scope:

This document provides for the improved operational effectiveness of airborne navigation systems that use stored databases. It presents a collection of disciplines necessary to provide assurance that aeronautical information used by the aviation industry meets the high quality and integrity for safe flight. The information in the document has been compiled for the purpose of stating aeronautical information requirements of the aviation industry with emphasis on RNAV operations in RNP airspace. There is focus on the importance of quality aeronautical information and the fact that the evolution of computer navigation technology requires a greater dependency on the accuracy, reliability, integrity, and timely availability of navigation reference data than ever before. This is a joint RTCA/EUROCAE document.
