Claim 6:
7. A spoiler control method applicable to an aircraft including left and right spoilers provided on left and right main wings, when driven by an actuator, each spoiler being movable between a basic position positioned on a same plane as a corresponding one of the main wings and a deployed position on a plane tilted relative to the corresponding main wing, the spoiler control method comprising steps of:
detecting whether the left and right spoilers irregularly move toward the deployed position;
obtaining angles formed by the left and right spoilers relative to the main wings and determining whether a difference between the obtained angles of the left and right spoilers is equal to or less than a specified value; and
outputting a retracting signal designed to move the left and right spoilers back to the basic position,
wherein, based on the irregular movement being detected in a given one of the left and right spoilers, the signal outputting step outputs the retracting signal for the given one of the spoilers and refrains from outputting the retracting signal for the other of the left and right spoilers, and if the difference between the angles of the left and right spoilers becomes equal to or less than the specified value, the signal outputting step outputs the retracting signal for the other of the left and right spoilers.
