In the coming years, airspace will become increasingly busy – despite the present pandemic-related downturn. Scheduled and charter flights and the rising use of drones are greatly increasing the challenges for safety and communication systems. It is currently estimated that drone traffic will grow by 14% a year. In order to manage the entire airspace, conventional towers operated by air traffic controllers need to be supplemented by remote towers, which use artificial intelligence to manage air traffic at airports from a different location.
