Abstract
In controlling pressure in an aircraft cabin, during flight operation, an effective flow cross-sectional area of at least one outflow valve is controlled to adjust air flow exiting the cabin through the outflow valve so pressure within the cabin is controlled according to a predetermined cabin pressure control strategy. During flight operation of the aircraft, an effective flow cross-sectional area of at least one negative relief valve is controlled to adjust air flow entering the cabin through the negative relief valve so a negative differential pressure between the pressure within the aircraft cabin and an ambient pressure prevailing outside of the aircraft cabin is prevented from exceeding a predetermined threshold value. During ground operation of the aircraft, the effective flow cross-sectional area of the at least one negative relief valve is controlled to allow an equalization between pressure within the cabin and ambient pressure prevailing outside of the aircraft.
