Abstract: A method for evaluating a rate of change of a failure between a first unit type and a second unit type of an avionic system, the method taking into account, for each aircraft comprising the unit type, the number of flights made and the number of fault messages associated with the failure.

Abstract: A method for measuring a level of wear of a tire of a vehicle, the tire comprising a tread in which are hollowed out furrows. The method comprises: positioning a system, called tire inspection system, at a predefined position with respect to the tire; acquiring at least two images of the tread by using at least one image acquisition system included in the system, each image representing a different point of view on the tread; calculating a three-dimensional representation of the tread from each image acquired; determining at least one profile of the tread representative of depth variations on the tread; calculating a value representative of a depth of the furrows of the tread; determining information representative of a level of wear of the tire as a function of the value.
