Several months ago I mused about the how ever-advancing computer technology has led to a marked improvement in simulators for the light GA market. Reader Keith Smith later alerted me to a corresponding service he had developed called PilotEdge. His company’s mission is to add a level of realism to the general aviation FTD that not even the multi-million dollar Level D boxes have thus far been able to offer. I was intrigued. What could possible transform an inexpensive Flight Training Device that way? In a word: radios.
