On Modern Aeroplanes, Electrically Powered Thermal Devices Are Very Efficient, Therefore They Only Need Little Energy.
On modern aeroplanes, electrical power supply being available in excess, this system is very often used for large surfaces de-icing.
On modern aeroplanes, electrically powered thermal devices are used as de-icing devices for pitot- tubes, static ports, windshield...
On modern aeroplanes, electrically powered thermal devices are used to prevent icing on small Surfaces (pitot-static, windshield...).
