In the context of the A320 and its takeoff memo, a blue item indicates a checklist item that is designated "to be accomplished." This color coding serves as a visual cue for pilots, signaling that action needs to be taken or a specific procedure should be executed before proceeding with the flight. The use of blue in this context is standard across many aviation operators to enhance situational awareness and ensure all necessary preparations are completed in a timely manner.

This understanding is crucial during the pre-flight and takeoff phases, as pilots need to ensure that all checklist items are addressed properly to maintain safety and operational integrity. The distinction provided by the color coding helps streamline the process, making it clear which items still require the flight crew's attention.

In contrast, items that are complete or faulted would typically be indicated differently in the memo, serving to eliminate confusion and enhance clarity for essential actions during critical flight phases. Similarly, a test subroutine would imply that an item is in a testing phase, rather than being something that requires immediate attention for takeoff.
