The Properties Of An Effective Slope Indicator

By Betty Williams


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.

The lighting system at the airport is not just random or for the good look. Each and every illumination availed at this place has a very strategic purpose to serve in the overall effectiveness of airport operations and safety. These various signal measures put in place are generally referred to as slope indications. There are very many types of fluorescent installed at these premises and each one of them sends a unique signal to the pilot and other operators as well.

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.

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.

Timely carrier services are very paramount at the airport. Any delays in this system can lead to great frustrations. Care should be taken however as for the carriers not be found out of place during landing. The direction of these carrier controls is done by stabilized glide slope pointers. They are modeled to create a strong beam of illumination that informs the control system on timing aspects.

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.
