CPC B64C13/12

CPC B64C13/12 is a technology classification for patents about pilot-operated "dual control apparatus" for aircraft control or transmitting systems.

The usual meaning of "dual control" is a control system where an experienced pilot and a pupil, sitting together, can each control the aircraft. That is a common meaning now, and it was also relevant at the time of early aero. There appear to be other meanings -- perhaps a control by either hand or foot pedal, or control by a pilot and by automatic or remote control means.
