The Center for Aerospace Research, working on the leading edge of the next generation of unmanned aircraft, carries out an extensive activity of flight testing with the objective of studying new configurations and systems to fulfil missions in the most efficient way. Since the acquisition of several projects by collaborators such as Boeing, Bombardier and the Canadian Department of Defence, the number of flight tests to be performed has increased substantially, requiring a radical change in the data handling method used to analyse the numerous log files generated. The project developed in this thesis proposes to solve this issue with the creation of a customized flight data post processor software, capable of managing all the data produced from the flight tests.
