Stability is the most important factor of a certain aircraft model, especially fighter ones due to its strong effect on the
ability to control and maneuver. Therefore, stability research is crucial in developing and validating flight simulator. In
the scope of this work, the longitudinal stability of Flanker-C-Like model was numerically assessed based on MIL-F-
8785C standard to confirm that its longitudinal behaviors are similar between the numerical model and real aircraft.
Specifically, Computational Fluid Dynamics (CFD) method was utilized to generate the aero-lookup table in the
aerodynamic model. This is the reason why, the flight dynamics model was developed to describe the six Degrees of
Freedom (DOF) motion based on the forces and moments generating on the aircraft. The aero-lookup table contains
static and dynamic coefficients calculated by Ansys Fluent and Athena Vortex Lattice respectively. The flight dynamics
model continuously calculated the states of aircraft by solving a system of differential
