Aircraft 1979 B55 Beechcraft Baron, unmodified
Company Private
Name Jack Showers
Date 03 Feb 2009
Groundspeed 266 kts
Notes

266 knots ground speed sustained for 13 minutes or so with excursions up to the low 280's.
I was on the way to a Beechcraft owners' function (BPPP) in Lakeland, FL from Lafayette, LA, at 15,000; straight, level and smooth.
These best ground speeds were from a straight downwind leg on a day after a cold front came raging through the Deep South.

The airplane is a stock, unmodified 1979 B55 Baron with IO-470L's. Photos of the steam gauges were taken about a half hour earlier on a more easterly heading and show the engine settings and indicated airspeed for the entire flight.
