A method and a device for activating an automatic piloting mode of an aircraft are disclosed. The device can include means for engaging an automatic pilot mode, when (i) the current distance of the aircraft with respect to a reference position on the ground belongs to a determined distance range, and (ii) the current height of the aircraft is at most equal to a reference height associated to the automatic pilot mode.

The invention concerns a cathode pulverization target characterized in that its active part, i.e. the volume of the target capable of being removed during the cathode pulverization, consists of a high purity aluminum alloy simultaneously containing copper and iron and having simultaneously a recrystallization temperature well above 20° C. and an electric resistivity less than 2.85 &mgr;&OHgr;.cm at 20° C. The use of the target for making bonding circuits reduces the frequency at which voids and hillocks appear, while maintaining the resistance of the bonding circuits at values comparable to the resistance obtained with a high purity aluminum alloy, while also providing the etching characteristics comparable to those of high purity aluminum alloy.

A process is provided for ultrasonic testing the internal soundness of cathode sputtering targets including an active part made of very pure aluminum or of very pure aluminum alloy. In particular, this process, after the choice of an ultrasound sensor functioning at an operating frequency greater than 5 MHZ, and preferably between 10 and 50 MHZ, and adjustment of the appropriate measurement sequence, using a target immersed in a liquid and having certain artificial defects simulating the decohesions in the target, consists of taking a count in terms of size and number of the internal decohesions per unit volume and of selecting the targets with a decohesion density of .ltoreq.0.1 decohesion larger than 0.1 mm per cm.sup.3 of active metal of the targets, and preferably less than 0.1 decohesion larger than 0.04 mm per cm.sup.3 of active metal. The process also pertains to selecting precursors of the cathode sputtering targets, containing less than 0.1 internal decohesion larger than 0.04 mm per cm.sup.3.

摘要:
A method of aiding the piloting of an airplane ensures the availability of an automatic pilot and a thrust regulation system on board the airplane. To this end, the method includes determining first information by measuring the actual airspeed of the airplane, and this first information is used to control the automatic pilot and the thrust regulation system in a primary mode during normal operations of the airplane. When the first information is lost by becoming unavailable or unreliable, the automatic pilot and the thrust regulation system are each controlled in a secondary mode by control parameters determined using additional flight data independent from the actual airspeed of the airplane and the first information. Consequently, an alternative or redundant control is supplied for ensuring the continued operation of an automatic pilot without necessary intervention from crew members on board the airplane.

The system embodying the invention involves a communications instrument comprising a sensitive surface coupled to a processor ensuring management of a plurality of display elements, the dialogue between said instrument and said processor taking place according to a sequence comprising a first operational mode in which the sensitive surface is virtually divided into a plurality of zones corresponding isomorphically with the geometrical disposition of the display elements, and a second operational mode in which a variable displayed on a visualisation element is modified subsequent to displacement of the operator's finger on the sensitive surface. This system is notably suitable in the case of management of a large number of display elements and is highly ergonomic.
