Means for avionics manufacturers to define the aeronautical data quality requirements

The paper studies the means with which the avionics manufacturers define the aeronautical data quality requirements. All participants in an aeronautical data chain must ensure that data quality requirements are correctly established for the data´s intended usage. The paper discusses how avionics manufacturers define required assurance level, accuracy, resolution, format and other characters for the aeronautical data that would be used in the avionics, so that the appropriate airworthiness regulation could be met.
