FM Program: FAA-sponsored Software Work

Under sponsorship of the Federal Aviation Adminstration (FAA) link to external site, we have been conducting research into various aspects of software specification, development, verification, and validation for several years. The specific current and recent projects are as follows:

  • Development of a tutorial on Modified Condition/Decision Coverage (MC/DC). MC/DC is a DO-178B objective for software structural coverage required for Level A software. We have produced a tutorial to explain the purpose of MC/DC and provide a practical approach for meeting the MC/DC objective and determining whether that objective has been met. This work was done with Dan Veerhusen (Rockwell Collins, Inc.), John Chilenski (Boeing Company), and Leanna Rierson (FAA).
  • Investigation of issues in the use of object-oriented techniques in safety-critical systems. We are working with John Chilenski of the Boeing Company to provide input to the FAA on the use of object-oriented technology in aviation systems. In particular, we are investigating issues related to structural coverage and issues related to software tools used in development and verification of object-oriented software.
  • Participation in the activities of the joint RTCA/EUROCAE SC 190/WG 52 link to external site, which was formed in 1996 to clarify issues regarding the document DO-178B/ED-12B, "Software Considerations in Airborne Systems and Equipement Certification".
  • Streamlining Software Aspects of Certification
