Abstract: A method for transmitting flight parameters of a lead aircraft to an intruder aircraft. Transmission includes a collision avoidance system connected to which is a flight parameter transmission authorization system having a database including coordinates defining a volume of confidence smaller than the monitoring volume. The flight parameter transmission authorization system of the lead aircraft authorizes, only for an intruder aircraft identified as flying within the volume of confidence, transmission of at least one flight parameter of the lead aircraft, such that this intruder aircraft is able to calculate the position of centers of wake vortices generated by the lead aircraft or the flow strength of the wake vortices. Exchanging flight parameters of the lead aircraft only with intruder aircraft flying within the volume of confidence with limited dimensions makes it possible not to exceed the maximum capacity of the bandwidth of the automated communication.

Abstract: A thrust reverser system includes two thrust reversal cascades, of which the first cascade is entrained by an actuator, and which are configured to adopt a retracted position in which they are housed in a space located outside the duct. The action of the actuator brings about: rearward displacement of the first cascade in the direction of a nacelle opening; and during part of the rearward displacement of the second cascade, simultaneous pivoting of this second cascade under the action of a control lever, the interaction of which with a fixed guide rail forces the front end of the lever to move radially inwards while the lever is entrained rearwards by the second cascade.

Abstract: A pump health monitoring system for an aircraft fuel pump. The health monitoring system compares environmental data to a reference environment and captures pump data when the environmental data matches the reference environment. The pump data captured is therefore normalized to the reference environment. A pump remaining useful life is calculated from the normalized pump data.

Abstract: A device for shaping a semi-finished fiber product for manufacturing a C-shaped or I-shaped former, and including clamping mechanisms and a forming tool. Each clamping mechanism has a first and a second clamping element and together they hold a semi-finished fiber product along two longitudinal and opposite edges.

During this movement, the longitudinal edges of the semi-finished fiber product are transformed into a curved shape, wherein a length of one of the longitudinal edges of the semi-finished fiber product does not change and a length of the other longitudinal edge becomes greater. During the movement, the forming tool is transformed into a curved shape and guided relative to the clamping elements against the semi-finished fiber product such that the semi-finished fiber product is deep drawn over the forming tool.
