| 20080215194 | FORMULATION OF A PREVENTIVE MAINTENANCE MESSAGE RELATING TO THE FUNCTIONAL DEGRADATIONS OF AN AIRCRAFT - A method of preventive maintenance is disclosed for an aircraft. The aircraft includes components, including items of equipment of the aircraft and/or electronic modules and/or physical links. The lifetime information for the components is known. The aircraft also includes means for monitoring the components, a centralized maintenance system, and means for estimating the life time of the components. The aircraft carries out a set of functions, each being ensured by a chain of components. The method comprises several steps including, a first step of locating the degradations of the items of equipment, a second step making it possible to allocate the located degradations to the various functions of the aircraft, a third step of estimating the lifetime of the functions identified in the second step, and a fourth step of formulating the maintenance message constructed on the basis of the previous steps. | 09-04-2008 |
| 20080249678 | Aircraft Failure Diagnostic Method and System - The present invention relates to an aircraft failure diagnostic method and system. The method includes one configuration phase defining the possible correlations between the detectable faults. Each of these correlations are associated with data pertinently describing the circumstances of the malfunction and appropriate failure-repair operations. A phase of correlating the detected fault is performed phase of recovering the data describing the circumstances of the malfunction and a phase of determining failure-repair operations is then performed. | 10-09-2008 |
| 20080269982 | Fault Validation Method and System for Aerodynes - The present invention relates to a fault validation method and system for aerodynes. The method includes at least a configuration step associating with each detectable fault equipment units for which a copy of memory segments is to be made. Verification tests to be performed include a step for copying memory segments and a step for verifying equipment units. | 10-30-2008 |
| 20080304418 | MAINTENANCE SYSTEM FOR A SET OF EQUIPMENT - The invention relates to a maintenance system for a set of equipment of an aircraft, forming a physical network ( | 12-11-2008 |
| 20090140910 | METHOD AND A SYSTEM FOR FILTERING TRACKS ORIGINATING FROM SEVERAL SOURCES AND INTENDED FOR SEVERAL CLIENTS TO WHICH THEY ARE SUPPLIED - The present invention concerns a method and a system for filtering tracks originating from several sources and intended for several clients to which they are supplied. | 06-04-2009 |
| 20090292951 | METHOD AND DEVICE FOR FAULT LOCATION IN A SYSTEM - The invention relates to a method and a device for locating a fault in a system. The system includes a set of elements. The elements are connected in a network. Each element is associated with an operational status and a probability of failure. The method according to an embodiment of the invention includes, for each of the elements having a status indicating a malfunction, denoted as a defective element, the creation, from the system topology, of an expression comprising terms corresponding to functional elements connected to said defective element. If several expressions have been created in the preceding step, then merge expressions having at least one term in common. For each expression, delete terms in the expression corresponding to elements having a “healthy” status. Calculate a minimal expression from the preceding expression. Calculate failure probabilities for selected members of the minimal expression based on failure probabilities of the corresponding elements. Calculate the location of the fault to the elements corresponding to the members of the minimal expression for which the ratio of failure probabilities to exposure time is greater than a threshold. | 11-26-2009 |
| 20090306838 | METHOD AND DEVICE FOR AIDING THE MAINTENANCE OF A SYSTEM - The invention relates to a method for aiding the maintenance of a system, the system comprising a set of networked elements, the system being accompanied by indications defining subsets of networked elements E | 12-10-2009 |
| 20100010708 | Methods of Identifying Flight Profiles in Aircraft Maintenance Operations - The method of identifying a flight profile of an aircraft, the aircraft including a centralized maintenance system and an item of equipment including a component designed to measure the environmental conditions, comprises:
