Beechcraft Baron G58 vs Beechcraft King Air 360 vs Beechcraft King Air 360er

The Beechcraft Baron G58 is a piston‑powered light twin typically used for personal and small business travel. It seats about five to six people and is best suited to regional trips, with a typical range on the order of roughly 1,000–1,500 nautical miles depending on payload, reserves, and operating conditions. The Beechcraft King Air 360 is a pressurized twin‑turboprop in the light business aircraft category. It generally carries about six to nine passengers in executive layouts and supports longer missions than the Baron, with typical range around roughly 1,500–1,800 nautical miles depending on configuration and conditions, plus higher cruise speeds and better high‑altitude capability. The Beechcraft King Air 360ER is a special‑mission, extended‑range variant of the 360. Passenger seating varies widely because it’s often configured for surveillance, ISR, medevac, or utility roles, but when arranged for passengers it is broadly similar in capacity to the 360. Its distinguishing feature is significantly greater endurance and range than the standard 360, commonly quoted around roughly 2,000+ nautical miles (mission dependent).
