Abstract: A method of characterizing and counting violations of a threshold by an operating parameter of an aircraft engine of an aircraft includes detecting, by the aircraft, a violation of the threshold by the operating parameter while the aircraft engine is in operation. The method also includes, on detecting the violation, automatically transmitting from the aircraft to a ground system a warning message about the violation. Further, the method includes, on the basis of the warning message, automatically determining a severity level for the violation. In addition, the method includes incrementing a counter representing a number of occasions the operating parameter of the aircraft engine has presented a violation corresponding to the severity level.

Abstract: The method of the invention for characterizing and counting violations of a threshold by an operating parameter of an aircraft engine, comprises: a detection step of the aircraft detecting a violation of the threshold by the parameter while said engine is in operation; on detecting this violation, a transmission step of the aircraft automatically transmitting to a ground system a warning message about the violation; on the basis of this message, a step of automatically determining a severity level for the violation; and an incrementation step of incrementing a counter representing the number of occasions the operating parameter of the engine has presented a violation corresponding to said severity level.

Abstract: An additive for thermoplastic materials is prepared to achieve controlled degradation and the manufacturing of very light coloured thermoplastics. The thermoplastics may be processed by film blowing, extrusion and injection molding. A ferric(III) salt is reacted with a C2o-C24 fatty acid or derivative under formation of a fat-soluble ferric (III) compound in a process where a suitable oxidizing agent ensures that all the iron in the end product is maintained in the ferric state.
