how Jumbo jets maintain their Center of gravity with freshwater and sewage needs on board

Question

So i worked on a ship and i know we had various tanks that could be filled and emptied to modify our CoG

in an airplane that could be extremely dangerous and could have several thousand kilo’s of sewage after a long flight how do they maintain such a critical factor for flight?

Answer 1

I got to wondering about something like this when the captain announced that we were going to be landing soon. he suggested that you visit the lav now if you need it since the seatbelt light will be going on in a few minutes.

I was sitting near the center and at least 1000Kg of passengers headed to the rear lav. I wondered if they could feel that shift if they were hand flying.
