The presence of a green memo serves as an indicator that a system operation is functioning temporarily and within normal parameters. In the context of the A320's aircraft systems, green memos are typically used to represent normal conditions and expected operational statuses. When a system is operating correctly and as intended, it may display a green memo, offering reassurance to the crew that everything is functioning as it should.

This visual cue plays a crucial role in the cockpit environment, where the ability to quickly assess the status of various systems can directly affect decision-making and operational safety. Following standard protocol, green memos indicate routine, healthy function, contrasting with other color codes that signify warnings or faults.

The other visual cues, such as white memos, amber alerts, and red signals, convey different statuses; for instance, amber alerts often suggest caution or a non-normal condition that requires attention, while red signals typically indicate a critical issue that could jeopardize safety. Therefore, the role of a green memo as a signal of normal, reliable operation is what makes this answer the correct choice.
