ATPL: Concerning electrically powered ice protection devices, the only true statement is:
Domanda 505, Aircraft General Knowledge - Airframe, Systems, Powerplant - ATPL - Airline Transport Pilot license
| 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...). |
