Beechcraft Kingair Denali vs Piaggio Avanti Evo vs Piper M350 vs Piper M500 vs Piper M600 Sls

The Beechcraft King Air Denali and Piaggio Avanti EVO are twin‑engine turboprops positioned for higher-speed, higher-utilization corporate and charter missions. The Denali is a modern, pressurized, single‑pilot-capable cabin turboprop with typical ranges in the roughly 1,500–1,700 nm class and usually seats about 6–9 passengers depending on layout. The Avanti EVO is also pressurized and twin‑turboprop, emphasizing jet-like cruise speed; its typical range is around 1,500–1,700 nm and it commonly carries about 6–7 passengers in an executive interior. The Piper M350 is a pressurized single‑engine piston aircraft aimed at owner‑pilots, with shorter typical range (about 1,000–1,300 nm) and usually 5–6 seats. The Piper M500 and M600 SLS are pressurized single‑engine turboprops, stepping up in speed and capability over the M350. The M500 typically offers around 1,000–1,400 nm of range and about 5–6 seats, while the M600 SLS generally stretches to roughly 1,300–1,600 nm and also seats about 5–6, focusing on higher payload and advanced avionics.
