OOTiA -- Object Oriented Technology in Aviation

The OOTiA program was started in response to increased interest in industry in using object orientation in the development of aviation software. Within this program, NASA and FAA are collaborating with industry, military, and academia to identify and address safety and certification concerns associated with object orientation. As part of this program, NASA Langley is sponsoring workshops to identify issues and guidelines for the safe use of OO.

Study of Qualification Criteria for Software Verification Tools

The purpose of this FAA-sponsored project is to evaluate current regulatory criteria for qualifying software verification tools used for aviation software and to determine if additional or alternate criteria are needed to ensure suitability of structural coverage analysis tools for meeting regulatory requirements. The scope of this study is limited to structural coverage analysis tools, especially those tools that provide analysis of modified condition/decision coverage (MC/DC).

Modified Condition/Decision Coverage (MC/DC) Tutorial

In cooperation with Rockwell Collins Inc, the Boeing Company, and the FAA, we have produced tutorial on MC/DC that provides a practical approach to evaluating MC/DC on a Level A software project and assessing whether the MC/DC objective has been satisfied. 

GCS -- Guidance and Control Software Project

The GCS project was a case study involving the development of guidance and control software in compliance with the life cycle processes for Level A software defined in the DO-178B guidelines. The compliance data from the GCS project has been used extensively by the FAA for training. 

SSAC -- Streamlining Software Aspects of Certification

The FAA started the SSAC program to address concerns about excessive cost and time associated with software approval, in particular, software approval in compliance with DO-178B. As part of this program, Kelly led team of technical experts to attempt to determine whether the cost and time associated with certifying aircraft can be reduced without compromising safety. The team collected data about cost and schedule drivers through a number of industry workshops and an industry-wide survey.
