Before entering an active runway, contacting whom is essential?

Contacting the control tower or airfield control authority before entering an active runway is essential because these entities are responsible for overseeing all aircraft movements on the airfield, ensuring safety and coordination among all operations. The control tower provides vital information about runway status, any active operations, and guidance on when it is safe to enter the runway. This communication helps prevent unauthorized or unsafe runway incursions that could lead to dangerous encounters with aircraft that are taking off or landing.

The control tower serves as the central point through which all air traffic is managed, making it critical for anyone, including drivers and operators, to confirm their safety and obtain clearance before proceeding onto an active runway. This ensures adherence to established protocols and contributes to overall airfield safety.
