Foreign object debris (FOD) at airports can cause damage that costs airlines, airports, and airport tenants millions of dollars every year.
FOD includes any object found in an inappropriate location that - as a result of being in that location - can damage equipment or injure aircraft or airport personnel. The resulting damage has been estimated to cost the aerospace industry $4 billion a year. Airports, airlines, and airport tenants can reduce both this cost and the risk to safe flight that can result, by taking steps to prevent airport FOD.
