Cessna 208b Grand Caravan Ex vs Piaggio Avanti Evo vs Piper M600 Sls vs Robinson R66

The Cessna 208B Grand Caravan EX is a single‑engine turboprop utility aircraft optimized for short, rough-field operations. It typically offers the longest real-world flexibility for hauling people or cargo, carrying about 9–14 occupants depending on configuration, with range roughly in the 900–1,100 nautical mile class. The Piaggio Avanti EVO is a twin‑engine turboprop in a faster, more business-oriented category, usually seating about 7–9 passengers. It generally delivers the longest range of this group, commonly around 1,400–1,800 nautical miles, and is geared toward high-speed point-to-point travel. The Piper M600 SLS is a single‑engine pressurized turboprop personal/business aircraft, typically seating about 4–6 passengers (up to 6). Its range is usually in the 1,200–1,500 nautical mile range, balancing speed, altitude, and operating simplicity. The Robinson R66 is a single‑engine turbine helicopter, typically carrying 4–5 occupants including the pilot. Its range is much shorter than the fixed‑wing turboprops, commonly about 300–400 nautical miles, but it offers vertical access where runways aren’t available.
