Abstract

A system for detection of foreign objects on an aircraft travel surface and ascription of the foreign objects present on the aircraft travel surface to foreign object sources, the system including a foreign object detection subsystem operative to detect foreign objects on an aircraft travel surface, a potential foreign object source identifier subsystem operative to indicate the presence of potential foreign object sources at or near the aircraft travel surface and a foreign object to foreign object source correlator operative to receive inputs from the foreign object detection subsystem and from the foreign object source identifier subsystem indicating at least a time relationship between sensed presence of the potential foreign object sources on the aircraft travel surface and detection of the foreign objects and to provide an ascription output indicating the origin of at least some of the foreign objects detected by the foreign object detection subsystem.
