Data Chain is a conceptual representation of the path that a set or element of aeronautical data takes from its origination up to end-use.There are classical databases such as navigation or terrain database and configuration files for modularity and portability purposes.These databases can be used to activate or deactivate software items, adapt the software computation to the aircraft configuration, or provide computation data.The RTCA DO-200B establishes three Data Process Assurance Level (DPAL) as the level of rigor, representing the amount of verification and validation tasks performed, during data processing to assure data quality.This paper presents four different and complementary validation techniques to ensure correctness for Aeronautical Databases.This work aims to cover the existing gap in the available standards, presenting and exemplifying some proposed techniques.It also presents some techniques and provides different comparisons and specific intentions.At the end, some relevant needs of qualified tools are discussed to ensure that the use of techniques can be automated, and credits can be sought using tools.
