A study of the NAS Enroute computer program was made to determine the efficiency of the current code and to suggest ways of improving the program. The problem was divided into several areas to study improvements in the monitor, the data base, the mathematical algorithms, the program structure, and local code optimization. The results indicated that the program can be significantly improved. In another part of the study a typical program segment was selected, redesigned and recoded. The redesigned program was smaller, simpler, faster and more accurate. The recommendation of the study is that the NAS program be completely redeveloped. If this is not done, the study recommends improving the program by redeveloping large program segments and redesigning portions of the data base. Lesser improvements can be made by structural changes, local code optimization, and documentation improvements.
