NOTE:
If no markings exist, local procedures must establish safe parking areas, etc.
CAUTION:
Results of FOD:
Foreign object debris may be sucked into aircraft engines causing damage leading
to engine failure. This is especially critical if it occurs in flight, particularly during
the take-off phase.
FOD can damage tires, the undercarriage, control systems and other parts of the
airframe which can lead to in-flight failures.
