Beechcraft King Air 360 Er vs Bell 525 Relentless vs Enstrom 480b vs Gulfstream G700

The Beechcraft King Air 360ER is a twin‑engine turboprop business/utility aircraft suited to short and unimproved runways, typically carrying about 6–9 passengers with an extended range around 1,500–1,800 nautical miles depending on configuration and reserves. The Bell 525 Relentless is a fly‑by‑wire super‑medium helicopter aimed at offshore and corporate missions, generally seating roughly 12–16 passengers with a range on the order of 500–600 nautical miles. The Enstrom 480B is a light turbine helicopter primarily used for training, patrol, and utility work, usually carrying 4–5 people with a typical range around 300–400 nautical miles. The Gulfstream G700 is an ultra‑long‑range business jet optimized for high-speed intercontinental travel, commonly configured for about 13–19 passengers (and certified for more), with a range roughly 7,000–7,750 nautical miles. Overall, the G700 dominates range and cabin volume, the King Air 360ER balances efficiency and access to smaller airports, while the Bell 525 and Enstrom 480B trade range for vertical-lift flexibility and point-to-point access.
