Cross-border air navigation services


Maastricht Upper Area Control Centre

Performance through innovation.

Cross-border air traffic management


The Maastricht Upper Area Control Centre (MUAC) manages the upper airspace (from 24,500 to 66,000 feet) over Belgium, the Netherlands, Luxembourg and north-west Germany - one of Europe’s busiest and most complex airspace areas.

We are pioneers in the delivery of customer-focused, reliable and impartial air traffic management services.

We are the only cross-border civil-military air navigation service provider in Europe and have played a pivotal role in integrating European airspace, building our services around traffic flows not national borders.

What makes us unique


This is our top priority! Our safety management system and robust safety culture contribute to an excellent safety record.


Our multinational approach ensures that civil and military air traffic is managed as efficiently as possible irrespective of national boundaries.


We aim to deliver the highest possible level of performance through safety, punctuality, cost-effectiveness and environmental responsibility.


We record the highest levels in controller productivity and sector throughput in the core of Europe.


We are committed to developing innovative and proactive solutions to address the structural limitations of our congested airspace.

Customer focus

Our customer-oriented approach allows us to offer independent, transparent and flexible responses to our customers’ operational challenges.


Our MUAC ATM Knowledge Centre (MAKC) relies on close to 50 years of experience in efficiently managing air traffic across borders and guarantees a 25% improvement in ATM service delivery performance.

Unique customer services

MUAC has launched its Customer initiative with the aim to address trajectory inefficiency by proposing optimal flight plan opportunities to aircraft operators. In addition, MUAC now also hosts the ATM Portal, a special platform that gives all users the ability to collaborate, to share data and information, and to act on a range of cost-saving and environmental opportunities.

Join our ATS B2 ADS-C operations

ADS-C (ATS B2) is a datalink-based technology which obtains different types of information directly from the aircraft’s flight management system, without pilot interaction. It enables aircraft to automatically downlink the aircraft’s intended trajectory to the MUAC system, which is then displayed on controllers’ screens. With ADS-C, we can offer aircraft operators enhanced air navigation services and ensure safer, greener and more efficient operations.

The Tactical Capacity Manager on MUAC’s flow management position is the (pre)-tactical focal point for any aircraft operator operations control centre in regard to any flight through MUAC’s area of responsibility.

The MUAC Tactical Capacity Manager on duty is on-call to assist you in the pre-tactical and tactical phases. If you are an aircraft operator and require any urgent assistance, please contact our flow management position Tactical Capacity Manager at any time using the dedicated aircraft operators hotline.

Our team will be happy to provide aircraft operators with any tactical support (on the day of operation) or pre-tactical planning support on D-1+ ( the day before operations or beyond) relating to your flight(s).

We are able to advise you on the most favourable routeings and re-route possibilities for your flight if required tactically. We can also provide updates to you on the latest status of pre-tactical ATFM regulations, sector configurations, forecasts or slot and other operational issues.
