The tool for developing airborne software requires the same level of safety as airborne software because the tool whose output is part of the airborne software and thus could insert an error into the airborne software. This paper describes how to ensure the reliability of the tool output that becomes a part of the airborne software by validating of the input and output files of the tool when generating the ARINC 661 standard UA definition file and the CDS configuration file through the A661UAGEN tool of Hanwha Systems. We present the method to validate XML data structure and contents with an XML schema definition, which is an input of the A661UAGEN tool. And the method to validate the output binary data by using mask data for the corresponding data structure and valid value, which is the output of the A661UAGEN tool, was presented. As such, validation of the input and output of the tool improves the reliability of binary DFs and CDs integrated into the airborne software, allowing airborne software developers to utilize the tool to ensure safety in developing the OFP.

DO-330 Software Tool Qualification Considerations is a guideline for development of tools used to develop/verify software and hardware installed on aircraft. And among several processes, the verification process is very crucial as it occupies a large proportion for DO-330. Especially, in order to qualify tool with high safety level, test objectives must be performed with independence, accordingly, more time, cost, and manpower are required than other objectives. In addition, even if the test cases or test procedures are well defined, the higher the complexity of the test the higher probability of human error occurs. In this paper, we propose Script-based Test Automation Agent software structure for efficient DO-330 verification process of A661UAGEN tool developed by Hanwha Systems. Compared to the test performed manually by the test engineer, testing time of the Script-based Test Automation Agent is reduced by 87.5% and testing productivity is increased by 43.75%.

The present study aims to demonstrate that it is possible to objectively evaluate the competency (referred to as graduate attributes or program outcomes) of graduates of engineering education programs. To strengthen the link between engineering education accreditation and the qualification/certification system of engineering professionals, referred to as K-Engineering Professional (K-EP), individually assuring the quality of accredited graduates using multiple-choice test as main assessment tool is proposed. Test questions related to the basic vocational skills of NCS are developed for seven of the 10 program outcomes of the ABEEK KEC2015. The three program outcomes, PO1, PO3, and PO5, which need to fully accommodate the characteristics of each disciplinary field, are excluded. A pilot test involving graduates of eight accredited programs is conducted. Applying on Rasch model based on Item Response Theory (IRT), the item difficulty, fit and discrimination of multiple choice test are demonstrated. The pilot study strongly suggests that individual competency evaluation is possible at a certain level for seven program outcomes tested. For PO1, PO3, and PO5, however, questions that address the characteristics of each disciplinary field need to be devised. If a suitable pool of questions is built, it can be used as a program outcomes assessment tool by the accredited programs.
