Abstract
The detecting means (1) comprise measuring means (2) adapted to measure and provide at least one raw data corresponding to an aircraft parameter, computing means (3) adapted to estimate at least one derivative of said raw data, and detecting means (4) adapted to detect a failure with the aid of said derivative, said computing means (3) being adapted to estimate said derivative by differentiation.

Method for detecting a fault on an aircraft,
- wherein it comprises the following successive steps, which are implemented in an automated and repeated manner and consist in:
- a) receiving at least one datum depending on a parameter measured by a sensor, said datum being noisy,
- b) estimating a derivative of said noisy datum by differentiation, on the basis of said noisy datum;
- and
- c) detecting a fault on the basis of at least this estimated derivative.
Device for detecting a fault on an aircraft, comprising:
- measuring means (2) adapted to measure and transmit at least one noisy datum corresponding to an aircraft parameter;
- computing means (3) adapted to estimate at least one derivative of said noisy datum;
- and
- detecting means (4) adapted to detect a fault on the basis of said derivative;
- wherein said computing means (3) are adapted to estimate said derivative by differentiation.
