Chapter 30. High Intensity Light Operations

Section 1. General

30-1-1. PURPOSE

This chapter prescribes policy and guidelines for determining the potential effect of high intensity light activities on users of the NAS.

30-1-2. POLICY

Consideration must be given to commercial, general aviation requirements as well as to the public right of “freedom of transit" through the airspace. Accordingly, while a sincere effort must be made to negotiate equitable solutions to conflicts over the use of the NAS for non-aviation purposes, aviation must receive primary emphasis.


The provisions of 49 U.S.C. Sub Title VII, grants the Administrator the authority for aviation safety. That authority has been delegated to air traffic and Flight Standards with the associated responsibilities to evaluate activities that can potentially affect aviation safety in the NAS.


The terms used in this chapter are defined below:

a. High Intensity Light (HIL). A lighting system other than laser light designed to penetrate the navigable airspace.

b. HIL Manufacturer. A term that refers to persons who manufactures high intensity light emitting products. This includes those who are engaged in the business of design, assembly, or presentation of a HIL activity.

c. HIL Operator. A knowledgeable person present during HIL operation who is responsible for ensuring compliance with applicable safety standards; monitoring the safe operation of a HIL operation; and can effect termination of the HIL promulgation in the event an unsafe condition becomes apparent.
