Abstract
A ventilation system for a wide bodied aircraft with pressurization cabin which includes: a compressor apparatus with a heat exchanger for drawing air in from an input reservoir and for generating an excess pressure in at least one output reservoir, several air outlets in the pressurization cabin which are connected to the output reservoir of the compressor apparatus, and at least one suction air intake pipe in the pressurization cabin wherein the volume flow through at least one of the air outlets is adjusted each time by a volume flow control member, as well as to a method for manufacturing a ventilation system of this type. So that errors in the arrangement of the orifice plates in the ducts can be traced, and where applicable remedied, rapidly and without great expense it is proposed according to the disclosed embodiments that the volume flow control member includes: an orifice plate with predetermined internal cross-section in one pipe section, an electronic memory for storing orifice plate parameters and a transmission device for transmitting the orifice plate parameters from the memory to an external receiver device.
