Abstract

A system for automatically and simultaneously diagnosing apparatus performance and safety condition, maintaining on-apparatus components and sub-systems, and reporting apparatus condition and maintenance action taken during apparatus refueling. Diagnostic sub-systems include means for determining the condition of fluids or components that are consumed or deteriorate during use. Maintenance sub-systems include means for replacing, replenishing or renewing non-fuel fluids or components that are consumed or deteriorate during use. Reporting sub-systems include means for communicating information between on- and off-apparatus sub-systems and for generating reports that document apparatus performance and safety condition and the maintenance actions taken during refueling. A report can be presented to the apparatus operator, apparatus maintenance technician and/or to a central reporting facility. The report can be used to identify existing or potential apparatus system/sub-system or component failure, to schedule needed repair, to certify regulatory compliance, to optimize the performance of the apparatus, apparatus sub-system or operator, or to manage the cost of apparatus operation.
