I don't have an opinion one way or another about the Piaggio Avanti, I'm sure it's a fine plane. I'm one those guys who always looks up when hearing airplane noise. Yesterday, while in Pacific Grove, CA and about 3 miles from KMRY I heard a much louder than normal turboprop departing (high) overhead and before I glanced up knew what it was. Those who say the Piaggio is only louder during the approach are wrong. "Loudest" perhaps but still quite raucous during climb out.
