Toilets in airplanes: features of the device, scheme and rules of operation

Toilets in airplanes are a very important detail of comfort, especially for long flights. Let's see how they work and how to use them correctly.

Are there restrooms in the airplanes?

Of course, even in the smallest passenger airbus there is a toilet. This is a necessity for comfortable flight of passengers to the destination. The bathroom is equipped with sewerage and water, which is necessary for personal hygiene. The toilet itself is quite small in size. It houses a toilet, a sink, an urn for used toilet paper and other hygiene products, and in some there are also boards for changing babies. Special mini children's tables are reclined and fixed if necessary. In some modern types of aircraft there are also latrines for disabled people.

How it works?

Many are wondering about how the toilet is arranged in an airplane. As a rule, these are biotoilets, all waste from which are collected in special tanks. The volume of these tanks can vary - from 115 to 270 liters. To prevent unpleasant odor throughout the cabin, special chemicals are added to this container, which disinfect water and eliminate stench. The cargo from waste life is stored in the aircraft throughout the flight. Some people think that after washing out, all impurities are sent to open space, but this is an erroneous opinion. The tank or tank, which gradually fills up, after landing , is extracted, transported and disposed of.

What problems can arise?

Sometimes toilets break down in airplanes. The main cause of trouble is the human factor. Someone in ignorance, deliberately or accidentally, can drop anything in the toilet. If this thing turns out to be large, the aerotechnicians have a lot of work. After all, this is not a home plumbing, with which you can quickly cope and solve the problem in a few minutes. This is a serious system, the slightest fault which disables it for a long period of time. Therefore in the toilets in large letters on the tablets are words that it is necessary to be extremely cautious, and for used diapers and feminine hygiene means there is a trash container, which is strongly advised to use.

When the aircraft arrives at its destination, a car with a large corrugated hose approaches it without slowing down. It connects to the opening of the tank, in which the whole flight collected wastes of life. At this point, an unpleasant problem can also arise. If the connection is incorrect or of poor quality, the hose can break off and all contents will simply pour into the airport workers. Another problem can arise if something sticks to the walls of the tank or tank. In this case, a serious washing of the entire system is required. Therefore, before sending something to the toilet something forbidden, remember how to use the toilet on the plane. Also think, how many troubles and inconveniences it can cause.

Terms of use

If you are flying for the first time and do not yet know how the toilet works in an airplane, do not hesitate to ask flight attendants about it. They will tell you how to use the restroom properly:

• The door is opened by pressing the handle located directly under the signboard with the inscription Lavatory.
• If the toilet is already occupied by someone, the inscription is highlighted in red. If it is free and available - green.
• How is the toilet in the airplane? Not much as we are used to. Therefore, you can only visit it during the flight after the climb. It is strictly forbidden to use it during take-off and landing. Also, when recommending to take their places, for example with turbulence, the toilet should be left immediately.
• Visiting latrines on airplanes is recommended 10 minutes before meals and drinking or 15 minutes after eating.
• In the toilet itself it is forbidden to throw paper, gaskets and other hygiene products. To do this, each toilet has special urns.
• Some lavatories are equipped with a special tilting board for changing small children. What toilets in the aircraft have it, check with the flight attendant, especially if you are traveling with a small child.
• Since the waste is washed away by a powerful, powerful jet of air, before this procedure it is necessary to check whether the lid of the toilet bowl is lowered.
• The toilet is not allowed to smoke, as there is a special fire alarm, which works even with the slightest smoke.

Where does the noise come from?

Some passengers may think that when the water is drained in the airplane toilet, a characteristic noise is heard, similar to a brief depressurization in the cabin. However, this is only an illusion, since waste is not thrown out into the air at all, but is sent to a special sealed tank. In addition, water is not drained because it is extremely uneconomical. Therefore, waste of life is removed by a powerful directional air flow, which causes a sound like depressurization.

Where are the toilets in airplanes of different brands?

In different airbuses, the restrooms are located in different places. Also differs and their number:

1. In the popular "Boeing-737", as well as in the TU-154 and A-320 there are three toilets. One of them is located at the entrance to the plane, both others are in the tail.
2. In the huge Boeing 767, there are five toilets. Two of them are in economy class. One is available at the start of the business zone. Two more - in the aisle between them.
3. Toilets in airplanes of the Boeing 747 type are located two at the end and at the beginning of the airbus. Four are in the middle and three more on the second deck. Totally there are eleven of them.

A bit of history

In various countries, when designing toilets in military aircraft, invented sewerage and water supply systems. At the same time, in most of such aircraft in the USSR and Russia there are no toilet rooms. For small needs, each crew member has a special urinal, which is hermetically sealed. At the same time "by and large" there is nowhere to go. Some military transport planes still use conventional buckets and plastic bottles. Now you know almost everything about how a toilet works in an airplane and what rules exist for using it. Fly with pleasure!
