Where is the wing anti-ice system applied?

The wing anti-ice system is designed to ensure safe operation of the aircraft in conditions where ice may build up on the wings, which can adversely affect lift and control. This system is applied specifically to the slats on the leading edge of the wings, which are the components most susceptible to ice formation during flight in freezing conditions.

The correct application of the anti-ice system is key to maintaining aerodynamic performance. By preventing ice accumulation on the outbound slats, the aircraft can achieve optimal airflow over the wing at high angles of attack, critical during takeoff, landing, and climb phases. Properly functioning slats enhance lift and control, especially in adverse weather conditions.

Other options are less accurate due to the specific function of the wing anti-ice system; the system does not operate on wing tips, which are generally less affected by airflow disruptions due to ice. Additionally, options referring to specific parts of the slats don’t convey the comprehensive coverage provided by the anti-ice system on the entire slat area along the leading edge.
