A 'dripstick' is a thin hollow tube installed vertically in the bottoms of
fuel tanks of many large
aircraft, used to check fuel levels. To read a dripstick, it is withdrawn from the lower surface of the
wing. When the top of the dripstick is withdrawn below the level of the
fuel, fuel enters the dripstick and drips through a hole in the cap. Graduations on the dripstick indicate the level of the fuel in the tank.
Newer aircraft use a
floatstick.
