ABSTRACT

The aviation software is developed by dividing the object code part and the parameter part into files. This is because various parameters need to be corrected for optimized flight control, so it is possible to correct only by modifying the parameter file without changing the configuration of the object code. As a result, if the changed parameter is within the valid range proved by the test for the code, the test cost can be reduced because the test for the code verification is unnecessary. These parameters are referred to as Parameter Data Items(PDI) in DO-178C, the standard for aviation software conformance. The conversion of this PDI into a binary file is called PDIF. In this paper, We design and implement a PDIF converter that generates an Excel sheet gain set with various flight scenarios for flight control law data and converts it into a PDIF set. The implemented PDIF converter can perform flight test without changing its configuration when a test is applied to the dynamic environment of Hardware In the Loop Simulation(HILS) for flight safety. The use of the Converter improves test convenience and saves test time as it enables continuous testing of various flight scenarios through PDIF set without interruption compared to the conventional sequential test for each single flight scenario. In addition, the (.dat) file can apply to other types of OFP and reduce the impact of OFP modification.
