You Cant Fly that Curve
When I learned IFR, the oddball technique for GA pilots was the DME Arc. These were the days of turn 10, twist 10, which was the best we had for approximating a curve using the straight-line navigation of VORs and slant-range distance. When GPS came on the scene, the box simply drew the magenta line in an arc and we, or George, followed it. An era was over.
