Air transportation is the fastest way for a person to travel between distant places. This is especially if these places are separated by large masses of water. The actual process of executing air travels is quite complicated. It requires not only highly trained personnel but also very effective means of sharing information. Slope pointers are lighting mechanisms used to send quite a wide range of information to the pilot without verbal interference. The traits of a proper slope indicator are highly crucial.

This device is also very paramount in determination of benchmark height for a proper landing procedure. Being human, at times the controller of plane aligns it a bit too high or low for a safe landing. There are numerous kinds of such devices depending on the kind of plane and airport set up as well. The situation of these devices is just as important as any other safety measure undertaken to ensure passenger safety.

When the plane has approached the airport and is seeking to make a landing, the glide angle is very crucial. This is not information that can be gotten from the system controls. The pilot simply has to focus on the visual approach indicator. This illumination system is positioned in line at the sides of the runway. The projected illumination varies between white and red basing on the glide angle of approach.

The precision approach path indicator is also another category of runway management lighting. This device is made up of up to four separate lighting systems. These lamps are aligned perpendicularly to the path of approach. Normal procedure stipulates that they should be situated at the left side of runway. Their purpose is to determine proximity of glide slope of plane. It uses a combination of white and red illuminating to direct the pilot accordingly.

Doing without pulsate visual approach slope indication at the air-parks, heliports and others is almost impossible. This can lead to crash-landing at this place. This special box is designed to transmit information concerning the angle of descent to the pilot. Information concerning descent profile can only be channeled to the pilot effectively using this device.

Aviation in the past depended upon tri-colored VASI lighting to determine glide slope. This has one fluorescent that varied between green and red illumination. The red illumination indicated that the plane was below required level while green meant above. An integration of two colors gave an amber reflection that was used as the benchmark. Variation in visual properties however made understanding this system an ambiguity for most pilots. This system was quite problematic however.

Aircraft carriers are very important mechanisms at the landing site as well. Without proper communication however, they can cause catastrophic accidents. This is why a beam of illumination was designed to send information to the controllers through signals. This technology is technically known as the stabilized glide gradient indicator.

The t-visual indicators have the highest number and are designed to have a varying visual effect on the pilot in accordance with their point of runway approach. These lamps are placed at the sides of pathway in a crosswise format. When at the right approach to the runway, the point will see a T-formation on the ground.
