I live about five miles due north of a very busy GA airport, just off the extended centerline of the main runway, 17-35. So I hear most aircraft that land. I can tell when it is a P180 when I hear one is landing, by hearing it and hearing it, and really hearing it as it passes overhead.
By using just my hearing, it sounds about twice as loud as a Kingair 200-350 and a lot nosier than a Turbo-Commander. Also, I have spent many a day in Aspen sitting around the airport waiting for passengers and have watched them takeoff in the summer time.
Damn it seems like they use a lot of runway both landing and taking off, a lot of runway.
westhawk, did you ever operate a P-180 out of ASE? I'm kind of curious on what kind of load and range you had in the summertime.
