CADAS-ATS: Terminal System for Air Traffic Services

Terminal System for Air Traffic Services - CADAS-ATS

CADAS-ATS is an ATS terminal that provides messaging services and flight planning capabilities for aeronautical offices, airlines and pilots.

CADAS-ATS combines AFTN messaging services with the messaging capabilities of X.400/AMHS. It enables AFTN and AMHS to be operated side by side on a single terminal. The user agent supports both basic and extended ATS Message Handling Services as defined in ICAO DOC 9880, second edition. CADAS-ATS features flight planning functionalities, including the web-based pilot portal, which enables visual route planning, filing of flight plan proposals, and home briefing, and the active flight database (AFD), which enables operators to monitor the status of flights for which they are responsible.

Optional SOAP (Simple Object Access Protocol) and AMQP (Advanced Message Queuing Protocol) interfaces in accordance with ICAO Manual on SWIM Concept (Doc 10039) are available to provide a bridge for data exchange with future SWIM services.
