Airfield Lighting Requirements

So many light at so much power is required by law on runways.

Airfield lighting requirements are put into place for the safety of pilots, passengers and personal working at the airfield. There are many issues that need to be covered when setting up and installing airfield lighting–like transformers, light fixtures, underground wiring, controls, regulators and other equipment associated with developing an airfield lighting system.

Airfield Lighting Cable

Airfield lighting cable should conform to FAA regulation AC 150/5345-7. Also, series airfield lighting cable should be unshielded.

Cable Tags

Cable tags should be provided for every cable or wire at the duct entrances that are entering or leaving a manholes, handholes and at each terminal within the lighting vault.

Heliport Light Beacon

Under the FAA Advisory Circulars 150/5345-12, the heliport light beacons are required to have flashing lights coded white-green-yellow. Under FAA regulations they must also be able to operate in environmental conditions with wind velocities of up to 100 mph, withstand exposure to wind-driven rain and snow, and be able to withstand at least 1/2 inch of accumulated ice.

Obstruction Marker Lights

Obstruction marker lights are mainly used for tall structures that may cause a hazard to air navigation. Under FAA AC 150/5345-43 they must emit a steady burning aviation red.

Runway Distance Markers

Runway distance markers must be white or yellow numerals that are on a black background. They must conform to FAA AC 150/5345-44 standards.

Approach Lighting System

The approach lighting for airports need to follow sequence flashing as set forth by FAA AC 150/5345-51. They must also have a backup power supply that will deliver continuous power to them within one second of a power outage.
