Bell 525 Relentless vs Embraer Legacy 650 E vs Pilatus Pc 24 vs Piper M600 Sls
The Bell 525 Relentless is a fly-by-wire super‑medium helicopter, best suited to point-to-point missions without runways. It typically carries about 12–16 passengers in an offshore/VIP-style layout and offers roughly 500–600 nautical miles of range depending on configuration and reserves. The Embraer Legacy 650E is a large-cabin business jet focused on long, comfortable travel, commonly seating around 13 passengers (up to 14) and reaching about 3,900 nautical miles, making it the clear leader here for range and cabin volume. The Pilatus PC‑24 is a light jet optimized for versatility, including operation from shorter or semi-prepared runways; it generally seats 6–10 passengers and delivers about 2,000 nautical miles of range, balancing access and speed. The Piper M600 SLS is a single-engine turboprop aimed at owner-operators, typically carrying 5–6 passengers and offering roughly 1,200–1,400 nautical miles of range; it’s the smallest and simplest option, but economical and capable for regional trips.
