What must be done regarding the GPD Map during setup?

Centering the GPD (Ground Power Display) Map and setting the desired range is critical during the setup process because this action ensures that the radar system is appropriately configured to provide accurate and relevant situational awareness. By centering the map, operators can focus on the area of interest or concern, which is essential for identifying and tracking objects effectively. Setting the desired range allows users to modify how far out the radar will scan for targets, tailoring the display to specific operational needs. This customization is crucial for effective monitoring and decision-making, especially in dynamic environments where conditions and priorities can change rapidly.

The other options, while relevant in different contexts, do not directly address the initial and essential step of preparing the GPD map for proper situational awareness and target tracking during setup. Adjusting altitude settings, opening displays, or clearing previous data may enhance functionality but do not impact the immediate necessity of having the map centered and set to the appropriate range for effective operation.
