Abstract:
1. A process for controlling the pressure in an aircraft cabin, comprising the steps of: detecting the status of an aircraft door, transmitting a signal indicative of the status of the aircraft door to a unit for controlling an avionics ventilation system and an air conditioning system, the avionics ventilation system cooling an avionics system of the aircraft during operational situations in which sufficiently high pressure prevails in the aircraft cabin and discharging cooling exhaust air from the aircraft cabin, the air conditioning system being adapted to cool the avionics system of the aircraft when less than sufficiently high pressure prevails in the air craft cabin, and controlling the avionics ventilation system in dependence upon the signal indicative of the status of the aircraft door wherein a build-up of pressure in the aircraft cabin is prevented when the signal indicative of the status of the aircraft door indicates that the aircraft door is not fully closed and secured.
