Abstract:
An apparatus for operating a controlled member (2) on a rotary-wing aircraft, said apparatus (1) comprising:at least one control (3) intended to be subject to the action of a pilot of said rotary-wing aircraft and capable of moving a linkage (4); means (5) connected to said linkage (4) for operating said controlled member (2) as a function of movement of said linkage (4); a first control device of a first type, said first control device comprising a ram (7) incorporated into the linkage (4) which is capable of influencing the movement of said linkage (4) as a function of control commands received; a second control device of a second type different than said first type, said second control device comprising a trim means (13) capable of acting on the control (3) and on the linkage (4) as a function of control commands received; a computer (9) determining said control commands which are transmitted to said ram (7) and to said trim means (13); and at least one sensor (10) which is capable of measuring the values of a parameter that represents an action exerted by a pilot of the rotary-wing aircraft on said control (3), wherein said computer (9) uses the values measured by said sensor (10) to determine said control commands to create control objectives, wherein the parameter measured by said sensor (10) is relative movement of said control (3) with respect to the position of the trim means (13).
