1. A method of processing an error when performing a predetermined avionics procedure, the method being carried out automatically by a detection and alert system of an aircraft, the method comprising:

  • monitoring the operation of one or several avionics device(s) of the aircraft, the monitoring based on tracking a sequence representative of the predetermined avionics procedure being carried out;

    detecting a break of the sequence due to an incorrect command and/or due to a skipping of at least one expected command according to the predetermined avionics procedure being performed;

    retrieving at least one piece of information representative of the break in the sequence; and

    monitoring the operation of one or several avionics device(s) of the aircraft corresponding to the monitoring of real-time states of the avionics device(s);

    the detecting comprising a comparison of the real-time states of one or several avionics device(s) of the aircraft with at least one of the following elements;

    a set of prohibited states, associated with the predetermined avionics procedure, and stored in a first dedicated memory space, anda set of expected states, based on the performance moment of the sequence representative of the avionics procedure, the set of expected states being stored in a second dedicated memory space;

    when the comparison of the real-time states and the set of prohibited states is positive, the retrieved representative information corresponds to a first alert comprising a first triplet of data respectively representative of;

    the predetermined procedure,the detected prohibited state from among the real-time states, anda command to be performed recommended to offset the detected prohibited state,or wherein the monitoring of the operation of one or several avionics device(s) of the aircraft corresponds to the monitoring of commands received in real time by the avionics device(s), and wherein the detecting comprises a comparison of the commands received in real time with a set of expected commands, based on the performance moment of the sequence representative of the predetermined avionics procedure, the set of expected commands being stored in a third dedicated memory space.
