Beechcraft King Air 360 Er vs Gulfstream G700 vs Piper M600 Sls vs Robinson R66

The Beechcraft King Air 360ER is a twin‑turboprop business aircraft suited to regional and remote-field operations, offering long endurance for its class (roughly 1,500–1,800 nm depending on load and reserves) and typically carrying about 6–9 passengers in an executive layout. The Gulfstream G700 is an ultra‑long‑range large‑cabin business jet designed for intercontinental travel, with a published range around 7,500 nm and typical seating in the teens (often 12–16, with higher-density options). The Piper M600 SLS is a single‑engine turboprop positioned as a personal/business aircraft, generally flying about 1,000–1,500 nm and seating up to 6, commonly 4–5 in comfort. The Robinson R66 is a light single‑engine helicopter for short‑range missions and flexible point‑to‑point access, with a range on the order of 300–350 nm and seating for up to 5 including the pilot (typically 4 passengers). Overall, the G700 leads in range and cabin capacity, the King Air balances versatility and efficiency, the M600 targets owner‑pilots, and the R66 prioritizes vertical access over distance.
