Abstract
During a de-ice process, heating zones associated with a rotor may be supplied with power for shedding accreted ice from the heating zone. Priority heating zones associated with the leading edge of the rotor are supplied with power to activate the priority heating zones multiple times during the de-ice process. Heating zones associated with a lower surface of the rotor may be activated after the priority heating zones are first activated. A first dwell may be waited, to allow additional ice accretion on the priority zones. The priority heating zones may then be reactivated after the first dwell. Heating zones associated with an upper surface of the rotor may be then be activated. A second dwell may be waited, to allow additional ice accretion on the priority zones. The de-ice process may then repeat.
