An avionics system with a common sensor detector that includes analog sensors for sensing flight parameters of an aircraft and for providing sensor signals indicative of the flight parameters. Avionics computers compute flight parameter data associated with the sensor signals from the analog sensors. A primary flight display receives, processes, and displays the flight parameter data. The primary flight display includes inside limit data comparators to compare the flight parameter data from at least a same pair of flight computers to indicate a common sensor fault condition when the flight parameter data difference is zero or approximately zero for a predetermined period of time. Other safety critical systems may employ the common sensor detector.
