What is meant by 'current aircraft memory items'?

The phrase 'current aircraft memory items' refers specifically to operating procedures that pilots are required to memorize and recall swiftly during critical situations in flight. These items typically include emergency procedures that are vital for the safe operation of the aircraft, ensuring that pilots can respond immediately without needing to reference checklists or manuals in high-pressure scenarios.

Memorizing these procedures is crucial because, when unexpected situations arise, such as system failures or emergencies, the ability to quickly access this information can significantly enhance safety and pilot effectiveness. This understanding underscores why it is essential for pilots to have these memory items internalized rather than relying solely on written resources, which may not be readily accessible during emergencies.

In contrast, the other options do not align with the definition of 'current aircraft memory items,' as they either refer to non-essential checklists, tangible items found on the aircraft, or visual aids that are meant to assist but do not directly pertain to the memorization of critical operational procedures.
