Abstract: Method of formulating a statistical model for predetermining the workload of an aircraft pilot (20), in particular of an aircraft of commercial type, as a function of objective flight parameters, in which in the course of at least one flight, real or simulated, of the aircraft, the pilot of the aircraft is required, in flight phases and under flight conditions and under determined pilot conditions, constituting the flight parameters, to provide a grade for his workload by means of a pre-established scale. This grade is recorded at the same time as the corresponding flight parameters and simultaneously the value is measured of data indicative of the said flight parameters. Finally, a statistical correlation is established between the graded values of the workload on the one hand, and the abovementioned data and the flight parameters on the other hand. 
<??>Application to the certification and development of an aircraft and to the training, improvement and checking of performance levels and to the monitoring of an aircraft pilot's level of adaptation to a new aircraft.

Abstract: This invention relates to an ozone generator for generating ozone by carrying out corona discharge between electrodes opposed each other in air. This ozone generator is intended to make compact the apparatus as a whole and to simplify its maintenance by reducing the number of its accessories. To this end, blades are formed by one of the electrodes while a casing is formed by the other electrode so that the blades and the casing constitute a blower. According to this structure, any separate blower for sequentially supplying fresh air to a corona discharge field and for sequentially extracting the generated ozone becomes unnecessary.

Abstract: A method for etching titanium nitride local interconnects is disclosed. A layer of titanium nitride is formed as a by-product of the formation of titanium silicide by direct reaction; this layer of titanium nitride is present over the titanium silicide layer, as well as over insulators such as oxide. A plasma etch using CCl₄ as the etchant is used to etch the titanium nitride anisotropically, and selectively relative to the titanium silicide due to the passivation of the titanium silicide surface by the carbon atoms of the CCl₄. Excess chlorine concentration may be reduced, further reducing the undesired etching of the titanium silicide, by providing a consumable power electrode, or by introducing chlorine scavenger gases in the reactor. The plasma may be ignited by exposing the gases to a mercury/argon light source, photodetaching electrons from the anions in the gas.

Abstract: A pulverised fuel and air mixture is burnt in conditions giving relatively low NO x  emissions by using a burner which has concentric passages (30,32,34) for a primary air-fuel mixture and secondary and ternary air flows respectively. In the passage (30) for the primary air-fuel mixture guide elements (48) are provided at angularly spaced positions. The elements (48) are arranged to deflect the flow in the passage (30) and so produce regions of high fuel concentration. Downstream of the guide elements and adjacent the outlet (38) of the passage (30), flow disturbing members (50) are provided in angularly spaced positions to modify the flow pattern of the air-fuel mixture at the passage outlet. The members (50) assist stabilisation of the flame front at the burner outlet and complement the action of the guide elements (48) in promoting combustion conditions that lead to low NO x  emissions.
