SYSTEME DE SURVEILLANCE ET D'ALARME POUR AERONEF

摘要

The system has a diagnostic unit (210) receiving signals e.g. speed measurement signal, from sensors (C1-Ck) and determining values of state variables from the signals. The variables describe configurations of failure of elements of an aircraft and systems composed of the elements. A calculation unit (220) calculates a cost function from the values and cost values stored in a database (240). The function describes a loss of operational capacity of the aircraft for an operational function. An input/output interface (230) presents characteristic information of the loss of the capacity.
