An actuation system (2) comprises a plurality of actuators (10), a common power drive unit (12) for driving the actuators (10) and a transmission line (14) transmitting drive from the common drive unit (14) to the plurality of actuators (10). A clutch (24) is arranged in the transmission line (14) between the power drive unit (12) and the plurality of actuators (10) for selectively disconnecting the power drive unit (12) from the plurality of actuators (4). At least one sensor (26) is provided for sensing an abnormal load condition in the actuation system (2). The at least one sensor (26) is operatively coupled to a clutch control (28) which is configured such that when the at least one sensor (26) senses an abnormal load condition, the clutch control (28) is operative to disengage the clutch (24) so as to disconnect the power drive unit (12) from the plurality of actuators (10). A brake (20) is operative to brake the actuators (10) upon disengagement of the clutch (24).
