Final answer:
The cockpit windows that are electrically heated and/or anti-fogged are usually the front windscreen and side windows.
Step-by-step explanation:
In modern aircraft, the cockpit windows that are electrically heated and/or anti-fogged are usually the front windscreen and side windows.
Electric heating elements are embedded in these windows to prevent ice formation or fogging. Automatic systems detect ice or fog and activate the heating elements.
Anti-fogging features, such as a thin transparent layer of conductive material, can also be used to prevent fogging in certain weather conditions, ensuring clear vision for the pilots.
