The price barrier that may limit access to certain technological developments is increasingly disappearing, in particular in rich, highly developed countries. More and more newly developed devices reach the market very quickly and are available to almost everyone. Scientific and technological progress is becoming more and more noticed by every person. It was shown that even typical 1 mW laser pointers may still distract the aircraft pilots during landing or take-off which may have adverse consequences. Laser pointers characterized by powers of up to 50 W as well as these with typical powers of several mW were considered. The presented analysis may be a supplement to the AC 70-1B document and may serve as a sample approach for those who need to deal with such laser sources.
The impact of ellipticity of the beams on the calculated distances was shown. Proposed in this article calculation method was extended to multi-beam radiation sources characterized by different wavelengths, different divergences in two perpendicular planes and different powers. FAA’s calculations and presented examples are simplified for the most common cases of a single circular beam, or circular beams sharing the same power, divergence and aperture. Federal Aviation Administration in the AC 70-1B document, essential for the flight safety in the case of illumination of aircraft pilots by laser radiation.
The article describes the way to calculate the distances, defined by the U.S.
