The wing overheat warning message comes on after a failure of the wing anti-ice temperature controller causing the leading edge to overheat. When must the wing anti-ice be selected on in flight? WebAn anti-icing system must have a means of continuously delivering energy or chemical flow to a surface in order to prevent the bonding of ice. The typical thermal anti-icing system does this at significant energy expense. The concept is not viable for aircraft that do not have the requisite excess energy available during all flight phases. how to paint a bike wheel
