Why do airplane toilets not have water?

Airline toilets work on vacuum. The system has a vacuum pump, or actually open to the outside, and the resulting vacuum draws the contents of the bowl into a storage tank. So there is no flow of water to fail, resulting in a clog. Vacuum is much more reliable, especially at 30,000 ft.

Why is it bad for you? Airplane tap water is stored in on-board tanks that house the liquid for tea, coffee, and to service the restrooms. These tanks are often stored without cleaning for long periods at a time, leading to the potential build-up of bacteria in the stagnating water.

They don't use very much water. Instead of using water and gravity, they use a partial vacuum. That accelerates the water and the waste at high speeds ... up to 150 metres per second — or 300 miles per hour — in order to get the waste down to the waste tank.

There is a valve on the storage tank that opens when a toilet is flushed and closes when the toilet is not in use – to prevent odours from leaving the tank. This helps to keep the smell down from so many people using the toilet during a flight. The blue chemical helps to keep the smell down as well.

While fuel dumps don't happen every day, they're also not uncommon. Nor do they usually represent a major emergency. In fact if an aircraft is taking the time to dump fuel before landing, that's likely an indication that the issue forcing the plane to land is serious but not critical.

This is what they are actually doing to prepare for the best outcome should there be an emergency evacuation. They are preparing to save lives.

Why? Answer: The maneuver you describe is usually either a 360 degree turn issued by the air traffic controller to increase spacing between your flight and another airplane, or it was one turn in a holding pattern. The one turn in a holding can occur when the expected hold time is reduced, requiring only a single turn.

The simple answer is yes, pilots do, and are allowed to sleep during flight but there are strict rules controlling this practice. Pilots would only normally sleep on long haul flights, although sleep on short haul flights is permitted to avoid the effects of fatigue.

MORE DETAILS

The distinct smell inside commercial airplanes is often attributed to jet fuel. During flight, commercial airplanes burn a mixture of jet fuel and oxygen in their engines to produce propulsion. When jet fuel burns, it creates odorous vapors that may enter the cabin.
