What happens when you flush an airplane bathroom?

Aircraft toilets work using a clever combination of engineering and physics. When a passenger flushes, a powerful vacuum system draws waste into a holding tank. This vacuum mechanism not only saves space but also minimizes odors by reducing the exposure of waste to the air.

The toilets are loud on airplanes because they use the pressure difference between the inside and the outside of the aircraft in order to flush them. 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 ...

Fortunately, if passengers do become trapped in the toilet, cabin crew can help from the outside. There is a hidden latch behind the lavatory or no smoking sign on the toilet door. The sign can be flipped up, enabling flight attendants to slide the hidden latch in the case of an emergency.

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.

A buzzer sounds, and the pilots must switch the door control inside the cockpit to “unlock” to release the door after verifying the crew member through a peephole or video surveillance. If the pilots become incapacitated, a flight attendant can use a special code to activate an emergency access entry system.

Maintain Pilot Staffing Levels: Two Pilots on the Flight Deck Keep the Skies Safe. Commercial aviation is the world's safest mode of transportation, and history shows that having at least two fully qualified, highly trained, and well-rested pilots on the flight deck is an airliner's strongest safety asset.

FAA allows it, passengers learn. The Federal Aviation Administration regulates the type of coffee pots that can be used on planes, and requires ashtrays in or near lavatories, though smoking is now banned on flights.

Passengers sometimes want to sit there in flight to see what it's like, but it is against Federal Aviation Regulations. The FARs require pilots to remain in their seats except when duty requires they be elsewhere or when nature calls. Conyers did say there are advantages to having a passenger up front occasionally.

Long and short distance pilots are allowed to use the bathroom when they need to as long as the airplane is under control. Pilots use the same bathroom as the passengers, much to the delight of the younger (and sometimes older) people on board!

Major carriers generally place importance on cleanliness and use industrial machinery to wash and dry blankets. Some airlines may still provide unwrapped blankets or blankets that have been refolded and reused.

There's no fixed number – each individual is unique, as is the ejection that they endure. After ejection, a pilot will be given a full medical evaluation and it is down to that medical professional to advise whether it is recommended that the pilot continues to fly or not.
