Text 13 ead : Data Quality

One of the major objectives of the European AIS Database (EAD) is the improvement of the quality of data. Data quality will continue to increase as all parties use standardized rules and procedures, implement at system level, and ensure cross-border consistency. Additionally, the other quality improvement steps have been taken to ensure that errors, which where not detected during input, in the EAD are identified and rectified, thus enhancing the quality of the data contained in EAD.

In order to ensure the highest levels of quality of the whole EAD, the data contained within the EAD is reviewed in accordance with the Service Provider QMS. This does not only include the data processed by the EAD Service Provider but it also includes the data updated by the migrated Data Providers. Furthermore for each error, the severity will be determined according to a specific classification which is based upon the potential risk resulting from the corruption of data upon the use to which the item data is put as defined in ICAO Annex 15, item 3.2.8 and Appendix 7. In case of an original or Data Provider error, the relevant Data Provider and/or originating State are informed while all other errors are corrected by the EAD Service Provider.

Rigorous quality checking procedures have been put in place to ensure that the quality of the data within the whole EAD is of the highest level. The standardization of data input rules, together with data checking and rectification, are and will remain therefore on of the major focal points of everyone involved in the EAD to ensure, in time and relevant delivery of aeronautical information.

Questions:

1. Why will data quality continue to increase?

2. What is done in order to ensure the highest level of quality?

3. What is done in case of an original or Data Provider error?

Text 14 Transition from ais to aim

We are in the age of the Internet, satellite navigation and computer networks, yet our approach to aeronautical information distribution is still based on paper charts, paper documentation and telex-based text messages. Much of the data is entered more than once in different computers using a keyboard rather than by file transfer or database transactions.

The computer-base navigation systems, and area navigation (RNAV), required navigation performance (RNP) and air traffic management requirements, introduced a need for new corresponding AIS requirements for quality and timeliness of aeronautical information.

The role of present AIS would need to transform to an information management service, changing duties, responsibilities and scope to satisfy these new requirements and to cope with and manage the provision of information. The definition of a future high-level view as to the shape, nature and content of a strategy for the evolution from traditional product-centric AIS to the enlarged scope of data-centric aeronautical information management (AIM) began and ICAO took the lead at the global level with regard to the transition from AIS to AIM.

Questions:

1. What is our approach to aeronautical information distribution still based on?

2. What introduced a need for new corresponding AIS requirements for quality and timeliness of aeronautical information?

3. What would the role of present AIS need to transform to?
