Which statement is true about the two types of FOD?

• A. They are Manmade and Natural
• B. They are Airborne and Ground
• C. They are Visible and Hidden
• D. They are Internal and External

Answer: (A)

FOD is any foreign object or debris that could cause damage to an aircraft, and it is categorized by origin: manmade debris and natural debris. Manmade FOD comes from human activity during maintenance or operations—things like loose tools, caps, fasteners, or scraps left on the ramp or in work areas. Natural FOD comes from the environment and wildlife—birds, seeds, ice, leaves, or other natural debris that can be ingested or strike an aircraft. Recognizing this distinction helps crews apply targeted prevention: securing equipment and ensuring tools are accounted for to prevent manmade FOD, and addressing wildlife hazards and weather-related debris to minimize natural FOD. The other options describe where FOD is, whether it’s visible, or whether it’s inside or outside, rather than where it originates, so they don’t define the two types.
