OTHER AUXILIARY LIGHTS
10-4.1
Special arrangements of lights, such as apron or parking are floodlights
and protective and security lighting, may be required at an installation. These lights will
not be connected to the airfield lighting circuits. Hangar access aprons (hangar
entrances) may be lighted by floodlights installed around the apron or mounted on the
hangar. For maintenance operations, outlets will be provided for use by portable lighting
equipment. Floodlights and outlets provided for these areas are considered as part of
the hangar construction.
10-4.2
Floodlights
10-4.2.1
Fixed Floodlights Glare Control
Direct lamp light from the floodlights will be avoided in the direction of a control tower
cab and landing and departing aircraft. Aiming of the floodlights should be, as far as
practicable, in the directions away from a control tower cab and landing and departing
aircraft. Direct light above the horizontal plane through a floodlight must be avoided. To
minimize direct and indirect glare, the mounting height of the floodlights should be at
least two times the maximum aircraft eye height of pilots of aircraft regularly using the
airfield. Also, the location and height of the masts should be such that inconvenience to
ground personnel due to glare is kept to a minimum. In order to meet these
requirements the floodlight light distribution may have to be restricted by use of glare
shields.
10-4.2.2
Fixed Floodlights Design Considerations
Floodlight masts must meet relevant obstacle clearance requirements. Locate and aim
the floodlights to minimize shadows. Horizontal illuminance should have a uniformity
ratio (average to minimum) of no more that 4:1.
10-4.3
Lighting Intensities
The various areas of the airfield, heliport, or helipad requiring normal and/or protective
floodlighting will be lighted to meet the following minimum intensities in footcandles, in
the horizontal plane.

* NOTE: Outlets for power and lighting should be installed at this area to supplement
the lighting intensity at the work area and to focus light on the part of the aircraft being
served.
