SAGEM Patroller Flight Control System ◄ back to Flight Control Systems SAGEM has a  20 year long operational experience with automatic Flight Control Systems for its drones in various sizes. The Patroller-FCS is a further development of the battle proven system for the Sperwer UAV drone. All electronic hardware units of the FCS have a triplex redundancy for safety reasons. The FCS provides automatic take-off and landing for the Patroller aircraft (ATOL). The switch from manned mode to unmanned UAV mode (or vice versa) is immediate and needs no modification to aircraft or electronics. The Patroller operational over South France for wildfire detection and fire fighting management is flown in automatic UAV mode with a safety-pilot on board.
