With the growing popularity of high power green laser pointers, there are more and more reports of lasers being pointed at airplanes and helicopters. In 2008 alone there are a number of reports that received widespread publicity media. One of these cases in the capital of United Arab Emirates Dubai, two Arab men were charged, tried and convicted with a laser beam aimed at an aircraft during landing.
Exposure of these cases have received has led to a series of misconceptions and misunderstandings on green laser pointers and their danger to aircraft. The purpose of this report is to separate fact from fiction.
Information basic lasers
It is very simple laser beams are very concentrated and narrow beams of light and lasers can be widely measured in tens of kilometers. A high power green laser pointer can have a range of 20-30 miles, but shall have no power or be very dangerous in this range. Even the best quality laser will a ray that grows in size 10 cm per 100 meters. When the laser beam covered a kilometer, the beam will be the size of a door way and be unable to cause any damage or injury.
green laser pointers not red, blue or orange laser pointers are the main laser targeting aircraft because green is much more visible to the human eye than the other colors. The other reason is the blue laser and laser orange are too expensive and relatively low power to make use of the board.
Real and imaginary dangers
There are not available in the market and very few, if any, military lasers that can do physical damage to aircraft. The three main concerns and dangers to a pilot's vision to bring laser pointers green planes is a distraction, causing glare and temporary blindness flash. A fourth concern is eye damage, but this is much less likely.
It is highly unlikely that any of these four dangers that result in loss of aircraft or life. These hazards occur only when a person deliberately points and tracks an aircraft with a green laser pointer. These dangers also only occur when an aircraft is taking or landing and the plane is at a height low enough for a laser to strike the cab.
In brief
For the laser hobbyist not deliberately target an aircraft, green laser pointers are safe to use outdoors in the evening. A good rule when pointing lasers in the sky heaven is first check to make sure it is free from the aircraft and avoid using green laser pointers airports.
For people who think green laser pointers to point out, is a federal crime in the U.S. and rightly so. Lasers are very easy to follow and offenders face heavy fines and significant prison sentences. Drawing aircraft lasers is also a criminal offense in many other countries.
