Abstract: Disclosed are a method and system for improving real-time determination of flight parameters of an aircraft during flight. A selection module selects and delivers measured values of input parameters to an estimation unit, and the estimation unit uses the input parameters to estimate at least two selected flight parameters. The input parameters are received by the estimation unit on the basis of identified flight mechanics equations associated with the selected flight parameters. The estimation unit includes an extended Kalman filter, which is configured to receive the values of the input parameters and to output joint estimations of the selected flight parameters based on the flight mechanics equations, during the flight of the aircraft.

Abstract: An aircraft device includes a rudder, a control unit that applies a deflection instruction to the rudder, a measuring section that measures a recovery characteristic of aircraft movement in response to the rudder deflection instruction, a recorder that records an applied deflection instruction and a corresponding recovery characteristic, and a servo-control that maintains the recovery characteristic. The control unit receives a recovery instruction for a recovery characteristic, which is identifiable for an aerodynamic effect, and generates the rudder deflection instruction induced by the recovery instruction.

Abstract: The inventive device (1) comprises at least one rudder (2A, 2B, 2n), a control unit (4) for applying a deflexion instruction to the rudder, means (6) for measuring recovery characteristic displaying the evolution of the aircraft movement in the response to said rudder deflexion instruction, means (7) for recording at least one applied deflexion instruction and a corresponding recovery characteristic, a servo-control means (13) for triggering the aircraft in such a way that the recovery characteristic is maintained, wherein the control unit (4) is provided with means (10) for receiving an recovery instruction which makes it possible to obtain a recovery characteristic which is identifiable for at least one aerodynamic effect and means (11) generating the rudder deflexion instruction induced by the recovery instruction.
