Full Form of ACZ
What is ACZ?
An Aerodrome Control Zone (ACZ) is a designated volume of controlled airspace established around an airport, extending from the surface to a specified upper limit. In India, the Airports Authority of India (AAI) manages these zones to ensure the safe and orderly flow of aircraft arrivals, departures, and ground movements. The ACZ is a critical component of air traffic management—pilots must obtain clearance before entering and strictly follow instructions from the aerodrome control tower. It is used at all major Indian airports such as Delhi, Mumbai, and Bengaluru, and is referenced in the Civil Aviation Requirements (CARs) issued by the Directorate General of Civil Aviation (DGCA). For students pursuing pilot licenses or air traffic control (ATC) training, understanding ACZ boundaries and procedures is essential for DGCA exams and practical flying. The zone helps prevent collisions and integrates with larger airspace structures like Terminal Manoeuvring Areas (TMA) and Flight Information Regions (FIR). In everyday operations, the ACZ is where ground control, local control, and approach services coordinate closely to manage traffic density, especially during peak hours. Its role is vital for aviation safety and efficiency in India's growing civil aviation sector.
