Abstract : The objective of this report was to investigate and formulate techniques for predicting the development cost and development time of automatic flight control systems in aerodynamically supported vehiclesboth manned and unmanned. An empirical approach is taken, using relevant historical data on 25 automatic flight control systems. The predictive methodology is formulated using two types of statistical estimation models. The resultant predictive techniques are expressed as simple algebraic equations that can be evaluated to obtain cost and time estimates for a proposed flight control system. The principal elements that are necessary to evaluate the prediction equations are a group of parameters generally defined prior to, or early in, an R and D program. Examples of these parameters are gross functional and design complexity of the automatic flight control system; performance and airframe characteristics of the vehicle; and scope and calendar date of the development program.
