Relational database for maintenance information for complex systems
First Claim
1. A relational database for relating maintenance information that differs for each of a plurality of complex systems using a common database structure so as to facilitate maintenance procedures for the plurality of complex systems, the relational database comprising:
- a plurality of primary entities for providing a fault model description of each of the plurality of complex systems, said fault model description including, for each of the plurality of complex systems, failure modes, symptoms and data required to effect a repair; and
a categorical entity corresponding to a complex system that enables selection of the fault model description corresponding to the complex system.

Abstract
A relational database is for relating maintenance information that differs for each of a plurality of complex systems, such as a plurality of differing aircraft, using a common database structure so as to facilitate maintenance procedures for the plurality of complex systems. The database structure comprises: a plurality of primary entities for providing a fault model description of each of the plurality of complex systems, the fault model description including, for each of the plurality of complex systems, failure modes, symptoms and data required to effect a repair; and a categorical entity corresponding to a complex system, such as an aircraft, that enables selection of the fault model description corresponding to the complex system or aircraft. The relational database is particularly suited for use in or by an aircraft maintenance and diagnostic system that assists with fault correction for a fault condition within an aircraft based on a fault model for the aircraft.

12. A relational database for relating maintenance information that differs for each of a plurality of complex systems using a common database structure so as to facilitate maintenance procedures for the plurality of complex systems, the relational database comprising:
-
a categorical entity corresponding to a complex system that enables selection of a fault model description corresponding to said complex system; and
a plurality of primary entities for providing said fault model description corresponding to said complex system selected according to said categorical entity from a plurality of fault model descriptions of the plurality of complex systems, said plurality of fault model descriptions including, for each of the plurality of complex systems, failure modes, symptoms and data required to effect a repair;
wherein said plurality of primary entities facilitate classification of a fault condition and then fault isolation and repair procedures to correct the fault condition. - View Dependent Claims (13, 14, 15, 16)

17. An aircraft maintenance and diagnostic system for assistance with fault correction for a fault condition within an aircraft based on a fault model for the aircraft, the system comprising in combination:
-
a user interface;
a computer, coupled to the user interface, having a processor and memory for storing software instructions and a relational database;
said processor executing said software instructions to process information to facilitate the identification and correction of the fault condition within the aircraft according to a fault model defined by said relational database;
said relational database for relating maintenance information that differs for each of a plurality of aircraft using a common database structure so as to facilitate maintenance procedures for the plurality of aircraft, the relational database comprising;
a plurality of primary entities for providing a fault model description of each of the plurality of aircraft, said fault model description including, for each of the plurality of aircraft, failure modes, symptoms and data required to effect a repair; and
a categorical entity corresponding to the aircraft that enables selection of the fault model description corresponding to the aircraft. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
