The invention relates to instrument engineering and is used for easily controlling an inert object and an individual controllable parameter. Said display units can be in the form of an aircraft or car speed indicator, an air traffic controller display, a display showing the approach of space vehicles, information display devices of the desk of thermal and nuclear power plants, etc. According to the invention, a variable parameter signal incoming to the first channel of the display passes in a parallel chain via a differentiating unit, the differentiation result converted into an amplification unit is summed with a parameter value in an adding device and is transmitted to the second channel of the display. The result consists in that the position of an index in the second channel differs from the position of the parameter value index displayed in the first channel and outruns it during the common displacement along the scale at a value proportional to the displacement velocity thereof and displays a future value, and the distance between indexes (an angle, if they are pointers) shows the manner and the rate of the parameter variation. When the parameter is not changed, the predictable index coincides with the parameter index. |
