Data Quality

The need for high quality aeronautical information has never been greater.

Whereas traditional means of navigation relied on ground-based navigation aids to determine position, the move towards Global Navigation Satellite Systems such as Global Positioning System (GPS), Ground-Based Augmentation Systems (GBAS) and Satellite-Based Augmentation Systems (SBAS) has allowed advances in air navigation such as Area Navigation (RNAV) and Reduced Vertical Separation Minimum (RVSM), effectively increasing airspace capacity. Such advances rely on the data used being highly accurate. Further improvements in future navigation are foreseen which again are reliant upon data with high integrity.

In order for aircraft to safely navigate using the new methods, the data must be surveyed or derived (through procedure design for example) with high levels of quality and accuracy. Furthermore, the data must retain these levels throughout the data chain from the point of origination to the point of use. In essence, the integrity of the data must be maintained.

Key Benefits

• Meet the obligation of the ICAO:

The main requirements for the assurance of data integrity are captured within the ICAO Annexes to the Chicago Convention. These documents lay down the requirements which must be met to allow for the safe execution of flight.

• Improve efficiency and safety:

By ensuring aircraft are operating with high-integrity information, the pilot will be able to rely upon the information they have relating to, for example, infrastructure, leaving them free to concentrate on flying the aircraft and maintaining situational awareness.

• Increase capacity and throughput:

If the data in use is reliable and consistent, processes and techniques such as Collaborative Decision Making (CDM) may be adopted which, in turn, may lead to an increase in capacity.

Capabilities

• Standards and Guidance

Through initiatives of the European Commission and EUROCONTROL, a substantial body of new standards and associated guidance material relating to data integrity has been  developed. Mileridge can help you implement processes within your organisation to comply with this material.

• Systems Specification

In order to protect the integrity of information, States must look to minimise the manual entry and processing of data, this requires the introduction of new or modified systems. The specification of what changes are needed to an existing system or the functionality required by a new system must ensure that the integrity of information is assured. Mileridge is available to work with you in specifying these systems and in  validating that the systems delivered meet these requirements.

• Support Tool Development

The use of tools to process and / or validate data may be required by your organisation and, in the past, many such systems were "home grown". However, new regulations are making the creation of such tools more complex as the validation and verification of such tools and the processes employed in their development meet exacting standards. Mileridge offers a software capability which is available to your organisation. Our development staff work to an ESARR 6 compliant process to ensure that development is performed within a controlled environment.

• Support to ADQ Implementation

Mileridge can support your organisation in its assessment and implementation against the European Commissions Aeronautical Data Quality regulation. See our ADQ service for more information.
