CADAS‑IMS fulfils all requirements of a modern user-friendly Aeronautical Information Management (AIM) system. The full range of NOTAM, OPMET, and Static Data Operations enables powerful briefing services setting new benchmarks in this area. The system can be easily expanded to manage further dynamic data types. The modern HMI with its self-explanatory, easy-to-handle graphical surface offers quick access to all features and allows convenient operation by means of practical functions and various system services. CADAS‑IMS terminals run in standard Web browsers using latest Web technology. Therefore, no local installation, set-up, and configuration procedures are required. High scalability and flexibility make CADAS‑IMS the ideal tool for installations ranging from small airports to nationwide solutions.

Not only does CADAS‑IMS strictly follow international standards and procedures. It has also been developed in accordance with the latest recommendations from ICAO and EUROCONTROL. Of course, current security standards have been applied, in order to meet the stringent requirements imposed on the ATM environment of today.

  EAD System Interface (ESI)
  AFTN/AMHS
  SOAP, WMS, WFS/WFS-T

The AIS Application provides services for NOTAM Officers, MET Officers, Airlines, and Tower Controllers. The system fully supports and integrates production, distribution, and management of dynamic data like NOTAM, OPMET, FPL, and RPL, as well as static data like electronic AIP and aeronautical charts.

NOTAM
The system provides all features of an International NOTAM Office (INO) and can be easily adapted to individual customer-specific workflows. Sophisticated checks and input wizards assist the user, thus offering a maximum of convenience and preventing the user from entering incorrect data. NOTAM checklist and summary production can be automated to help keeping the NOTAM database consistent.

OPMET
OPMET services include TAF, GAMET, SPECI, SIGMET, and METAR message forms, message retrieval, and OPMET database management. The possibility of including meteorological information in the CADAS‑IMS Pre-Flight Information Bulletins and embedding image data for briefing purposes from external sources provide the user with up-to-date information.

Briefing
The CADAS‑IMS briefing module supplies pilots with the latest and most accurate flight-relevant information and also covers all aspects of an internet-home-briefing solution. Following the standards of the EUROCONTROL AIS AHEAD program, it implements the‚ one stop shopping model by providing information and services of AIS, OPMET, and ARO. Users can file flight plans, create PIB-based flight data, and view and select AIPs and Charts.

Depending on the flight category, the system provides the following briefing types:
Area Bulletin, Aerodrome Bulletin, Route Bulletin, Narrow Route Bulletin.
The system's strong graphical capabilities, such as NOTAM and chart visualisation, combined with a sophisticated filter with appropriate selection criteria, help to quickly get a clear overview of current conditions. Various adapters, such as e‑mail and SMS, can be configured in order to provide update information on a previously issued bulletin.

FPL
A powerful built-in field wizard assists the user in creating messages. Online field checks guarantee the composition of valid messages so that no erroneous message will ever leave the system. Message operations are further facilitated by the possibility of storing draft messages, flight plans, and routes in databases for later use. FPLs and related messages are addressed automatically, which again reduces the possibility of errors. Special addressing features are provided if the system is operated within the IFPS zone.

RPL
Repetitive flight plan lists can be defined and maintained by means of a convenient RPL application. The CADAS‑IMS task scheduler processes all active RPLs and generates and submits the respective FPLs automatically.

FSP
Flight strips containing flight-relevant information for controllers can be printed as paper strips by means of the FSP application. The system supports inbound, outbound, and overflight categories.

EAD Interface
To round off the system's outstanding features, CADAS‑IMS acts as a data provider and consumer for the exchange of NOTAMs with the European AIS database (EAD).

AIP & Chart Integration
CADAS‑IMS interfaces and provides workflow integration with market-leading COTS AIP- and chart-production systems. CADAS‑IMS supports the standard ARINC and EUROCONTROL AIXM formats.

Database
CADAS‑IMS is based on a COTS Relational Database, either commercial (Oracle) or open source (PostgreSQL). The database is designed to handle

• international NavData ARINC 424 reference data set
• AIXM static data
• all kinds of ATS messages
• NOTAM/SNOWTAM/ASHTAM messages
• MET Data messages
• flight plans and related messages
• on-demand and scheduled PIBs.

User Interface

CADAS‑IMS can be integrated into existing environments in many ways because of its Service Oriented Architecture. The following list gives some examples for the versatility of CADAS‑IMS integration.

• Client/Server system in a secure LAN infrastructure. This is the recommended configuration for a NOTAM Office.
• Web Servers connected to the Internet with Briefing and Flight Planning Portal. The sophisticated user management allows administration of a large number of users. Therefore, this is the perfect solution for nation-wide self-briefing services and flight planning.
• Autonomous NOTAM/MET/AIP/Chart EAD-connected Database for Briefing Services provided through a system-to-system interface, e.g. SOAP. Easily fitting into airline system infrastructures, it satisfies the needs for up-to-date and high quality data.

Moreover, configurations can be combined in order to serve different purposes at a time. Of course, functional modules can be deployed on separate hardware in order to fulfil existing security requirements.

Technology
The system is based on a client/server architecture. It consists of COTS servers and COTS PCs. Both the servers and the databases are fully redundant, thus ensuring high system availability and data security. Any standard-compliant Web browser can connect to the server.

Roadmap
CADAS‑IMS is being enhanced to support digital NOTAMS (xNOTAM) and AIXM-5
