Method and device for automatically estimating an aircraft flight parameter vector, as well as methods and assemblies for detecting a failure affecting such a vector

摘要

The method involves receiving values observed from explanatory values, where the explanatory values represent a parameter of an aircraft (AC). A coefficient vector is estimated on an observation window for determining a linear relationship between the parameter vector and the explanatory values, where the relationship is relative to a linear modeling by implementing a partial least squares (PLS) regression. The estimated coefficient vector is used to calculate an estimated value of the parameter vector from the linear modeling. The estimated value is transmitted to a user unit. Independent claims are also included for the following: (1) a device for automatically estimating a flight parameter vector used by an aircraft system of an aircraft (2) a method for automatically detecting failure affected by a flight parameter vector used by an aircraft system (3) a method for automatically detecting a malfunction of sensors in an aircraft (4) an automatic detection assembly for detecting failure affected by a flight parameter vector used by an aircraft system (5) an automatic detection assembly for detecting a malfunction of sensors in an aircraft.
