I’ve done relatively little scud-running over the years. That’s mainly because I earned an instrument rating at about the same time I started using personal airplanes more and more for transportation rather than recreation. It’s difficult to say which came first—the utility an instrument rating affords or the need to use an airplane for personal transportation—but in my case, the two developed at about the same time. My most memorable scud-running flight involved flogging a Skyhawk between Columbus, Ga., and Knoxville, Tenn., one summer afternoon. Writing about it now, I don’t recall the exact reason I determined getting an IFR clearance wasn’t the way to go, but that’s the decision I made. I presume it had something to do with either the airplane or the weather.
