1. A method of managing ice accretions on an aircraft, the method comprising:
determining an icing condition of the aircraft; and
performing a propeller modulation based on the icing condition, wherein performing the propeller modulation comprises:
modulating a first propeller parameter of a first set of one or more propellers of the aircraft in coordination with a modulation of a second propeller parameter of a second set of one or more propellers of the aircraft,
wherein the first propeller parameter and the second propeller parameters are different parameters, each comprising one of: revolutions per minute (RPM), blade pitch angle, electric engine torque, propeller tilt angle, or propeller angular position about a propeller blade rotation axis, of the corresponding first or second set of one or more propellers.
