Chennai airport’s Air Traffic Control department marked World Air Traffic Controller Day on Tuesday with cultural programmes and seminars, highlighting the operational role of controllers in keeping aircraft movements safe and orderly as India’s aviation network expands.
The observance was held on October 20, the day recognised internationally to acknowledge the contribution of air traffic controllers to aviation safety. Air traffic control services began internationally 104 years ago, while ATC operations at Chennai airport commenced in 1932 and have now completed 94 years.
Union Civil Aviation Minister Ram Mohan Naidu addressed the Chennai gathering virtually from Delhi. He said Indian air traffic controllers manage an airspace of approximately 2.8 million square nautical miles, nearly three times the country’s land area.
Controllers work throughout the year to coordinate aircraft movements and protect the safety of thousands of aircraft using Indian airspace, according to the minister. Their responsibilities include managing passenger aircraft, cargo flights, medical air ambulances and helicopters within designated airspace.
The minister said air traffic controllers also play a role in maintaining efficient aircraft movements and enabling flights to operate smoothly while avoiding unnecessary delays. Their work involves coordinating aircraft movements in the air and around airports, where the timing and sequencing of flights are central to safe operations.
The demands on the ATC system are increasing as more people choose air travel, new airports are established and aircraft technology develops. The rising number of flights is also increasing the volume of traffic that controllers must monitor and coordinate across India’s airspace.
Naidu emphasised that the physical and mental fitness of air traffic control officers is essential to safe operations. Their fitness is assessed daily as well as at specified intervals, and the assessments are mandatory to ensure that officers remain fit to perform their duties whenever they are called upon to work.
At an airport, ATC functions as a critical operational layer connecting runways, aircraft and airspace. Controllers regulate and coordinate movements so that different types of aircraft can operate safely within assigned areas. The system’s responsibilities extend beyond passenger services to include cargo operations, emergency medical flights and helicopters.
The Chennai event placed the airport’s long operating history within this wider aviation system. With ATC operations dating back to 1932, the airport’s control function has continued through changes in aircraft, airport infrastructure and the scale of air travel. The minister’s remarks focused on the need for controllers to maintain safety and operational efficiency as those demands grow.
