Device for controlling a system for monitoring the environment of an aircraft, in particular of a transport aircraft

A control device for controlling controllable functions relating to the monitoring of the environment of an aircraft, in particular of a transport aircraft, said control device (1) comprising a first control system (4) of a first type, comprising a plurality of control elements (A1 to A8) which are capable of being actuated by an operator, so as to control all said controllable functions (F1 to F8), which device furthermore comprises at least one second control system (5) of a second type different from said first type, which comprises a plurality of control elements (B1 to B6) which are capable of being actuated by an operator, so as to control at least some (F1 to F6) of said controllable functions (F1 to F8), and wherein said first and second control systems (4, 5) are in interaction so that an actuation of at least one of the control elements of one of said control systems (4, 5), so as to control one of said functions (F1 to F8) such as to bring it into a controlled state, automatically brings about an action, as the case may be on at least one control element of the other control system (5, 4) which is also intended to control this function, in such a way as to bring this control element into a control state which is representative of said controlled state of said function (F1 to F8).
