What is the consequence of turning on the Wing Anti-ice system without visual confirmation?

When the Wing Anti-ice system is activated without visual confirmation, it can lead to increased operational risks. This is primarily because the system might not be effectively addressing the necessary conditions for anti-icing. If the anti-ice system is inadvertently left on for an extended period without confirmation of ice presence or the appropriate conditions, the minimum application time required increases. This means that the system could remain active longer than necessary, leading to potential overheating or other malfunctions.

In some aircraft systems, activating wing anti-ice could potentially lead to slats icing over and other complications; however, the minimum application time requirement is specifically impacted by a lack of visual confirmation. It emphasizes the necessity of checking the external conditions before engaging such systems to maintain operational safety and efficiency.
