Electrical anti-ice is applied to which of the following?

The correct response indicates that electrical anti-ice is applied to the flight deck windows. This is an important function because ensuring clear visibility for the pilots is critical for safe operation, especially in adverse weather conditions where ice can form on the windows. The electrical heating system is designed to prevent ice accumulation and maintain windshield clarity, contributing to the overall safety and effectiveness of the flight crew’s operations.

In the context of the A320 aircraft, understanding where anti-ice systems are applied helps crews manage the aircraft's systems effectively during various phases of flight, particularly in winter or icy conditions. The emphasis here is on maintaining safety and operational efficacy within the cockpit environment, which is vital for decision-making and navigation.

Other choices, while they may involve anti-ice systems, do not specifically involve electrical anti-ice for the flight deck windows. Therefore, recognizing that electrical anti-ice is utilized on the flight deck windows highlights the specific focus on pilot visibility and the critical role it plays in flight safety.
