Classification: CPC B | IPC B

Claim 0:
1. A control surface actuation system comprising:
a first actuator;
a second actuator;
a first drive arm coupled to a control surface;
a second drive arm coupled to the control surface;
a cam;
memory;
machine-readable instructions; and
processor circuitry to execute the machine-readable instructions to:
cause the first actuator to generate an output to operatively couple the first actuator to the first drive arm, the first actuator to drive movement of the cam to cause the first actuator to couple with the first drive arm;
cause the second actuator to generate an output to operatively couple the second actuator to the second drive arm;
cause the first actuator and the second actuator to move the control surface when the first actuator is operatively coupled to the first drive arm and the second actuator is operatively coupled to the second drive arm;
detect the first actuator in a failed state; and
in response to the detection of the first actuator in the failed state,
cause the first actuator to refrain from generating the output to disrupt the operative coupling between the first actuator and the first drive arm; and
cause the second actuator to move the control surface via the first drive arm and the second drive arm.
