Leonardo Aw189 vs Piaggio Avanti Evo vs Piper M600 Sls vs Robinson R66

The Agusta/Leonardo AW189 and Robinson R66 are helicopters, while the Piaggio Avanti EVO and Piper M600 SLS are fixed‑wing turboprops; this drives big differences in range and cabin use. The AW189 is a medium twin‑engine helicopter typically used for offshore, SAR, and utility missions, offering the largest passenger capacity of the group at roughly 16–19 seats and a moderate range around 450–500 nautical miles depending on fit and reserves. The Robinson R66 is a light single‑engine helicopter aimed at private and light commercial roles, usually carrying 4 passengers plus a pilot (about 5 total) with a typical range around 300 nautical miles. The Piaggio Avanti EVO is a high‑speed twin‑turboprop business aircraft, generally seating about 6–7 passengers, with longer legs around 1,400–1,700 nautical miles and higher cruise speed than the helicopters. The Piper M600 SLS is a single‑engine pressurized turboprop in the personal/business category, typically carrying about 5–6 passengers with a range around 1,000–1,200 nautical miles.
