Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Dassault Falcon 8x vs Piper M600 Sls

The Bell 525 Relentless is a fly-by-wire, super‑medium helicopter aimed at offshore and corporate missions. It typically carries around 12–16 passengers (depending on layout) and offers roughly 500–600 nautical miles of range, trading speed and cabin comfort for vertical access and point‑to‑point flexibility. The Cessna 208B Grand Caravan EX is a single‑engine turboprop utility aircraft focused on rugged, short-field operations. It commonly seats 9–14 passengers and has an approximate range around 800–900 nautical miles, emphasizing payload flexibility over cruise speed and luxury. The Dassault Falcon 8X is a long‑range, large‑cabin tri‑jet business aircraft. It generally accommodates 12–16 passengers in executive configurations and is built for intercontinental flying, with about 6,400 nautical miles of range. The Piper M600 SLS is a pressurized, single‑engine turboprop positioned as a personal/corporate step‑up aircraft. It typically seats 5–6 passengers and offers roughly 1,400 nautical miles of range, balancing efficiency and avionics sophistication with smaller cabin capacity.
