The Gate Park System consists of two guidance elements mounted at the gate in front of the aircraft, plus an operator's control switch The lateral guidance element consists of an aluminum housing and shade hood which support a pair of vertical, Light Emitting Diode (LED) light bars, one red and one green. The LED light bars are mounted fore and aft of each other on the same axis such that when the pilot is positioned directly in front of the LED bars, only green is visible. As deviation to left or right increases, the rear mounted (red) LED light bar is no longer shielded by the green LED light bar, making red visible. The red LED light bar would be visible to the left of the green LED light bar if, for instance, the aircraft drifted to the left of the taxi line approaching the gate. The forward motion guidance element consists of a polycarbonate, three (3) light, signal head, mounted horizontally and directly under the latéral guidance element. The indications are the red light signais "gâte unavailable” or "stop", the yellow light indicates "préparé to stop"; and the green light indicates "continue forward". Each light is equipped with a "visor type" sun shade. A ground operator is responsible for control of the forward motion guidance element by means of the operator control switch.
