TRANSFORMING ATM WITH REMOTE TOWERS AND SWIM

Remote-control towers and SWIM technology offer cost-effective solutions for managing small airports, enhancing data sharing, efficiency, and scalability while aligning with global aviation standards, explains DR. ARJUN SINGH

The remote-control tower concept emerged in 2001 to manage operations at far-flung remote airports where permanently deploying manpower is not viable. In December 2019, Sweden inaugurated a new airport without a traditional ATC tower, making it the first airport to rely solely on a virtual tower. This system was developed by SAAB. The integrated system operated from a central airport, where all flight-related data is accessible to control operations at remote airports. Meanwhile, discussions began about operationalising remote airports with limited flights. Developing conventional ATC towers and providing ATS services may not be cost-effective, as revenue generation from RNFC, landing, and parking charges is expected to be very low.

In 2008, Boeing introduced the concept of System Wide Area Management (SWIM) to the Ajay Prasad Committee as a new approach for the remote operation of airports. Leveraging state-of-the-art technology and highspeed data networks, SWIM provides a single access point for near real-time, relevant, and reliable aeronautical, flight, weather, and surveillance information. It delivers the infrastructure, standards, and services necessary to optimise the secure exchange of critical data across designated airspace and the aviation community.

As high-speed digital data-sharing underpins NextGen, SWIM enhances both operational efficiency and innovation. This concept is particularly scalable, as it reduces costs and minimises the need for trained manpower. The development of SWIM infrastructure and services should align with a globally accepted operational concept that defines the anticipated benefits, enablers, features, and principles for its development and transition.
