1. A device for monitoring aircraft control information, the control information generated by at least two different flight management systems onboard an aircraft, comprising:
- at least one computer external to said flight management systems and comprising a comparison unit that includes a first element for computing the differences, in twos, between control information originating from each of said flight management systems and a second element for comparing each of the differences with at least one predetermined threshold value; and
a warning system connected to said computer that generates a warning signal when at least one of said differences is greater than said threshold value, and that comprises at least one primary flight display generating a warning signal in the form of a change of bars relative to a flight director system, that are displayed on the primary flight display.
