Section 3. Safety Precautions
The CFA user must:
a. Ensure that the

a. The service area
office must be satisfied that adequate safety
precautions are in place for each CFA. Specific
precautionary measures established to protect
nonparticipating aircraft and persons and
property on the surface will depend on various
factors such as the type of activity, terrain,
CFA dimensions, etc. The following measures are
