CHAPTER 11: PORTABLE EMERGENCY LIGHTING
11-1
GENERAL REQUIREMENTS
In times of emergency, when standard airfield lighting is not available and aircraft
operations must be performed at night, it may be necessary to resort to the use of
portable lighting devices to support the operations. The lighting design standards
contained in this section may be suitable for use in VFR night operations but do not
qualify the airfield for instrument operations of any kind. The standards in this section do
not apply to requirements for forward tactical airfields or landing zones. See AFI 13-217,
Assault Zone Procedures, for guidance on those requirements. Care should be taken
when installing portable lights that they are secured sufficiently to prevent movement as
a result of jet blast or other forces. When application of the criteria in this section would
result in a light location in an active paved area, the light must be omitted or relocated
as circumstances dictate. Information on the Emergency Airfield Lighting Systems

RUNWAY LIGHTING
11-2.1
Runway Edge Lighting
Portable edge light configurations generally follow the standard configuration except that
the spacing may be a maximum of 90 meters (300 feet) and the offset may be a
maximum of 3 meters (10 feet) from the runway edge. The runway edge lights must be
white.
11-2.2
Runway End and Threshold Lighting
The number of lights required for runway end and threshold lights is reduced to 10. At
each end of the runway they must be placed in two groups of 5 with the outermost lights
in each group in line with the line of the runway lights spaced at 3 meters (10 feet)
intervals toward the center. The line of threshold and runway end lights may be offset
no more than 1.5 meters (5 feet) from the end of the runway. The lights must be red
toward the runway and green toward the approach.
11-3
TAXIWAY EDGE LIGHTING
The techniques for designing an emergency taxiway edge lighting system are generally
the same as for a standard system except that the spacing is increased as follows:
11-3.1
Straight Sections
The spacing must not exceed 66 meters (220 feet).
11-3.2
Curved Sections
The spacing must not exceed 30 meters (100 feet).
