What is a Remote Tower?

Remote Towers represent a breakthrough in air traffic management (ATM), enabling control of air traffic at airports from remote locations. Traditionally, air traffic services (ATS) are conducted from physical control towers at the airport. Remote Towers allow air traffic controllers to manage operations through high-resolution camera systems, advanced surveillance technology, and digital communication systems from distant control centers.

This concept, initially adopted by smaller airports with lower traffic volumes, has evolved and, as of 2021, has been implemented in international airports in locations like London and Norway. The introduction of remote towers has opened doors to digital towers, an advancement that integrates a wide array of ATM systems and data for enhanced air traffic operations.


How Do Remote Towers Work?

Remote towers rely on a combination of high-speed cameras, digital displays, advanced communication systems, and software applications to replicate the view and capabilities of a traditional tower. Here’s a step-by-step explanation:

  1. Video Surveillance: High-definition cameras capture panoramic and zoomed-in views of the airport. This video footage is transmitted in real time to a remote control center.

  2. Digital Display and Data Integration: The video feeds, along with radar and flight data, are displayed on digital screens in the control center. Operators see real-time visuals and data, allowing them to make informed decisions.

  3. Communication Systems: Remote towers maintain constant communication with pilots and ground staff through secure, high-speed communication links. This includes both voice and text communication.

  4. Advanced Software and AI Integration: Many remote towers employ artificial intelligence (AI) for tasks like collision avoidance, traffic flow management, and even weather monitoring. This digital transformation enables remote towers to enhance safety and efficiency in air traffic control.
