METHOD AND DEVICE FOR DETECTING NOISE ON A GUIDE SIGNAL OF LOC TYPE RECEIVED BY AN AIRCRAFT
First Claim
1. A method in an aircraft for detecting the presence of noise in a signal of LOC type, this method being characterized in that it comprises the following steps,estimation of a first lateral speed (105) of the said aircraft according to a first set of parameters;
- estimation of at least one second lateral speed (120) of the said aircraft according to at least one second set of parameters, among which at least one parameter is of different nature from each parameter of the said first set of parameters;
comparison of the said first lateral speed and of the said at least one second lateral speed according to a threshold (500);
detection of the presence of noise in the said signal of LOC type if the difference between the said first lateral speed and the said at least one second lateral speed is greater than the said threshold.

Abstract
The invention has as an object a method and a device for an aircraft for detecting noise in a signal of LOC type. A first step consists in estimating a first lateral speed (105) of the said aircraft according to a first set of parameters. Concurrently, at least one second lateral speed (120) of the said aircraft is estimated according to at least one second set of parameters, among which at least one parameter is of different nature from each parameter of the said first set of parameters. A second step consists in comparing the said first lateral speed and the said at least one second lateral speed according to a threshold. If the difference between the said first lateral speed and the said at least one second lateral speed is greater than the said threshold, the presence of noise in the said signal of LOC type is detected. Advantageously, an additional step of validation of the said detection of noise in the said signal of LOC type is implemented. Similarly, according to a preferred embodiment, a step of validation relating to the said first and at least one second lateral speed is implemented,
