Abstract: A method for ensuring the safety of an aircraft flying horizontally at low speed includes determining a lower speed threshold for the aircraft, measuring the actual speed of the aircraft and comparing the actual speed with the threshold. When the actual speed reaches the threshold in the decreasing direction, the diving command of the aircraft is limited to a load factor (fg) greater than 0g. According to the invention: a lower speed threshold is determined for the aircraft; the actual speed of the said aircraft is measured; and the said actual speed is compared with the said threshold and, when the said actual speed reaches the said threshold in the decreasing direction, the diving command of the said aircraft is limited to a load factor (fg) greater than 0 g.

Abstract: A method and device for controlling the attitude of an aircraft may employ spoilers that are arranged on the wings of the aircraft and whose respective angular positions can be adjusted by controllable actuators. A command attitude determining section determines a command attitude of the aircraft corresponding to an attitude that the aircraft must achieve. A command position calculator calculates command positions of the spoilers, corresponding to particular angular positions of the spoilers, making it possible to bring the aircraft to the command attitude. A control instruction calculator calculates control instructions for the controllable actuators, making it possible to bring the spoilers into the command positions, and applies the control instructions to the spoiler actuators.
