MIL-HDBK-1012/1
c) Red/black criteria and methodology shall be as delineated in
Chapter 12 of NAVELEX 0101,102, and MIL-HDBK-419.
8.7.3.4
Shielding
a) Where there is a great deal of DC signaling, such as in
computer, CIC-mockup, and simulation areas, consider provisions for coaxial
cable to prevent signal interaction.
b) Shielded enclosures or rooms lined with foil or mesh shall be
used where low-noise and/or low-level devices must be aligned or demonstrated.
8.7.3.5  Electromagnetic Compatibility (EMC). Since the training equipment
must be capable of operation in various stages of disassembly, the shore
training facility must compensate for electromagnetic-field retention
deficiencies in the training equipment.
a)  Effective grounding systems for EMC shall be developed as
required for the individual case.
b) The training-equipment station ground shall be isolated from
all other ground systems in the facility,
c)  Each classroom shall have a separate, AWG 4/0 (or larger)
insulated ground feeder.
d) Each piece of equipment, sub-assembly, test fixture, and test
equipment shall be connected to the station ground feeder.  The AC green-wire
protective ground shall not be used as a substitute.
e) Transmitters, exciters, and power amplifiers shall terminate in
well-shielded, impedance-matched dummy loads.
f) The transmission line to each dummy load shall be well shielded
and as short as possible.

Naval Air Station Control Towers.  The primary function of the
control tower is to centralize control over aircraft activities, both on the
ground and in the air, and to promote safe and orderly movement of air
traffic. The Visual Flight Rules (VFR) room is housed at the most
advantageous position and elevation with respect to the airfields to provide
complete visual control.  The tower receives support from the Instrument
Flight Rules (IFR) room, which provides radar contact at distances beyond
visual range and under other than optimal visual conditions.  The tower
includes space on various floors for electronic Air Traffic Control (ATC)
equipment, in addition to facilities within the tower cab for control and
operation of the equipment.  The control tower structure also provides space
for passageways for interconnecting cables. For further information, refer to
NAVELEX 0101,107.
Architectural and Structural.  In addition to the general
8.8.1
requirements of Section 3, the control tower shall conform to the following:
