Bell 525 Relentless vs Daher Tbm 960 vs Piaggio Avanti Evo vs Piper M600 Sls

The Bell 525 Relentless is a twin‑engine helicopter, so it best fits missions needing vertical access—offshore, EMS, and point‑to‑point travel without runways. Its practical range is roughly in the 500–600 nautical mile class (mission dependent), and it typically carries about 16 passengers (plus crew) in an airliner‑style cabin. The Daher TBM 960 and Piper M600 SLS are single‑engine turboprop airplanes aimed at fast owner‑operator travel from runways. The TBM 960 is generally the longer‑legged of the two, commonly around 1,400+ nautical miles with reserves under typical cruise profiles, while the M600 SLS is usually closer to about 1,000–1,200 nautical miles. Both are normally configured for around 4–6 passengers plus pilot, with the TBM often flown with 4–5 in comfort. The Piaggio Avanti EVO is a twin‑turboprop airplane positioned between them and light jets, offering a larger, quieter cabin and higher typical passenger loads. Its range is commonly around 1,200–1,500 nautical miles, and it generally seats about 6–8 passengers.
