What infrastructure is essential for managing aircraft operations at an airport?

The control tower is essential for managing aircraft operations at an airport because it serves as the central hub for coordinating all air traffic in and around the airport. Air traffic controllers stationed in the tower are responsible for ensuring the safe and efficient movement of aircraft during takeoff, landing, and while taxiing on the ground. They communicate directly with pilots and provide critical information regarding weather conditions, runway availability, and other necessary details to maintain safety and order within the airspace surrounding the airport.

While other options like the hangar, terminal building, and ramp play important roles in supporting airport operations—such as providing maintenance, passenger services, and aircraft parking—the control tower is specifically focused on overseeing the real-time operations of flights, making it fundamental to the safe management of aircraft activities.
