An apparatus for preventing untimely braking, which apparatus is specially adapted to an electromechanical brake including at least one actuator having a pusher suitable for being moved by an electric motor controlled by a control module so as to press a stack of disks in controlled manner, The apparatus is provided with a power switch disposed on a power line for powering the electric motor of the actuator, the power switch being controlled by a control logic circuit that places the power switch by default in an open state, and that places the power switch in a closed state only in response to a braking confirmation signal not coming from the control module of the actuator and independent therefrom.

Apparatus for preventing untimely braking in a brake having electromechanical actuators

The invention relates to a method of managing a braking system architecture for an airplane fitted with brakes having electromechanical actuators, in which some of the actuators are connected to a battery assembly of the airplane and other actuators are not connected to the battery assembly of the airplane, which method comprises a step of controlling at least one of the actuators that is not connected to the battery assembly to cause it to exert a force equal to a unit holding force, which force is determined independently of any braking demand from the pilot. The invention also provides an architecture specially adapted to implement the method.
