The USAF Digital DATCOM allows a user to model an aircraft in order to analyze the stability and control of aircraft at different angles of attack and flight regimes. The details of creating this model can be found in the USAF Digital DATCOM Volume I.
The process of creating a model in Digital DATCOM is somewhat tedious and how the components of the aircraft are put together can be a mystery. This program is useful in order to quickly check and debug the configuration and ensure the model is created correctly. Obviously, an inaccurate model can lead to inaccurate results from Digital DATCOM.
