Abstract
A method of operation is provided during which an electric motor of an aircraft is powered using a power supply. The power supply includes a plurality of power strings electrically coupled in parallel. The powering includes: outputting string electricity from each of the power strings; and outputting supply electricity from the power supply. A plurality of string parameters are measured using a sensor system. Each of the string parameters is indicative of an electrical parameter of the string electricity from a respective one of the power strings. The string parameters are added together to provide a total string parameter. A supply parameter is measured using the sensor system indicative of the electrical parameter of the supply electricity. Operability of the sensor system is evaluated based on the total string parameter and the supply parameter.
