Diapason Takes Off: A New Chapter for DSNA. Diapason, DSNA’s first Cloud-based business application, officially launched in July at the Paris and Marseille Area Control Centers (ACCs). This marks a major milestone in DSNA’s digital transformation, aligning with its 2030 strategic plan to modernize air traffic control systems.
By replacing paper-based workflows with a tablet-based platform, Diapason delivers real-time access to operational documentation and enables controllers to digitally report safety events—a significant step toward smarter, faster aviation operations.
Diapason’s Core Function: Streamlining Safety and Documentation
At its heart, Diapason simplifies the way controllers interact with operational data. Instead of relying on printed manuals and handwritten forms, controllers now use ergonomic tablets to access documentation and submit Reporting Forms instantly.
This shift improves efficiency, accuracy, and response time, especially during safety-critical events. It’s a user-friendly solution designed to meet the evolving needs of modern air traffic control.
Cloud Migration: A Strategic Advantage for DSNA
Moving Diapason to the Cloud unlocks a range of operational benefits:
- High availability and resilience, thanks to redundancy, backups, and real-time monitoring
- Automated deployments, reducing delays and manual effort
- Scalability to support future growth and data demands
- Centralized distribution, making updates seamless across control centers
These features ensure that DSNA’s systems remain robust, flexible, and ready for tomorrow’s challenges.
Teamwork Behind Diapason’s Success
The launch of Diapason was made possible by close collaboration between developers, operations teams, and Cloud specialists. This pilot project showcases how interdisciplinary teamwork can drive innovation and deliver real-world impact. It also sets a precedent for other business applications to follow, as DSNA (Direction des services de la Navigation aérienne) continues to build a modular and maintainable systems architecture.

What Diapason Means for You
For controllers, Diapason means faster access to critical information, simplified reporting, and greater operational clarity. For DSNA, it’s a strategic leap toward a more resilient and scalable infrastructure.
And for you—whether you’re in aviation tech, operations, or policy—it’s a signal that digital transformation is no longer optional, but essential.
Diapason provides air traffic controllers with digital access to operational documentation and allows them to submit safety event reports directly from tablets. It replaces slower paper-based processes with a more efficient, ergonomic solution.
Migrating Diapason to the Cloud improves system resilience, speeds up deployment, and allows centralized updates across control centers. It also supports scalability for future data needs and ensures high availability through real-time monitoring.
Controllers gain faster access to critical information, simplified reporting workflows, and a more intuitive interface. This helps improve safety, reduce delays, and streamline daily operations in en-route control centers.
