A method for determining a throttle position of an aircraft, the method comprising: obtaining a first throttle position from a first sensor, a second throttle position from a second sensor, and a third throttle position from a third sensor, the first, second, and third sensors (221, 222, 223) separately coupled to a throttle of the aircraft for obtaining independent throttle position measurements therefrom; and determining a difference between the first throttle position and the second throttle position; detecting a mismatch when the difference between the first throttle position and the second throttle position exceeds a threshold; characterised in that the method further comprises: in response to detecting the mismatch, selecting a valid one of the first throttle position and the second throttle position based on the third throttle position, wherein selecting the valid one of the first throttle position and the second throttle position comprises: determining a first throttle position difference between the first throttle position and the third throttle position and determining a second throttle position difference between the second throttle position and third throttle position; and selecting the first throttle position as the valid one when first throttle position difference is smaller than the second throttle position difference and selecting the second throttle position as the valid one when the second throttle position difference is smaller than the first throttle position difference; and outputting a signal indicative of the throttle position based on the valid one of the first throttle position and the second throttle position. obtaining a first throttle position from a first sensor, a second throttle position from a second sensor, and a third throttle position from a third sensor, the first, second, and third sensors (221, 222, 223) separately coupled to a throttle of the aircraft for obtaining independent throttle position measurements therefrom; and determining a difference between the first throttle position and the second throttle position; detecting a mismatch when the difference between the first throttle position and the second throttle position exceeds a threshold; characterised in that the method further comprises: in response to detecting the mismatch, selecting a valid one of the first throttle position and the second throttle position based on the third throttle position, wherein selecting the valid one of the first throttle position and the second throttle position comprises: determining a first throttle position difference between the first throttle position and the third throttle position and determining a second throttle position difference between the second throttle position and third throttle position; and selecting the first throttle position as the valid one when first throttle position difference is smaller than the second throttle position difference and selecting the second throttle position as the valid one when the second throttle position difference is smaller than the first throttle position difference; and outputting a signal indicative of the throttle position based on the valid one of the first throttle position and the second throttle position. in response to detecting the mismatch, selecting a valid one of the first throttle position and the second throttle position based on the third throttle position, wherein selecting the valid one of the first throttle position and the second throttle position comprises: determining a first throttle position difference between the first throttle position and the third throttle position and determining a second throttle position difference between the second throttle position and third throttle position; and selecting the first throttle position as the valid one when first throttle position difference is smaller than the second throttle position difference and selecting the second throttle position as the valid one when the second throttle position difference is smaller than the first throttle position difference; and outputting a signal indicative of the throttle position based on the valid one of the first throttle position and the second throttle position.
