Abstract
Airport landing indicator apparatus designed basically for remote airports and landing fields including means responsive to wind direction and a pair of runway locators, in the form of lighted directional arrows, located at opposing ends of a runway. Wind direction determines which of the arrows will be lit for maximum safety in landing. Each of the runway locators includes a multiplicity of high intensity lamps forming an outline of a first arrow and a multiplicity of low intensity lamps contained within the confines of the high intensity lamps forming a second arrow. All lamps of a particular runway locator may be turned on by radio control from an approaching aircraft. The high intensity lamps, necessary for long distance observation, are automatically turned off by means of a photoelectric cell actuated by landing lights of the approaching aircraft to prevent temporary blindness. The apparatus may also contain a lighted specific wind direction indicator and a wind velocity indicator.
