My last check ride in an Aztec D found me on one engine, in an unusual attitude, wth no panel except a compass, vertical speed indicator, and an ADF. I was told to find my position and navigate to the closest airport with a suitable length runway.

Out came my stop watch, slide wheel, pencils, and paper charts.
