Bell 525 Relentless vs Piaggio Avanti Evo vs Pilatus Pc 24 vs Piper M600 Sls
The Bell 525 Relentless is a twin‑engine helicopter best suited to vertical-lift missions and short-hop point-to-point travel where runway access is limited. It typically carries around 12–16 passengers in an executive configuration and offers roughly 500–600 nautical miles of range, varying with payload and reserves. The Piaggio Avanti EVO is a high-speed twin‑turboprop airplane optimized for efficient regional travel between airports. It commonly seats about 7–9 passengers and typically provides about 1,000–1,300 nautical miles of range depending on load and conditions. The Pilatus PC‑24 is a twin‑engine light jet designed for flexible operations, including many shorter or less-prepared runways than typical business jets. It generally carries about 6–10 passengers and offers roughly 1,900–2,000 nautical miles of range. The Piper M600 SLS is a single‑engine turboprop positioned as an owner-flown or small-cabin business aircraft. It seats up to 6 passengers and typically delivers around 1,400–1,600 nautical miles of range.
