Beechcraft King Air 360 Er vs Bell 525 Relentless vs Dassault Falcon 8x vs Sikorsky S 92

The Beechcraft King Air 360ER is a twin‑turboprop fixed‑wing aircraft best suited to regional missions; it typically carries about 6–9 passengers and offers roughly 1,500–1,800 nautical miles of range depending on configuration and reserves. The Bell 525 Relentless is a super‑medium helicopter aimed at high-speed point‑to‑point access without runways; it generally seats around 12–16 passengers, with a typical range around 500–600 nautical miles. The Dassault Falcon 8X is an ultra‑long‑range business jet optimized for intercontinental travel; it commonly accommodates about 12–16 passengers (with higher-density layouts possible) and has a published range near 6,450 nautical miles. The Sikorsky S‑92 is a heavy helicopter widely used for offshore and utility transport; it typically carries about 19 passengers in a transport configuration and has an approximate range around 500–600 nautical miles. In short, the Falcon 8X dominates range, the King Air 360ER offers efficient regional flexibility, and the 525 and S‑92 trade range for vertical-lift access, with the S‑92 usually carrying the most people.
