Abstract: To reduce the bulk of the acquisition systems embedded onboard an aircraft and dedicated to predicting failures, an acquisition system is provided comprising an avionics rack and at least one recording device, in which the avionics rack comprises a front panel provided with at least one test connector configured to be connected to all or some of the data buses of the aircraft, each recording device comprises a housing and an acquisition port, the acquisition port being provided on an outer face of the housing, the acquisition port of each recording device is engaged with a corresponding test connector of the avionics rack, each recording device is configured to acquire at least some signals applied to the acquisition port by the corresponding test connector, and to store the acquired signals.

Abstract: A method for arranging a set of antennas capable of transmitting or receiving in a radio frequency range in an existing aerodyne implemented either during an initial installation operation, or in a subsequent maintenance or update operation is disclosed. The method includes removing at least one component of a structural element external to the bearing surface of the existing aerodyne, the component being substantially transparent to the radio frequency range; installing the set of antennas in a zone exposed by the removal in the step; fitting an electronic and electrical harness connecting the set of antennas to a radio communications system and to a power supply inside the fuselage; re-forming the external structural element in such a way as to cover the installed set of antennas.

Abstract: A tray for an avionics bay, comprising a body and a recording device rigidly connected to each other in order to reduce the space requirement of acquisition systems on board an aircraft and dedicated to the prediction of failures. The recording device comprises a first input/output port to be connected to the avionics bay, a second input/output port to be connected to an item of electrical equipment, a data bus for routing signals between the first and the second input/output port, a collection member configured for acquiring at least some of the signals routed by the data bus between the first and the second input/output port, and a memory configured to store the signals acquired by the collection member.
