What types of issues can arise with electrically heated windshields?

Electrically heated windshields are designed to provide clear visibility during adverse weather conditions by preventing ice and condensation buildup. However, various issues can arise with these systems, particularly concerning their construction and operation.

The correct choice highlights specific concerns that can occur in electrically heated windshields, including arcing, which refers to the unintended electrical discharge that can occur if there is a fault in the heating element. Delamination occurs when the layers of the windshield can separate, leading to reduced structural integrity and clarity. Scratches can occur during the cleaning process or due to debris, compromising the performance of the windshield. Discoloration may happen over time due to exposure to UV light or thermal stress, affecting both appearance and visibility.

The other choices refer to conditions that are less specific to electrically heated windshields. For instance, while water leaks and corrosion may be relevant to the windshield installation or the aircraft structure, they are not direct issues tied to the operation of the electrical heating system. Electrical shorts and circuit overloads pertain more broadly to electrical systems as a whole, not solely to heated windshields. Fogging and condensation are typical concerns with any windshield but do not directly apply to the functionality of heating elements designed to prevent these very issues.
