8.  National Security Areas

NSAs consist 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 provide a greater
level of security and safety, flight in NSAs

may be temporarily prohibited by regulation under the provisions of 14
CFR Section 99.7. Regulatory

prohibitions will be issued by System Operations Security
and disseminated via NOTAM. Inquiries about NSAs

should be directed to System Operations Security.

9.  Obtaining Special Use Airspace Status

a.

Pilots can request the status of SUA by contacting the using or
controlling agency. The frequency for the

controlling agency is tabulated in the margins of the applicable IFR
and VFR charts.

b.

An airspace NOTAM will be issued for SUA when the SUA airspace
(permanent and/or temporary)

requires a NOTAM for activation. Pilots should check ARTCC NOTAMs for
airspace activation.

c.  Special Use Airspace Information Service (SUAIS) (Alaska Only).

The SUAIS is a 24

-

hour service

operated by the military that provides civilian pilots, flying VFR,
with information regarding military flight

operations in certain MOAs and restricted airspace within central
Alaska. The service provides "near real time"

information on military flight activity in the interior Alaska MOA and
Restricted Area complex. SUAIS also

provides information on artillery firing, known helicopter operations,
and unmanned aerial vehicle operations.

Pilots flying VFR are encouraged to use SUAIS. See the Alaska Chart
Supplement for hours of operation, phone

numbers, and radio frequencies.

d.

Special use airspace scheduling data for preflight planning is
available via the FAA SUA website.
