19 passengers (higher in some layouts) with a typical range around 500–600 nautical miles.
