A control device for an air vehicle to control the compatibility of inputs entered by a pilot to operate the air vehicle said control device comprising: a body having a structure suitable to be placed on a control panel of the air vehicle, said air vehicle control panel comprising input tools, and wherein the body is adapted to be placed on the air vehicle control panel so as to prevent direct access of the pilot to the control panel input tools; several input tools arranged on the body and structured such that they at least partially match the input tools located the air vehicle control panel, and provide access to the control panel input tools, wherein each of the input tools on the body has the form of a key located on the control panel and/or of a control bar located on the control panel, at least one input tool drive unit associated with each input tool on the body and adapted to drive the tool on the body and to transmit an input to the associated input tool to the input tool on the air vehicle control panel CP), at least one memory unit located in the body for recording input data to be given to the air vehicle control panel according to predetermined conditions, at least one processor unit located in the body in communication with the input tool located on the body, the input tool drive unit and the memory unit, said processor being adapted to: communicate with the memory unit when sensing an input by the pilot to the input tool located on the body check if said input given to input tool which is activated by the pilot is a valid input in accordance with the data stored in the memory unit in the present case, if it indicates that the input is a valid input at the end of check, to operate the input tool drive unit associated with the input tool located on the body for transmitting said input to the input tool of the air vehicle control panel matching the input tool activated by the pilot and if it indicates that the input is not a valid input at the end of check, not to operate the associated input tool drive unit to inhibit transmission of the pilot-activated input tool to the input tool on air vehicle control panel matching the pilot-activated input tool. a body having a structure suitable to be placed on a control panel of the air vehicle, said air vehicle control panel comprising input tools, and wherein the body is adapted to be placed on the air vehicle control panel so as to prevent direct access of the pilot to the control panel input tools;
