What is the maximum time limit for maintaining a bank angle of 30 degrees with ice accumulation?

The maximum time limit for maintaining a bank angle of 30 degrees with ice accumulation is 30 seconds. This is critical information for pilots operating in conditions where ice may form on the aircraft. The presence of ice affects the aerodynamic properties of the aircraft, such as lift and drag, which means that steep bank angles can lead to a higher risk of stalling or losing control.

Maintaining a bank angle of 30 degrees for longer than the specified time can increase the likelihood of these adverse effects, particularly if the aircraft's performance is degraded due to the added weight and altered shape of ice accumulation on the wings and control surfaces. Therefore, the 30-second limit serves to mitigate the risks associated with reduced performance and loss of control that could arise from prolonged banking in icy conditions. Understanding this limitation is essential for ensuring pilot safety and effective aircraft handling when encountering ice.
