The Remote and Digital Tower concept has the potential to liberate aerodrome Air Traffic Services (ATS) and act as an enabler for the modernisation and evolution of the service. Click here for a quick introduction to the concept.

Remote and Digital Towers is a concept that Think have helped to develop and one which, in recent years, has really been embraced by the industry. We are making these resources public in order to help share information on the concept, information on ongoing and future developments and also to provide our own insights.


Remote & Digital Tower Locations

To help to visualise the current uptake of Remote and Digital Towers and to create a helpful resource which the ATM community can use, we have created a ‘living map’

This unique dataset brings together sources from global ANSPs, airports and manufacturers to present the collective landscape of the concept. This information is presented as a map showing the past, current and future developments

The map shows the location of each target airport and provides a summary of information on the intended operation, the applicable ANSP and equipment manufacturer and other key information. The map is interactive, enabling you to focus on specific regions of interest or filter to focus on a selection.

We have used the pins to categorise each development according to its maturity as follows:

We hope to maintain this as a living information tool, providing a unique and independent view of Remote and Digital Towers worldwide, helping to reveal trends and track progress over time. All data is made openly available for industry benefit.

Our expertise and experience

Think have been central to the development of the Remote and Digital Tower concept to the point where almost every implementation and pre-implementation project uses inputs written by us as a starting point.  Think’s involvement in the concept began over 10 years ago in SESAR, contributing to tasks which set the baseline for Remote and Digital Tower.  Since then Think have provided Remote and Digital Tower consultancy services to ANSP projects in Europe, Australasia, and the Middle East and have provided a leading voice on Remote and Digital Tower working groups within EUROCAE and CANSO.

Think has experience of the systems proposed and a long and withstanding relationship with the main systems suppliers of Remote and Digital Tower technologies. This helps us to ensure a totally independent view on the concept and in addition puts Think in a unique position to advise and support our clients to make well informed decisions regarding their Remote and Digital Tower programmes.


Below is a set of information resources that we have produced which provide a conceptual history of Remote and Digital Tower operations together and take a look at the predictions we have made of the concept over the years. We also look to the future of the concept and provide insights into how the global pandemic may affect this outlook in the years to come.

Over the years, Think has made several predictions which look at the potential futures of Remote and Digital Tower, circulated in industry publications such as ATM magazine, International Airport Review and EUROCONTROL’S hindsight magazine. Here we look back at these and ask, “How accurate were we?” and to see if we now need to revise our outlook for the future.

By reflecting now in the midst of this crisis we also intend to understand where we are now, where we were heading and to provide a benchmark for the new future. In the years to come we hope to use this as a time capsule, a way to help us understand how much of an impact the global pandemic really had on the future of Digital Towers and did we see it coming.

Delving a little deeper we look at what the future may hold for the ANSPs and airports looking to implement Remote and Digital over the next few years when operating in the “new normal”.

We have asked leading manufacturers of Digital Tower technologies to share their insights, discussing how the current global crisis may shape the future for this concept.

At Think, we have been trying to understand the problem but also to think positively about how we can find a solution. We have also asked leading manufacturers of Digital Tower technologies to share their insights, looking at how the current global crisis may shape the future for this concept.

What Is Remote & Digital Tower?
What is a Remote and Digital Tower?

A remote or digital tower operation uses digital technologies to provide operators with a view of the aerodrome and its vicinity which can then be used as the primary means of visual observation. Typically, this is achieved using digital camera technology and other sensors, with the images transmitted over a network and relayed to the operator via screens.  This change means that operators conduct visual surveillance via digital means as their primary source, rather than using the traditional method of looking out of the window of the visual control room.

The use of the concept means that the aerodrome ATS can be provided from any location. Allowing the removal of the service provision from the physical confines of the aerodrome is what led to the conceptual term “Remote”.

From a regulatory perspective the implementation of a Digital Tower system is treated as a functional system change and not an operational change. This is an important distinction as, although there are functional differences between a Digital Tower and a conventional tower, the concept does not aim to change the nature of the ATS being provided, with levels of service and safety being maintained to at least equivalent levels.

Where has the concept come from?

The initial version of the concept emerged from Sweden over 10 years ago where there was a need for novel methods of providing ATS to low density and often isolated airports. To help support such operations the idea of providing a service from a more central location, where resources could be shared and used more efficiently and flexibly gave rise to the first versions of the concept.

The idea was that if the ANSP can select the location of the service provision then this can be in an area where it may be easier to source operational and support personnel. In addition, it means this facility can be used by more than one aerodrome, increasing the ability to share resources and costs.


Three primary operating concepts emerged from early R&D programs:

  • Single mode operations- refer to the provision of an aerodrome ATS to an airport.
  • Multiple mode operations- involve the provision of aerodrome ATS to two or more aerodromes simultaneously.
  • Contingency mode operations- refer to the provision of aerodrome ATS in cases where the permanent ATS facility is unusable; e.g. in non-nominal or business continuity events. As such the technical solution is not proposed as a permanent replacement to the conventional tower, which will still be the primary facility for ATS provision.


The scope of the concept is now seen to have expanded beyond the three core modes. The full scope of Digital Tower operations encompasses a range of operating modes.

Remote and Digital Towers is very broad concept with a wide range of different technical solutions. In fact the technical offering is becoming so broad that it has expanded well beyond the scope of the operational concept defined for Remote Tower (in SESAR), hence requiring the need for a wider and more structured operational concept definition (see our White Paper for further information).

The real potential is in the digitalisation

Although Digital Towers are not always the solution for an airport or ANSP’s operation, Digital Tower technology can enable wider network benefits. By digitalising the view of the aerodrome and its vicinity the door is open to allowing a range of other data and information to be visualised and presented to all the airport and ATM stakeholders. Its adoption is a positive move towards a truly digitalised network, one where the tower and its functions are able to connect to the wider ATM network and airport operations in a way not currently possible. Facilitating a more connected and ‘smarter’ ATM network.

Why Implement?

The traditional driver for Digital Tower implementation is cost efficiency. The concept proposes to provide a mechanism to reduce operating costs through enabling both lower total costs and by facilitating the sharing of resources. In addition to this remote and digital tower can bring a variety of other societal and economic benefits for a variety of stakeholders, including enhanced operational resilience, business continuity, improved operational flexibility and the potential to enhance performance by removing existing constraints, better supporting operators in their roles and even enhancing safety.
