J2 Classical, the latest plug in module released by J2 Aircraft, provides a fully integrated component of the J2 Universal Tool-Kit.
The module allows Linear Analyses and develops algorithms to establish modes of motion. This means that with J2 Freedom an aircraft can be initialised (trimmed) at any point in the flight envelope and with J2 Classical, the aircraft is then linearized about this point and a full state space system calculated along with eigenstructure, modes of motion, frequency damping etc. This analysis is not limited, though, to a single point but can be performed across the complete flight envelope in a single mouse click.

The use of J2 Classical with the substantial upgrade to J2 Visualize provides the user with a very powerful analytical and visualisation tool that saves time and greatly enhances the analytical capability of the engineer.
