Which part of the airfield is not visible from the Control Tower?

The section of the airfield that is not visible from the Control Tower is typically referred to as the Charlie LOLA. Control Towers have an expansive view of the airfield; however, certain areas may be obscured due to physical structures, terrain, or the specific layout of the airfield. In this case, the Charlie LOLA is designed in such a way that it often lies out of the direct line of sight from the Control Tower, which makes it challenging for air traffic controllers to monitor that area visually. Understanding the visibility and surveillance limitations of different zones is critical for safe airfield operations.
