What is the prop de-ice functionality in the T-54 aircraft?

The prop de-ice functionality in the T-54 aircraft is designed to heat all eight propellers simultaneously, which is crucial for preventing ice accumulation that can adversely affect performance and safety during flight. This integrated heating system ensures that all props are uniformly treated, providing consistent operational reliability and effectiveness.

By heating all the propellers at once, the system enhances the aircraft's performance in potentially icy conditions by preventing ice from forming on the blades, which can disrupt airflow and reduce lift. This proactive approach is essential for maintaining optimal aerodynamics and ensuring the safety of the flight, especially in environments where icing conditions are prevalent.

The other options do not accurately reflect the capabilities of the prop de-ice functionality, as they imply limitations or conditions that are not characteristic of the T-54's design.
