LADR contributors will be those organizations: who have ADT solutions that have been approved for use by a State; are able to provide data to the LADR in accordance with the requirements defined by the LADR administrator; and have been properly accredited by ICAO. Potential LADR contributors will be designated as developmental submitters until they can demonstrate that appropriate quality systems can verify the accuracy and integrity of the provided data. LADR contributors should have policies and procedures to ensure that the data they submit is received and processed by the LADR. These include appropriate actions when notification of a ârejectedâ, âincompleteâ or âduplicateâ message is received from the LADR. The policies and procedures should also include a periodic verification that the submitted information is being processed correctly by the LADR.
