pressurisation systems in cargo room
 

I am trainee. Can I ask you a question?

Is there anything you take care of differently on passenger flights?

Are the cargo room holds always pressurised and air-conditioned?

If any portion of the tube/cylinder that makes up the fuselage is pressurized it all needs to be pressurized.

If there is a flat floor, it cannot withstand pressure pressure only on one side and needs to have equal pressure on both sides.

Cargo holds are pressurized, but not always temperature controlled. Temperature can be controlled if the cargo needs it.
