Zusammenfassung:	There is provided an ice protection system (151) for a rotary aircraft, including a rotor blade (130) susceptible to an ice buildup having an inboard portion (141) and an outboard portion (145), the length (L1) of the inboard portion (141) and the length (L2) of the outboard portion (145) define a total length (L3) of the rotor blade (130); a first deicing system (153) coupled to the inboard portion (141) of the rotor blade (130), the first deicing system (153) including a plurality of spanwise zones (157); and a second deicing system (155) coupled to the outboard portion (145) of the rotor blade (130), the second deicing system (155) including a plurality of chordwise zones (165). In one aspect, there is provided a deicing system for a rotary aircraft. In another aspect, there is a method to de-ice a rotor blade of an aircraft.
