There is a theory I heard once called the Theory of Voice Relativity. It contends that how a person sounds on the radio is inversely proportional to how they look. I can't say it applies every time, but in my meager experience it has proven to be true more often than not.
I understand some private operators (Sask Gov't for one) operate their -350's single pilot. Does anyone know if you can operate a 1900C single pilot as well? Or was the C never certified for single pilot operation.
