Air-to-Air Combat Flight Dynamics Governed by Flat Earth Model

A STUDY INTO ADVANCED GUIDANCE LAWS USING COMPUTATIONAL METHODS by Daniel Perh December 2011, NAVAL POSTGRADUATE SCHOOL,

“For this simulation, flat earth approximations are used, as the ranges involved in air-to-air combat are relatively short as compared to tactical ballistic missiles, and a point mass model will be assumed for the flight dynamics. The following vector equations fully describe the motion dynamics of a free body in space… The equations used in (2.1) are intended for flat earth approximations. Hence they do not include terms that transform the NED frame to an earth centered inertial (ECI) frame. Those terms would be needed for simulations that require modeling of the missile flight path over a spherical, rotating earth, such as simulations of ballistic missile trajectories.”
