Dispositif de fiabilisation de la mesure d’une sonde de Pitot par prise en compte de l’évolution des conditions opérationnelles et environnementales

Abstract : Safety is the primary consideration in the air transportation sector. According to various accident reports, it seems that 75% of these accidents are related to human factors such as pilots, air traffic controllers, maintenance managers and even design engineers. This study is derived from an aeronautic problem defined following the crash of the Airbus 330 in the Rio-Paris flight, in 1 June 2009. Investigations concluded that the accident was due to the aircraft’s pitot tubes failure, after which the crew reacted incorrectly. In order to overcome the problem of Pitot sensors measurements inaccuracy and incoherence, we propose a technical solution which consists in setting up a fourth retractable probe to assess the Pitot sensors measurement accuracy during the flight. The implementation of this new technical solution implies a need to know the different variables that can affect the Pitot sensors measurements quality. From these variables, it is possible to model the Pitot sensors measurements quality degradation. Subsequently and thanks to these models, periodic and sequential inspection policies are proposed by considering the measurement quality degradation as a decision criterion. Optimization of these inspection policies will be carried out using numerical procedures or meta-heuristics. The current research work aims to propose an original contribution for operational safety of Pitot sensors
