The control loading system must take in inputs from the simulator and pilot and provide outputs for the pilot and simulator. Inputs are application of force and aircraft states and outputs are flight control position and forces. An aircraft with reversible controls needs to have all of the complex components modeled within the control loading system. These include cables, rods, aero forces from the control surface, centering springs and trim actuators. As the control system gets more complicated they have to simulate effects such as bob-weights and feel units. Fly-by-wire systems are disconnected from the control surfaces and so do not need the complex features but add other functionality which is simulated. The high fidelity architecture has centralized control, individual analog signals to the control module, a brushless DC motor with low gear ratio and linkages to the pilot controls. The modular designs have localized control and digital reporting over a field bus to the central control module. The control loading systems are designed to allow situating the actuators closer to the pilot. This is necessary for mission training systems[1] that can be easily deployed and moved around the world.
