The Characteristics Of A Good 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.

Before a flight device can land onto the runway, there are very many things that must be in place. One of them is the angle at which the plane is gliding in. Getting this angle wrong is very risky as the device might crash into the ground and cause damages. Luckily enough standard visual approach lights are installed to direct the pilot on this issue. These devices are placed on one line along the length of runway.

Another set of powerful lamps is also installed at a ninety degree inclination from the runway path. This part requires at least four separate lamps to be put on the left bank of pathway also. Determination of distance of approach from an aerial point in space is not the easiest thing despite intense training. The pilot therefore uses these precision approach path indicators to approximate the glide approach distance.

An airport has to be equipped with a pulsating visual approach slope device too. Unlike the others, this one comprises of a single box structure. It is mainly located at air-parks, heliports and 139 airports as well. The significance of this mechanism is to show descent. The lighting is either solid white for effective descent profile or red for an improper profile.

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.
