Abstract
An obstruction detection and warning system includes a plurality of edge light emitters, and a processing system. The edge light emitters are mounted on a structure that has a width and a height. Each edge light emitter is operable to emit a light beam at an angular rate, and that is encoded with data that indicates its position and its height. The processing system receives the light beam emitted from each edge light emitter and decodes the encoded data from the received light beam to determine the width and height of the structure, and to determine a distance from an aircraft to the structure. The processor also compares an active trajectory and current altitude of the aircraft to the width and height of the structure and the distance to the structure and, based on the comparison, generates and supplies situational cues to an operator of the aircraft.
