The Piaggio P-180 Avanti II was introduced in 2004 and, compared with earlier versions of this executive turboprop, the Avanti II has a Rockwell Collins ProLine 21 flight deck. The Avanti II can also have more powerful Pratt & Whitney PT6A-66B which gives more climb and cruise performance. The Avanti II is normally fitted out for five passengers.
I have flown Piaggios for six years. Best features- Fuel efficient- Roomy. Downside- Parts costs- Fickle steering system. That said- it has been very reliable. But when the time comes and something breaks- it can be costly. The PT-6 engines are bulletproof. Overall- great aircraft.
