摘要： In an embodiment, an aircraft such as a rotorcraft (101) includes an actuator (401) and a flight control computer (205) interfaced with the actuator (401). The flight control computer (205) is configured to: increase an initiating force output by an initiating channel (403) of the actuator; stop the increasing of the initiating force in response to observing restraining forces on restraining channels (403) of the actuator; hold the initiating force at a quiescent initiating value while the restraining channels (403) hold the restraining forces at quiescent restraining values; increase the initiating force to a target initiating value while the restraining channels (403) increase the restraining forces to target restraining values; calculate a force fight test result by summing a difference between the target initiating value and the quiescent initiating value with differences between the target restraining values and the quiescent restraining values; and indicate the actuator failed verification in response to the force fight test result being greater than a first predetermined threshold.
