The Bell 525 Relentless and Robinson R66 are helicopters, while the Daher TBM 960 and Pilatus PC-24 are fixed‑wing turboprops/jet aircraft. The Bell 525 is a large, twin‑engine super‑medium helicopter aimed at offshore and corporate missions, typically carrying around 12–16 passengers with a range on the order of roughly 500–600 nautical miles depending on fit and reserves. The Robinson R66 is a light, single‑engine helicopter best suited to utility and short executive hops, usually carrying a pilot plus up to four passengers, with range roughly around 300 nautical miles. The TBM 960 is a high‑performance single‑engine turboprop airplane primarily for fast owner‑pilot or small corporate travel, typically seating 4–6 in comfort (up to about 6–7 including pilot) with range commonly around 1,500–1,700 nautical miles. The Pilatus PC‑24 is a light business jet with a larger cabin and more airline‑style flexibility, often configured for 6–10 passengers, with range roughly around 1,800–2,000 nautical miles, generally exceeding the TBM in cabin and payload while trading higher operating complexity and cost.
