Assessment of the Technical Condition of the Aircraft Fuel System by Its Main Elements in Flight

The serviceability of the aircraft's on-board systems have to be monitored in flight. Each on-board system has a built-in control, but it is hard to control condition of the entire avionics on-board in flight. The issue of organizing health monitoring and test algorithms for the on-ooard maintenance system is considered. The algorithm is implemented using Mamdani's fuzzy logic. First, the condition of the main elements of the aircraft's fuel system is evaluated, and then the flawless function of the fuel system as a whole is constructed. Using fuzzy logic eliminates the need to work with accurate input data and allow to operate inaccurate data.
