Bell 525 Relentless vs Enstrom 480b vs Piaggio Avanti Evo vs Pilatus Pc 24
The Bell 525 Relentless and Enstrom 480B are helicopters, while the Piaggio Avanti EVO and Pilatus PC-24 are fixed‑wing turboprops/jet. The Bell 525 is a large, long‑range twin‑engine helicopter aimed at offshore, corporate, and SAR missions, typically carrying around 12–16 passengers in an executive layout and offering roughly 500–600 nautical miles of range depending on configuration. The Enstrom 480B is a smaller single‑engine helicopter best suited to utility, training, and light corporate use, generally carrying up to 4–5 people with a much shorter practical range, roughly 200–300 nautical miles. Among the fixed‑wing options, the Piaggio Avanti EVO is a high‑speed twin‑turboprop business aircraft, commonly configured for about 6–9 passengers and capable of about 1,500–1,800 nautical miles. The Pilatus PC‑24 is a light twin‑jet designed for versatile operations including short/rough runway access; it typically seats about 6–10 passengers (with higher‑density layouts possible) and offers roughly 1,800–2,000 nautical miles. Overall, the PC‑24 and Avanti dominate speed and range, the Bell 525 leads helicopter capacity and mission flexibility, and the 480B serves the light, lower‑cost end.
