1. A linear electromechanical servocontrol comprising a power rod that is able to move in translation,
wherein the servocontrol comprises a single linear electrical actuator provided with at least one electric motor connected by a mechanical link to the power rod, the servocontrol comprising an anchor secured to the electrical actuator, the at least one electric motor being controlled by a computer, the anchor having an anchoring rod that is able to move in translation in relation to a body of the servocontrol, the anchor having at least one anchoring brake that is configured to immobilize the anchoring rod with respect to the electrical actuator in a normal operating mode and render the servocontrol transparent by allowing the electrical actuator to move in relation to the anchoring rod in a safe operating mode at the request of the computer.
