A floatstick is a device to measure fuel levels in modern large aircraft. It is made up of two tubes, one enclosed within the other, around which is a ring-shaped float that contains a magnet. There is also a magnet attached to the top of the floatstick. The floatstick is withdrawn from the bottom of the wing until the magnets stick, indicating the level of the fuel.
