In air traffic radio communication, call signs (aircraft flight identifiers) and other abbreviations can sound confusingly similar and can lead to potentially hazardous situations and accidents. EUROCONTROL asked Namahn to design an HMI prototype for a tool based on best practices and to be used by all air traffic stakeholders in the area of operations.

Individual airlines had introduced some automatic functionality with the help of database applications. However, these first approaches towards an automated solution led to repetitive work and were applied only locally.A database used for conflict detection at an Aircraft Operator

This model defines how users responsible for detecting and resolving similarities in a given flight plan will perceive the application, its content and behaviour inside the workflow.An excerpt from the mental modelfor call sign similarity detection using the CSS tool

The final HTML prototype allowed basic navigation and interactions.Our HMI prototype was able to hide the complexity of the tools underlying algorithms without loosing any functionality or efficiency.Sequence of screens of the final HTML prototypeof the CSS tool

We created a minimal but pertinent engineering specification to communicate all design concepts to the future developers in a concise and practical format.Sample from the engineering specification for the CSS tool HMI
- 14. Outcome Our design helped Eurocontrol to communicate its vision of how to deal with call sign similarity issues and get essential buy-in and commitment from the stakeholders on using the proposed CSS tool. It is scheduled to be made available via Eurocontrols NOP (network operations portal), a web-portal for providing operational information of the European airspace to all air traffic stakeholders.
