There are very many means of transport and communication. Air transportation however is the most effective among them. Operating an airplane and airport is not an easy venture. Effective communication is very important. The air space control chamber usually directs the pilot verbally through systems in plane. The use of light indication is very paramount in this process as well. The characteristics of a good slope indicator are quite numerous.

Due to the vast nature of information that must be shared, several kinds of pointers have to be deployed to ensure that each and every piece of data is sent and received in time and also prevent confusion. In this sense therefore, a good number of illumination mechanisms were developed and placed strategically at the airport. This allows the control panel to effectively play their role of plane management.

The visual approach indicator is one of its kind. It is positioned at the banks of runway. It serves as a system of illumination that illuminates either white or red. The color that one perceives will depend on their point of view. Provision of approach guidance information is the sole purpose of this device. These lamps are designed to be visible from a long range of distance of up to thirty two kilometers during the night.

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.

Small and other special kinds of flight modules usually have no ascension or descending angle determination mechanisms. This makes it hard for the pilot to effectively align them with the pathway while seeking a safe landing. For this reason, heliports, air-parks and 139 airports are equipped with a special box known as Pulsate visual approach gradient indicator.

The tri-colored VASI is a technology that has fallen out of use in recent times. It was designed to indicate either red or green depending on the ascending or descending properties of plane. A mixture of these colors however provides an amber result that most pilots misinterpreted as a sign of wrong inclination. This made them to react un-accordingly. Due to incidences, the system was put to halt.

Another crucial airport control crew function is the manipulation of carrier activities. Without knowledge on the location of plane before landing however it is very hard to properly allocate carrier services especially for busy airports. Stabilized glide gradient indicators are designed to create a beam upon plane approach. This beam varies in color to indicate location and urgency for these services.

T-visual approach slope pointers make up the majority of lighting devices at the airport. This is because they are twenty in number and are all arranged along the runway banks in variable sequences. These sequences have different visual effects according to the degree at which the plane is moving towards them.
