FIELD: aircraft engineering.
SUBSTANCE: proposed system comprises a pair of transparent sheets (8) held apart and facing each other with the help of intermediate transparent layer (14) and resistive coating (20) arranged between aforesaid sheets. Proposed system incorporates also inverter (22) to feed AC square- or quasi-square signal (34) to aforesaid resistive coating (20). Said signal received, coating (20) emits heat to reduce or rule out water or ice accumulation of aircraft windscreen.
EFFECT: reduced weight and higher efficiency.
