What is the captain responsible for during DE/ANTI Icing?

The captain's responsibility during DE/ANTI Icing involves ensuring the safety and operational integrity of the aircraft, particularly in adverse weather conditions. Declaring an emergency and notifying the iceman or station is a crucial action because it allows the crew to communicate the severity of the situation and request the necessary assistance to manage ice build-up effectively.

This role as a leader in emergency situations encompasses not only safety management but also effective communication with ground support to initiate de-icing procedures. Keeping the plane free from ice is vital for maintaining proper aerodynamics and control, and the captain must take decisive action if ice poses a risk to flight safety.

While the other choices involve various operational tasks, they do not directly address the immediate safety priorities during icing conditions, which is why declaring an emergency and ensuring support is critical for the captain's role in this context.
