Quiz Me: Visual warning system

July 1, 2013

Here's an edited question asked by an AOPA member who contacted our aviation services staff through the AOPA Pilot Information Center. Test your knowledge.

Question: What is the visual warning system (VWS)?

Answer: The VWS signal consists of highly focused red and green laser lights designed to illuminate in an alternating red-and-green signal pattern. These lasers may be directed at specific aircraft suspected of making unauthorized entry into the Washington, D.C., Special Flight Rules Area (DC SFRA) proceeding on a heading or flight path that may be interpreted as a threat or that operate contrary to the operating rules for the DC SFRA. Read more in the Aeronautical Information Manual Section 5-6-6. And take the DC SFRA online training course.
