This paper deals with the experiences in reengineering an existing system and developing an object-oriented design for the current system. The subsystem under study is the terrain following algorithm (TFA) or the vertical steering subsystem, a component of the guidance system of the operational flight program (OFP). The OFF is a major subsystem of the integrated test bed (ITB) facility used to support the development, test, and evaluation of advanced avionics systems in the avionics directorate at Wright-Patterson air force base. The techniques used in this reengineering process included structure charts, object-oriented structured design (OOSD) notation, and visibility diagrams for Ada packages. For developing an object-oriented design, the object modeling technique (OMT) by Rumbaugh et al. was used. Some of the CASE tools used for reengineering were Software Through Pictures, Rational Rose, and OMTool.
