Whenever you look up into the night time sky you will often see the navigation lights of aeroplanes as they fly overhead. These are the same types of planes that you see at any airport. The navigation lights look quite high off of the ground in the daylight. So if you are wondering how a filament might be changed, the answer is by making use of an aircraft maintenance ladder.
You will notice that the aeroplanes are made by different manufacturers, and so their dimensions will be different. Due to this the equipment that the engineers use to help service the planes need to be either adjustable or different sizes. Another consideration is that they need to be moved easily.
Since these planes are all of various heights an engineer will require access to various heights too. The most common way that can be achieved is by using a simple piece of equipment called an 'A' frame step set. If the engineer were to stand on the upper step he would have gained 6 feet.
The basic construction of these steps is mainly from strong, but light, aluminium. This material, coupled with wheels at the bottom of the legs on one side, ensures that these steps can be easily moved by just one person. The wheels are made from hard wearing nylon, which will cope with the daily use, and there is no chance of any sparks.
The treads of the steps will have headless dimple shapes on them. Not only does this cut down on the weight of the steps, but also serves as a safety feature. When the person involved in maintaining the aeroplane is stood on the steps their footing will be stable, as thanks to these dimple shapes their safety shoes will not slip.
Once the legs are in the fully open position the steps are very stable. Immediately beneath the uppermost step there is often a flap which will fold down to form a tray. The engineer can then utilise this tray to hold his tools, and so he will have both hands free to complete his task. With his required tools with him the job is completed more quickly.
Just by standing on different steps the engineer can now access the different levels, and there is no need for him to step on the airframe. If you stand next to a plane you will see that the surface has a polished appearance. This surface needs to be kept in good order, as this in conjunction with the plane's forward motion assists with the plane's ability to fly smoothly through the air.
It might be obvious that even the tallest engineer stood on the top step will still be unable to reach the top of the tail on a passenger jet. As you might imagine there are different designs of steps to cope with this. Some have a larger work platform at the top, but due to the working height they will also be surrounded by a safety railing.
So an aircraft maintenance ladder needs to fulfill several factors. It has to be easy for one person to move and set up. It needs to be safe to use, both for the individual and for the plane being worked on.
