This is an attempt to develop a computer program for analysing the flight dynamics to meet the need in the analysis of stability and control for a fixed wing aircraft. The purpose of this project is to develop a program for the use of students, lecturers and those who are into the designing oa an aircraft. By using this program, a lot of time can be saved because this program can reduce complex and difficult manual calculation and produce more accurate result. Generally, the function of this program is to analyse the longitudinal together with the lateral stability and control for an aircraft. beside this, it can alaso analyse the flying and handling qualities of an aircraft. the result is than presenta=ed in a proper way. The aspect of user friendly is emphasised in this program. This project is to develop a computer program that is easy to use.
