The costs of providing air traffic services are high and need to be reduced, especially at low and medium density airports. Control towers are relatively expensive to build and maintain, but the services they provide can be vital to rural and regional communities. Since the first remote tower services gained certification in 2015 in Sweden, several projects have been launched - including some which envisage a controller maintaining situational awareness for more than one airport at a time. SESAR has already delivered a solution enabling remote tower service provision to two low-density airports. Building on this, the latest SESAR research aims to test the feasibility of multi remote tower operations in airports with high traffic volumes.

In order to enable more airports, or high traffic volume, to be controlled simultaneously from a multiple remote tower module (MRTM), the work aims to validate advanced features of the visual information displayed to controllers and to integrate additional voice services in the module.

The candidate solution assumes that a controller can hold endorsements for up to three different airports, and addresses all types of airspace users including general aviation, rotorcraft, and remotely piloted aircraft systems. In addition to limiting the number of airports that can be operated in parallel, the controller can split one airport between different tower modules in case of traffic overload, or degraded mode. Furthermore, to meet the increased traffic, a planning tool for the controller is envisaged to help manage the increased complexity, tailored to suit different applications.
