Bell 525 Relentless vs Cessna Citation Xls vs Enstrom 480b vs Piper M600 Sls
The Bell 525 Relentless and Enstrom 480B are helicopters, while the Cessna Citation XLS+ and Piper M600 SLS are fixed‑wing airplanes; the Citation is a light business jet, and the M600 is a single‑engine turboprop. In range, the Citation XLS+ generally leads this group, designed for longer business trips and typically capable of roughly 2,000+ nautical miles depending on payload and conditions. The Piper M600 SLS is next, commonly around the 1,000–1,500 nautical mile class. The Bell 525 targets medium twin helicopter missions and typically sits in the mid‑hundreds of nautical miles range, while the Enstrom 480B is a lighter piston helicopter and is usually shorter‑range than the 525, also in the few‑hundred‑mile category. For passenger capacity, the Citation XLS+ is typically arranged for about 7–9 passengers plus crew. The Bell 525 cabin is sized for roughly 10–16 occupants depending on configuration. The Piper M600 SLS generally carries up to 5 passengers plus a pilot. The Enstrom 480B is typically a 4–5 seat helicopter including the pilot.
