What occurs during a configuration test if all items are correctly set for takeoff?

When all configuration items for takeoff are set correctly, the indication of the configuration test changes from "T.O. CONFIG -- TEST" in cyan to "T.O. CONFIG -- NORMAL" in green. This transition signifies that the aircraft systems have validated that all necessary conditions for a safe takeoff configuration have been met, indicating that the aircraft is ready for takeoff. The green indication is particularly important as it communicates to the flight crew that the configurations—such as flap settings, slat positions, and other critical parameters—are correctly established for the takeoff phase, thus assuring them that it is safe to proceed.

In contrast, other scenarios might involve no change, continued cyan indication, or even an alarm sounding if configurations were not set properly, but in this case, a successful and correct configuration leads to a positive confirmation via the indication change to green.
