1. A control system including:

  • first and second control columns for receiving pitch and roll control inputs from a pilot for an aircraft, each control column having a control grip moveable along a pitch axis to adjust the pitch control input to the aircraft and moveable along a roll axes to adjust the roll control input to the aircraft;

    a roll interconnect rod operably coupling the first and second control columns for coordinated movement of the control grips along each control grips roll axis when an input is provided to either of the control grips; and

    a pitch interconnect rod operably coupling the first and second control columns for coordinated movement of the control grips along each control grips pitch axis when an input is provided to either of the control grips;

    further including a disconnect device interposed between the grip of the first control column and the grip of the second column for a selected one of pitch or roll, the disconnect device having a coupled state fixedly coupling the grips for coordinated movement along a selected one of the pitch axis or roll axis and a decoupled state in which the disconnect device does not fixedly couple the grips such that movement of one grip along the selected one of the pitch axis or roll axis is not translated to the other grip, the disconnect device including a solenoid actuated latch for transitioning the disconnect device from the coupled state to the decoupled state.
