If symbols appear in the upper left of the ND MAP format, what has been selected for display?

When symbols appear in the upper left of the Navigation Display (ND) in MAP format, it indicates that certain information related to navigation and situational awareness has been selected for display. The correct answer reflects that data such as NAVAIDs (Navigational Aids), airports, and other related navigation information are visible to the pilot. This enhances the pilot’s ability to navigate and manage the flight by providing critical information about nearby facilities and navigational support points.

The upper left display is specifically tailored to show data that assists the pilot in understanding their immediate environment and planning their next actions appropriately. This information is vital for safe and effective navigation during flight operations, especially in complex environments.

In contrast, the other options reference different sets of information that may not necessarily be relevant or displayed prominently in the upper left of the ND. Each of those groups pertains to different aspects of flight parameters or tactical considerations that would be shown elsewhere on the display or under different circumstances.
