Federal Law allows an EXCEPTION for laser emergency signaling devices to send a distress signal to aircraft.
In February 2012, the United States Congress passed into law HR658 authorizing appropriations for the Federal Aviation Administration (FAA) for fiscal years 2011 through 2014. Included in the law is Section 311 "Prohibition Against Aiming a Laser Pointer at an Aircraft". Section 311 39A(c)(3) on page 56 specifically exempts "an individual using a laser emergency signaling devices to send an emergency distress signal." Greatland Laser has sold its patented laser emergency signaling devices throughout the world for over 10 years. We have never had a safety issue with the products. Under the exception provided in this federal law, Rescue Lasers are legal to signal an aircraft for help in an emergency.
For an explanation as to why the Rescue Lasers are safe when a standard laser pointer can cause problems, please refer to "How Do They Work".
