One of the fastest and hence most popular transport means is the use of an aircraft. The risk of collusion with buildings and other structures like radio masts is imminent. One thing that tries to reduce this risk is the aircraft warning lights on buildings together with other soaring threats of impact.
These devices have specific features that are regulated by national and international standards. This standards act like guidelines proving for the intensity, size, color location and beam pattern of lights. This means that the light beam pattern of one nation will differ from another. An experienced pilot would be able to tell a nation he is in by just observing the warning lights.
The Federal Aviation Administration and International Civil Aviation Organization are the mostly used regulations standardizing the set up and installation of lamps. The first is a bureau of the transport division of America while the latter is a special bureau in United Nations. These standards are what are majorly used in standardizing the lights worldwide
There are various types of warning lights each has special feature and area intended for use. Obstruction lights use red lamps use incandescent filament bulbs or an array of a high power red LED to constantly light obstructions during the night. High intensity white strobes are used during the day to make obstacles more visible,
Another type of warning system tries to combine these two, by using red beacons during the night and xenon flasher during the day time. This double system has a merit in that if one beacon is should stop working then other would assume its roll. This is a preventive measure that limits risk of collision.
The most important advantage of the warning devices is that they save life and prevent destruction. They also help pilots to navigate with ease in times of low visibility for instance during heavy rains. Because most have their own power supply they will remain operational even is there happens to be a blackout. The use of green energy to power the devices may go a long way in reducing the carbon footprint.
There also disadvantages of using this lights. The lights are not full proof as they are still dependant on the vision of the pilot. They also may be not visible in times of intense fog. Light pollution from the lights may also be a real nuisance to the people living near it. Those that use diesel generators as a power source cause intense air pollution. In addition to this they also kill birds which collide with them. Another risk is that they may have a malfunction at any moment and leave the pilot blind.
As the knowledge of man continues to increase, so does the level of technology. This devises will soon become obsolete and another new invention be adapted. Even though this devises may have some disadvantages. The number of human lives that have been saved by using it is what makes use still relay on them.
