A study was conducted to determine function splitting modes for flight simulation which reduce computation time of function generation without deterioration of simulation quality. Analytical and experimental methods were developed for selecting and evaluating split function modes. Split function modes were tested on UDOFTT Universal Digital Operation Flight Trainer Tool using a program written during the study. The Split Function Evaluation Program provides a means of comparing flight simulation using a function splitting mode with a complete simulation in which all functions are computed during each cycle. Results of the study indicate that, for the short term longitudinal response of the aircraft simulated, the function generation interval can be increased to 1.5 seconds without significant deterioration of simulation quality except for functions comprising the critical coefficient. If functions comprising the critical coefficient are updated less frequently than .5 seconds, simulation quality may deteriorate. Author
