Abstract: A method of measuring a height of a fuel surface of fuel in an aircraft fuel tank. One or more images of the fuel surface are captured, each image including a fuel surface line where the fuel surface meets a structure. Each image is analysed in order to determine a height of the fuel surface line at three or more points in the image. If the fuel surface line is not a straight line, then an average angle of the fuel surface line can be determined from the points in the image by spatial averaging. Preferably a series of images of the fuel surface are captured over a time period, and an average height of the fuel surface is determined from the series of images by time averaging. The height of the fuel surface line(s) at three or more points is used to determine a volume of the fuel, a mass of the fuel, and/or an attitude of the fuel surface.

Abstract translation: 一种测量飞机燃料箱中的燃料表面的高度的方法。 捕获燃料表面的一个或多个图像，每个图像包括燃料表面满足结构的燃料表面线。 分析每个图像以确定图像中三个或更多个点处的燃料表面线的高度。 如果燃料表面线不是直线，则可以通过空间平均从图像中的点确定燃料表面线的平均角度。 优选地，在一段时间内捕获燃料表面的一系列图像，并且通过时间平均从该系列图像确定燃料表面的平均高度。 在三点以上的燃料表面线的高度用于确定燃料的体积，燃料的质量和/或燃料表面的姿态。

Abstract: An aircraft comprising a Rubens' tube for distributing gas within the aircraft. The Rubens' tube comprises a tube with a plurality of outlets; an inlet for feeding the gas into the tube; and a loudspeaker arranged to set up a standing acoustic wave within the tube. Typically the Rubens' tube is arranged to feed inert gas into a fuel tank of the aircraft.
