DEVICE AND METHOD FOR THE RESIDUAL ANALYSIS OF A RESIDUUM TO DETECT SYSTEM ERRORS IN THE SYSTEM BEHAVIOR OF AN AIRCRAFT

Document Type and Number:

WIPO Patent Application WO/2010/125080

Kind Code:

A3

Abstract:

The present invention provides a device and a method for the residual analysis of a residuum to detect system errors in the system behavior of an aircraft. The device for the residual analysis of a residuum comprises an apparatus to generate the residuum at least dependent on the reference variable and the system output variable, a comparator unit to provide an analytical result by comparing the residuum to a given threshold, a first unit to provide a constant threshold portion, a second unit to provide an adaptive threshold portion at least dependent on the reference value, which can change over time, and a third unit to provide the threshold by linking the constant threshold portion to the adaptive threshold portion.
