Boots are automatically cycling at the optimum time to assure proper ice
removal. Correct operation of the system can be checked observing the
corresponding green advisory light illumination at each boot inflation
impulse. If correct operation cannot be confirmed, do not enter or leave as
soon as possible icing conditions.
Apply ”LEADING EDGES DEICING FAILURE” emergency procedure.
