Fixed wing aircraft electric heating ice prevention/control method

The invention provides a fixed wing aircraft electric heating ice prevention/control method comprising the following steps: dividing each slat in the leading edge into a plurality of heating zones along a spanwise direction; arranging a plurality of heating elements from the outer side to the inner side of the slat in each heating zone; controlling the plurality of heating zones to heat in cycle in sequence; controlling the heating elements in the heating zones to work in a work sequence so as to realize heating in a staggering manner, thus uniformly heating each heating zone. The control method can prevent and control ice formation, can effectively reduce system power consumption, thus improving aircraft fuel economic property.
