Abstract
A device for controlling a rudder of an aircraft has at least two servo-systems each including at least one electric control input. At least one of the servo-systems is a mixed servo-system that also has a mechanical control input. When an engine fault occurs, an electric control system causes at least two of the servo-systems to simultaneously operate the rudder. When the electric control system is not operational due to an electric fault, the mixed servo-system operates the rudder based on control signals from the mechanical control input.
