Piper M350 vs Piper M600 Sls vs Piper Seminole

The Piper M350 and M600 SLS are pressurized, single‑engine turboprop family aircraft aimed at higher‑end personal and business travel, while the Piper Arrow is an unpressurized, piston‑engine retractable‑gear aircraft commonly used for training, time‑building, and shorter personal trips. In category, the M350 is a pressurized piston single, the M600 SLS is a pressurized turboprop single with higher cruise speeds and more power, and the Arrow is a complex piston single without cabin pressurization. For range, the M600 SLS is generally the longest‑leg option, typically around 1,000–1,500 nautical miles depending on configuration and reserves, with the M350 usually somewhat shorter (often roughly 1,000–1,300 nautical miles). The Arrow’s practical range is markedly less, commonly in the several‑hundred‑nautical‑mile class depending on tank size and power settings. Passenger capacity is similar on paper for the M350 and M600 SLS, typically seating about six, whereas the Arrow is usually a four‑seat aircraft.
