foreign object damage การใช้

The high-mounted engines greatly reduce the risk of foreign object damage.
Vertical takeoffs and landings are riskier because of threats such as foreign object damage.
This avoids foreign object damage ( FOD ) when operating from dirty runways or dirt airfields.
Also, as their engine components are more robust they are less liable to foreign object damage than axial-flow compressor engines.
The second advantage of the tail-mounted engines was the reduction in foreign object damage from ingested debris from runways and aprons.
