Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Pilatus Pc 24 vs Piper M600 Sls

The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter aimed at offshore and corporate missions. It typically carries around 16–20 passengers depending on configuration, with a practical range on the order of roughly 500–600 nautical miles, emphasizing vertical access over speed and runway needs. The Cessna 208B Grand Caravan EX is a single‑engine turboprop utility airplane focused on short-haul, rugged operations. It commonly seats 9 passengers (up to about 14 in high-density layouts) and offers a range generally in the 800–900 nautical mile class, trading speed for payload flexibility and short-field capability. The Pilatus PC‑24 is a light jet designed for fast business travel and “rough/short” runway access. Typical passenger capacity is about 6–10, and range is roughly 2,000 nautical miles, making it the longest‑leg option here. The Piper M600 SLS is a single‑engine pressurized turboprop positioned as a personal/business aircraft. It usually seats about 5–6 passengers with a range around 1,400 nautical miles, bridging utility turboprops and entry jets in speed and comfort.
