Do Airplanes dump toilet waste in Air?
No, they do not. Each plane has a 200-gallon tank, where all the sewage is collected. For the last three years, the aircraft has vacuum toilets, which separate the water and sewage.
When the airplane lands, a particular truck comes, and the waste stored in tanks is emptied into the truck.
And then this waste disposes of in the airport’s sewage system.
The crew members or Pilot can’t dispose of the waste in the air as these tanks are situated outside the plain, and only the ground crew can open them.
