What is the maximum bank angle limit when flying with ice accumulation?

The maximum bank angle limit when flying with ice accumulation is 30 degrees. This limit is set due to the reduced aerodynamic performance and control effectiveness of an aircraft when it has ice on its wings and control surfaces. Ice alters the airflow around the aircraft, increasing drag and causing a decrease in lift.

Maintaining a bank angle of 30 degrees or less helps ensure that the aircraft can maintain controlled flight and respond more effectively to pilot inputs. At greater bank angles, the risk of stalling increases, particularly in conditions where the efficiency of the wings is already compromised by ice. Therefore, adhering to a maximum bank angle of 30 degrees is a crucial safety measure for pilots operating in icy conditions to prevent a loss of control.
