What is the primary function of anti-ice systems?

The primary function of anti-ice systems is to prevent ice from accumulating on critical surfaces of the aircraft, such as wings, engines, and control surfaces. Ice buildup can severely impact the performance and safety of an aircraft by altering its aerodynamics, increasing weight, and obstructing airflow over the surfaces. By utilizing heating elements or other methods, anti-ice systems ensure that ice does not form, thereby maintaining the necessary lift and control during flight in icy conditions.

Maintaining proper aircraft performance by preventing ice accumulation is crucial for safe operations, especially in environments where icing is a concern. Other aspects of aircraft performance, such as fuel efficiency, speed, and maneuverability, may be indirectly influenced by the effectiveness of anti-ice systems, but they are not the primary purpose of these systems.
