Controlled airspace refers to specific areas in the sky where air traffic control (ATC) services are available. This service is crucial for both Instrument Flight Rules (IFR) and Visual Flight Rules (VFR) flights. The term encompasses various classes of airspace, namely A, B, C, D, and E. Each class has its own set of regulations and requirements. Within controlled airspace, you’ll find Control Areas, Terminal Control Areas, Airways, and Control Zones. These structured environments help ensure safe and efficient air travel. Understanding how controlled airspace works is essential for pilots and air traffic controllers alike.
