Is it true that the ice light switch only illuminates the leading edge of the left wing?

The assertion that the ice light switch illuminates both wings is accurate. The function of the ice light system is to enhance visibility on both the left and right wings, allowing pilots to better assess the condition of the wings during icing conditions. This is crucial for ensuring safety as it provides a clearer view of any ice accumulation that could affect aircraft performance and handling.

The other choices suggest limitations or inaccuracies concerning the ice light switch's functionality. A choice indicating it is a single-pilot operation feature suggests a restriction that does not encompass the system’s full capability. A claim of a delay in illumination could imply a malfunction or operation characteristic that isn't typically associated with this system. Lastly, the option stating that it does not illuminate at all is incorrect, as the primary purpose of the ice light is to provide illumination for safety in icy conditions.
