Beschreibung
Zusammenfassung:	A method for monitoring at least two aircraft wheel electromechanical braking actuators. For each electromechanical actuator, the method includes first determining a current value representative of the power supply current of the electromechanical actuator and determining a reference current value estimated from the power supply currents of at least one other electromechanical actuator. Then, the representative current value and the reference current value are compared. Any abnormal operation of the electromechanical actuator is detected when the difference between the representative current value and the reference current value is above a predetermined threshold.
