Q

National Security Area (NSA)

A

Areas consisting of airspace of
defined vertical and lateral dimensions established at locations
where there is a requirement for increased security and safety
of ground facilities. Pilots are requested to voluntarily avoid
flying through the depicted NSA. When it is necessary to

may be temporarily prohibited. Regulatory prohibitions are
disseminated via NOTAMs.
