The systemcomprises a turbocompressorcomprising an air compressordriven by a turbine. The handling bleed offtakeis in fluid communication with the turbocompressor air turbineto thereby drive the air turbine, and the cabin bleed offtakesare in fluid communication with the turbocompressor air compressorsuch that air from the offtakesis compressed by the turbocompressor air compressor
