Which windows are heated for both anti-ice and anti-fog protection?

1. Side windows only

2. All windows

3. Forward windows only

4. Rear windows only

The correct answer is: Forward windows only

The correct answer is that only the forward windows are heated for both anti-ice and anti-fog protection. Forward windows include the windshield and other forward-facing panes that are crucial for pilot visibility. Heating these windows helps to eliminate ice and prevents fogging, which is particularly important in maintaining clear vision during flight, especially in adverse weather conditions where moisture can cause significant visibility issues. The side and rear windows typically do not have the same level of heating implemented for these purposes due to design considerations and operational necessities, as they are less critical to the pilot's forward visibility. Their functionality is often more focused on providing structural integrity and minimizing weight, rather than extensive anti-ice and anti-fog capabilities. Hence, they may not be heated or only equipped with minimal solutions for those specific issues.
