alve on both ACM's =o open but that's at 42k feet -The left and right pack inlet=valves go into high flow mode from 25 pounds per min to 26.5 PPM at 13k fe=t -They jump again to 28 PPM to the packs at 23k feet =So the ACM turbine bypass valves and the pack inlet valves are both altitu=e controlled but
