pressurisation systems in cargo room

[Kate777]

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?

[MechEngr]

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.

[Intruder]

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