The Bell 525 Relentless is a twin‑engine helicopter aimed at offshore, corporate shuttle, and parapublic missions, trading speed and altitude for vertical takeoff flexibility. Its range is roughly in the 500–600 nautical mile class, and typical passenger capacity is about 16–19 depending on cabin configuration. The Bombardier Global 7500 is an ultra‑long‑range business jet designed for intercontinental city pairs. It offers about 7,700 nautical miles of range and typically carries 14–19 passengers in executive layouts (with higher maximums possible depending on certification and seating). The Piaggio Avanti EVO is a twin‑turboprop business aircraft positioned between light jets and larger turboprops for speed and efficiency. Its range is roughly 1,700–1,900 nautical miles, and it generally seats about 6–9 passengers. The Piper M600 SLS is a single‑engine turboprop optimized for owner‑operators and shorter business trips. Its range is about 1,400–1,500 nautical miles with reserves, and it typically carries 1–5 passengers plus the pilot (up to six seats total).
