When you fly on a plane, you may feel that the toilets on the plane are no different from the ones we usually touch.
But in fact, the small bathroom contains many secrets!
For example, airplanes are non-smoking but there is an ashtray in the toilet; the door of the toilet can be opened from the outside after being locked.
Today, I will tell you about this indispensable facility on the plane-the toilet.
1. It consumes fuel to go to the toilet on the plane?
Earlier reports pointed out that according to the toilet flushing cost 5 liters, passengers will use 1 liter of fuel to use the aircraft toilet once.
In fact, this statement is not accurate. Using the toilet on the plane does not consume so much fuel.
The flushing of the toilet on the plane relies on pressurization to transport the water from the water tank to the toilet, and then it is flushed by vacuum. There is a vacuum motor near the water tank to create a vacuum environment, so the flushing mainly depends on electricity.
The electricity on the plane comes from two generators in flight, and the fuel consumption of the generators in flight is negligible. Aircraft fuel is mainly used for the combustion of the engine’s core engine to generate thrust, which in turn drives the aircraft to fly.
However, I still appeal to my friends, if you are flying for a short distance of one or two hours, it is better to go to the airport toilet before boarding. You can use the toilet less once on board, which is also your contribution to environmental protection.
2. Where did the things flushed out of the toilet go?
After going to the toilet on the plane, will everyone consider a question: Where does the flushed poop go?
I believe many people have thought about whether these excrement are washed down the water directly, and then they don’t know where they have gone. The answer is of course: no!
With the continuous development of technology, the aircraft has long been upgraded from the original “in-line” history to the current vacuum toilet exhaust system.
For the waste in the toilet, the high-pressure airflow generated by the vacuum sends them to the storage tank in the abdomen of the aircraft, and is processed by adding blue chemical substances with deodorizing and decomposition effects.
The on-off valve of the storage box is located outside the fuselage, which ensures that the excrement can only be recovered by the ground crew to the disposal vehicle after the aircraft has landed, and will not be “spattered” in the air.
3. Can the outside be opened after the door is locked?
Every bathroom on the plane has an unlocking device on the door. Of course, ordinary passengers don’t know how to unlock the door outside. Only the flight attendants know the correct operation method, so you don’t need to worry about it.
If a passenger faints in the toilet or other situations occur, the flight attendant can open the door to rescue the passenger.
Of course, if you smoke secretly in the toilet, the stewardess has the right to unlock it from the outside and rush in, so you must not do anything bad in it.
4. Why is there an ashtray in the toilet?
Everyone knows that smoking is forbidden on the plane at all times. However, a careful friend may find that there are still ashtrays in the toilets of the aircraft. What is the reason?
According to regulations, ashtrays in aircraft toilets are mandatory equipment within the scope of flight safety.
The ashtray is mainly used to prevent passengers from secretly smoking cigarettes and throwing cigarette butts into the trash can to cause a fire.
But don’t get lucky, because the airplane toilet is equipped with a sensitive smoke detector. Smoking will trigger the alarm to sound, and the air police will come and take you away immediately.
5. Are the aircraft toilets clean?
As a facility on public transportation, many passengers worry about the sanitary problems of airplane toilets.
What I want to tell everyone here is: the aircraft toilet is absolutely clean and hygienic.
Civil aviation aircraft uniformly use vacuum toilets, with strong suction, and only a small amount of water can be used to flush dirt very cleanly.
In addition, after the flight, there will be professional cleaning staff who will collect and clean up the dirt.
And on the plane, the stewardess will clean regularly to provide everyone with the most comfortable travel experience.
6. The difference between toilet door and emergency hatch
Earlier, when a flight from Nanjing to Nanchang was about to take off, a female passenger used the emergency cabin door as a toilet door. As a result, the slide bag rushed out of the cabin.
This action resulted in the release of the aircraft’s emergency slide package, resulting in a two-hour delay of the aircraft, and the passenger was sentenced to administrative detention for 10 days.
My friends may ask, how should the toilet door be distinguished from the emergency hatch?
①Toilet door: There is a red non-smoking sign on the door, located in the middle of the cabin, next to the cabin passage.
②Emergency cabin door: There are many red warning signs on the aircraft door, which are large in size and flush with the fuselage wall. There are usually flight attendant seats and emergency equipment next to it.
