Abstract
The flow volume of used air to be discharged from an aircraft cabin is controlled in a valve control system in which each outflow valve has at least two slave controllers responsive to any one of at least two master controllers in a closed loop control system. For this purpose the slave controllers and the master controllers are interconnected by an intermeshed conductor network including a plurality of conductor sections interconnected by electrical conductor junctions or optical conductor couplers forming interfaces between the conductor sections to provide a redundant number of communication paths to keep the system operable even if failures or faults occur.
