A de-icing assembly includes an aircraft with an airfoil. A de-icer is disposed on a leading edge of the airfoil. A tab extends from the de-icer in an aft direction from an aft edge of the de-icer. The de-icer and the tab are adhesively attached onto an outer skin of the airfoil. A supercooled large droplet sensor is built into the tab. The supercooled large droplet sensor is positioned in a location aft of the aft edge of the de-icer.
