Abstract:
A landing gear assembly may include a first wheel and a second wheel, a first wheel sensor coupled to the first wheel and a second wheel sensor coupled to the second wheel, and a controller coupled to the first wheel sensor and the second wheel sensor. A tangible, non-transitory memory may have instructions for detecting a dragging brake. The controller may perform operations including receiving data from the first wheel sensor and the second wheel sensor, calculating a wheel speed characteristic for each of the first wheel and the second wheel based on the data, identifying a lowest value for the wheel speed characteristic, determining a moving average for the wheel speed characteristic, comparing the lowest value to the moving average, and whether the lowest value for the wheel speed characteristic indicates a dragging brake.
