According to the literature, the more common possibility for a safety hazard or runway incursion to exist occurs when the exact location of an aircraft or vehicle on the airport surface is unknown or is contrary to an ATCT instruction; when either 14 controllers, pilots, or vehicle operators forget about a critical safety activity; or when proper procedures are not otherwise followed by controllers, pilots, or ground operators.
