What is an active air traffic control frequency?

An active air traffic control frequency refers to a specific radio channel designated for communication between pilots and air traffic controllers. This frequency facilitates essential communications during different phases of flight, including taxiing, takeoff, cruising, and landing. It allows air traffic controllers to provide critical instructions, air traffic advisories, and clearances to pilots, thus ensuring safe and efficient aircraft operations.

This frequency differs from other types of radio channels such as those used solely for emergency communications or casual social interactions among pilots. It is not limited to just takeoff and landing situations, as it is vital throughout the entire flight, allowing for real-time communication and updates regarding air traffic conditions, weather, and navigational instructions. Understanding the function of an active air traffic control frequency is crucial for pilots to maintain situational awareness and adhere to air traffic control guidelines.
