    Abstract: The present disclosure relates to a diagnostics system (2) for a vehicle (1). The diagnostics system (2) comprises a plurality of application functions (10) for controlling functions of the vehicle, a plurality of I/O interface modules (30) hosting drivers for I/O devices associated with the application functions (10), and a vehicle diagnostics manager or VDM (20). The I/O interface modules (30) are configured to transmit output signals pertaining to operation of their associated I/O devices to the application functions (10) together with a signal tag identifying the I/O interface module that generated the output signal. Each I/O interface module (30) is also configured to run physical fault monitors in order to detect physical faults for its associated I/O devices, and to maintain a fault record of detected physical faults. Each application function (10) is configured to run strategic fault monitors in order to detect strategic faults for its associated vehicle function. The application functions (10) are configured, upon detection of a strategic fault, to identify the signal tag associated with the output signal that caused the detection of the strategic fault, and to report the detected strategic fault to the VDM (20) together with the associated signal tag. The VDM (20) is configured, upon receiving a notification of a detected strategic fault from an application function (10), to identify a source I/O interface module (30) in dependence on the received signal tag, to read physical faults from the identified source I/O interface module (30), and to triage the physical faults from the identified source I/O interface module (30) with the reported strategic fault in order to identify a cause fault for the reported strategic fault.

    Abstract: A method of in-flight operational assessment for an electric aircraft comprising detecting by a sensor an electrical parameter of an energy source. The method further includes receiving by a controller the electrical parameter from the sensor and determining a power-production capability of the energy source, using the electrical parameter. The method further includes calculating, by the controller, a projected power-consumption need of the electric aircraft and comparing the determined power-production capability of the energy source to the projected power-consumption need. The method further includes displaying, by a graphical user interface, an element of the power-production capability of the energy source.
