What is a key reason for notifying ground control of any unusual activities on the airfield?

Notifying ground control of any unusual activities on the airfield is primarily aimed at promoting safety and preventing potential incidents. The airfield is a highly active environment where aircraft operations must be conducted safely and efficiently. Unusual activities could indicate potential hazards, unauthorized personnel, or equipment that could interfere with normal operations. By informing ground control, they can take appropriate action—such as adjusting traffic control, alerting other personnel in the area, or investigating the situation—to mitigate risks associated with those unusual activities. This communication helps maintain a safe environment for all users of the airfield, including pilots, ground personnel, and vehicles, ultimately preventing accidents and ensuring a smooth operational flow.
