Abstract
An aircraft control system has a flight specification acquisition sensor for acquiring flight specifications of an aircraft and outputting the respective numerical values, and a plurality of flight computers, each having the same control software and performing airframe control based on the flight specification numerical values, thereby constituting a redundant system of flight control functions. Further, the control system includes a noise generator for the plurality of flight computers, which generates a plurality of noises different from each other, and the plurality of noises are individually superimposed on the numerical value of one flight specification output from the flight specification acquisition sensor to generate a plurality of new flight specification numerical values different from each other which are then output to the plurality of flight computers. This configuration ensures redundancy of the aircraft control software against potential bugs using the same control software.
