Read the following report from NASA itself published 1988 entitled “Derivation and Definition of a Linear Aircraft Model” and…FREAK OUT!…
This report documents the derivation and definition of a linear aircraft model for a rigid aircraft of constant mass flying over a flat, non-rotating earth. The derivation makes no assumptions of reference trajectory or vehicle symmetry. The equations of the linear system are derived and evaluated along a general trajectory and include both the dynamics of aircrafts and the variables of observation.

This report derives and defines a set of linearized system matrices for a rigid aircraft of constant mass, flying in a stationary atmosphere over a flat, non-rotating earth.
