So This Is Christmas

Merry Christmas is such an infectious feeling I like to feel that way all year around.

So if you are visiting just before Christmas, just after Christmas or even here on Christmas day I am sure you will find something of interest for you and in the spirit of Christmas.

It may be said that Christmas is no longer a celebration but this must be spoken by people that have never had trouble closing their eyes on Christmas Eve in an expectation of what maybe left for them on the carpet under the tree.

I continue to look forward to the surprise on my Grandchild's faces to this day at Christmas events.

Merry Christmas - Merry Christmas - Merry Christmas

The Traits Of A Proper 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.

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.

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.

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.
