Abstract

Disclosed is an aircraft collision avoidance system having remote triggering means, multicolored lamp display, audible alarm, and a stroboscopic light for providing adequate early warning to an aircraft tug operator and other surrounding individuals that a possible emergency situation may exist. The system comprises four assemblies: (1.) a portable unit; (2.) a tug unit; (3.) a station unit; and, (4.) one or more hand wand transmitters. The station unit comprises a strobe light mounted to a building or gate and is positioned so as to be visible by a tug operator and flightcrew. The tug unit comprises an audible alarm mounted within the tug vehicle which is audible to the tug operator when triggered and a highly visible strobe light. The portable unit comprises an audible alarm that sounds when triggered and a highly visible strobe light. The portable unit may be utilized in place of the tug unit or may be utilized in conjunction with the tug unit at other positions, depending on the degree of warning needed. Each watch person carries a hand wand transmitter which he manually activates in case of impending collision or other emergency. The hand wand transmitter generates a radio frequency signal that is detected by a receiving circuitry contained within the portable unit, the tug unit and the station unit, thereby activating the respective alarming systems of each unit to warn the tug operator and others that an emergency situation exists and that all movement should cease.
