Abstract
This paper describes a new control system proposal for complex Autopilot subsystem to integrate in aircraft model. Permanent control, decision making, resolution of a problem that need a large number of parameters are all an imperative for modern aviation which exceed in certain cases human capacities that's why the recourse to automatic piloting. This technique invades a classical aeronautical field or innovative ones (drones). Current research work aims at studying ArduPilot autopilots type.
