The invention provides a networked redundancy aircraft control system, and belongs to the technical field of aircraft control. According to the networked redundancy aircraft control system, multiple sets of similar or non-similar flight control computers are connected through a network by means of communication equipment in the system, comparison and decision making of control instructions are conducted by means of an arbitration unit on the network, and the appropriate instructions are selected to be output. In addition, in order to achieve supervision and redundancy processing of the arbitration unit, the system comprises a channel selection unit connected with the main flight control computer and the arbitration unit, the health states of the two units are judged according to heartbeatsignals of the arbitration unit and the main flight control computer, the reasonable instructions are selected according to the judgment result to control corresponding execution mechanisms, and meanwhile the units which work
