Welcome. This site is provided as a service to the airport
lighting industry by Visual Aids Services Incorporated (VASI). The site
aims to help raise the level of competence in the design of airport lighting
systems by providing an industry-wide forum for the exchange of ideas,
information and experiences. We hope this will benefit the industry and,
in the longer term, ensure a safer environment for air travellers.
The success of the site depends on the active participation of all sections
of the airport lighting industry. You can participate in several ways.
The forums allow you to
discuss topics of current concern or to ask questions of colleagues in
the industry. You can submit
articles and news items for publication on these pages and, if you have
comments about our activities or the site in general, you can give us
your feedback.
FAA Advisory
Circulars: call for comments
The Federal Aviation Authority (FAA)

LEDs and power distribution systems for airport lighting
Optimus Corporation and Veracity
Engineering, support contractors for FAA AND 520 have
prepared a paper on what new power distribution system(s)
should be considered for the future. This task evaluates
the options available for airport lighting power distribution
circuits when the circuit contains all low wattage light
units such as available today with LED light sources.
The potential cost savings offered by the new very efficient
light source can be fully realized only when the power
distribution circuit and the power supply are designed
for this lower power environment. read more...
