Abstract:
Windshear indicator system comprised of a plurality of individual windshear detection and indication devices (10) disposed to one side of and parallel to the landing approach and takeoff areas of an airport runway. Each device (10) has a wind velocity sensor (24) and a wind direction indicator (22). Wind speed information is visually displayed in an array of vertical lights (30-40) of one color. A circular pattern of second colored lights (50-64) is provided so that the upper half of the pattern shows head winds and the lower half indicates or displays tailwinds to warn of a windshear condition. A green "go" light (74) flashes with the upper half of the circular lights (50-64). A red "no go" light (76) flashes with the lower half of the circular array of lights to warn of tailwinds and a windshear condition.
