Potential Flight Hazards

Sufficient dischargers must be provided to allow for

current−carrying capacity which will maintain

airframe potential below the corona threshold of the

trailing edges.

h. In order to achieve full performance of avionic

equipment, the static discharge system will require

periodic maintenance. A pilot knowledgeable of

P−static causes and effects is an important element in

assuring optimum performance by early recognition

of these types of problems.

7−5−12. Light Amplification by Stimulated

Emission of Radiation (Laser) Operations

and Reporting Illumination of Aircraft

a. Lasers have many applications. Of concern to

users of the National Airspace System are those laser

events that may affect pilots, e.g., outdoor laser light

shows or demonstrations for entertainment and

advertisements at special events and theme parks.

Generally, the beams from these events appear as

bright blue−green in color; however, they may be red,

yellow, or white. However, some laser systems

produce light which is invisible to the human eye.

b. FAA regulations prohibit the disruption of

aviation activity by any person on the ground or in the

air. The FAA and the Food and Drug Administration

(the Federal agency that has the responsibility to

enforce compliance with Federal requirements for

laser systems and laser light show products) are

working together to ensure that operators of these

devices do not pose a hazard to aircraft operators.

c. Pilots should be aware that illumination from

these laser operations are able to create temporary

vision impairment miles from the actual location. In

addition, these operations can produce permanent eye

damage. Pilots should make themselves aware of

where these activities are being conducted and avoid

these areas if possible.

d. Recent and increasing incidents of unautho-

rized illumination of aircraft by lasers, as well as the

proliferation and increasing sophistication of laser

devices available to the general public, dictates that

the FAA, in coordination with other government

agencies, take action to safeguard flights from these

unauthorized illuminations.

e. Pilots should report laser illumination activity to

the controlling Air Traffic Control facilities, Federal

Contract Towers or Flight Service Stations as soon as

possible after the event. The following information

should be included:

1. UTC Date and Time of Event.

2. Call Sign or Aircraft Registration Number.
3. Type Aircraft.

4. Nearest Major City.
5. Altitude.

6. Location of Event (Latitude/Longitude and/

or Fixed Radial Distance (FRD)).

7. Brief Description of the Event and any other

Pertinent Information.

f. Pilots are also encouraged to complete the

Laser Beam Exposure Questionnaire located

on the FAA Laser Safety Initiative website at

http://www.faa.gov/about/initiatives/lasers/

and submit electronically per the directions on the

questionnaire, as soon as possible after landing.

g. When a laser event is reported to an air traffic

facility, a general caution warning will be broad-

casted on all appropriate frequencies every

five minutes for 20 minutes and broadcasted on the

ATIS for one hour following the report.

PHRASEOLOGY−

UNAUTHORIZED LASER ILLUMINATION EVENT,

(UTC time), (location), (altitude), (color), (direction).
EXAMPLE−

“Unauthorized laser illumination event, at 0100z, 8 mile

final runway 18R at 3,000 feet, green laser from the

southwest.”

REFERENCE−

FAA Order JO 7110.65, Paragraph 10−2−14, Unauthorized Laser

Illumination of Aircraft

FAA Order JO 7210.3, Paragraph  2−1−27, Reporting Unauthorized

Laser Illumination of Aircraft

h. When these activities become known to the

FAA, Notices to Airmen (NOTAMs) are issued to

inform the aviation community of the events. Pilots

should consult NOTAMs or the Special Notices

section of the Chart Supplement U.S. for information

regarding these activities.
