The standard control tower includes a control room (control cab), electronic
equipment rooms, an emergency communication systems, emergency generator
equipment, air conditioning equipment, and sanitary facilities. It is
normally a five-story structure, although control towers may contain as many
as ten stories to provide adequate visibility. A height of 43 feet (13.11 m)
from the ground to the floor of the control cab is the minimum acceptable
elevation. The standard air station control tower is usually an integral part
of the operations building. If the control tower is a separate unit, the
design should allow for future expansion of the operations building. The
ground floor area should be large enough to permit easy repair and maintenance
of the emergency generator. The electronic equipment room should be designed
to house the emergency communication equipment, voice recorders, the main
distribution frame, and other equipment. The use of FAA standardized designs
for control towers is recommended.
Mechanical. The requirements of Section 4 apply to the mechanical
design of control towers, except as follows. Consult the project BESEP for
a) Remote transmitters and receivers associated with towers
generally require air conditioning.
b) If remote buildings are associated with the towers, a central
alarm system should be provided for fire, equipment failure, and other out-of-
tolerance conditions, such as high temperature.
c) Special fire protection requirements may exist for remote
Power Requirements. The primary power source shall be used during
normal operating conditions. An automatic-start and switchover emergency
generator shall be located on the ground floor. Unless an automatic-start
generator is immediately available, battery-operated equipment is required.
a) Ceiling. Ceiling lights shall be recessed so as not to reflect
in the windows of the cab.
b) Console. Low-intensity directional lighting shielded from the
equipment operator's direct view shall be provided on top of consoles for
nighttime operation. The light shall be directed along the planes of the
console work surfaces with a minimum of window reflections.
c) Floor. Low-level lights shall be provided under consoles for
nighttime operation to allow safe movement about the cab without reflections.
d) Intensity control. All lighting for administrative work,
operation of controls, and instrument reading shall be compatible with
installed equipment and shall have adjustable intensity controls.
