Hi all,

Looking at FCOM DSC 21-20-30; it quotes a ROC/ROD and a differential of +0.1 PSI in both climb and descent.

My question regarding descent: the aircraft begins a descent and descends the cabin at a ROD. If you are descended very early and fly level for a period does this mean it then stops the cabin descent and maintains the differential at +0.1 PSI? In other words; cabin altitude correlates with aircraft altitude?

Thanks
