Abstract

Systems and methods for determining a throttle position of an aircraft are described herein. A first throttle position is obtained from a first sensor, a second throttle position is obtained from a second sensor, and a third throttle position is obtained from a third sensor. The first, second, and third sensors are separately coupled to a throttle of the aircraft for obtaining independent throttle position measurements therefrom. A difference between the first throttle position and the second throttle position is determined. A mismatch is detected when the difference between the first throttle position and the second throttle position exceeds a threshold. A valid one of the first throttle position and the second throttle position is selected based on the third throttle position, in response to detecting the mismatch. A signal indicative of the throttle position is outputted based on the valid one of the first throttle position and the second throttle position.
