A visual display system for use by aircraft flight personnel in displaying flight criteria comprises one or more visual display devices including one or more display screens and a manually operable control panel remotely connected thereto and to a power source. The control panel has an off-on power activation switch, a multi-position, multi-characteristic selector knob switch to select characteristics and cause their input to a display device, and one or more multi-position, multi-numeral selector switches for selection of numerical input to a display device. With multiple display units, a selector switch is included to determine which display device receives the input and a holding circuit to cause retention of the visual display in one of the display devices while input is passed to and displayed in another of the display devices. It can also include switches to control the number of zeroes associated with the numerical input and a dimmer switch.
