I was wondering what is the smallest aircraft to have a CVR (Cockpit Voice Recorder) and/or FDR (Flight Data Recorder)?
Small single engine prop can sometimes have the avionics, like the G1000, that records some of the flight parameters on a memory card. But what about a proper CVR or FDR?
I'm not asking about military aviation, but more about general or small commercial airplanes.
I understand that it depends of the type of operation, but what is the smallest airplane to have a CVR/FDR on board?
