6. A web based system since 1998

7. 2010 ICARD global
27 August 2010 : full transfer from Eurocontrol to ICAO HQ
Now available in all ICAO Regions
The main ICARD menu gives information on the different services and database that Eurocontrol is providing to ICAO and for the aviation community

8. ICARD for public users ICARD direct access :
ICARD menu for public users

9. ICARD access for route planners
Access to ICARD is open to anyone for information
Guidelines for registration are provided on the same page
To note:
The future ICARD authorised user will initially register on the eurocontrol « onesky on-line »
ATS route planners are nominated by their Administration
Names of the designated route planners are communicated to the ICAO Regional Office accredited to them
After coordination between State/ICAO/Eurocontrol, access as icard authorised user will be granted
Route planners need prior registration

11. ICARD- Authorised user menu
Find Allocated and available 5LNC
verify the existence of a code in the ICARD database
Identify the state using the code or indicate its availability in a specific region.
To note:
The information covers all ICAO regions & transfer of codes is possible
ICARD contains all codes created in the 1960s but also a certain amount of codes which were not coordinated with ICAO – these are flagged as « non-icao » codes
Find 5LNC in Reserve List :
enable the authorised user to search for a new 5LNC and post a request for allocation
Find Allocated 5LNC :
find an information (allocation, geographical coordinates..)
amendment can be requested by the coordinating country (update, deletion)
4. Check my request:
The requests found in this menu are still pending – not yet approved by the ICAO data manager
the authorised user can make all modification or withdraw the requests which are still pending for confirmation
5. Requests by block :
Not recommended – will be withdrawn
6. Downloads
ICARD can generate
List of codes by country
List by name of codes
List of duplicates per country
List of duplicateds per code
7. List ICARD Contacts + List Country code indicators
Provide information on counterparts in other states or regions
List the ITU, ISO2, ISO3 country codes
8. Change password

12. Search for existing code
Searching the existence or the details of a 5LNC typing the code name
Wil immediately give the information of the state user and the 5LNC details as initially registered in the database

13. Search 5LNC with specific pattern
From a « search criteria »,
the authorised user can obtain a selection of codes with specific patterns, replacing letters with asterisks
To note :
the results will show a global information : available codes belonging to the region of registry will be underlined
codes underlined are active codes – available for allocation

14. Search sound-like 5LNC

15. Random search from given coord

16. Status of 5LNCs Codes for 5LNCs: blue codes are available
Underlined 5LNCs are active and available for your region
the authorised user selects and proceeds with the request
If not active (not underlined) = available but belongs to another region
Contact your data manager who will coordinate with the other ICAO Region and check whether transfer is possible
orange codes are pending for approval
red codes are already allocated

17. Posting a request

18. Sound-like proximity is mandatory
500NM is the radius currently determined as safe for a sounding like proximity
Checking sound like proximity is the responsibility of the route planner
The route plannerwill check the adequacy of the results obtained with the « list » function
The data manager will refuse requests that are not safety checked and confirmed.
From given coordinates, the « map » option will show the future code position and give a visual information of other existing codes in the required area
To note :
All options in the first menu « find allocated and available 5LNC » are also available to public users
to facilitate « in-house » coordination for future planification
to simplify correspondence between data managers and authorised user

19. Sound like check with list view

20. Proximity check with MAP view

21. Reminding Safety issues
Warnings are prompted to draw the authorised user’s attention on the necessity to modify the request.
An automatic prompt will inform the authorised user of the necessity to check proximity and confirm that action was done
Also when other similar codes are found within a close proximity, a warning will also be prompted.

22. Check my request Possible modifications for pending requests
At this stage, requests are still pending and can be modified or deleted by the authorised user

23. On-line Downloads

24. Next steps to ICARD global
5LNC lists comparison ICARD/AIPs
Clearing duplicates issues
at regional level
at global level
Our next challenge :
Develop a route designators system
