The proven leader in ATM Voice Communications

Providing reliable, high-quality voice communications is one of the pillars of successful Air Traffic Management (ATM). With more than 200,000 flights a day, communication between ATC and pilots is more crucial than ever to guarantee successful aircraft movements both on the ground and in the air.

Good communication reduces the risk of accidents and is therefore a critical safety aspect in aviation. As with any safety aspect, the best practice is to rely on domain professionals to guarantee seamless communication. This is where Frequentis, market leader in ATC voice communications, comes in.

FREQUENTIS to ensure greater airspace safety and capacity for EUROCONTROL MUAC fallback operations

  • Safety and airspace capacity will be enhanced at one of Europe’s busiest and most complex airspaces
  • The Fallback Controller Working Position (CWP) follows Single European Sky open data interface principles
  • Based on the Frequentis OneATM user interface framework ODS Open Platform, the CWP ensures resilient operations even at high traffic volumes

EUROCONTROL, MUAC, one of the Air Navigation Service Providers (ANSPs) of four EUROCONTROL member states – Belgium, Germany, Luxembourg, and the Netherlands, selected Frequentis to provide its CWP as part of the MUAC fallback automation system. To ensure a high airspace capacity during fallback operations, while maintaining safety levels, EUROCONTROL's primary CWP will be mirrored by the fallback system, enabling controller requirements to be met in a similar way.
