Air conditioning systems (Boeing)
On the 787 each of the four cabin air supply lines has an AH/SC valve. Any one able to tell me what does AH/SC stand for?
On the maintenance page it shows as 0.98 when the compressor is deactivated (I assume this means closed)...in flight it seems to normally show around 0.5.

There is also an AH/SC flow mass.

Thanks in advance
