What indication shows that too many symbols are selected for display on the ND MAP?

The indication that shows too many symbols are selected for display on the Navigation Display (ND) MAP is "EXCESS." This term specifically signifies that the number of symbols being requested for display exceeds what the system can accommodate at one time. When this situation occurs, it typically leads to clutter on the display, potentially impairing the pilot's situational awareness. Recognizing "EXCESS" allows pilots to adjust their settings to enhance the clarity of the information presented on the ND, ensuring critical data is readily accessible and reducing the likelihood of information overload.

Other choices such as "INSUFFICIENT," "OVERLOAD," or "LIMITED" do not accurately reflect the specific condition of exceeding the display capacity relating to the number of symbols; rather, they may refer to different operational statuses or limitations not specifically tied to symbol display on the ND MAP.
