Abstract:
1. A system configured to convert an aircraft from a flight condition lying outside a permissible flight condition range to a flight condition lying within the permissible flight condition range, that is assigned to a sensor system and a control device of the aircraft, comprising: a control override module configured to take over or returning the control authority over the aircraft based on a control take-over signal and for feeding control set points if the control takeover signal is set; a maneuver selection module configured to provide and storing at least one conversion strategy with associated maneuver information and for selecting a conversion strategy depending on measured variables of the sensor system; a threshold value generator configured to calculate the flight range limit on the basis of measured variables of the sensor system; a decision module functionally connected to the threshold value generator and the sensor system and to receive from the value generator the calculated flight range limit and from the sensor system the measured variables, and to generate a control takeover signal based on a comparison of the flight range limit with the measured variables and to transmit it to the control override module, the command generator and the maneuver selection module; a command generator functionally connected, on the one hand, to the decision module and the maneuver selection module and, on the other hand, to the control override module and, when the control takeover signal is set, calculates the control set points based on the maneuver information and transmits them to the control override module.
