A device used in an aircraft with an electrical flight control system to reduce load applied to the wing during a lateral roll maneuver, by comparing a roll control with a threshold, and filtering a control. As a result of this action on the roll control, resulting load increases on the wing can be anticipated and reduced. Loads can thus remain below a maximum design value for the wing if the applied roll control is too high for planned use of the aircraft, therefore limiting overdesign of the wing.

The invention claimed is: 1. A method for reducing loads on a structural element of an aircraft due to a control parameter comprising:comparing the parameter with a threshold value of the parameter;when the parameter is less than or equal to the threshold value, applying a control value to the device corresponding to the control parameter;when the parameter exceeds a threshold value:filtering the difference between the parameter and the threshold value using a low-pass filter with a first time constant, andapplying a control order to the device corresponding to the sum of the filtered difference and a control value corresponding to the threshold value.
