Abstract:
1. A method for controlling control parameters of an air vehicle having a propulsion system and a plurality of control surfaces configured to allow pitch and roll control of the vehicle, the operation of the propulsion system and the positions of the control surfaces being controlled by means of control signals which are generated from data relating to the conditions of the vehicle and from control parameters comprising a parameter V indicating speed, a parameter R indicating turn characteristics of the vehicle in a horizontal plane, and a parameter γ indicating a path angle of a path which the vehicle must follow in a vertical plane; the method comprising the step of receiving input control parameters including an input parameter Vi indicating said speed, an input parameter Ri indicating said turn characteristics, and an input parameter γi indicating said path angle; characterized in that the method further comprises the steps of: a) V b) it allows setting the value of γ at a certain value which deviates as little as possible from the value of γi while at the same time meets the condition c) and such that it allows setting the value of R at an optimal value which deviates as little as possible from the value of Ri while at the same time meets the condition
